IT and data center sustainability, the other convergence zone

Storage I/O trends

IT and data center sustainability convergence

Recently Hailey Lynne McKeefry (@HaileyMcK), Editor in Chief over at Data Center Acceleration (@DataAccelerate) reached out for a conversation about well, data center themes and topics. Given Hailey’s background in covering technology as well as business supply chain we somehow ended up talking about business, IT and data center sustainability. Hailey wrote a piece about Driving for Datacenter Sustainability and in addition I was honored to be an invited guest for a live on-line chat yesterday (you can view the conversation here).

Excerpt from Haileys piece:

Too often, sustainability efforts in the datacenter are written off as feel-good, public relations efforts. In reality, green is about economics — and done well, it can save the datacenter tons of cash.

"You mention green, and datacenter managers run or cringe and roll their eyes, because there’s been so much green washing done in the past few years," said Greg Schulz, founder of IT consultancy StorageIO. "It’s really about green economics, though, and getting more work done with the same budget."

Many different faces of IT and data center sustainability

Granted, when you here the term sustainability, IT and data centers you may think of different things depending on your view or area of focus.

For some it will be Green or environmental focused such as use of renewable and EH&S themes, recycling among others Related to the previous item some will see sustainability as being tied to energy, either tied to cost, availability/accessibility, standby or alternative and renewable Yet for others, it will mean business continuance (BC), disaster recovery (DR), business resiliency (BR), high availability or reliability availability service (RAS) among others Then the economics concerns of keeping the business running to discuss top and bottom line concerns.

Otoh, if your focus is on one of the above or a subset of one of them, you might not view the other areas as being tied to sustainability.

It data center sustainability

Likewise, you might even want to not be included in another other, let alone share your area with others. For example if your focus is on security you may not want to see or hear that data protection is part of sustainability, not to mention backup/restore, bc, dr and so forth.

Learning, education and knowledge sustainability

Part of sustainability is also continuing to learn about new things not only in your field or focus area, also in adjacent spaces.

Keep in mind that there is more of a data center or information factory than just a building or facility with power, cooling as there are the technologies, tools, people, process, delivery/distribution network, warehouse for storing raw and finished material, metrics and management that all go into delivering the product which is information services.

Hence there are many aspects to IT and data center sustainability and thus think more pragmatically about sustaining information factories, however lets also be realistic and not jump the shark by declaring everything as sustainable ;).

Green IT deferral blamed on economic recession might be result of green gap

Storage I/O Industry Trends and Perspectives

I recently saw a comment somewhere that talked about Green IT being deferred or set aside due to lack of funding because of ongoing global economic turmoil. For those who see Green IT in the context of the green washing efforts that requiring spending to gain some benefits that I can understand. After all, if your goal is to simply go and be or be seen as being green, there is a cost to doing that.

With tight or shrinking IT budgets, there are other realities and while organizations may want to do the right thing helping the environment, however that is often seen as overhead to financial conscious management.

On the other hand, turn the green washing messaging off or at least dial-it back a bit as has been the case the past couple of years.

Expand the Green IT discussion or change it around a bit from that of being seen or perceived as being green by energy efficiency or avoidance to that of effectiveness, enhanced productivity, doing more with what you have or with less and there is a different opportunity.

That opportunity is to meet the financial and business goals or requirements that as a by-product help the environment. In other words, expand the focus of Green IT to that of economics and improving on resource effectiveness and the environment gets a free ride, or, Green gets self-funded.

The Green and Virtual Data Center Book addressing optimization, effectivness, productivity and economics

The challenge is what I refer to as the Green Gap, which is the disconnect between what is talked about (e.g. messaging) and thus perceived to be Green IT and where common IT opportunities exist (or missed opportunities have occurred).

Green IT or at least the tenants of driving efficiency and effectiveness to use energy more effectively, address recycling and waste, removable of hazardous substance and other items continues to thrive. However, the green washing is subsiding and overtime organizations will not be as dismissive of Green IT in the context of improving productivity, reducing complexity and costs, optimization and related themes tied to economics where the environment gets a free ride.

SNW Fall 2011 revisited and SNIA Emerald program

A couple of weeks ago I traveled down to Orlando Florida for a few days to attend the fall 2011 SNW (Storage Networking World) produced in conjunction by IDG Computerworld and the Storage Networking Industry Association (SNIA).

SNIA and SNW

While at the Orlando event, SNIA executive director Leo Legar asked me how many SNWs I had attended and my responses was on which continent?

My answer was part in fun however also serious as I have been attending SNWs (in addition to other SNIA events) for over ten years in both North and South America as well as in Europe including presenting SNIA tutorials and SNW sessions.

SNW is always good for meeting up with old friends and acquaintances along with meeting new ones including twitter tweeps (hashtag #snwusa #snw2011 @sniacloud @snwusa) and the recent event was no exception. Granted SNW is smaller than it was during its peak in the mid 2000s however it was great to go for a couple of days of meetings, checking out the expo hall and some sessions as well as getting out and about meeting people involved with servers, storage, networking, virtualization, cloud, hardware, software and services.

SNW remains as its name implies (Storage Networking World) an event around networking as in conversations, learning, knowledge exchange, information gathering and meetings not to mention the hands on lab. I found the two days I was there adequate to get the meetings and other activities I had planned, along with time for impromptu meetings. ANother observation was that during the peak of the large mega SNW events, while there were more meetings, they were also much shorter along the lines of speed dating vs. those a couple of weeks ago where there was time to have quality conversations.

Some of the news at the recent SNW event, involved SNIA and their Green Storage Initiative (GSI) announcing the availability of the Emerald program Green IT storage energy metrics that have been in the works for several years. The SNIA Emerald program consists of specifications, taxonomies, metrics and measurements standards to gauge various types of storage power or energy usage to gauge its effectiveness. In other words, yes, Green IT and Green storage are still alive, they just are not as trendy to talk about as they were a few years ago which a shift in focus towards productivity, effective use and supporting growth to help close the green gap and missed IT as well as business opportunities.

Also during the recent SNW event, I did a book signing event sponsored by SNIA. If you have not done so, check out the SNIA Cloud Storage Initiative (CSI) who arranged for several of my new book Cloud and Virtual Data Storage Networking to be given away. Book signings are fun in that I get to meet lots of people and hear what they are doing, encountering, looking for, have done, concerned or excited about. It was handy having SNIA CSI material available at the table as I was signing books and visiting with people to be able to give them information about things such as CDMI not to mention hearing what they were doing or looking for. Note to SNIA, if we do this again, lets make sure to have someone from the CSI at the table to join in the fun and conversations as there were some good ones. Learn more about the activities of the SNIA CSI including their Cloud Data Management Initiative (CDMI) here.

SNIA Cloud Storage Initiaive CSI

Thanks again to SNIA for arranging the book signing event and for those who were not able to get a copy of my new book before they ran out, my publisher CRC Press Taylor and Francis has arranged a special SNIA and SNW discount code. To take advantage of the SNIA and SNW discount code, go to the CRC Press web site (here) and apply the discount code KVK01 during checkout for catalog item K12375 (ISBN: 9781439851739).

30 percent discount code for Cloud and Virtual Data Storage Networking Book

Thanks again to Wayne Adams (@wma01606), Leo Legar and Michael Meleedy among others who arranged for a fantastic fall 2011 SNW event along with everyone who participated in the book signing event and other conversations while in Orlando and to those who were involved virtually via twitter.

Back to school shopping: Dude, Dell Digests 3PAR Disk storage

Dell

No sooner has the dust settled from Dells other recent acquisitions, its back to school shopping time and the latest bargain for the Round Rock Texas folks is bay (San Francisco) area storage vendor 3PAR for $1.15B. As a refresh, some of Dells more recent acquisitions including a few years ago $1.4B for EqualLogic, $3.9B for Perot systems not to mention Exanet, Kace and Ocarina earlier this year. For those interested, as of April 2010 reporting figures found here, Dell showed about $10B USD in cash and here is financial information on publicly held 3PAR (PAR).

Who is 3PAR
3PAR is a publicly traded company (PAR) that makes a scalable or clustered storage system with many built in advanced features typically associated with high end EMC DMX and VMAX as well as CLARiiON, in addition to Hitachi or HP or IBM enterprise class solutions. The Inserv (3PARs storage solution) combines hardware and software providing a very scalable solution that can be configured for smaller environments or larger enterprise by varying the number of controllers or processing nodes, connectivity (server attachment) ports, cache and disk drives.

Unlike EqualLogic which is more of a mid market iSCSI only storage system, the 3PAR Inserv is capable of going head to head with the EMC CLARiiON as well as DMC or VMAX systems that support a mix of iSCSI and Fibre Channel or NAS via gateway or appliances. Thus while there were occasional competitive situations between 3PAR and Dell EqualLogic, they for the most part were targeted at different market sectors or customers deployment scenarios.

What does Dell get with 3PAR?

  • A good deal if not a bargain on one of the last new storage startup pure plays
  • A public company that is actually generating revenue with a large and growing installed base
  • A seasoned sales force who knows how to sell into the enterprise storage space against EMC, HP, IBM, Oracle/SUN, Netapp and others
  • A solution that can scale in terms of functionality, connectivity, performance, availability, capacity and energy efficiency (PACE)
  • Potential route to new markets where 3PAR has had success, or to bridge gaps where both have played and competed in the past
  • Did I say a company with an established footprint of installed 3PAR Inserv storage systems and good list of marquee customers
  • Ability to sell a solution that they own the intellectual property (IP) instead of that of partner EMC
  • Plenty of IP that can be leveraged within other Dell solutions, not to mention combine 3PAR with other recently acquired technologies or companies.

On a lighter note, Dell picks up once again Marc Farley who was with them briefly after the EqualLogic acquisition who then departed to 3PAR where he became director of social media including launch of Infosmack on Storage Monkeys with co host Greg Knieriemen (@Knieriemen). Of course the twitter world and traditional coconut wires are now speculating where Farley will go next that Dell may end up buying in the future.

What does this mean for Dell and their data storage portfolio?
While in no ways all inclusive or comprehensive, table 1 provides a rough framework of different price bands, categories, tiers and market or application segments requiring various types of storage solutions where Dell can sell into.

Table 1: Sampling of various tiers, architectures, functionality and storage solution options

Clarifying some of the above categories in table 1:

Servers: Application servers or computers running Windows, Linux, HyperV, VMware or other applications, operating systems and hypervisors.

Services: Professional and consulting services, installation, break fix repair, call center, hosting, managed services or cloud solutions

Enterprise storage: Large scale (hundreds to thousands of drives, many front end as well as back ports, multiple controllers or storage processing engines (nodes), large amount of cache and equally strong performance, feature rich functionality, resilient and scalable.

Data footprint impact reduction: Archive, data management, compression, dedupe, thin provision among other techniques. Read more here and here.

Data preservation: Archiving for compliance and non regulatory applications or data including software, hardware, services.

General data protection: Excluding physical or logical data security (firewalls, dlp, etc), this would be backup/restore with encryption, replication, snapshots, hardware and software to support BC, DR and normal business operations. Read more about data protection options for virtual and physical storage here.

Scale out NAS: Clustered NAS, bulk unstructured storage, cloud storage system or file system. Read more about clustered storage here. HP has their eXtreme X series of scale out and bulk storage systems as well as gateways. These leverage IBRIX and Polyserve which were bought by HP as software, or as a solution (HP servers, storage and software), perhaps with optional data reduction software such as Ocarina OEMed by Dell. Dell now has Exanet which they bought recently as software, or as a solution running on Dell servers, with either SAS, iSCSI or FC back end storage plus optional data footprint reduction software such as Ocarina. IBM has GPFS as a software solution running on IBM or other vendors servers with attached storage, or as a solution such as SONAS with IBM servers running software with IBM DS mid range storage. IBM also OEMs Netapp as the N series.

General purpose NAS: NAS (NFS and CIFS or optional AFP and pNFS) for everyday enterprise (or SME/SMB) file serving and sharing

Mid market multi protocol block: For SMB to SME environments that need scalable shared (SAN) scalable block storage using iSCSI, FC or FCoE

Scalable SMB iSCSI: For SMB to SME environments that need scalable iSCSI storage with feature rich functionality including built in virtualization

Entry level shared block: Block storage with flexibility to support iSCSI, SAS or Fibre Channel with optional NAS support built in or available via a gateway. For example external SAS RAID shared storage between 2 or more servers configured in a HyeprV or VMware clustered that do not need or can afford higher cost of iSCSI. Another example would be shared SAS (or iSCSI or Fibre Channel) storage attached to a server running storage software such as clustered file system (e.g. Exanet) or VTL, Dedupe, Backup, Archiving or data footprint reduction tools or perhaps database software where higher cost or complexity of an iSCSI or Fibre Channel SAN is not needed. Read more about external shared SAS here.

Entry level unified multifunction: This is storage that can do block and file yet is scaled down to meet ease of acquisition, ease of sale, channel friendly, simplified deployment and installation yet affordable for SMBs or larger SOHOs as well as ROBOs.

Low end SOHO: Storage that can scale down to consumer, prosumer or lower end of SMB (e.g. SOHO) providing mix of block and file, yet priced and positioned below higher price multifunction systems.

Wait a minute, are that too many different categories or types of storage?

Perhaps, however it also enables multiple tools (tiers of technologies) to be in a vendors tool box, or, in an IT professionals tool bin to address different challenges. Lets come back to this in a few moments.

 

Some Industry trends and perspectives (ITP) thoughts:

How can Dell with 3PAR be an enterprise play without IBM mainframe FICON support?
Some would say forget about it, mainframes are dead thus not a Dell objective even though EMC, HDS and IBM sell a ton of storage into those environments. However, fair enough argument and one that 3PAR has faced for years while competing with EMC, HDS, HP, IBM and Fujitsu thus they are versed in how to handle that discussion. Thus the 3PAR teams can help the Dell folks determine where to hunt and farm for business something that many of the Dell folks already know how to do. After all, today they have to flip the business to EMC or worse.

If truly pressured and in need, Dell could continue reference sales with EMC for DMX and VMAX. Likewise they could also go to Bustech and/or Luminex who have open systems to mainframe gateways (including VTL support) under a custom or special solution sale. Ironically EMC has OEMed in the past Bustech to transform their high end storage into Mainframe VTLs (not to be confused with Falconstor or Quantum for open system) as well as Datadomain partnered with Luminex.

BTW, did you know that Dell has had for several years a group or team that handles specialized storage solutions addressing needs outside the usual product portfolio?

Thus IMHO Dells enterprise class focus will be that for open systems large scale out where they will compete with EMC DMX and VMAX, HDS USP or their soon to be announced enhancements, HP and their Hitachi Japan OEMed XP, IBM and the DS8000 as well as the seldom heard about yet equally scalable Fujitsu Eternus systems.

 

Why only 1.15B, after all they paid 1.4B for EqualLogic?
IMHO, had this deal occurred a couple of years ago when some valuations were still flying higher than today, and 3PAR were at their current sales run rate, customer deployment situations, it is possible the amount would have been higher, either way, this is still a great value for both Dell and 3PAR investors, customers, employees and partners.

 

Does this mean Dell dumps EMC?
Near term I do not think Dell dumps the EMC dudes (or dudettes) as there is still plenty of business in the mid market for the two companies. However, over time, I would expect that Dell will unleash the 3PAR folks into the space where normally a CLARiiON CX would have been positioned such as deals just above where EqualLogic plays, or where Fibre Channel is preferred. Likewise, I would expect Dell to empower the 3PAR team to go after additional higher end deals where a DMX or VMAX would have been the previous option not to mention where 3PAR has had success.

This would also mean extending into sales against HP EVA and XPs, IBM DS5000 and DS8000 as well as XIV, Oracle/Sun 6000 and 7000s to name a few. In other words there will be some spin around coopition, however longer term you can read the writing on the wall. Oh, btw, lest you forget, Dell is first and foremost a server company who now is getting into storage in a much bigger way and EMC is first and foremost a storage company who is getting into severs via VMware as well as their Cisco partnerships.

Are shots being fired across each other bows? I will leave that up to you to speculate.

 

Does this mean Dell MD1000/MD3000 iSCSI, SAS and FC disappears?
I do not think so as they have had a specific role for entry level below where the EqualLogic iSCSI only solution fits providing mixed iSCSI, SAS and Fibre Channel capabilities to compete with the HP MSA2000 (OEMed by Dothill) and IBM DS3000 (OEMed from LSI). While 3PAR could be taken down into some of these markets, which would also potentially dilute the brand and thus premium margin of those solutions.

Likewise, there is a play with server vendors to attach shared SAS external storage to small 2 and 4 node clusters for VMware, HyperV, Exchange, SQL, SharePoint and other applications where iSCSI or Fibre Channel are to expensive or not needed or where NAS is not a fit. Another play for the shared external SAS attached is for attaching low cost storage to scale out clustered NAS or bulk storage where software such as Exanet runs on a Dell server. Take a closer look at how HP is supporting their scale out as well as IBM and Oracle among others. Sure you can find iSCSI or Fibre Channel or even NAS back end to file servers. However growing trend of using shared SAS.

 

Does Dell now have too many different storage systems and solutions in their portfolio?
Possibly depending upon how you look at it and certainly the potential is there for revenue prevention teams to get in the way of each other instead of competing with external competitors. However if you compare the Dell lineup with those of EMC, HP, IBM and Oracle/Sun among others, it is not all that different. Note that HP, IBM and Oracle also have something in common with Dell in that they are general IT resource providers (servers, storage, networks, services, hardware and software) as compared to other traditional storage vendors.

Consequently if you look at these vendors in terms of their different markets from consumer to prosumer to SOHO at the low end of the SMB to SME that sits between SMB and enterprise, they have diverse customer needs. Likewise, if you look at these vendors server offerings, they too are diverse ranging from desktops to floor standing towers to racks, high density racks and blade servers that also need various tiers, architectures, price bands and purposed storage functionality.

 

What will be key for Dell to make this all work?
The key for Dell will be similar to that of their competitors which is to clearly communicate the value proposition of the various products or solutions, where, who and what their target markets are and then execute on those plans. There will be overlap and conflict despite the best spin as is always the case with diverse portfolios by vendors.

However if Dell can keep their teams focused on expanding their customer footprints at the expense of their external competition vs. cannibalizing their own internal product lines, not to mention creating or extending into new markets or applications. Consequently Dell now has many tools in their tool box and thus need to educate their solution teams on what to use or sell when, where, why and how instead of just having one tool or a singular focus. In other words, while a great solution, Dell no longer has to respond with the solution to everything is iSCSI based EqualLogic.

Likewise Dell can leverage the same emotion and momentum behind the EqualLogic teams to invigorate and unleash the best with 3PAR teams and solution into or onto the higher end of the SMB, SME and enterprise environments.

Im still thinking that Exanet is a diamond in the rough for Dell where they can install the clustered scalable NAS software onto their servers and use either lower end shared SAS RAID (e.g. MD3000), or iSCSI (MD3000, EqualLogic or 3PAR) or higher end Fibre Channel with 3PAR) for scale out, cloud and other bulk solutions competing with HP, Oracle and IBM. Dell still has the Windows based storage server for entry level multi protocol block and file capabilities as well as what they OEM from EMC.

 

Is Dell done shopping?
IMHO I do not think so as there are still areas where Dell can extend their portfolio and not just in storage. Likewise there are still some opportunities or perhaps bargains out there for fall and beyond acquisitions.

 

Does this mean that Dell is not happy with EqualLogic and iSCSI
Simply put from my perspective talking with Dell customers, prospects, and partners and seeing them all in action nothing could be further from Dell not being happy with iSCSI or EqualLogic. Look at this as being a way to extend the Dell story and capabilities into new markets, granted the EqualLogic folks now have a new sibling to compete with internal marketing and management for love and attention.

 

Isnt Dell just an iSCSI focused company?
A couple of years I was quoted in one of the financial analysis reports as saying that Dell needed to remain open to various forms of storage instead of becoming singularly focused on just iSCSI as a result of the EqualLogic deal. I standby that statement in that Dell to be a strong enterprise contender needs to have a balanced portfolio across different price or market bands, from block to file, from shared SAS to iSCSI to Fibre Channel and emerging FCoE.

This also means supporting traditional NAS across those different price band or market sectors as well as support for emerging and fast growing unstructured data markets where there is a need for scale out and bulk storage. Thus it is great to see Dell remaining open minded and not becoming singularly focused on just iSCSI instead providing the right solution to meet their diverse customer as well as prospect needs or opportunities.

While EqualLogic was and is a very successfully iSCSI focused storage solution not to mention one that Dell continues to leverage, Dell is more than just iSCSI. Take a look at Dells current storage line up as well as up in table 1 and there is a lot of existing diversity. Granted some of that current diversity is via partners which the 3PAR deal helps to address. What this means is that iSCSI continues to grow in popularity however there are other needs where shared SAS or Fibre Channel or FCoE will be needed opening new markets to Dell.

 

Bottom line and wrap up (for now)
This is a great move for Dell (as well as 3PAR) to move up market in the storage space with less reliance on EMC. Assuming that Dell can communicate the what to use when, where, why and how to both their internal teams, partners as well as industry and customers not to mention then execute on, they should have themselves a winner.

Will this deal end up being an even better bargain than when Dell paid $1.4B for EqualLogic?

Not sure yet, it certainly has potential if Dell can execute on their plans without losing momentum in any other their other areas (products).

Whats your take?

The New Green IT: Productivity, supporting growth, doing more with what you have

Energy efficient and money saving Green IT or storage optimization are often associated to mean things like MAID, Intelligent Power Management (IPM) for servers and storage disk drive spin down or data deduplication. In other words, technologies and techniques to minimize or avoid power consumption as well as subsequent cooling requirements which for some data, applications or environments can be the case. However there is also shifting from energy avoidance to that of being efficient, effective, productive not to mention profitable as forms of optimization. Collectively these various techniques and technologies help address or close the Green Gap and can reduce the amount of Green IT confusion in the form of boosting productivity (same goes for servers or networks) in terms of more work, IOPS, bandwidth, data moved, frames or packets, transactions, videos or email processed per watt per second (or other unit of time).

Its US Census time, What about IT Data Centers?

It is that once a decade activity time this year referred to as the US 2010 Census.

With the 2010 census underway, not to mention also time for completing and submitting your income tax returns, if you are in IT, what about measuring, assessing, taking inventory or analyzing your data and data center resources?

US 2010 Cenus formsUS 2010 Cenus forms
Figure 1: IT US 2010 Census forms

Have you recently taken a census of your data, data storage, servers, networks, hardware, software tools, services providers, media, maintenance agreements and licenses not to mention facilities?

Likewise have you figured out what if any taxes in terms of overhead or burden exists in your IT environment or where opportunities to become more optimized and efficient to get an IT resource refund of sorts are possible?

If not, now is a good time to take a census of your IT data center and associated resources in what might also be called an assessment, review, inventory or survey of what you have, how its being used, where and who is using and when along with associated configuration, performance, availability, security, compliance coverage along with costs and energy impact among other items.

IT Data Center Resources
Figure 2: IT Data Center Metrics for Planning and Forecasts

How much storage capacity do you have, how is it allocated along with being used?

What about storage performance, are you meeting response time and QoS objectives?

Lets not forget about availability, that is planned and unplanned downtime, how have your systems been behaving?

From an energy or power and cooling standpoint, what is the consumption along with metrics aligned to productivity and effectiveness. These include IOPS per watt, transactions per watt, videos or email along with web clicks or page views per watt, processor GHz per watt along with data movement bandwidth per watt and capacity stored per watt in a given footprint.

Other items to look into for data centers besides storage include servers, data and I/O networks, hardware, software, tools, services and other supplies along with physical facility with metrics such as PUE. Speaking of optimization, how is your environment doing, that is another advantage of doing a data center census.

For those who have completed and sent in your census material along with your 2009 tax returns, congratulations!

For others in the US who have not done so, now would be a good time to get going on those activities.

Likewise, regardless of what country or region you are in, its always a good time to take a census or inventory of your IT resources instead of waiting every ten years to do so.

Ok, nuff said.

Technorati tags: Trends

RAID Relevance Revisited

Following up from some previous posts on the topic, a continued discussion point in the data storage industry is the relevance (or lack there) of RAID (Redundant Array of Independent Disks).

These discussions tend to evolve around how RAID is dead due to its lack of real or perceived ability to continue scaling in terms of performance, availability, capacity, economies or energy capabilities needed or when compared to those of newer techniques, technologies or products.

RAID Relevance

While there are many new and evolving approaches to protecting data in addition to maintaining availability or accessibility to information, RAID despite the fan fare is far from being dead at least on the technology front.

Sure, there are issues or challenges that require continued investing in RAID as has been the case over the past 20 years; however those will also be addressed on a go forward basis via continued innovation and evolution along with riding technology improvement curves.

Now from a marketing standpoint, ok, I can see where the RAID story is dead, boring, and something new and shiny is needed, or, at least change the pitch to sound like something new.

Consequently, when being long in the tooth and with some of the fore mentioned items among others, older technologies that may be boring or lack sizzle or marketing dollars can and often are declared dead on the buzzword bingo circuit. After all, how long now has the industry trade group RAID Advisory Board (RAB) been missing in action, retired, spun down, archived or ILMed?

RAID remains relevant because like other dead or zombie technologies it has reached the plateau of productivity and profitability. That success is also something that emerging technologies envy as their future domain and thus a classic marketing move is to declare the incumbent dead.

The reality is that RAID in all of its various instances from hardware to software, standard to non-standard with extensions is very much alive from the largest enterprise to the SMB to the SOHO down into consumer products and all points in between.

Now candidly, like any technology that is about 20 years old if not older after all, the disk drive is over 50 years old and been declared dead for how long now?.RAID in some ways is long in the tooth and there are certainly issues to be addressed as have been taken care of in the past. Some of these include the overhead of rebuilding large capacity 1TB, 2TB and even larger disk drives in the not so distant future.

There are also issues pertaining to distributed data protection in support of cloud, virtualized or other solutions that need to be addressed. In fact, go way way back to when RAID appeared commercially on the scene in the late 80s and one of the value propositions among others was to address the reliability of emerging large capacity multi MByte sized SCSI disk drives. It seems almost laughable today that when a decade later, when the 1GB disk drives appeared in the market back in the 90s that there was renewed concern about RAID and disk drive rebuild times.

Rest assured, I think that there is a need and plenty of room for continued innovate evolution around RAID related technologies and their associated storage systems or packaging on a go forward basis.

What I find interesting is that some of the issues facing RAID today are similar to those of a decade ago for example having to deal with large capacity disk drive rebuild, distributed data protecting and availability, performance, ease of use and so the list goes.

However what happened was that vendors continued to innovate both in terms of basic performance accelerated rebuild rates with improvements to rebuild algorithms, leveraged faster processors, busses and other techniques. In addition, vendors continued to innovate in terms of new functionality including adopting RAID 6 which for the better part of a decade outside of a few niche vendors languished as one of those future technologies that probably nobody would ever adopt, however we know that to be different now and for the past several years. RAID 6 is one of those areas where vendors who do not have it are either adding it, enhancing it, or telling you why you do not need it or why it is no good for you.

An example of how RAID 6 is being enhanced is boosting performance on normal read and write operations along with acceleration of performance during disk rebuild. Also tied to RAID 6 and disk drive rebuild are improvements in controller design to detect and proactively make repairs on the fly to minimize or eliminate errors or diminished the need for drive rebuilds, similar to what was done in previous generations. Lets also not forget the improvements in disk drives boosting performance, availability, capacity and energy improvements over time.

Funny how these and other enhancements are similar to those made to RAID controllers hardware and software fine tuning them in the early to mid 2000s in support for high capacity SATA disk drives that had different RAS characteristics of higher performance lower capacity enterprise drives.

Here is my point.

RAID to some may be dead while others continue to rely on it. Meanwhile others are working on enhancing technologies for future generations of storage systems and application requirements. Thus in different shapes, forms, configurations, feature; functionality or packaging, the spirit of RAID is very much alive and well remaining relevant.

Regardless of if a solution using two or three disk mirroring for availability, or RAID 0 fast SSD or SAS or FC disks in a stripe configuration for performance with data protection via rapid restoration from some other low cost medium (perhaps RAID 6 or tape), or perhaps single, dual or triple parity protection, or if using small block or multiMByte or volume based chunklets, let alone if it is hardware or software based, local or disturbed, standard or non standard, chances are there is some theme of RAID involved.

Granted, you do not have to call it RAID if you prefer!

As a closing thought, if RAID were no longer relevant, than why do the post RAID, next generation, life beyond RAID or whatever you prefer to call them technologies need to tie themselves to the themes of RAID? Simple, RAID is still relevant in some shape or form to different audiences as well as it is a great way of stimulating discussion or debate in a constantly evolving industry.

BTW, Im still waiting for the revolutionary piece of hardware that does not require software, and the software that does not require hardware and that includes playing games with server less servers using hypervisors :) .

Provide your perspective on RAID and its relevance in the following poll.

Here are some additional related and relevant RAID links of interests:

Stay tuned for more about RAIDs relevance as I dont think we have heard the last on this.

Is MAID Storage Dead? I Dont Think So!

Some vendors are doing better than others and first generation MAID (Massive or monolithic Array of Idle Disks) might be dead or about to be deceased, spun down or put into a long term sleep mode, it is safe to say that second generation MAID (e.g. MAID 2.0) also known as intelligent power management (IPM) is alive and doing well.

In fact, IPM is not unique to disk storage or disk drives as it is also a technique found in current generation of processors such as those from Intel (e.g. Nehalem) and others.

Other names for IPM include adaptive voltage scaling (AVS), adaptive voltage scaling optimized (AVSO) and adaptive power management (APM) among others.

The basic concept is to vary the amount of power being used to the amount of work and service level needed at a point in time and on a granular basis.

For example, first generation MAID or drive spin down as deployed by vendors such as Copan, which is rumored to be in the process of being spun down as a company (see blog post by a former Copan employee) were binary. That is, a disk drive was either on or off, and, that the granularity was the entire storage system. In the case of Copan, the granularly was that a maximum of 25% of the disks could ever be spun up at any point in time. As a point of reference, when I ask IT customers why they dont use MAID or IPM enabled technology they commonly site concerns about performance, or more importantly, the perception of bad performance.

CPU chips have been taking the lead with the ability to vary the voltage and clock speed, enabling or disabling electronic circuitry to align with amount of work needing to be done at a point in time. This more granular approach allows the CPU to run at faster rates when needed, slower rates when possible to conserve energy (here, here and here).

A common example is a laptop with technology such as speed step, or battery stretch saving modes. Disk drives have been following this approach by being able to vary their power usage by adjusting to different spin speeds along with enabling or disabling electronic circuitry.

On a granular basis, second generation MAID with IPM enabled technology can be done on a LUN or volume group basis across different RAID levels and types of disk drives depending on specific vendor implementation. Some examples of vendors implementing various forms of IPM for second generation MAID to name a few include Adaptec, EMC, Fujitsu Eternus, HDS (AMS), HGST (disk drives), Nexsan and Xyratex among many others.

Something else that is taking place in the industry seems to be vendors shying away from using the term MAID as there is some stigma associated with performance issues of some first generation products.

This is not all that different than what took place about 15 years ago or so when the first purpose built monolithic RAID arrays appeared on the market. Products such as the SF2 aka South San Francisco Forklift company product called Failsafe (here and here) which was bought by MTI with patents later sold to EMC.

Failsafe, or what many at DEC referred to as Fail Some was a large refrigerator sized device with 5.25” disk drives configured as RAID5 with dedicated hot spare disk drives. Thus its performance was ok for the time doing random reads, however writes in the pre write back cache RAID5 days was less than spectacular.

Failsafe and other early RAID (and here) implementations received a black eye from some due to performance, availability and other issues until best practices and additional enhancements such as multiple RAID levels appeared along with cache in follow on products.

What that trip down memory (or nightmare) lane has to do with MAID and particularly first generation products that did their part to help establish new technology is that they also gave way to second, third, fourth, fifth, sixth and beyond generations of RAID products.

The same can be expected as we are seeing with more vendors jumping in on the second generation of MAID also known as drive spin down with more in the wings.

Consequently, dont judge MAID based solely on the first generation products which could be thought of as advanced technology production proof of concept solutions that will have paved the way for follow up future solutions.

Just like RAID has become so ubiquitous it has been declared dead making it another zombie technology (dead however still being developed, produced, bought and put to use), follow on IPM enabled generations of technology will be more transparent. That is, similar to finding multiple RAID levels in most storage, look for IPM features including variable drive speeds, power setting and performance options on a go forward basis. These newer solutions may not carry the MAID name, however the sprit and function of intelligent power management without performance compromise does live on.

The other Green Storage: Efficiency and Optimization

Some believe that green storage is specifically designed to reduce power and cooling costs.

The reality is that there are many ways to reduce environmental impact while enhancing the economics of data storage besides simply booting utilizing.

These include optimizing data storage capacity as well as boosting performance to increase productivity per watt of energy used when work needs to be done.

Some approaches require new hardware or software while others can be accomplished with changes to management including reconfiguration leveraging insight and awareness of resource needs.

What is the Future of Servers?

Recently I provided some comments and perspectives on the future of servers in an article over at Processor.com.

In general, blade servers will become more ubiquitous, that is they wont go away, rather become more common place with even higher density processors with more cores and performance along with faster I/O and larger memory capacity per given footprint.

While the term blade server may fade giving way to some new term or phrase, rest assured their capabilities and functionality will not disappear, rather be further enhanced to support virtualization with VMware vsphere, Microsoft HyperV, Citrix/Zen along with public and private clouds, both for consolidation and in the next wave of virtualization called life beyond consolidation.

The other trend is that not only will servers be able to support more processing and memory per footprint; they will also do that drawing less energy requiring lower cooling demands, hence more Ghz per watt along with energy savings modes when less work needs to be performed.

Another trend is around convergence both in terms of packaging along with technology improvements from a server, I/O networking and storage perspective. For example, enhancements to shared PCIe with I/O virtualization, hypervisor optimization, and integration such as the recently announced EMC, Cisco, Intel and VMware VCE coalition and vblocks.

Justifying Green IT and Home Hardware Upgrades with EnergyStar

Energy Star

Have you seen the TV commercials or print advertisements where an energy star washer is mentioned as so efficient that the savings from reduced power consumption are enough to pay for the dryer? If not, check out the EPA Energy Star website for information about various programs, savings and efficiency options to learn more

What does this have to do with servers, storage, networking, data centers or other IT equipment?

Simple, if you are not aware, Energy Star for Servers now exits and is being enhanced while good progress is being made on the Energy Star for storage program.

The Energy Star for household appliances has been around a bit longer and more refined, something that I anticipated the server and storage programs to follow-suit with over time.

What really caught my eye with the commercial is the focus on closing the green gap, that is instead of the green environmental impact savings of an appliance that uses less power and subsequent carbon footprint benefits, the message is to the economic hot button. That is, switch to more energy efficient technology that allows more work to done at a lower overall cost and the savings can help self fund the enhancements.

For example, a more energy efficient server that can do more work or GHz per watt of energy when needed, or, to go into lower power modes (intelligent power management: IPM). Low power modes do not necessarily mean turning completely off, rather, drawing less energy and subsequently lower cooling demands during slow periods such as with new Intel Nehalem and other processors.

From a disk storage perspective, energy efficiency is often thought to be avoidance or turning disk drives off boosting capacity and squeezing data footprints.

However energy efficiency and savings can also be achieved by slowing a disk drive down or turning of some of the electronics to reduce energy consumption and heat generation.

Other forms of energy savings include thin provisioning and deduplication however another form of energy efficiency for storage is boosting performance. That is, doing more work per watt of energy for active or time sensitive applications or usage scenarios.

Thus there is another Green IT, one that provides both economic and environmental benefits!

Saving Money with Green IT: Time To Invest In Information Factories

There is a good and timely article titled Green IT Can Save Money, Too over at Business Week that has a familiar topic and theme for those who read this blog or other content, articles, reports, books, white papers, videos, podcasts or in-person speaking and keynote sessions that I have done..

I posted a short version of this over there, here is the full version that would not fit in their comment section.

Short of calling it Green IT 2.0 or the perfect storm, there is a resurgence and more importantly IMHO a growing awareness of the many facets of Green IT along with Green in general having an economic business sustainability aspect.

While the Green Gap and confusion still exists, that is, the difference between what people think or perceive and actual opportunities or issues; with growing awareness, it will close or at least narrow. For example, when I regularly talk with IT professionals from various sized, different focused industries across the globe in diverse geographies and ask them about having to go green, the response is in the 7-15% range (these are changing) with most believing that Green is only about carbon footprint.

On the other hand, when I ask them if they have power, cooling, floor space or other footprint constraints including frozen or reduced budgets, recycling along with ewaste disposition or RoHS requirements, not to mention sustaining business growth without negatively impacting quality of service or customer experience, the response jumps up to 65-75% (these are changing) if not higher.

That is the essence of the green gap or disconnect!

Granted carbon dioxide or CO2 reduction is important along with NO2, water vapors and other related issues, however there is also the need to do more with what is available, stretch resources and footprints do be more productive in a shrinking footprint. Keep in mind that there is no such thing as an information, data or processing recession with all indicators pointing towards the need to move, manage and store larger amounts of data on a go forward basis. Thus, the need to do more in a given footprint or constraint, maximizing resources, energy, productivity and available budgets.

Innovation is the ability to do more with less at a lower cost without compromise on quality of service or negatively impacting customer experience. Regardless of if you are a manufacturer, or a service provider including in IT, by innovating with a diverse Green IT focus to become more efficient and optimized, the result is that your customers become more enabled and competitive.

By shifting from an avoidance model where cost cutting or containment are the near-term tactical focus to an efficiency and productivity model via optimization, net unit costs should be lowered while overall service experience increase in a positive manner. This means treating IT as an information factory, one that needs investment in the people, processes and technologies (hardware, software, services) along with management metric indicator tools.

The net result is that environmental or perceived Green issues are addressed and self-funded via the investment in Green IT technology that boosts productivity (e.g. closing or narrowing the Green Gap). Thus, the environmental concerns that organizations have or need to address for different reasons yet that lack funding get addressed via funding to boost business productivity which have tangible ROI characteristics similar to other lean manufacturing approaches.

Here are some additional links to learn more about these and other related themes:

Have a read over at Business Week about how Green IT Can Save Money, Too while thinking about how investing in IT infrastructure productivity (Information Factories) by becoming more efficient and optimized helps the business top and bottom line, not to mention the environment as well.

EPA Energy Star for Data Center Storage Update

EPA Energy Star

Following up on a recent post about Green IT, energy efficiency and optimization for servers, storage and more, here are some additional  thoughts, perspectives along with industry activity around the U.S. Environmental Protection Agency (EPA) Energy Star for Server, Data Center Storage and Data Centers.

First a quick update, Energy Star for Servers is in place with work now underway on expanding and extending beyond the first specification. Second is that Energy Star for Data Center storage definition is well underway including a recent workshop to refine the initial specification along with discussion for follow-on drafts.

Energy Star for Data Centers is also currently undergoing definition which is focused more on macro or facility energy (notice I did not say electricity) efficiency as opposed to productivity or effectiveness, items that the Server and Storage specifications are working towards.

Among all of the different industry trade or special interests groups, at least on the storage front the Storage Networking Industry Association (SNIA) Green Storage Initiative (GSI) and their Technical Work Groups (TWG) have been busily working for the past couple of years on taxonomies, metrics and other items in support of EPA Energy Star for Data Center Storage.

A challenge for SNIA along with others working on related material pertaining to storage and efficiency is the multi-role functionality of storage. That is, some storage simply stores data with little to no performance requirements while other storage is actively used for reading and writing. In addition, there are various categories, architectures not to mention hardware and software feature functionality or vendors with different product focus and interests.

Unlike servers that are either on and doing work, or, off or in low power mode, storage is either doing active work (e.g. moving data), storing in-active or idle data, or a combination of both. Hence for some, energy efficiency is about how much data can be stored in a given footprint with the least amount of power known as in-active or idle measurement.

On the other hand, storage efficiency is also about using the least amount of energy to produce the most amount of work or activity, for example IOPS or bandwidth per watt per footprint.

Thus the challenge and need for at least a two dimensional  model looking at, and reflecting different types or categories of storage aligned for active or in-active (e.g. storing) data enabling apples to apples, vs. apples to oranges comparison.

This is not all that different from how EPA looks at motor vehicle categories of economy cars, sport utility, work or heavy utility among others when doing different types of work, or, in idle.

What does this have to do with servers and storage?

Simple, when a server powers down where does its data go? That’s right, to a storage system using disk, ssd (RAM or flash), tape or optical for persistency. Likewise, when there is work to be done, where does the data get read into computer memory from, or written to? That’s right, a storage system. Hence the need to look at storage in a multi-tenant manner.

The storage industry is diverse with some vendors or products focused on performance or activity, while others on long term, low cost persistent storage for archive, backup, not to mention some doing a bit of both. Hence the nomenclature of herding cats towards a common goal when different parties have various interests that may conflict yet support needs of various customer storage usage requirements.

Figure 1 shows a simplified, streamlined storage taxonomy that has been put together by SNIA representing various types, categories and functions of data center storage. The green shaded areas are a good step in the right direction to simplify yet move towards realistic and achievable befits for storage consumers.


Figure 1 Source: EPA Energy Star for Data Center Storage web site document

The importance of the streamlined SNIA taxonomy is to help differentiate or characterize various types and tiers of storage (Figure 2) products facilitating apples to apples comparison instead of apples or oranges. For example, on-line primary storage needs to be looked at in terms of how much work or activity per energy footprint determines efficiency.


Figure 2: Tiered Storage Example

On other hand, storage for retaining large amounts of data that is in-active or idle for long periods of time should be looked at on a capacity per energy footprint basis. While final metrics are still being flushed out, some examples could be active storage gauged by IOPS or work or bandwidth per watt of energy per footprint while other storage for idle or inactive data could be looked at on a capacity per energy footprint basis.

What benchmarks or workloads to be used for simulating or measuring work or activity are still being discussed with proposals coming from various sources. For example SNIA GSI TWG are developing measurements and discussing metrics, as have the storage performance council (SPC) and SPEC among others including use of simulation tools such as IOmeter, VMware VMmark, TPC, Bonnie, or perhaps even Microsoft ESRP.

Tenants of Energy Star for Data Center Storage overtime hopefully will include:

  • Reflective of different types, categories, price-bands and storage usage scenarios
  • Measure storage efficiency for active work along with in-active or idle usage
  • Provide insight for both storage performance efficiency and effective capacity
  • Baseline or raw storage capacity along with effective enhanced optimized capacity
  • Easy to use metrics with more in-depth back ground or disclosure information

Ultimately the specification should help IT storage buyers and decision makers to compare and contrast different storage systems that are best suited and applicable to their usage scenarios.

This means measuring work or activity per energy footprint at a given capacity and data protection level to meet service requirements along with during in-active or idle periods. This also means showing storage that is capacity focused in terms of how much data can be stored in a given energy footprint.

One thing that will be tricky however will be differentiating GBytes per watt in terms of capacity, or, in terms of performance and bandwidth.

Here are some links to learn more:

Stay tuned for more on Energy Star for Data Centers, Servers and Data Center Storage.
