Part IV: PureSystems, something old, something new, something from big blue

This is the fourth in a five-part series around the recent IBM PureSystems announcements. You can view the earlier post here, and the next post here.

So what does this mean for IBM Business Partners (BPs) and ISVs?
What could very well differentiate IBM PureSystems from those of other competitors is to take what their partner NetApp has done with FlexPods combing third-party applications from Microsoft and SAP among others and take it to the next level. Similar to what helped make EMC Centera a success (or at least sell a lot of them) was inclusion and leveraging third-party ISVs and BPs to add value. Compared to other vendors with object based or content accessible storage (CAS) or online archive platforms that focused on the technology feature, function speeds and feeds, EMC realized the key was getting ISVs to support so that BPs and their own direct sales force could sell the solution.

With PureSystems, IBM is revisiting what they have done in the past which if offer bundled solutions providing incentives for ISVs to support and BPs to sell the IBM brand solution. EMC took an early step with including VMware with their Vblock combing server, storage, networking and software with NetApp taking the next step adding SAP, Microsoft and other applications. Dell, HP, Oracle and others are following suit so it only makes sense that IBM returns to its roots leveraging its DNA to reach out and get their ISVs who are now, have been in the past, or are new opportunities to be on board.

IBM is throwing its resources including their innovation centers for training around the world where business partners can get the knowledge and technical support they need. In other words, workshops or seminars on how to sell deploy and setting up of these systems, application and customer testing or proof of concepts and things one would expect out of IBM for such an initiative. In addition to technology and sales training along with marketing support, IBM is making their financing capabilities available to help customers as well as offer incentives to their business partners to simplify acquisitions.

So what buzzword bingo topics and themes did IBM address with this announcement:
IBM did a fantastic job in terms of knocking the ball out of the park with this announcement pertaining buzzword bingo and deserves an atta boy or atta girl!

So what about how this will affect sales of Bladecenters or other systems?
If all IBM and their BPs do are, encroach on existing systems sales to circle the wagons and protect the installed base, which would be one thing. However if IBM and their BPs can use the new packaging and model approach to reestablish customers and partnerships, or open and expand into new adjacent markets, then the net differences should be more Bladecenters (excuse me, PureFlex) being sold.

So what will this cost?
IBM is citing entry PureSystems Express models starting at around $100,000 USD for base systems with others starting at around $200,000 and $300,000 expandable into larger configurations and budgets. Note that like airlines that advertise a low airfare and then you get to pay extra for peanuts, drinks, extra bag space, changes to reservations and so forth, look at these and related systems not just for the first starting price, also for expansion costs over different time periods. Contact IBM, your BP or ISV to find out what one of these systems will do for and cost you.

So what about VARs and IBM business partners (BPs)?
This could be a boon for those BPs and ISVs that had previously sold their software solutions bundled with IBM hardware platforms who were being challenged by other converged solution stacks or were being forced to unbundled. This will also allow those business partners to compete on par with other converged solutions or continue selling the pieces of what they are familiar with however under a new umbrellas. Of course, pricing will be a focus and concern for some who will want to see what added value exists vs. acquiring the various components. This also means that IBM will have to make incentives available for their partners to make a living while also allowing their customers to afford solutions and maximize their return on innovation (the new ROI) and enablement.

Part V: PureSystems, something old, something new, something from big blue

This is the fifth in a five-part series around the recent IBM PureSystems announcements. You can view the earlier post here.

So what about vendor or technology lock in?
So who is responsible for vendor or technology lock in? When I was working in IT organizations, (e.g. what vendors call the customer) the thinking was vendors are responsible for lock in. Later when I worked for different vendors (manufactures and VARs) the thinking was lock in is what was caused by the competition. More recently I’m of the mind set that vendor lock in is a shared responsibility issue and topic. I’m sure some marketing wiz or sales type will be happy to explain the subtle differences of how their solution does not cause lock in.

Vendor lock in can be a shared responsibility. Generally speaking, lock in, stickiness and account control are essentially the same, or at least strive to get similar results. For example, vendor lock in too some has a negative stigma. However vendor stickiness may be a new term, perhaps even sounding cool thus it is not a concern. Remember the Mary Poppins song a spoon full of sugar makes the medicine go down? In other words, sometimes changing and using a different term such as sticky vs. vendor lock in helps make the situation taste better.

So what should you do?
Take a closer look if you are considering converged infrastructures, cloud or data centers in a box, turnkey application or information services deployment platforms. Likewise, if you are looking at specific technologies such as those from Cisco UCS, Dell vStart, EMC Vblock (or via VCE), HP, NetApp FlexPod or Oracle (ExaLogic, ExaData, etc) among others, also check out the IBM PureSystems (Flex and PureApplication). Compare and contrast these converged solutions with your traditional procurement and deployment modes including cost of acquiring hardware, software, ongoing maintenance or service fees along with value or benefit of bundled tools. There may be a higher cost for converged systems in some scenarios, however compare on the value and benefit derived vs. doing the integration yourself.

Compare and contrast how converged solutions enable, however also consider what constraints exists in terms of flexibility to reconfigure in the future or make other changes. For example as part of integration, does a solution take a lowest common denominator approach to software and firmware revisions for compatibility that may lag behind what you can apply to standalone components. Also, compare and contrast various reference architectures with different solution bundles or packages.

Most importantly compare and evaluate the solutions on their ability to meet and exceed your base requirements while adding value and enabling return on innovation while also being cost-effective. Do not be scared of these bundled solutions; however do your homework to make informed decisions including overcoming any concerns of lock in or future costs and fees. While these types of solutions are cool or interesting from a technology perspective and can streamline acquisition and deployment, make sure that there is a business benefit that can be addressed as well as enablement of new capabilities.

So what does this all mean?
Congratulations to IBM with their PureSystems for leveraging their DNA and roots bundling what had been unbundled before cloud and stacks were popular and trendy. IBM has done a good job of talking vision and strategy along lines of converged and dynamic, elastic and smart, clouds and other themes for past couple of years while selling the pieces as parts of solutions or ala carte or packaged by their ISVs and business partners.

What will be interesting to see is if bladecenter customers shift to buying PureFlex, which should be an immediate boost to give proof points of adoption, while essentially up selling what was previously available. However, more interesting will be to see if net overall new customers and footprints are sold as opposed to simply selling a newer and enhanced version of previous components.

In other words will IBM be able to keep up their focus and execution where they have sold the previous available components, while also holding onto current ISV and BP footprint sales and perhaps enabling those partners to recapture some hardware and solution sales that had been unbundled (e.g. ISV software sold separate of IBM platforms) and move into new adjacent markets.

Part III: PureSystems, something old, something new, something from big blue

This is the third in a five-part series around the recent IBM PureSystems announcements. You can view the earlier post here, and the next post here.

So what about the IBM Virtual Appliance Factory?
Where PureFlex and PureApplication (PureSystems) are the platforms or vehicles for enabling your journey to efficient and effective information services delivery, and PureSystem centre (or center for those of you in the US) is the portal or information center, the IBM Virtual Appliance Factory (VAF) is a collection of tools, technologies, processes and methodologies. The VAF helps developers or ISVs to prepackage applications or solutions for deployment into Kernel Virtual Machine (KVM) on Intel and IBM PowerVM virtualized environments that are also supported by PureFlex and PureApplication systems.

VAF technologies include Distributed Management Task Force (DMTF) Open Virtual Alliance (OVA) Open Virtualization Format (OVF) along with other tools for combing operating systems (OS), middleware and solution software into a delivery package or a virtual appliance that can be deployed into cloud and virtualized environments. Benefits include reducing complexity of working logical partions (LPAR) and VM configuration, abstraction and portability for deployment or movement from private to public environments. Net result should be less complexity lowering costs while reducing mean time to install and deploy. Here is a link to learn more about VAF and its capabilities and how to get started.

So what does cloud ready mean?
IBM is touting cloud ready capability in the context of rapid out of the box, ease of deployment and use as well as easy to acquire. This is in line with what others are doing with converged server, storage, networking, hardware, software and hypervisor solutions. IBM is also touting that they are using the same public available products as what they use in their own public services SmartCloud offerings.

So what is scale in vs. scale up, scale out or scale within?
Traditional thinking is that scaling refers to increasing capacity. Scaling also means increasing performance, availability, functionality with stability. Scaling with stability means that as performance, availability, capacity or other features are increased problems are not introduced or complexity is not increased. For example, scaling with stability for performance should not result in loss of availability or capacity, capacity increase should not be at the cost of performance or availability, should not cost performance or capacity and management tools should work for you, instead of you working for them.

Scaling up and scaling out have been used to describe scaling performance, availability, capacity and other attributes beyond the limits of a single system, box or cabinet. For example clustered, cloud, grid and other approaches refer to scaling out or horizontally across different physical resources. Scaling up or scaling vertically means scaling within in a system using faster, denser technologies doing more in the same footprint. HDS announced a while back what they refer to 3D scaling which embraces the above notions of scaling up, out and within across different dimensions. IBM is building on that by emphasizing scaling leveraging faster, denser components such as Power7 and Intel processors to scale within the box or system or node, which can also be scaled out using enhanced networking from IBM and their partners.

So what about backup/restore, BC, DR and general data protection?
I would expect IBM to step up and talk about how they can leverage their data protection and associated management toolsets, technologies and products. IBM has the components (hardware, software) already for backup/restore, BC, DR, data protection and security along with associated service offerings. One would expect IBM to not only come out with a backup, restore, BC, DR and archiving solution or version, as well as ones for archiving or data preservation, compliance appliance variants as well as related themes. We know that IBM has the pieces, people, process and practices, let us see if IBM has learned from their competitors who may have missed data protection messaging opportunities. Sometimes what is assumed to be understood does not get discussed, however often what is assumed and is not understood should be discussed, hence, let us see if IBM does more than say oh yes, we have those capabilities and products too.

So what do these have compared to others who are doing similar things?
Different vendors have taken various approaches for bringing converged products or solutions to the market place. Not surprising, storage centric vendors EMC and NetApp have partnered with Cisco for servers (compute). Where Cisco was known for networking having more recently moved into compute servers, EMC and NetApp are known for storage and moving into converged space with servers. Since EMC and NetApp often compete with storage solutions offerings from traditional server vendors Dell, HP, IBM and Oracle among others, and now Cisco is also competing with those same server vendors it has previously partnered with for networking thus it makes sense for Cisco, EMC and NetApp to partner.

While EMC owns a large share of VMware, they do also support Microsoft and other partners including Citrix. NetApp followed EMC into the converged space partnering with Cisco for compute and networking adding their own storage along with supporting hypervisors from Citrix, Microsoft and VMware along with third-party ISVs including Microsoft and SAP among others. Dell has evolved from reference architectures to products called vStart that leverage their own technologies along with those of partners.

A challenge for Dell however is that vStart sounds more like a service offering as opposed to a product that they or their VARs and business partners can sell and add value around. HP is also in the converged game as is Oracle among others. With PureSystems IBM is building on what their competitors and in some cases partners are doing by adding and messaging more around the many ISVs and applications that are part of the PureSystems initiative. Rest assured, there is more to PureSystems than simply some new marketing, press releases, videos and talking about partners and ISVs. The following table provides a basic high level comparison of what different vendors are doing or working towards and is not intended to be a comprehensive review.

Who	What	Server	Storage	Network	Software	Other comments
Cisco	UCS	Cisco	Partner	Cisco	Cisco and Partners	Various hypervisors and OS
Dell	vStart	Dell	Dell	Dell and Partners	Dell and partners	Various hypervisors, OS and bundles
EMC VCE	Vblock VSPEX	Cisco	EMC	Cisco and partners	EMC, Cisco and partners	Various hypervisors, OS and bundles, VSPEX adds more partner solution bundles
HP	Converged	HP	HP	HP and partners	HP and partners	Various hypervisors, OS and bundles
IBM	PureFlex	IBM	IBM	IBM and partners	IBM and partners	Various hypervisors, OS and bundles adding more ISV partners
NetApp	FlexPod	Cisco	NetApp	Cisco and partners	NetApp, Cisco and partners	Various hypervisors, OS and bundles for SAP, Microsoft among others
Oracle	ExaLogic (Exadata database)	Oracle	Oracle	Partners	Oracle and partners	Various Oracle software tools and technologies

So what took IBM so long compared to others?
Good question, what is the saying? Rome was not built-in a day!

Part II: PureSystems, something old, something new, something from big blue

This is the second in a five-part series around the recent IBM PureSystems announcements. You can view the earlier post here, and the next post here.

So what are the speeds and feeds of a PureFlex system?
The components that make up the PureFlex line include:

IBM management node (server with management software tools).
10Gb Ethernet (LAN) switch, adapters and associated cabling.
IBM V7000 virtual storage (also see here and here).
Dual 8GFC (8Gb Fibre Channel) SAN switches and adapters.
Servers with either x86 xSeries using for example Intel Sandy Bridge EP 2.6 GHz 8 core processors, or IBMs Power7 based pSeries for AIX. Note that IBM with their blade center systems (now rebadged as part of being PureSystems) support various IO and networking interfaces include SAS, Ethernet, Fibre Channel (FC), Fibre Channel over Ethernet (FCoE), and InfiniBand using adapters and switches from various partners.
Virtual machine (VM) hypervisors such as Microsoft Hyper V and VMware vSphere/ESX among others. In addition to x86 based hypervisors or kernel virtual machines (KVM), IBM also supports its own virtual technology found in Power7 based systems. Check IBM support matrix for specific configurations and current offerings.
Optional middleware such as IBM WebSphere.

Read more speeds and feeds at the various IBM sites including on Tony Pearson’s blog site.

So what is IBM PureApplication System?
This builds off and on PureFlex systems as a foundation for deploying various software stacks to deliver traditional IT applications or cloud Platform as a Service (PaaS) or Software as a Service (SaaS) and Application as a Service (AaaS) models. For example cloud or web stacks, java, database, analytics or other applications with buzzwords of elastic, scalable, repeatable, self-service, rapid provisioning, resilient, multi tenant and secure among others. Note that if are playing or into Buzzword bingo, go ahead and say Bingo when you are ready as IBM has a winner in this category.

So what is the difference between PureFlex and PureApplication systems?
PureApplication systems leverage PureFlex technologies adding extra tools and functionality for cloud like application functionality delivery.

So what is IBM PureSystems Centre?
It is a portal or central place where IBM and their business partner solutions pertaining to PureApplication and PureFlex systems can be accessed for including information for first installation support along with maintenance and upgrades. At launch, IBM is touting more than 150 solutions or applications that are available or qualified for deployment on PureApplication and PureFlex systems. In addition, IBM Patterns (aka templates) can also be accessed via this venue. Examples of application or independent software vendor (ISV) developed solutions for banking, education, financial, government, healthcare and insurance can be found at the PureSystems Centre portal (here, here and here).

So what part of this is a service and what is a product?
Other than the PureSystem center, which is a web portal for accessing information and technologies, PureFlex and PureApplication along with Virtual Appliance Factory are products or solutions that can be bought from IBM or their business partners. In addition, IBM business partners or third parties can also use these solutions housed in their own, a customer, or third-party facility for delivering managed service provided (MSP) capabilities, along with other PaaS and SaaS or AaaS type functionalities. In other words, these solutions can be bought or leased by IT and other organizations for their own use in a traditional IT deployment model, private, hybrid or public cloud model.

Another option is for service providers to acquire these solutions for use in developing and delivering their own public and private or hybrid services. IBM is providing the hard product (hardware and software) that enables your return on innovation (the new ROI) to create and deliver your own soft product (services and experiences) consumed by those who use those capabilities. In addition to traditional financial quantitative return on investment (traditional ROI) and total cost of ownership (TCO), the new ROI complements those by adding a qualitative aspect. Your return on innovation will be dependent on what you are capable of doing that enables your customers or clients to be productive or creative. For example enabling your customers or clients to boost productivity, remove complexity and cost while maintaining or enhancing Quality of Service (QoS), service level objectives (SLOs) and service level agreements (SLAs) in addition to supporting growth by using a given set of hard products. Thus, your soft product is a function of your return on innovation and vise versa.

Note that in this context, not to be confused with hardware and software, hard product are those technologies including hardware, software and services that are obtained and deployed as a soft product. A soft product in this context does not refer to software, rather the combination of hard products plus your own developed or separately obtained software and tools along with best practices and usage models. Thus, two organizations can use the same hard products and deliver separate soft products with different attributes and characteristics including cost, flexibility and customer experience.

So what is a Pattern of Expertise?
Combines operational know how experience and knowledge about common infrastructure resource management (IRM), data center infrastructure management (DCIM) and other commonly repeatable related process, practices and workflows including provisioning. Common patterns of activity and expertise for routine or other time-consuming tasks, which some might refer to as templates or workflows enable policy driven based automation. For example, IBM cites recurring time-consuming tasks that lend themselves to being automated such as provisioning, configuration, and upgrades and associated IRM, DCIM and data protection, storage and application management activities. Automation software tools are included as part of the PureSystems with patterns being downloadable as packages for common tasks and applications found at the IBM PureSystem center.

At announcement, there are three types or categories of patterns:

IBM patterns: Factory created and supplied with the systems based on experiences IBM has derived from various managers, engineers and technologist for automating common tasks including configuration, deployment and application upgrades and maintenance. The aim is to cut the amount of time and intervention for deployment of applications and other common functions enabling IT staff to be more productive and address other needs.
ISV patterns: These leverage experience and knowledge from ISVs partnered with IBM, which at time of launch numbers over 125 vendors offering certified PureSystems Ready applications. The benefit and objective are to cut the time and complexity associated with procuring (e.g. purchasing), deploying and managing third-party ISV software. Downloadable patterns packages can be found at the IBM PureSystem center.
Customer patterns: Enables customers to collect and package their own knowledge, processes, rules, policies and best practices into patterns for automation. In addition to collecting knowledge for acquisition, configuration, day to day management and troubleshooting, these patterns can facility automation of tasks to ease on boarding of new staff employees or contractors. In addition, these patterns or templates capture workflows for automation enabling shorter deployment times of systems and applications into locations where skill sets do not exist.

Here is a link to some additional information about patterns on the IBM developerWorks site.

Part I: PureSystems, something old, something new, something from big blue

This is the first in a five-part series around the recent IBM PureSystems announcements. You can view the next post here.

For a certain generation of IBM faithful or followers the recently announced PureFlex and PureApplication systems might give a sense of DejaVu perhaps even causing some to wonder if they just woke up from a long Rip Van Winkle type nap.

Yet for another generation who may not yet be future IBM followers, fans, partners or customers, there could be a sense of something new and revolutionary with the PureFlex and PureApplication systems (twitter @ibmpuresystems).

In between those two groups, exist others who are either scratching their heads or reinvigorated with enthusiasm to get out and be able to discuss opportunities around little data (traditional and transactional) and big data, servers, virtualized, converged infrastructure, dynamic data centers, private clouds, ITaaS, SaaS and AaaS, PaaS, IaaS and other related themes or buzzword bingo topics.

Let us dig a little deeper and look at some So What types of questions and industry trends perspectives comments around what IBM has announced.

So what did IBM announce?
IBM announced PureSystems including:

PureFlex systems, products and technologies
PureApplication systems
PureSystems Centre

You can think of IBM PureSystems and Flex Systems Products and technology as a:

Private cloud or turnkey solution bundle solution
Platform deploying public or hybrid clouds
Data center in a box or converged and dynamic system
ITaaS or SaaS/AaaS or PaaS or IaaS or Cloud in a box
Rackem stack and package them type solution

So what is an IBM PureFlex System and what is IBM using?
It is a factory integrated data and compute infrastructure in a cabinet combing cloud, virtualization, servers, data and storage networking capabilities. The IBM PureFlex system is comprised of various IBM and products and technologies (hardware, software and services) optimized with management across physical and virtual resources (servers, storage (V7000), networking, operating systems, hypervisors and tools).

PureFlex includes automation and optimization technologies along with what IBM is referring to as patterns of expertise or what you might relate to as templates. Support for various hypervisors and management integration along with application and operating system support by leveraging IBM xSeries (x86 such as Intel) and pSeries (Power7) based processors for compute. Storage is the IBM V7000 (here and here) with networking and connectivity via IBM and their partners. The solution is capable of supporting traditional, virtual and cloud deployment models as well as platform for deploying Infrastructure as a Service (IaaS) on a public, managed service provider (MSP), hosting or private basis.

Is 14.4TBytes of data storage for $52,503 a good deal? It depends!

A news story about the school board in Marshall Missouri approving data storage plans in addition to getting good news on health insurance rates just came into my in box.

I do not live in or anywhere near Marshall Missouri as I live about 420 miles north in the Stillwater Minnesota area.

What caught my eye about the story is the dollar amount ($52,503) and capacity amount (14.4TByte) for the new Marshall school district data storage solution to replace their old, almost full 4.8TByte system.

That prompted me to wonder, if the school district are getting a really good deal (if so congratulations), paying too much, or if about right.

Not knowing what type of storage system they are getting, it is difficult to know what type of value the Marshall School district is getting with their new solution. For example, what type of performance and availability in addition to capacity? What type of system and features such as snapshots, replication, data footprint reduction aka DFR capabilities (archive, compression, dedupe, thin provisioning), backup, cloud access, redundancy for availability, application agents or integration, virtualization support, tiering. Or if the 14.4TByte is total (raw) or usable storage capacity or if it includes two storage systems for replication. Or what type of drives (SSD, fast SAS HDD or high-capacity SAS or SATA HDDs), block (iSCSI, SAS or FC) or NAS (CIFS and NFS) or unified, management software and reporting tools among capabilities not to mention service and warranty.

Sure there are less expensive solutions that might work, however since I do not know what their needs and wants are, saying they paid too much would not be responsible. Likewise, not knowing their needs vs. wants, requirements, growth and application concerns, given that there are solutions that cost a lot more with extensive capabilities, saying that they got the deal of the century would also not be fair. Maybe somewhere down the road we will hear some vendor and VAR make a press release announcement about their win in taking out a competitor from the Marshall school district, or perhaps that they upgraded a system they previously sold so we can all learn more.

With school districts across the country trying to stretch their budgets to go further while supporting growth, it would be interesting to hear more about what type of value the Marshall school district is getting from their new storage solution. Likewise, it would also be interesting to hear what alternatives they looked at that were more expensive, as well as cheaper however with less functionality. I’m guessing some of the cloud crowd cheerleaders will also want to know why the school district is going the route they are vs. going to the cloud.

IMHO value is not the same thing as less or lower cost or cheaper, instead its the benefit derived vs. what you pay. This means that something might cost more than something cheaper, however if I get more benefit from what might be more expensive, then it has more value.

If you are a school district of similar size, what criteria or requirements would you want as opposed to need, and then what would you do or have you done?

What if you are a commercial or SMB environment, again not knowing the feature functionality benefit being obtained, what requirements would you have including want to have (e.g. nice to have) vs. must or have to have (e.g. what you are willing to pay more for), what would you do or have done?

How about if you were a cloud or managed service provider (MSP) or a VAR representing one of the many services, what would your pitch and approach be beyond simply competing on a cost per TByte basis?

Or if you are a vendor or VAR facing a similar opportunity, again not knowing the requirements, what would you recommend a school district or SMB environment to do, why and how to cost justify it?

What this all means to me is the importance of looking beyond lowest cost, or cost per capacity (e.g. cost per GByte or TByte) also factoring in value, feature functionality benefit.

Ok, nuff said for now, I need to get my homework assignments done.

Why SSD based arrays and storage appliances can be a good idea (Part II)

This is the second of a two-part post about why storage arrays and appliances with SSD drives can be a good idea, here is link to the first post.

So again, why would putting drive form factors SSDs be a bad idea for existing storage systems, arrays and appliances?

Benefits of SSD drive in storage systems, arrays and appliances:

Familiarity with customers who buy and use these devices
Reduces time to market enabling customers to innovate via deployment
Establish comfort and confidence with SSD technology for customers
Investment protection of currently installed technology (hardware and software)
Interoperability with existing interfaces, infrastructure, tools and policies
Reliability, availability and serviceability (RAS) depending on vendor implementation
Features and functionality (replicate, snapshot, policy, tiering, application integration)
Known entity in terms of hardware, software, firmware and microcode (good or bad)
Share SSD technology across more servers or accessing applications
Good performance assuming no controller, hardware or software bottlenecks
Wear leveling and other SSD flash management if implemented
Can end performance bottlenecks if backend (drives) are a problem
Coexist or complemented with server-based SSD caching

Note, the mere presence of SSD drives in a storage system, array or appliance will not guarantee or enable the above items to be enabled, nor to their full potential. Different vendors and products will implement to various degrees of extensibility SSD drive support, so look beyond the check box of feature, functionality. Dig in and understand how extensive and robust the SSD implementation is to meet your specific requirements.

Caveats of SSD drives in storage systems, arrays and appliances:

May not use full performance potential of nand flash SLC technology
Latency can be an issue for those who need extreme speed or performance
May not be the most innovative newest technology on the block
Fun for startup vendors, marketers and their fans to poke fun at
Not all vendors add value or optimization for endurance of drive SSD
Seen as not being technology advanced vs. legacy or mature systems

Note that different vendors will have various performance characteristics, some good for IOPs, others for bandwidth or throughput while others for latency or capacity. Look at different products to see how they will vary to meet your particular needs.

Cost comparisons are tricky. SSD in HDD form factors certainly cost more than raw flash dies, however PCIe cards and FTL (flash translation layer) controllers also cost more than flash chips by themselves. In other words, apples to apples comparisons are needed. In the future, ideally the baseboard or motherboard vendors will revise the layout to support nand flash (or its replacement) with DRAM DIMM type modules along with associated FTL and BIOS to handle the flash program/erase cycles (P/E) and wear leveling management, something that DRAM does not have to encounter. While that provides great location or locality of reference (figure 1), it is also a more complex approach that takes time and industry cooperation.

Figure 1: Locality of reference for memory and storage

Certainly, for best performance, just like realty location matters and thus locality of reference comes into play. That is put the data as close to the server as possible, however when sharing is needed, then a different approach or a companion technique is required.

Here are some general thoughts about SSD:

Some customers and organizations get the value and role of SSD
Some see where SSD can replace HDD, others see where it compliments
Yet others are seeing the potential, however are moving cautiously
For many environments better than current performance is good enough
Environments with the need for speed need every bit of performance they can get
Storage systems and arrays or appliances continue to evolve including the media they use
Simply looking at how some storage arrays, systems and appliances have evolved, you can get an idea on how they might look in the future which could include not only SAS as a backend or target, also PCIe. After all, it was not that long ago where backend drive connections went from propriety to open parallel SCSI or SSA to Fibre Channel loop (or switched) to SAS.
Engineers and marketers tend to gravitate to newer products nand technology, which is good, as we need continued innovation on that front.
Customers and business people tend to gravitate towards deriving greatest value out of what is there for as long as possible.
Of course, both of the latter two points are not always the case and can be flip flopped.
Ultrahigh end environments and corner case applications will continue to push the limits and are target markets for some of the newer products and vendors.
Likewise, enterprise, mid market and other mainstream environments (outside of their corner case scenarios) will continue to push known technology to its limits as long as they can derive some business benefit value.

While not perfect, SSD in a HDD form factor with a SAS or SATA interface properly integrated by vendors into storage systems (or arrays or appliances) are a good fit for many environments today. Likewise, for some environments, new from the ground up SSD based solutions that leverage flash DIMM or daughter cards or PCIe flash cards are a fit. So to are PCIe flash cards either as a target, or as cache to complement storage system (arrays and appliances). Certainly, drive slots in arrays take up space for SSD, however so to does occupying PCIe space particularly in high density servers that require every available socket and slot for compute and DRAM memory. Thus, there are pros and cons, features and benefits of various approaches and which is best will depend on your needs and perhaps preferences, which may or may not be binary.

I agree that for some applications and solutions, non drive form factor SSD make sense while in others, compatibility has its benefits. Yet in other situations nand flash such as SLC combined with HDD and DRAM tightly integrated such as in my Momentus XT HHDD is good for laptops, however probably not a good fit for enterprise yet. Thus, SSD options and placements are not binary, of course, sometimes opinions and perspectives will be.

For some situations PCIe, based cards in servers or appliances make sense, either as a target or as cache. Likewise for other scenarios drive format SSD make sense in servers and storage systems, appliances, arrays or other solutions. Thus while all of those approaches are used for storing binary digital data, the solutions of what to use when and where often will not be binary, that is unless your approach is to use one tool or technique for everything.

Are social media and networking a waste of time?

Are social media and networking including twitter, blogs, google+ and linkedin among other venues and mediums a waste of time or only for those who have nothing else to do?

As with most things, the answer is it probably depends.

However IMHO the answer is NO, social media and networking when incorporated as a part of doing business is not a waste unless like anything else you let it become a waste of time.

I have chosen to leverage social media networking along with traditional mediums, venues, news letters, in person events, and other means of communicating, learning and doing business vs. ignoring it.

Does that I mean I jump on or join in every new social networking medium or venue? Nope, however I’m always watching to see where to invest time and effort and find the return or benefit.

Some observations about social media and networking include:

You get out of social media and networking what you put into it: When it comes to LinkedIn, Michael Naylor told me several years ago to get involved with and you will get out of what you put into LinkedIn (or other venues for that matter). Now about eight or nine years later, even despite the spam, I completely agree how true Mikes advise has been and remains.

Engagement, interaction, discussion (or debate) are all part of the discourse in and around social media and networking. Louis Gray who got me hooked on twitter and some other mediums years ago has a great blog post that unless you are engaging or interacting, you are not social networking. What that means is simply using social networking media and mediums as a broadcast or one way communication platform is just that, talking at vs. talking with or too people. Thus get out of your comfort zone, step out from behind your pulpit or podium and engage with audiences or participants vs. talking at them to get out of what you put into it.

Dont be afraid of joining different groups or venues, listen, lurk, observe, learn from others in the same or adjacent areas online, however also keep time in perspective to get other tasks completed. This also means you can build your own castle or venue for people to come to or you can do a hybrid including your own site(s) as well as taking discussions and conversations to where other audiences are.

Let me put this a different way, I like to fish and catch. Sometimes I know where the fish are based on experience and when they might bite, then there are other times when they move. This means knowing when and where to go to different locations to catch a fish or catch a conversation.

Building on the above, don’t be afraid to get involved or start a conversation.

Sure on some venues you will get spammed and a bunch of responses that you might not like particular if venturing out away from the safety of your own castle or site. However use those conversations and engagements to learn and interact, see what is on people’s minds or that they are interested in vs. what you want to tell them.

Where wasting time can come into play is trying to be part of every discussion, watching what everybody is doing or saying in all the various venues. For the trick has been to pick which venues are useful for where I want to invest time along with what I will get out of them in addition to using different tools to help find the applicable conversations and discussions. If you are not using things as basic as Google alerts you are probably spending too much time out looking for conversations or discussions, or, you are missing out on them altogether.

I have also noticed that there tends to be a correlation between those who are involved in one way communication and comment diminishing or dismissing social media and networking as a waste of time or not practical, hmm, go figure.

Otoh, I have also noticed those who tend to be involved in one way or non interactive discussions or that limit comments and discourse tend to also have lower numbers of followers, appear on fewer lists or get shared by others, hmm, go figure.

I have also noticed that some who do very well in cyberspace may not do as well in person and vise versa, however there are many who can do both. Likewise there are those who do well in columns that support interactive comments and those who do not.

Perhaps there is a hadoop big data analytics algorithm out there for someone who has lots of time to do some research on all of this?

In the meantime, for those interested, check out Johnny Bentwood (@JonnyBentwood) and some of the things he has done around analytics and social media and metrics if so interested.

What this all means is that to each their own, that is comfort zones. If your comfort zone and sphere of influence is in one way communication via print, online, video or what ever, then play to your strengths. Likewise, if yours is as a commentator or something else, go with it.

Leverage and get involved, don’t be scared, find your voice, engage, take part, however also be ready to be challenged while increasing your network of contacts, ability to learn and get out of what ever you put into it. Otherwise, stay in your comfort zone or within your sphere of influence.

As to if social media and networking are a waste of time and only for those who have nothing to do, well, if that is the case, last year was a banner year for me and my business. That is both in terms of activity, contacts, coverage, awards and accolades not to mention increasing discussions and experience in other areas as well as being involved in traditional media and venues or activities. I guess if that is the result of being involved or investing in social media and networking it is an honor to be among those who waste time and have nothing better to do.

Why do I take time out of my busy schedule to share this?

Simple, you get out of things what you put into it, and granted some will simply take advantage as opposed to contributing back, maybe they too will evolve to give back what they take out.

Feel free to engage or simply read and lurk, that option is all yours.

Ok, nuff said for now, have to get some other work projects done now.

Cheers

AWS (Amazon) storage gateway, first, second and third impressions

Amazon Web Services (AWS) today announced the beta of their new storage gateway functionality that enables access of Amazon S3 (Simple Storage Services) from your different applications using an appliance installed in your data center site. With this beta launch, Amazon joins other startup vendors who are providing standalone gateway appliance products (e.g. Nasuni etc) along with those who have disappeared from the market (e.g. Cirtas). In addition to gateway vendors, there are also those with cloud access added to their software tools such as (e.g. Jungle Disk that access both Rack space and Amazon S3 along with Commvault Simpana Cloud connector among others). There are also vendors that have joined cloud access gateways as part of their storage systems such as TwinStrata among others. Even EMC (and here) has gotten into the game adding qualified cloud access support to some of their products.

What is a cloud storage gateway?

Before going further, lets take a step back and address what for some may be a fundemental quesiton of what is a cloud storage gateway?

Cloud services such as storage are accessed via some type of network, either the public Internet or a private connection. The type of cloud service being accessed (figure 1) will decide what is needed. For example, some services can be accessed using a standard Web browser, while others must plug-in or add-on modules. Some cloud services may need downloading an application, agent, or other tool for accessing the cloud service or resources, while others give an on-site or on-premisess appliance or gateway.

Generic cloud access example via Cloud and Virtual Data Storage Networking (CRC Press)
Figure 1: Accessing and using clouds (From Cloud and Virtual Data Storage Networking (CRC Press))

Cloud access software and gateways or appliances are used for making cloud storage accessible to local applications. The gateways, as well as enabling cloud access, provide replication, snapshots, and other storage services functionality. Cloud access gateways or server-based software include tools from BAE, Citrix, Gladinet, Mezeo, Nasuni, Openstack, Twinstrata among others. In addition to cloud gateway appliances or cloud points of presence (cpops), access to public services is also supported via various software tools. Many data protection tools including backup/restore, archiving, replication, and other applications have added (or are planning to add) support for access to various public services such as Amazon, Goggle, Iron Mountain, Microsoft, Nirvanix, or Rack space among several others.

Some of the tools have added native support for one or more of the cloud services leveraging various applicaiotn programming interfaces (APIs), while other tools or applications rely on third-party access gateway appliances or a combination of native and appliances. Another option for accessing cloud resources is to use tools (Figure 2) supplied by the service provider, which may be their own, from a third-party partner, or open source, as well as using their APIs to customize your own tools.

Generic cloud access example via Cloud and Virtual Data Storage Networking (CRC Press)
Figure 2: Cloud access tools (From Cloud and Virtual Data Storage Networking (CRC Press))

For example, I can use my Amazon S3 or Rackspace storage accounts using their web and other provided tools for basic functionality. However, for doing backups and restores, I use the tools provided by the service provider, which then deal with two different cloud storage services. The tool presents an interface for defining what to back up, protect, and restore, as well as enabling shared (public or private) storage devices and network drives. In addition to providing an interface (Figure 2), the tool also speaks specific API and protocols of the different services, including PUT (create or update a container), POST (update header or Meta data), LIST (retrieve information), HEAD (metadata information access), GET (retrieve data from a container), and DELETE (remove container) functions. Note that the real behavior and API functionality will vary by service provider. The importance of mentioning the above example is that when you look at some cloud storage services providers, you will see mention of PUT, POST, LIST, HEAD, GET, and DELETE operations as well as services such as capacity and availability. Some services will include an unlimited number of operations, while others will have fees for doing updates, listing, or retrieving your data in addition to basic storage fees. By being aware of cloud primitive functions such as PUT or POST and GET or LIST, you can have a better idea of what they are used for as well as how they play into evaluating different services, pricing, and services plans.

Depending on the type of cloud service, various protocols or interfaces may be used, including iSCSI, NAS NFS, HTTP or HTTPs, FTP, REST, SOAP, and Bit Torrent, and APIs and PaaS mechanisms including .NET or SQL database commands, in addition to XM, JSON, or other formatted data. VMs can be moved to a cloud service using file transfer tools or upload capabilities of the provider. For example, a VM such as a VMDK or VHD is prepared locally in your environment and then uploaded to a cloud provider for execution. Cloud services may give an access program or utility that allows you to configure when, where, and how data will be protected, similar to other backup or archive tools.

Some traditional backup or archive tools have added direct or via third party support for accessing IaaS cloud storage services such as Amazon, Rack space, and others. Third-party access appliance or gateways enable existing tools to read and write data to a cloud environment by presenting a standard interface such as NAS (NFS and/or CIFS) or iSCSI (Block) that gets mapped to the back-end cloud service format. For example, if you subscribe to Amazon S3, storage is allocated as objects and various tools are used to use or utilize. The cloud access software or appliance understands how to communicate with the IaaS storage APIs and abstracts those from how they are used. Access software tools or gateways, in addition to translating or mapping between cloud APIs, formats your applications including security with encryption, bandwidth optimization, and data footprint reduction such as compression and de-duplication. Other functionality include reporting, management tools that support various interfaces, protocols and standards including SNMP or SNIA, Storage Management Initiative Specification (SMIS), and Cloud Data Management Initiative (CDMI).

First impression: Interesting, good move Amazon, I was ready to install and start testing it today

The good news here is that Amazon is taking steps to make it easier for your existing applications and IT environments to use and leverage clouds for private and hybrid adoption models with both an Amazon branded and managed services, technology and associated tools.

This means leveraging your existing Amazon accounts to simplify procurement, management, ongoing billing as well as leveraging their infrastructure. As a standalone gateway appliance (e.g. it does not have to be bundled as part of a specific backup, archive, replication or other data management tool), the idea is that you can insert the technology into your existing data center between your servers and storage to begin sending a copy of data off to Amazon S3. In addition to sending data to S3, the integrated functionality with other AWS services should make it easier to integrated with Elastic Cloud Compute (EC2) and Elastic Block storage (EBS) capabilities including snapshots for data protection.

Thus my first impression of AWS storage gateway at a high level view is good and interesting resulting in looking a bit deeper resulting in a second impression.

Second impression: Hmm, what does it really do and require, time to slow down and do more home work

Digging deeper and going through the various publicly available material (note can only comment or discuss on what is announced or publicly available) results in a second impression of wanting and needing to dig deeper based on some of caveats. Now granted and in fairness to Amazon, this is of course a beta release and hence while on first impression it can be easy to miss the notice that it is in fact a beta so keep in mind things can and hopefully will change.

Pricing aside, which means as with any cloud or managed storage service, you will want to do a cost analysis model just as you would for procuring physical storage, look into the cost of monthly gateway fee along with its associated physical service running VMware ESXi configuration that you will need to supply. Chances are that if you are an average sized SMB, you have a physical machine (PM) laying around that you can throw a copy of ESXi on to if you dont already have room for some more VMs on an existing one.

You will also need to assess the costs for using the S3 storage including space capacity charges, access and other fees as well as charges for doing snapshots or using other functionality. Again these are not unique to Amazon or their cloud gateway and should be best practices for any service or solution that you are considering. Amazon makes it easy by the way to see their base pricing for different tiers of availability, geographic locations and optional fees.

Speaking of accessing the cloud, and cloud conversations, you will also want to keep in mind what your networking bandwidth service requirements will be to move data to Amazon that might not already be doing so.

Another thing to consider with the AWS storage gateway is that it does not replace your local storage (that is unless you move your applications to Amazon EC2 and EBS), rather makes a copy of what every you save locally to a remote Amazon S3 storage pool. This can be good for high availability (HA), business continuance (BC), disaster recovery (DR) and compliance among other data management needs. However in your cost model you also need to keep in mind that you are not replacing your local storage, you are adding to it via the cloud which should be seen as complimenting and enhancing your private now to be hybrid environment.

Walking the cloud data protection talk

FWIW, I leverage a similar model where I use a service (Jungle Disk) where critical copies of my data get sent to that service which in turn places copies at Rack space (Jungledisks parent) and Amazon S3. What data goes to where depends on different policies that I have established. I also have local backup copies as well as master gold disaster copy stored in a secure offsite location. The idea is that when needed, I can get a good copy restored from my cloud providers quickly regardless of where I am if the local copy is not good. On the other hand, experience has already demonstrated that without sufficient network bandwidth services, if I need to bring back 100s of GBytes or TBytes of data quickly, Im going to be better off bring back onsite my master gold copy, then applying fewer, smaller updates from the cloud service. In other words, the technologies compliment each other.

By the way, a lesson learned here is that once my first copy is made which have data footprint reduction (DFR) techniques applied (e.g. compress, de dupe, optimized, etc), later copies occur very fast. However subsequent restores of those large files or volumes also takes longer to retrieve from the cloud vs. sending up changed versions. Thus be aware of backup vs. restore times, something of which will apply to any cloud provider and can be mitigated by appliances that do local caching. However also keep in mind that if a disaster occurs, will your local appliance be affected and its cache rendered useless.

Getting back to AWS storage gateway and my second impression is that at first it sounded great.

However then I realized it only supports iSCSI and FWIW, nothing wrong with iSCSI, I like it and recommend using it where applicable, even though Im not using it. I would like to have seen a NAS (either NFS and/or CIFS) support for a gateway making it easier for in my scenario different applications, servers and systems to use and leverage the AWS services, something that I can do with my other gateways provided via different software tools. Granted for those environments that already are using iSCSI for your servers that will be using AWS storage gateway, then this is a non issue while for others it is a consideration including cost (time) to factor in to prepare your environment for using the ability.

Depending on the amount of storage you have in your environment, the next item that caught my eye may or may not be an issue that the iSCSI gateway supports up to 1TB volumes and up to 12 of them hence a largest capacity of 12TB under management. This can be gotten around by using multiple gateways however the increased complexity balanced to the benefit the functionality is something to consider.

Third impression: Dig deeper, learn more, address various questions

This leads up to my third impression the need to dig deeper into what AWS storage gateway can and cannot do for various environments. I can see where it can be a fit for some environments while for others at least in its beta version will be a non starter. In the meantime, do your homework, look around at other options which ironically by having Amazon launching a gateway service may reinvigorate the market place of some of the standalone or embedded cloud gateway solution providers.

What is needed for using AWS storage gateway

In addition to having an S3 account, you will need to acquire for a monthly fee the storage gateway appliance which is software installed into a VMware ESXi hypervisor virtual machine (VM). The requirements are VMware ESXi hypervisor (v4.1) on a physical machine (PM) with at least 7.5GB of RAM and four (4) virtual processors assigned to the appliance VM along with 75GB of disk space for the Open Virtual Alliance (OVA) image installation and data. You will also need to have an proper sized network connection to Amazon. You will also need iSCSI initiators on either Windows server 2008, Windows 7 or Red Hat Enterprise Linux.

Note that the AWS storage gateway beta is optimized for block write sizes greater than 4Kbytes and warns that smaller IO sizes can cause overhead resulting in lost storage space. This is a consideration for systems that have not yet changed your file systems and volumes to use the larger allocation sizes.

Some closing thoughts, tips and comments:

Congratulations to Amazon for introducing and launching an AWS branded storage gateway.
Amazon brings trust the value of trust to a cloud relationship.
Initially I was excited about the idea of using a gateway that any of may systems could use my S3 storage pools with vs. using gateway access functions that are part of different tools such as my backup software or via Amazon web tools. Likewise I was excited by the idea of having an easy to install and use gateway that would allow me to grow in a cost effective way.
Keep in mind that this solution or at least in its beta version DOES NOT replace your existing iSCSI based storage needs, instead it compliments what you already have.
I hope Amazon listens carefully to what they customers and prospects want vs. need to evolve the functionality.
This announcement should reinvigorate some of the cloud appliance vendors as well as those who have embedded functionality to Amazon and other providers.
Keep bandwidth services and optimization in mind both for sending data as well as for when retrieving during a disaster or small file restore.
In concept, the AWS storage gateway is not all that different than appliances that do snapshots and other local and remote data protection such as those from Actifio, EMC (Recoverpoint), Falconstor or dedicated gateways such as those from Nasuni among others.
Here is a link to added AWS storage gateways frequently asked questions (FAQs).
If the AWS were available with a NAS interface, I would probably be activating it this afternoon even with some of their other requirements and cost aside.
Im still formulating my fourth impression which is going to take some time, perhaps if I can get Amazon to help sell more of my books so that I can get some money to afford to test the entire solution leveraging my existing S3, EC2 and EBS accounts I might do so in the future, otherwise for now, will continue to research.

Ok, nuff said for now, I need to get back to some other things while thinking about this all some more.
