Industry trends and perspectives: SNW 2012 Wayne’s World

This is a StorageIO industry trends and perspective audio blog and pod cast about Storage Networking World (SNW) Fall 2012 in Santa Clara California.

Given how at conference conversations tend to occur in the hallways, lobbies and bar areas of venues, what better place to have candid conversations with people from throughout the industry, some you know, some you will get to know better.

In this episode, I’m joined by my co-host Bruce Rave aka Bruce Ravid of Ravid & Associates as we catch up and visit with SNIA Chairman Wayne Adams in the Santa Clara Hyatt (event venue) lobby bar area.

Click here (right-click to download MP3 file) or on the microphone image to listen to the conversation with Wayne, Bruce. Our conversations covers SNW past and present, global SNW and travel, technology and the importance of networking, that is meeting and talking with people during these events.

I often hear people say how small the storage and networking (or other adjacent technology) industries are, and how everybody knows everyone. That might be true in some circles or sub-communities where everybody knows each other, however the industry is larger than many realize. As you listen to these series of pod casts what you will hear is a recurring theme of people meeting others at events, including some who may have passed each other in hallways for years yet never have had a chance to meet, or put a name to a face.

While modern communications, social networking and other advances make the world a smaller place and reducing your degrees of separation with others (and your information), there is still plenty off opportunities to meet those you have not yet meet. Watch (and listen) for more StorageIO industry trends and perspectives audio blog posts pod casts from SNW and other upcoming events.

Enjoy listening to SNW 2012 Wayne’s World.

How many degrees separate you and your information?

In case you are not familiar, degrees of separation refer to how you are connected to other people.

When you know somebody directly then you are a first connection, and you are a second degree of separation from people that they are directly connected to. The theory goes that via a mix of the number of people you are directly connected to, as well as how well they are connected to others, that you are only so many degrees of connection separation from many (if not millions of people) and if you go out seven degrees, that could be billions.

If you are familiar with or use Linked In and are directly connected to somebody like myself, which is a first degree. For example in the following image, person A is a first or 1 degree connection to person B, person B is a direct or first degree connection to person C who in turn is a direct connection to person D. Person A is 2 degree from person C and three degree from person D.

The reason I bring this up is not to say or play games around who is connected to whom, or compare contacts or the number of them, rather to use the idea of degrees of separation in the context of where and how you get your information. For example, you may get your information, insight or experience directly from what you do. On the other hand, you may get information or knowledge directly from the source or person involved with it, which would be 1 degree of separation.

You could also get the information from somebody else such as a friend, coworker, blogger, analyst, consultant, media journalist, reporter, vendor, VAR or other person who got it directly from the source, which would be 2 degrees of separation. Another example would be you get your information from somebody who cites a report, study, survey or some research that came from another source that involved another party who collected and analyzed the data.

At each point, there is the potential for the information to be changed, adjusted, reinterpreted, misunderstood, or simply adapted to meet particularly needs. What if person A gets their information from person B who in turn got their information from source C, and that comes from person D who got it directly from person E? Assuming that the information was collected and passed along as is, person A should get what was given from person E to person D. However, along the way, various interpretations, more material and views can be applied resulting in a different message.

There is also another variation, which are your spheres of influence or circles of contacts. For example I get to talk with lots of IT pros around the world live in person, virtually and via different venues, those would be direct or no separation. When I hear from a vendor or PR or some pundit telling me what they heard direct, that’s 1 degree however if they heard it from their marketing who heard it from a sales rep or other source then it’s at least two.

Another example of degrees of separation is where you are in relation to technology timelines, evolution, revolution, industry adoption vs. customer deployment. For example, if you are a researcher or development engineer, you are further along on a technology evolution curve than others are. Somebody then takes the researchers work and productize it including making it manufacture able on a cost-effective basis. Along the lines there is also the different degrees of separation between the researcher, initial publicity of a technology breakthrough, general industry adoption and later customer deploy and subsequent success stories. For example, to a research something that they did many years along with those who follow at that point may view what is emerging for real customer deploy as old and yesterday’s news.

On the other hand, for customers getting ready to deploy a new technology, product or service, some breaking research may be interesting to hear about, however it may be out several years at best from customer actual use. Also on that theme, the customer of a component can be a manufacturer that in turn test, qualifies and sells a finished solution to their customers. Thus, there are different degrees of separation between industry adoption (e.g. talking about and awareness) and customer deployment (actually buying and using on a mainstream basis) in the technology supply chain.

Yet another degree of separation is between you and your information or data. Some of that data is very close in your own memory (e.g. brain), perhaps others written on note pads (physical or digital) with a copy local or remote including at the cloud. Depending on how your data and information are backed up or protected, there can be added degrees of separation between you and your information.

Thus, there are different degrees of separation between you and your various forms of information.

Your ability to learn and share information, meet and interact with various people from across different sections of environments is bound by what you are willing to engage via various mediums including social media involvement.

If you are comfortable with where you are at, or what you know, then stay in your comfort zone, or sphere of influence, otherwise, take a chance, venture out, learn what you do not know, meet who you do not know, interact and see new things, or have some dejavu and share what you have seen or experienced before.

After all, knowledge not shared with others is useless if kept only to you. Of course, for NDA material, what is not generally known about, or understood is not discussed and let us leave sleeping dogs lay where they rest. ;)

How good or reliable is your information or G2 that you might be using for forming opinions or making informed decisions around?

Feel free to expand your network getting closer by a degree or two, if not directly too different sources. You can connect with me via Twitter (@storageio), Goggle+, Linked In and Facebook among other means here. Likewise, check out the StorageIO events calendar here for upcoming virtual and live activities.

RAID and IOPS and IO observations

Storage I/O trends

There are at least two different meanings for IOPs, which for those not familiar with the information technology (IT) and data storage meaning is Input/output Operations Per second (e.g. data movement activity). Another meaning for IOP that is the international organization for a participatory society (iopsociety.org), and their fundraising activity found here.

I recently came across a piece (here and here) talking about RAID and IOPs that had some interesting points; however, some generalizations could use some more comments. One of the interesting comments and assertions is that RAID writes increase with the number of drives in the parity scheme. Granted the specific implementation and configuration could result in an it depends type response.

StorageIO industry trends cloud, virtualization and big data

Here are some more perspectives to the piece (here and here) as the sites comments seem to be restricted.

Keep in mind that such as with RAID 5 (or 6) performance, your IO size will have a bearing on if you are doing those extra back-end IOs. For example if you are writing a 32KB item that is accomplished by a single front-end IO from an applications server, and your storage system, appliance, adapter, software implementing and performing the RAID (or erasure coding for that matter) has a chunk size of say 8KB (e.g. the amount of data written to each back-end drive). Then a 5 drive R5 (e.g. 4+1) would in fact have five back-end IOPS (32KB / 8KB = 4 + 1 (8KB Parity)).

StorageIO industry trends cloud, virtualization and big data

Otoh of the front end IOP were only 16KB (using whole numbers for simplicity, otherwise round-up), in the case of a write, there would be three back-end writes with the R5 (e.g. 2 + 1). Keep in mind the controller/software managing the RAID would (or should) try to schedule back-end IO with cache, read-head, write-behind, write-back, other forms of optimization etc.

In the piece (here and here), a good point is the understanding and factoring in IOPS is important, as is also latency or response time in addition to bandwidth or throughput, along with availability, they are all inter-related.

Also very important is to keep in mind the size of the IOP, read and write, random, sequential etc.

RAID along with erasure coding is a balancing act between performance, availability, space capacity and economics aligned to different application needs.

RAID 0 (R0) actually has a big impact on performance, no penalty on writes; however, it has no availability protection benefit and in fact can be a single point of failure (e.g. loss of a HDD or SSD) impacts the entire R0 group. However, for static items, or items that are being journaled and protected on some other medium/RAID/protection scheme, R0 is used more than people realize for scratch/buffer/transient/read cache types of applications. Keep in mind that it is a balance of all performance and capacity with the exposure of no availability as opposed to other approaches. Thus, do not be scared of R0, however also do not get burned or hurt with it either, treat it with respect and can be effective for something’s.

Also mentioned in the piece was that SSD based servers will perform vastly better than SATA or SAS based ones. I am assuming that the authors meant to say better than SAS or SATA DAS based HDDs?

Storage I/O trends

Keep in mind that unless you are using a PCIe nand flash SSD card as a target or cache or RAID card, most SSD drives today are either SAS or SATA (being the more common) along with moving from 3Gb SAS or SATA to 6Gb SAS & SATA.

Also while HDD and SSDs can do a given number of reads or writes per second, those will vary based on the size of the IO, read, write, random, sequential. However what can have the biggest impact and where I have seen too many people or environments get into a performance jam is when assuming that those IOP numbers per HDD or SSD are a given. For example assuming that 100-140, IOPs (regardless of size, type, etc.) can be achieved as a limiting factor is the type of interface and controller/adapter being used.

I have seen fast HDDs and SSDs deliver sub-par performance or not meeting expectations fast interfaces such as iSCSI/SAS/SATA/FC/FCoE/IBA or other interfaces due to bottlenecks in the adapter card, storage system / appliance / controller / software. In some cases you may see more effective IOPs or reads, writes or both, while on other implementations you may see lower than expected due to internal implementation bottlenecks or architectural designs. Hint, watch out for solutions where the vendor tries to blame poor performance on the access network (e.g. SAS, iSCSI, FC, etc.) particular if you know that those are not bottlenecks.

Does Dell have a cloudy cloud strategy story (Part II)?

StorageIO industry trends cloud, virtualization and big data

This is the second of two posts (here is the first post) that are part of ongoing industry trends and perspectives cloud conversations series that looks at Dell and their cloud strategy story.

So what does the first post have to do with Dell having a cloudy cloud strategy story?

Simple, there have been some rather low-key, almost quiet or muddled announcements (also here, here and here) about Dell and Nirvanix collaborating around public cloud storage. Keep in mind that Nirvanix and IBM not too long ago also announced a partnership that some jumped to the conclusion that big blue was about to buy the startup vendor, even though IBM already has other cloud and storage as a service, or backup as a service and DR as a service offerings, what the heck, the more the merrier for big blue?

What about Dell and their partnership with Nirvanix, (more on that in the first post) did somebody jump the gun, or jump the shark?

Is Dell trying to walk the tightrope between being a supplier to major cloud providers while carefully moving into the cloud services market themselves, or are they simply addressing point customer situation or opportunities, at least for the time being?

Alternatively, is this nothing more than Dell establishing another partnership with a technology partner who also happens to be in the services business, similar to what Dell is doing with OpenStack and others?

IMHO Dell has some of the pieces and partnerships and could be a strong contender in the SMB and SME private cloud space, along with VDI and related areas with their Citrix, Microsoft and VMware partnerships. This is also also leveraging their servers and, storage, software, networking and other solutions to supply service providers.

The rest comes down to what markets or areas of focus does Dell want to target, that would in turn dictate how to extend what they already have or what they need to go out and get or partner around.

What say you, what’s your take on Dells cloud strategy story and portfolio?

Ok, nuff said (for now).

Does Dell have a cloudy cloud strategy story (Part I)?

StorageIO industry trends cloud, virtualization and big data

This is first of a two-part post (click here for second post) that is part of ongoing industry trends and perspective cloud conversations series that looks at Dell and their cloud strategy story. For background, some previous Dell posts are found here, here, here and here. Here is a link that has video of the live Dell Storage Customer Advisory (CAP) panel that Dell asked me to moderate back in June that touches on some related themes and topics. Btw, fwiw and for disclosure Dell AppAssure is a site advertiser on storageioblog.com ;).

Depending on your view of what is or is not a cloud service, product or solution, naturally you will then have various opinions of where Dell is at with their cloud strategy and story.

If you consider object based storage to be part of or a component of private clouds or at least for medical, healthcare and related focus, then Dell is already there with their DX object storage solutions (Caringo based).

From a scale out, clustered or grid file system, Dell bought Exanet in a post holiday shopping sale a few years back and has invested in its development having renamed it Fluid File System and initially available as the FS7000 series (EqualLogic) and more recently expanded systems such as the FS8600 (Compellent based), EqualLogic and NX3500 (MD3000 based).

If you view clouds as being part of services provided including via hosting or similar, Dell is already there via their Perot systems acquisitions.

If you view cloud as being part of VDI, or VDI being part of cloud, Dell is there with their tools including various acquisitions and solution bundles.

On the other hand if you view clouds as reference architectures across VMware vSphere, Microsoft Hyper-V and Citrix Xen among others, guess what, Dell is also there with their VIS.

Or, if you view private clouds as being a bundled solution (server, storage, hardware, software) such as EMC vBlock or NetApp FlexPod, then Dell vStart (not to be confused as being a service) is on the list with other infrastructure stack solutions.

How about being a technology supplier to what you may consider as being true cloud providers or enables including those who use OpenStack or other APIs and cloud tools, guess what, Dell is also there including at Rackspace (via public web info).

So the above all comes back to that Dell like many vendors who offer services, solutions and related items for data and information infrastructures have diverse offerings including servers, storage, networking, hardware, software and support. Dell like others similar to them has to find a balance between providing services that compete with their customers, as well as supplier such as to Rackspace. In this case Dell is no different from EMC who happened to move their Mozy backup service off to their VMware subsidiary and has managed to help define where VCE (and here) and ATMOS fit as products while being services capable. IBM has figured this out having a mix of old school services such as SmartCloud Services (or here), IBM Global Services and BCRS (business continuity recovery services), not to mention newer backup and storage cloud services, products and solutions they have acquired, or OEM or have reseller agreements with.

StorageIO industry trends cloud, virtualization and big data

HP has expanded their traditional focused EDS as well as other HP services along with products being joined by their Amazon like Cloud Services including compute, storage and content distribution network (CDN) capabilities. NetApp is taking the partnering route along with Cisco staying focused for at least now on being a partner supplier. Oracle, well Oracle is Oracle and they have a mix of products and services. In fact some might say Oracle is late to the cloud game however they have been in the game since the late 90s when they came out with Oracle online, granted the cloud purist will call that application service provider (e.g. ASP) vs. today’s applications as a service (AaaS) models.

Continue with the second post here, ok, nuff said (for now).

StorageIO going Dutch and Deutsch fall 2012

StorageIO industry trends cloud, virtualization and big data

Following a busy spring and summer schedule, the fall 2012 StorageIO out and about activities are underway including events on both the European and North American continents.

In addition to in person events, there are also some virtual activities including live and recorded video and audio sessions, as well as webcast on the fall schedule with more in the works.

Some of the fall events include SNW (past SNW posts here, here, and here) in Santa Clara, as well as SNW Europe and Power the Cloud event (Frankfurt Deutschland aka Germany) October 30 and 31st where I will be doing some meetings and briefing, along with attending sessions and the expo activities.

On November 1st its off to Storage Expo Holland in Utrecht (here and here) where I will be presenting two sessions. One is on SSD industry trends and tips on deployment with a theme of not if, rather when, where, why and with what to use SSD. In addition I will be doing a general industry trends and perspective session on gaining confidence with clouds, virtualization, data and storage networking including object storage and backup (e.g. data protection modernization).

European travel tools and technologies

In addition to the above activities, following successful past events in Nijkerk Holland including the most recent May 2012 sessions, a new seminar has been announced focused on backup, restore, BC, DR and archiving hosted by Brouwer Consultancy on November 5th and 6th 2012. These workshop format seminars are very interactive providing independent perspectives on technology, tools, trends and what to do to address various challenges including more informed and effective IT decision-making.

Greg in action Nijkerk Storage Seminar

In addition to the new seminar that you can learn more about here, two other sessions will also be offered in Holland. These include a backup, restore, BC, DR and archiving. The other session is a backup, restore, BC, DR and archiving covering storage and networking industry trends covering clouds, virtualization and other broad topics.

Examples of Dutch refreshments

Learn more about the dutch seminars including how to register here.

Watch for more events, seminars, live video, webinars and virtual trade shows by visiting the StorageIO events page.

Drop me a note if you would like to schedule or arrange for a meeting, webinar, seminar or other activity at an event near you. If you planning to be in or near Holland early November, and interested in scheduling a meeting or session, send me a note or contact Brouwer Consultancy (here) to make arrangements.

Time to get ready for these and other events, ok, nuff said.

Cloud, virtualization, storage and networking in an election year

My how time flies, seems like just yesterday (back in 2008) that I did a piece titled Politics and Storage, or, storage in an election year V2.008 and if you are not aware, it is 2012 and thus an election year in the U.S. as well as in many other parts of the world. Being an election year it’s not just about politicians, their supporters, pundits, surrogates, donors and voters, it’s also a technology decision-making and acquisition year (as are most years) for many environments.

Similar to politics, some technology decisions will be major while others will be minor or renewals so to speak. Major decisions will evolve around strategies, architectures, visions, implementation plans and technology selections including products, protocols, processes, people, vendors or suppliers and services for traditional, virtual and cloud data infrastructure environments.

Vendors, suppliers, service providers and their associated industry forums or alliances and trade groups are in various sales and marketing awareness campaigns. These various campaigns will decide who will be chosen by their customers or prospects for technology acquisitions ranging from hardware, software and services including servers, storage, IO and networking, desktops, power, cooling, facilities, management tools, virtualization and cloud products and services along with related items.

The politics of data infrastructures including servers, storage, networking, hardware, software and services spanning physical, cloud and virtual environments has similarities to other political races. These include many organizations in the form of inter departmental rivalry over budgets or funding, service levels, decision-making, turf wars and technology ownership not to mention the usual vendor vs. vendor, VAR vs. VAR, service provider vs. service provider or other match ups.

On the other hand, data and storage are also being used to support political campaigns in many ways across physical, virtual and cloud deployment scenarios.

StorageIO industry trends cloud, virtualization and big data

Let us not forget about the conventions or what are more commonly known as shows, conferences, user group events in the IT world. For example EMCworld earlier this year, Dell Storage Forum, or the recent VMworld (or click here to view video from past VMworld party with INXS), Oracle Open World along with many vendor analyst, partner, press and media or blogger days.

Here are some 2012 politics of data infrastructure and storage campaign match-ups:

Vendor lock in, is it a problem and who is responsible
Replication and snapshots vs. Backup vs. data protection modernization
Erasure codes vs. RAID
Public vs. Private and hybrid clouds
Cloud products vs. cloud APIs vs. cloud services
IBM and the Better Business Bureau vs. Oracle marketing claims
Cloud confidence vs. cloud data loss vs. loss of access
Taking shared responsibility for data protection vs. blaming others
Bring your own device (BYOD) vs. IT supplied
VDI vs. Physical and traditional desktops including windows performance
EMC vs NetApp in the race for unified or anything else storage related
Big iron vs. little iron vs. virtual iron or software defined
EMC vs. Oracle in the race for big data buzz
Environmental focused vs. economic and productivity enabling Green IT
Green IT myths and missed opportunities
Oracle vs. IBM in the race for big data and little data (databases)
Clusters, clouds and grids vs. traditional architectures
Seagate vs. Western Digital (WD) in the race for Hard Disk Drives (HDD)
Hard vs. soft products and services
SSD vs. HDD vs. HHDD and SSD startups vs. established vendors
EMC and Lenovo vs. Dell, HP, IBM, NetApp and others
Industry adoption vs. industry deployment
PCIe SSD vendors vs. storage array and appliance vendors
Nand flash vs. any new SSD entrants for persistent memory
Consolidate everything vs. virtualize many things
SAN, NAS or Unified vs. Cloud object vs. DAS vs. SAS vs. FCoE
Microsoft Hyper-V and Citrix Xen and KVM vs. VMware vSphere
Microsoft, HP and others vs. Amazon and Goggle for cloud supremacy
Edgy vs. civility, G2 vs. GQ, entertainment vs. education
Fear and FUD vs. credibility and confidence
Samsung vs. Apple lawsuit(s) part deux
IOV, SDN, and software defined anything vs. hardware defined anything

Speaking of networks vs. server and storage or software and convergence, how about Brocade vs. Cisco, Qlogic vs. Emulex, Broadcom vs. Mellanox, Juniper vs. HP and Dell (Force10) or Arista vs. others in the race for SAN LAN MAN WAN POTS and PANs.

Then there are the claims, counter claims, pundits, media, bloggers, trade groups or lobbyist, marketing alliance or pacs, paid for ads and posts, tweets and videos along with supporting metrics for traditional and social media.

Lets also not forget about polls, and more polls.

Certainly, there are vendors vs. vendors relying on their campaign teams (sales, marketing, engineering, financing and external surrogates) similar to what you would find with a politician, of course scope, size and complexity would vary.

Surrogates include analyst, bloggers, consultants, business partners, community organizers, editors, VARs, influencers, press, public relations and publications among others. Some claim to be objective and free of vendor influence while leveraging simple to complex schemes for renumeration (e.g. getting paid) while others simply state what they are doing and with whom.

Likewise, some point fingers at others who are misbehaving while deflecting away from what they are actually doing. Hmm, sounds like the pundit or surrogate two-step (as opposed to the Potomac two step) and prompts the question of who is checking the fact checkers and making disclosures (disclosure: this piece is being sponsored by StorageIO ;) )?

StorageIO industry trends cloud, virtualization and big data

What this all means?

Use your brain, use your eyes and ears, and use your nose all of which have dual paths to your senses.

In other words, if something sounds or looks too good to be true, it probably isn’t.

Likewise if something smells funny or does not feel right to your senses or common sense, it probably is not or at least requires a closer look or analysis.

Be an informed decision maker balancing needs vs. wants to make effective selections regardless of if for a major or minor item, technology, trend, product, process, protocol or service. Informed decisions also mean looking at both current and evolving or future trends, challenges and needs which for data infrastructures including servers, storage, networking, IO fabrics, cloud and virtualization means factoring in changing data and information life cycles and access or usage patterns. After all, while there are tough economic times on a global basis, there is no such thing as a data or information recession.

This also means gaining insight and awareness of issues and challenges, plus balancing awareness and knowledge (G2) vs. looks, appearances and campaign sales pitches (GQ) for your particular environment, priorities and preferences.

Keep in mind and in the spirit of legendary Chicago style voting, when it comes to storage and data infrastructure topics, technologies and decisions, spend early, spend often and spend for those who cannot to keep the vendors and their ecosystem of partners happy.

Note that this post is neither supported, influenced, endorsed or paid for by any vendors, VARs, service providers, trade groups, political action committees or Picture Archive Communication system (e.g. PACs), both of which deal with and in big data along with industry consortiums, their partners, customers or surrogates and neither would they probably approve of it anyway’s.

With that being said, I am Greg Schulz of StorageIO and am not running for or from anything this year and I do endorse the above post ;).

Ok, nuff said for now

Cloud conversations: confidence, certainty and confidentiality

Here is an interesting article from over at wired about proposed privacy law and court warrants for cloud data, along with this one over at information week. Both got me thinking about some things that I hear when out and about talking with IT professionals and their concerns around clouds.

StorageIO industry trends cloud, virtualization and big data

Common themes at the recent modernizing data protection and new realities of cloud and virtualization event series that I was involved with pertained to cloud concerns. Some organizations are already using clouds to some degree while others are taking a cautious approach. Some are all in, while others will take longer for various reasons. Likewise some are using a mix of public, private and hybrid to compliment their environments for collaboration, shared storage, compute, content distribution, backup, archive or BC and DR among other things. These environments range from SOHO or small SMB to ROBO to workgroup to enterprise, education and government of various size.

Often the conversations would evolve around gaining confidence with clouds as well as virtualization. In the case of clouds, given that some of the services as well as products, solutions or technologies are still young, there is still a learning and maturing curve. There are also other factors including the amount of hype and FUD around clouds has some people more skeptical or cautious to move forward. Granted there are also the true cynics which tend to be offset by the cloud crowd cheerleaders thus canceling each other out.

For the non cheerleaders and non cynics, hurdles to cloud adoption (in whole or in part, public, private or hybrid) tend to start with the letter C.

My message has and continues to be that of do not be scared of clouds and virtualization, however be ready, informed and decide what your concerns are. By determining your concerns, you can then work on figuring out what to do about those.

Here is a list of common cloud concerns and comments that I hear:
Cloud cheerleader hype
Cloud critics and cynics FUD
Confidence in cloud products or services
Certainty in cloud data protection or security
Cloud certifications and standards
Compatibility and interoperability
Classes and continuing education
Confidentially, privacy and security
Costs of cloud services or products
Country where cloud data is stored

There are many other items that can be added to the list that start with the letter C, however there are also some that start with P. For example, People, Products, Process, Procedures, Practices, Paradigm, Public or Private and Protocols among others.

Its one thing to be scared of something and not know what or why you are scared. It’s another thing to know or figure out what or why you are scared or concerned and then be able to do something about it. For example learn what standards such as SNIA CDMI among others exist and how those could be of help along with other tools or best practices from others.

Thus don’t be scared of clouds or virtualization, however do your homework, decide your concerns and then find what can be done about those. If you need help, drop me a note.

In the meantime, here is some more material:
Cloud and Virtual Data Storage Networking
More modernizing data protection, virtualization and clouds with certainty
Cloud conversations: AWS Government Cloud (GovCloud)
Amazon cloud storage options enhanced with Glacier
Open Data Center Alliance (ODCA) publishes two new cloud usage models
Data protection modernization, more than swapping out media

More modernizing data protection, virtualization and clouds with certainty

This is a follow-up to a recent post about modernizing data protection and doing more than simply swapping out media or mediums like flat tires on a car as well as part of the Quantum protecting data with certainty event series.

As part of a recent 15 city event series sponsored by Quantum (that was a disclosure btw ;) ) titled Virtualization, Cloud and the New Realities for Data Protection that had a theme of strategies and technologies that will help you adapt to a changing IT environment I was asked to present a keynote at the events around Modernizing data protection for cloud, virtual and legacy environments (see earlier and related posts here and here).

Since late June (taking July and most of August off) and wrapping up last week, the event series has traveled to Boston, Chicago, Palo Alto, Houston, New York City, Cleveland, Raleigh, Atlanta, Washington DC, San Diego, Los Angeles, Mohegan Sun CT, St. Louis, Portland Oregon and King of Prussia (Philadelphia area).

The following are a series of posts via IT Knowledge Exchange (ITKE) that covered these events including commentary and perspectives from myself and others.

Data protection in the cloud, summary of the events
Practical solutions for data protection challenges
Big data’s new and old realities
Can you afford to gamble on data protection
Conversations in and around modernizing data protection
Can you afford not to use cloud based data protection

In addition to the themes in the above links, here are some more images, thoughts and perspectives from while being out and about at these and other events.

Datalink does your data center suck sign
While I was traveling saw this advertisement sign from Datalink (who is a Quantum partner that participated in some of the events) in a few different airports which is a variation of the Datadomain tape sucks attention getter. For those not familiar, that creature on the right is an oversized mosquito with the company logos on the lower left being Datalink, NetApp, Cisco and VMware.

When in Atlanta for one of the events at the Morton’s in the Sun trust plaza, the above sculpture was in the lobby. Its real title is the goddess of fertility, however I’m going to refer to it as the goddess of data fertility, after all, there is no such thing as a data or information recession.

Traveling while out and about is like a lot of things particular IT and data infrastructure related which is hurry up and wait. Not only does America Run on Dunkin, so to does StorageIO.

Use your imagination
When out and about, sometimes instead of looking up, or around, take a moment and look down and see what is under your feet, then let your imagination go for a moment about what it means. Ok, nuff of that, drink your coffee and let’s get back to things shall we.

Delta 757 and PW2037 or PW2040
Just like virtualization and clouds, airplanes need physical engines to power them which have to be energy-efficient and effective. This means being very reliable, good performance, fuel-efficient (e.g. a 757 on a 1,500 mile trip if full can be in the neighborhood of 65 plus miles per gallon per passenger with a low latency (e.g. fast trip). In this case, a Pratt and Whitney PW2037 (could be a PW2040 as Delta has a few of them) on a Delta 757 is seen powering this flight as it climbs out of LAX on a Friday morning after one of the event series session the evening before in LA.

Ambulance waiting at casino
Not sure what to make out of this image, however it was taken while walking into the Mohegan Sun casino where we did one of the dinner events at the Michael Jordan restaraunt

David Chapa of Quantum in bank vault
Here is an image from one of the events in this series which is a restaurant in Cleveland where the vault is a dinning room. No that is not a banker, well perhaps a data protection banker, it is the one and only (@davidchapa) David Chapa aka the Chief Technology Evangelist (CTE) of Quantum, check out his blog here.

Nice view just before landing in Portland Oregon where that evenings topic was as you might have guessed, data protection modernization, clouds and virtualization. Don’t be scared, be ready, learn and find concerns to overcome them to have certainty with data protection in cloud, virtual and physical environments.
Teamwork
Cloud, virtualization and data protection modernization is a shared responsibility requiring team work and cooperation between service or solution provider and the user or consumer. If the customer or consumer of a service is using the right tools, technologies, best practices and having had done their homework for applicable levels of services with SLAs and SLOs, then a service provider with good capabilities should be in harmony with each other. Of course having the right technologies and tools for the task at hand is also important.
Underground hallway connecting LAX terminals, path to the clouds
Moving your data to the cloud or a virtualized environment should not feel like a walk down a long hallway, that is assuming you have done your homework, that the service is safe and secure, well taken care of, there should be less of concerns. Now if that is a dark, dirty, dingy, dilapidated dungeon like hallway, then you just might be on the highway to hell vs. stairway to heaven or clouds ;).

clouds along california coastline
There continues to be barriers to cloud adoption and deployment for data protection among other users.

Unlike the mountain ranges inland from the LA area coastline causing a barrier for the marine layer clouds rolling further inland, many IT related barriers can be overcome. The key to overcoming cloud concerns and barriers is identifying and understanding what they are so that resolutions, solutions, best practices, tools or work around’s can be developed or put into place.

The world and storageio runs on dunkin donuts
Hmm, breakfast of champions and road warriors, Dunkin Donuts aka DD, not to be confused with DDUP the former ticker symbol of Datadomain.

Tiered coffee
In the spirit of not treating everything the same, have different technology or tools to meet various needs or requirements, it only makes sense that there are various hot beverage options including hot water for tea, regular and decaffeinated coffee. Hmm, tiered hot beverages?

On the lighter side, things including technology of all type will and do break, even with maintenance, so having a standby plan, or support service to call can come in handy. In this case the vehicle on the right did not hit the garage door that came off of its tracks due to wear and tear as I was preparing to leave for one of the data protection events. Note to self, consider going from bi-annual garage door preventive maintenance to annual service check-up.

Some salesman talking on phone in a quiet zone

While not part of or pertaining to data protection, clouds, virtualization, storage or data infrastructure topics, the above photo was taken while in a quiet section of an airport lounge waiting for a flight to one of the events. This falls in the class of a picture is worth a thousand words category as the sign just to the left of the sales person talking loudly on his cell phone about his big successful customer call says Quiet Zone with symbol of no cell phone conversations.

How do I know the guy was not talking about clouds, virtualization, data infrastructure or storage related topics? Simple, his conversation was so loud me and everybody else in the lounge could hear the details of the customer conversation as it was being relayed back to sales management.

Note to those involved in sales or customer related topics, be careful of your conversations in public and pseudo public places including airports, airport lounges, airplanes, trains, planes, hotel lobbies and other places, you never know who you will be broadcasting to.

Here is a link to a summary of the events along with common questions, thoughts and perspectives.

Thanks to everyone who participated in the events including attendees, as well as Quantum and their partners for sponsoring this event series, look forward to see you while out and about at some future event or venue.

Ok, nuff said.

Who will be winner with Oracle $10 Million dollar challenge?

Oracle 10 million dollar challenge ad image

In case you missed it, Oracle has a ten million dollar challenge (here, here and here) to prove that their servers and database software technologies are 5 times faster than IBM.

Up to 10 winners open to U.S. Fortune 1000 companies running an Oracle 11g data warehouse on IBM Power system. Offer expires August 31, 2012 with configuration terms. See this URL for official rules: https://oracle.com/IBMchallenge

Click here to view entry form or click on form below.

Oracle 10 million dollar challenge entry form image

Taking a step back for a moment, if you forgot or had not heard, Oracle earlier this summer had their hands slapped by the US Better Business Bureau (BBB) National Advertising Directive (NAD) over performance claims and ads. IBM complained to the BBB that unfair marketing claims about their servers and database products were being made by Oracle (read more here).

Not one to miss a beat or bit or byte of data, not to mention dollars, Oracle has run ads in newspapers and other venues for the Oracle IBM challenge with the winner receiving $10,000,000.00 USD (details here).

This begs the question, who wins, the company or entity that actually can standup and meet the challenge? How about Oracle, do they win if enough people see, hear, talk (or complain) about the ads and challenges? What about the cost, how will Oracle cover that or is it simply a drop in the bucket of an even larger amount of dollars potentially valued in the billions of dollars (e.g. servers, storage, software, services)?

Now for some fun, using an inflation calculator with 1974 dollars as that is when the TV show the six million dollar man made its debut. If you do not know, that is a TV show where an injured government employee (Steve Austin) played by actor Lee Majors was rebuilt using bionic in order to be faster and stronger with the then current technology (ok, TV technology). Using the inflation calculator, the 1974 six million dollar man and machine would cost about $27,882,839.76 in 2012 USD (364.7% increase).

Now using todays what Oracle is calling faster, stronger machine and associated staff for $10,000,000 challenge prize award, would have cost $2,151,861.17 in 1974 dollars. Note that the equal amount of compute processing, storage performance and capacity, networking capability and software abilities in 1974 similar to what is available today would have cost even more than what the inflation calculator shows. For that, we would need to have something like a technology inflation (or improvement) calculator.

Learn more about the Oracle challenge here, here and here, as well as the NAD announcement here, and the six million dollar man here

Ok, nuff said for now.

Cloud conversations: AWS Government Cloud (GovCloud)

Following earlier cloud conversations posts, cloud computing means many things from products to services, functionality and positioned for different layers of service delivery or capabilities (e.g. SaaS, AaaS, PaaS, IaaS and XaaS).

Consequently it is no surprise when I hear from different people their opinion, belief or perception of what is or is not a cloud, confidence or concerns, or how to use and abuse clouds among other related themes.

A common theme I hear talking with IT professionals on a global basis centers around conversations about confidence in clouds including reliability, security, privacy, compliance and confidentiality for where data is protected and preserved. This includes data being stored in different geography locations ranging from states or regions to countries and continents. What I also often hear are discussion around concerns over data from counties outside of the US being stored in the US or vice versa of information privacy laws.

Cost is also coming up in many conversations, which is interesting in that many first value propositions have been presented around cloud being cheaper. As with many things it depends, some services and usage models can be cheaper on a relative basis, just like some can be more expensive. Think of it this way, for some people a lease of an automobile can cheaper on monthly cash flow vs. buying or making loan payments. On the other hand, a buy or loan payment can have a lower overall cost depending on different factors then a lease.

As with many cloud conversations, cost and return on investment (ROI) will vary, just as how the cloud is used to impact your return on innovation (the new ROI) will also vary.

This brings me to something else I hear during my travels and in other conversations with IT; practitioners (e.g. customers and users as well as industry pundits) is a belief that governments cannot use clouds. Again, it depends on what type of government, the applications, sensitivity of data among others factors.

Some FUD (Fear uncertainty doubt) I hear includes blanket statements such as governments cannot use cloud services or cloud services do not exist for governments. Again it comes down to digging deeper into the conversation such as what type of cloud, applications, government function, security and sensitivity among other factors.

Keep in mind that there are services including those from Amazon Web Services (AWS) such as their Government Cloud (GovCloud) region. Granted, GovCloud is not applicable to all government cloud needs or types of applications or data or security clearances among other concerns.

Needless to say AWS GovCloud is not the only solution out there on a public (government focused), private or hybrid basis, there are probably even some super double secret ultra-private or hybrid fortified government clouds that most in the government including experts are not aware of. However if those do exist, certainly talking about them is also probably off-limits for discussions even by the experts.

Speaking of AWS, here is a link to an analysis of their cloud storage for archiving and inactive big data called Glacier, along with analysis of AWS Cloud Storage Gateway. Also, keep in mind that protecting data in the cloud is a shared responsibility meaning there are things both you as the user or consumer as well as the provider need to do.

Btw, what is your take on clouds? Click here to cast your vote and see what others are thinking about clouds.

Ok, nuff said for now.

Amazon cloud storage options enhanced with Glacier

In case you missed it, Amazon Web Services (AWS) has enhanced their cloud services (Elastic Cloud Compute or EC2) along with storage offerings. These include Relational Database Service (RDS), DynamoDB, Elastic Block Store (EBS), and Simple Storage Service (S3). Enhancements include new functionality along with availability or reliability in the wake of recent events (outages or service disruptions). Earlier this year AWS announced their Cloud Storage Gateway solution that you can read an analysis here. More recently AWS announced provisioned IOPS among other enhancements (see AWS whats new page here).

Before announcing Glacier, options for Amazon storage services relied on general purpose S3, or EBS with other Amazon services. S3 has provided users the ability to select different availability zones (e.g. geographical regions where data is stored) along with level of reliability for different price points for their applications or services being offered.

Note that AWS S3 flexibility lends itself to individuals or organizations using it for various purposes. This ranges from storing backup or file sharing data to being used as a target for other cloud services. S3 pricing options vary depending on which availability zones you select as well as if standard or reduced redundancy. As its name implies, reduced redundancy trades lower availability recovery time objective (RTO) in exchange for lower cost per given amount of space capacity.

AWS has now announced a new class or tier of storage service called Glacier, which as its name implies moves very slow and capable of supporting large amounts of data. In other words, targeting inactive or seldom accessed data where emphasis is on ultra-low cost in exchange for a longer RTO. In exchange for an RTO that AWS is stating that it can be measured in hours, your monthly storage cost can be as low as 1 cent per GByte or about 12 cents per year per GByte plus any extra fees (See here).

Here is a note that I received from the Amazon Web Services (AWS) team:

Dear Amazon Web Services Customer,
We are excited to announce the immediate availability of Amazon Glacier – a secure, reliable and extremely low cost storage service designed for data archiving and backup. Amazon Glacier is designed for data that is infrequently accessed, yet still important to keep for future reference. Examples include digital media archives, financial and healthcare records, raw genomic sequence data, long-term database backups, and data that must be retained for regulatory compliance. With Amazon Glacier, customers can reliably and durably store large or small amounts of data for as little as $0.01/GB/month. As with all Amazon Web Services, you pay only for what you use, and there are no up-front expenses or long-term commitments.

Amazon Glacier is:

Low cost– Amazon Glacier is an extremely low-cost, pay-as-you-go storage service that can cost as little as $0.01 per gigabyte per month, irrespective of how much data you store.
Secure – Amazon Glacier supports secure transfer of your data over Secure Sockets Layer (SSL) and automatically stores data encrypted at rest using Advanced Encryption Standard (AES) 256, a secure symmetrix-key encryption standard using 256-bit encryption keys.
Durable– Amazon Glacier is designed to give average annual durability of 99.999999999% for each item stored.
Flexible -Amazon Glacier scales to meet your growing and often unpredictable storage requirements. There is no limit to the amount of data you can store in the service.
Simple– Amazon Glacier allows you to offload the administrative burdens of operating and scaling archival storage to AWS, and makes long term data archiving especially simple. You no longer need to worry about capacity planning, hardware provisioning, data replication, hardware failure detection and repair, or time-consuming hardware migrations.
Designed for use with other Amazon Web Services – You can use AWS Import/Export to accelerate moving large amounts of data into Amazon Glacier using portable storage devices for transport. In the coming months, Amazon Simple Storage Service (Amazon S3) plans to introduce an option that will allow you to seamlessly move data between Amazon S3 and Amazon Glacier using data lifecycle policies.

Amazon Glacier is currently available in the US-East (N. Virginia), US-West (N. California), US-West (Oregon), EU-West (Ireland), and Asia Pacific (Japan) Regions.

A few clicks in the AWS Management Console are all it takes to setup Amazon Glacier. You can learn more by visiting the Amazon Glacier detail page, reading Jeff Barrs blog post, or joining our September 19th webinar.
Sincerely,
The Amazon Web Services Team

What is AWS Glacier?

Glacier is low-cost for lower performance (e.g. access time) storage suited to data applications including archiving, inactive or idle data that you are not in a hurry to retrieve. Pay as you go pricing that can be as low as $0.01 USD per GByte per month (and other optional fees may apply, see here) depending on availability zone. Availability zone or regions include US West coast (Oregon or Northern California), US East Coast (Northern Virginia), Europe (Ireland) and Asia (Tokyo).

Now what is understood should have to be discussed, however just to be safe, pity the fool who complains about signing up for AWS Glacier due to its penny per month per GByte cost and it being too slow for their iTunes or videos as you know its going to happen. Likewise, you know that some creative vendor or their surrogate is going to try to show a miss-match of AWS Glacier vs. their faster service that caters to a different usage model; it is just a matter of time.

Lets be clear, Glacier is designed for low-cost, high-capacity, slow access of infrequently accessed data such as an archive or other items. This means that you will be more than disappointed if you try to stream a video, or access a document or photo from Glacier as you would from S3 or EBS or any other cloud service. The reason being is that Glacier is designed with the premise of low-cost, high-capacity, high availability at the cost of slow access time or performance. How slow? AWS states that you may have to wait several hours to reach your data when needed, however that is the tradeoff. If you need faster access, pay more or find a different class and tier of storage service to meet that need, perhaps for those with the real need for speed, AWS SSD capabilities ;).

Here is a link to a good post over at Planforcloud.com comparing Glacier vs. S3, which is like comparing apples and oranges; however, it helps to put things into context.

In terms of functionality, Glacier security includes secure socket layer (SSL), advanced encryption standard (AES) 256 (256-bit encryption keys) data at rest encryption along with AWS identify and access management (IAM) policies.

Persistent storage designed for 99.999999999% durability with data automatically placed in different facilities on multiple devices for redundancy when data is ingested or uploaded. Self-healing is accomplished with automatic background data integrity checks and repair.

Scale and flexibility are bound by the size of your budget or credit card spending limit along with what availability zones and other options you choose. Integration with other AWS services including Import/Export where you can ship large amounts of data to Amazon using different media and mediums. Note that AWS has also made a statement of direction (SOD) that S3 will be enhanced to seamless move data in and out of Glacier using data policies.

Part of stretching budgets for organizations of all size is to avoid treating all data and applications the same (key theme of data protection modernization). This means classifying and addressing how and where different applications and data are placed on various types of servers, storage along with revisiting modernizing data protection.

While the low-cost of Amazon Glacier is an attention getter, I am looking for more than just the lowest cost, which means I am also looking for reliability, security among other things to gain and keep confidence in my cloud storage services providers. As an example, a few years ago I switched from one cloud backup provider to another not based on cost, rather functionality and ability to leverage the service more extensively. In fact, I could switch back to the other provider and save money on the monthly bills; however I would end up paying more in lost time, productivity and other costs.

What do I see as the barrier to AWS Glacier adoption?

Simple, getting vendors and other service providers to enhance their products or services to leverage the new AWS Glacier storage category. This means backup/restore, BC and DR vendors ranging from Amazon (e.g. releasing S3 to Glacier automated policy based migration), Commvault, Dell (via their acquisitions of Appassure and Quest), EMC (Avamar, Networker and other tools), HP, IBM/Tivoli, Jungledisk/Rackspace, NetApp, Symantec and others, not to mention cloud gateway providers will need to add support for this new capabilities, along with those from other providers.

As an Amazon EC2 and S3 customer, it is great to see Amazon continue to expand their cloud compute, storage, networking and application service offerings. I look forward to actually trying out Amazon Glacier for storing encrypted archive or inactive data to compliment what I am doing. Since I am not using the Amazon Cloud Storage Gateway, I am looking into how I can use Rackspace Jungledisk to manage an Amazon Glacier repository similar to how it manages my S3 stores.

As of now, it looks like I will have to wait for either Jungledisk adds native support as they do today for managing my S3 storage pool today, or, the automated policy based movement between S3 and Glacier is transparently enabled.

Ok, nuff said for now

IBM buys flash solid state device (SSD) industry veteran TMS

How much flash (or DRAM) based Solid State Device (SSD) do you want or need?

IBM recently took a flash step announcing it wants and needs more SSD capabilities in different packaging and functionality capabilities to meet the demands and opportunities of customers, business partners and prospects by acquiring Texas Memory Systems (TMS).

IBM buys SSD flash vendor TMS

Unlike most of the current generation of SSD vendors besides those actually making the dies (chips or semiconductors) or SSD drives that are startups or relatively new, TMS is the industry veteran. Where most of the current SSD vendors experiences (as companies) is measured in months or at best years, TMS has seen several generations and SSD adoption cycles during its multi-decade existence.

What this means is that TMS has been around during past dynamic random access memory (DRAM) based SSD cycles or eras, as well as being an early adopter and player in the current nand flash SSD era or cycle.

Granted, some in the industry do not consider the previous DRAM based generation of products as being SSD, and vice versa, some DRAM era SSD aficionados do not consider nand flash as being real SSD. Needless to say that there are many faces or facets to SSD ranging in media (DRAM, and nand flash among others) along with packaging for different use cases and functionality.

IBM along with some other vendors recognize that the best type of IO is the one that you do not have to do. However reality is that some type of Input Output (IO) operations need to be done with computer systems. Hence the second best type of IO is the one that can be done with the least impact to applications in a cost-effective way to meet specific service level objectives (SLO) requirements. This includes leveraging main memory or DRAM as cache or buffers along with server-based PCIe SSD flash cards as cache or target devices, along with internal SSD drives, as well as external SSD drives and SSD drives and flash cards in traditional storage systems or appliances as well as purpose-built SSD storage systems.

While TMS does not build the real nand flash single level cell (SLC) or multi-level cell (MLC) SSD drives (like those built by Intel, Micron, Samsung, SANdisk, Seagate, STEC and Western Digital (WD) among others), TMS does incorporate nand flash chips or components that are also used by others who also make nand flash PCIe cards and storage systems.

IMHO this is a good move for both TMS and IBM, both of whom have been StorageIO clients in the past (here, here and here) that was a disclosure btw ;) as it gives TMS, their partners and customers a clear path and large organization able to invest in the technologies and solutions on a go forward basis. In other words, TMS who had looked to be bought gets certainty about their future as do they clients.

IBM who has used SSD based components such as PCIe flash SSD cards and SSD based drives from various suppliers gets a PCIe SSD card of their own, along with purpose-built mature SSD storage systems that have lineages to both DRAM and nand flash-based experiences. Thus IBM controls some of their own SSD intellectual property (e.g. IP) for PCIe cards that can go in theory into their servers, as well as storage systems and appliances that use Intel based (e.g. xSeries from IBM) and IBM Power processor based servers as a platform such. For example DS8000 (Power processor), and Intel based XIV, SONAS, V7000, SVC, ProtecTier and Pursystems (some are Power based).

In addition IBM also gets a field proven purpose-built all SSD storage system to compete with those from startups (Kaminario, Purestorage, Solidfire, Violin and Whiptail among others), as well as those being announced from competitors such as EMC (e.g. project X and project thunder) in addition to SSD drives that can go into servers and storage systems.

The question should not be if SSD is in your future, rather where will you be using it, in the server or a storage system, as a cache or a target, as a PCIe target or cache card or as a drive or as a storage system. This also means the question of how much SSD do you need along with what type (flash or DRAM), for what applications and how configured among other topics.

What this means is that there are many locations and places where SSD fits, one type of product or model does not fit or meet all requirements and thus IBM with their acquisition of TMS, along with presumed partnership with other SSD based components will be able to offer a diverse SSD portfolio.

The industry trend is for vendors such as Cisco, Dell, EMC, IBM, HP, NetApp, Oracle and others all of whom are either physical server and storage vendors, or in the case of EMC, virtual servers partnered with Cisco (vBlock and VCE) and Lenovo for physical servers.

Thus it only makes sense for those vendors to offer diverse SSD product and solution offerings to meet different customer and application needs vs. having a single solution that users adapt to. In other words, if all you have is a hammer, everything needs to look like a nail, however if you have a tool box of various technologies, then it comes down to being able to leverage including articulating what to use when, where, why and how for different situations.

I think this is a good move for both IBM and TMS. Now lets watch how IBM and TMS can go beyond the press release, slide decks and webex briefings covering why it is a good move to justify their acquisition and plans, moving forward and to see the results of what is actually accomplished near and long-term.

Read added industry trends and perspective commentary about IBM buying TMS here and here, as well as check out these related posts and content:

Open Data Center Alliance (ODCA) publishes two new cloud usage models

The Open Data Center Alliance (ODCA) has announced and published more documents for data center customers of cloud usage. These new cloud usage models for to address customer demands for interoperability of various clouds and services before for Infrastructure as a Service (IaaS) among other topics which are now joined by the new Software as a Service (SaaS), Platform as a Service (PaaS) and foundational document for cloud interoperability.

Unlike most industry trade groups or alliances that are vendor driven or centric, ODCA is consortium of global IT leaders (e.g. customers) that is vendor independent and comprises as 12 member steering committee from member companies (e.g. customers), learn more about ODCA here.

Disclosure note, StorageIO is an ODCA member, visit here to become an ODCA member.

From the ODCA announcement of the new documents:

The documents detail expectations for market delivery to the organizations mission of open, industry standard cloud solution adoption, and discussions have already begun with providers to help accelerate delivery of solutions based on these new requirements. This suite of requirements was joined by a Best Practices document from National Australia Bank (NAB) outlining carbon footprint reductions in cloud computing. NAB’s paper illustrates their leadership in innovative methods to report carbon emissions in the cloud and aligns their best practices to underlying Alliance requirements. All of these documents are available in the ODCA Documents Library.

The PaaS interoperability usage model outlines requirements for rapid application deployment, application scalability, application migration and business continuity. The SaaS interoperability usage model makes applications available on demand, and encourages consistent mechanisms, enabling cloud subscribers to efficiently consume SaaS via standard interactions. In concert with these usage models, the Alliance published the ODCA Guide to Interoperability, which describes proposed requirements for interoperability, portability and interconnectivity. The documents are designed to ensure that companies are able to move workloads across clouds.

It is great to see IT customer driven or centric groups step and actually deliver content and material to help their peers, or in some cases competitors that compliments information provided by vendors and vendor driven trade groups.

As with technologies, tools and services that often are seen as competitive, a mistake would be viewing ODCA as or in competition with other industry trade groups and organizations or vise versa. Rather, IT organizations and vendors can and should leverage the different content from the various sources. This is an opportunity for example vendors to learn more about what the customers are thinking or concerned about as opposed to telling IT organizations what to be looking at and vise versa.

Granted some marketing organizations or even trade groups may not like that and view groups such as ODCA as giving away control of who decides what is best for them. Smart vendors, vars, business partners, consultants and advisors are and will leverage material and resources such as ODCA, and likewise, groups like ODCA are open to including a diverse membership unlike some pay to play industry vendor centric trade groups. If you are a vendor, var or business partner, don’t look at ODCA as a threat, instead, explore how your customers or prospects may be involved with, or using ODCA material and leverage that as a differentiator between you and your competitor.

Likewise don’t be scared of vendor centric industry trade groups, alliances or consortiums, even the pay to play ones can have some value, although some have more value than others. For example from a storage and storage networking perspective, there are the Storage Networking Industry Association (SNIA) along with their various groups focused on Green and Energy along with Cloud Data Management Initiative (CDMI) related topics among others. There is also the SCSI Trade Association (STA) along with the Open Virtualization Alliance (OVA) not to mention the Open Fabric Alliance (OVA), Open Networking Foundation (ONF) and Computer Measurement Group (CMG) among many others that do good work and offer value with diverse content and offerings, some of which are free including to non members.

Learn more about the ODCA here, along with access various documents including usage models in the ODCA document library here.

While you are at, why not join StorageIO and other members by signing up to become a part of the ODCA here.

Ok, nuff said for now.
