StorageIO industry trends cloud, virtualization and big data

In this episode, I am at the Ceph day in Amsterdam Holland event at the Tobacco Theatre. My guest for this episode is Ceph (Cephalanthera) creator Sage Weil who is also the founder of inktank.com that provides services and support for the open source based Ceph project.

For those not familiar with Ceph, it is an open source distributed object scale out software platform that can be used for deploying cloud and managed services, general purpose storage for research, commercial, scientific, high performance computing (HPC) or high productivity computing (commercial) along with backup or data protection and archiving destinations.

During our conversation Sage presents an overview of what Ceph is (e.g. Ceph for non Dummies), where and how it can be used, some history of the project and how it fits in with or provides an alternative to other solutions. Sage also talks about the business or commercial considerations for open source based projects, importance of community and having good business mentors and partners as well as staying busy with his young family.

If you are a Ceph fan, gain more insight into Sage along with Ceph day sponsors Inktank and 42on. On the other hand, if you new to object storage, open source storage software or cloud storage, listen in to gain perspectives of where technology such as Ceph fits for public, private, hybrid or traditional environments.

Little data, big data and very big data (VBD) or big BS?

StorageIO industry trends cloud, virtualization and big data

This is an industry trends and perspective piece about big data and little data, industry adoption and customer deployment.

If you are in any way associated with information technology (IT), business, scientific, media and entertainment computing or related areas, you may have heard big data mentioned. Big data has been a popular buzzword bingo topic and term for a couple of years now. Big data is being used to describe new and emerging along with existing types of applications and information processing tools and techniques.

I routinely hear from different people or groups trying to define what is or is not big data and all too often those are based on a particular product, technology, service or application focus. Thus it should be no surprise that those trying to police what is or is not big data will often do so based on what their interest, sphere of influence, knowledge or experience and jobs depend on.

Traveling and big data images

Not long ago while out traveling I ran into a person who told me that big data is new data that did not exist just a few years ago. Turns out this person was involved in geology so I was surprised that somebody in that field was not aware of or working with geophysical, mapping, seismic and other legacy or traditional big data. Turns out this person was basing his statements on what he knew, heard, was told about or on sphere of influence around a particular technology, tool or approach.

Fwiw, if you have not figured out already, like cloud, virtualization and other technology enabling tools and techniques, I tend to take a pragmatic approach vs. becoming latched on to a particular bandwagon (for or against) per say.

Not surprisingly there is confusion and debate about what is or is not big data including if it only applies to new vs. existing and old data. As with any new technology, technique or buzzword bingo topic theme, various parties will try to place what is or is not under the definition to align with their needs, goals and preferences. This is the case with big data where you can routinely find proponents of Hadoop and Map reduce position big data as aligning with the capabilities and usage scenarios of those related technologies for business and other forms of analytics.

SAS software for big data

Not surprisingly the granddaddy of all business analytics, data science and statistic analysis number crunching is the Statistical Analysis Software (SAS) from the SAS Institute. If these types of technology solutions and their peers define what is big data then SAS (not to be confused with Serial Attached SCSI which can be found on the back-end of big data storage solutions) can be considered first generation big data analytics or Big Data 1.0 (BD1 ;) ). That means Hadoop Map Reduce is Big Data 2.0 (BD2 ;) ;) ) if you like, or dislike for that matter.

Funny thing about some fans and proponents or surrogates of BD2 is that they may have heard of BD1 like SAS with a limited understanding of what it is or how it is or can be used. When I worked in IT as a performance and capacity planning analyst focused on servers, storage, network hardware, software and applications I used SAS to crunch various data streams of event, activity and other data from diverse sources. This involved correlating data, running various analytic algorithms on the data to determine response times, availability, usage and other things in support of modeling, forecasting, tuning and trouble shooting. Hmm, sound like first generation big data analytics or Data Center Infrastructure Management (DCIM) and IT Service Management (ITSM) to anybody?

Now to be fair, comparing SAS, SPSS or any number of other BD1 generation tools to Hadoop and Map Reduce or BD2 second generation tools is like comparing apples to oranges, or apples to pears.

Lets move on as there is much more to what is big data than simply focus around SAS or Hadoop.

StorageIO industry trends cloud, virtualization and big data

Another type of big data are the information generated, processed, stored and used by applications that result in large files, data sets or objects. Large file, objects or data sets include low resolution and high-definition photos, videos, audio, security and surveillance, geophysical mapping and seismic exploration among others. Then there are data warehouses where transactional data from databases gets moved to for analysis in systems such as those from Oracle, Teradata, Vertica or FX among others. Some of those other tools even play (or work) in both traditional e.g. BD1 and new or emerging BD2 worlds.

This is where some interesting discussions, debates or disagreements can occur between those who latch onto or want to keep big data associated with being something new and usually focused around their preferred tool or technology. What results from these types of debates or disagreements is a missed opportunity for organizations to realize that they might already be doing or using a form of big data and thus have a familiarity and comfort zone with it.

By having a familiarity or comfort zone vs. seeing big data as something new, different, hype or full of FUD (or BS), an organization can be comfortable with the term big data. Often after taking a step back and looking at big data beyond the hype or fud, the reaction is along the lines of, oh yeah, now we get it, sure, we are already doing something like that so lets take a look at some of the new tools and techniques to see how we can extend what we are doing.

Likewise many organizations are doing big bandwidth already and may not realize it thinking that is only what media and entertainment, government, technical or scientific computing, high performance computing or high productivity computing (HPC) does. I’m assuming that some of the big data and big bandwidth pundits will disagree, however if in your environment you are doing many large backups, archives, content distribution, or copying large amounts of data for different purposes that consume big bandwidth and need big bandwidth solutions.

Yes I know, that’s apples to oranges and perhaps stretching the limits of what is or can be called big bandwidth based on somebody’s definition, taxonomy or preference. Hopefully you get the point that there is diversity across various environments as well as types of data and applications, technologies, tools and techniques.

StorageIO industry trends cloud, virtualization and big data

What about little data then?

I often say that if big data is getting all the marketing dollars to generate industry adoption, then little data is generating all the revenue (and profit or margin) dollars by customer deployment. While tools and technologies related to Hadoop (or Haydoop if you are from HDS) are getting industry adoption attention (e.g. marketing dollars being spent) revenues from customer deployment are growing.

Where big data revenues are strongest for most vendors today are centered around solutions for hosting, storing, managing and protecting big files, big objects. These include scale out NAS solutions for large unstructured data like those from Amplidata, Cray, Dell, Data Direct Networks (DDN), EMC (e.g. Isilon), HP X9000 (IBRIX), IBM SONAS, NetApp, Oracle and Xyratex among others. Then there flexible converged compute storage platforms optimized for analytics and running different software tools such as those from EMC (Greenplum), IBM (Netezza), NetApp (via partnerships) or Oracle among others that can be used for different purposes in addition to supporting Hadoop and Map reduce.

If little data is databases and things not generally lumped into the big data bucket, and if you think or perceive big data only to be Hadoop map reduce based data, then does that mean all the large unstructured non little data is then very big data or VBD?

StorageIO industry trends cloud, virtualization and big data

Of course the virtualization folks might want to if they have not already corner the V for Virtual Big Data. In that case, then instead of Very Big Data, how about very very Big Data (vvBD). How about Ultra-Large Big Data (ULBD), or High-Revenue Big Data (HRBD), granted the HR might cause some to think its unique for Health Records, or Human Resources, both btw leverage different forms of big data regardless of what you see or think big data is.

Does that then mean we should really be calling videos, audio, PACs, seismic, security surveillance video and related data to be VBD? Would this further confuse the market, or the industry or help elevate it to a grander status in terms of size (data file or object capacity, bandwidth, market size and application usage, market revenue and so forth)?

Do we need various industry consortiums, lobbyists or trade groups to go off and create models, taxonomies, standards and dictionaries based on their constituents needs and would they align with those of the customers, after all, there are big dollars flowing around big data industry adoption (marketing).

StorageIO industry trends cloud, virtualization and big data

What does this all mean?

Is Big Data BS?

First let me be clear, big data is not BS, however there is a lot of BS marketing BS by some along with hype and fud adding to the confusion and chaos, perhaps even missed opportunities. Keep in mind that in chaos and confusion there can be opportunity for some.

IMHO big data is real.

There are different variations, use cases and types of products, technologies and services that fall under the big data umbrella. That does not mean everything can or should fall under the big data umbrella as there is also little data.

What this all means is that there are different types of applications for various industries that have big and little data, virtual and very big data from videos, photos, images, audio, documents and more.

Big data is a big buzzword bingo term these days with vendor marketing big dollars being applied so no surprise the buzz, hype, fud and more.

Ok, nuff said, for now.

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.

How many degrees separate you and your information?

StorageIO industry trends cloud, virtualization and big data

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.

Image degrees of seperation

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.

Image degrees of seperation

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.

Image degrees of seperation and information transformation

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.

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.
