Clarifying Clustered Storage Confusion

Clustered storage can be iSCSI, Fibre Channel block based or NAS (NFS or CIFS or proprietary file system) file system based. Clustered storage can also be found in virtual tape library (VTL) including dedupe solutions along with other storage solutions such as those for archiving, cloud, medical or other specialized grids among others.

Recently in the IT and data storage specific industry, there has been a flurry of merger and acquisition (M&A) (Here and here), new product enhancement or announcement activity around clustered storage. For example, HP buying clustered file system vendor IBRIX complimenting their previous acquisition of another clustered file system vendor (PolyServe) a few years ago, or, of iSCSI block clustered storage software vendor LeftHand earlier this year. Another recent acquisition is that of LSI buying clustered NAS vendor ONstor, not to mention Dell buying iSCSI block clustered storage vendor EqualLogic about a year and half ago, not to mention other vendor acquisitions or announcements involving storage and clustering.

Where the confusion enters into play is the term cluster which means many things to different people, and even more so when clustered storage is combined with NAS or file based storage. For example, clustered NAS may infer a clustered file system when in reality a solution may only be multiple NAS filers, NAS heads, controllers or storage processors configured for availability or failover.

What this means is that a NFS or CIFS file system may only be active on one node at a time, however in the event of a failover, the file system shifts from one NAS hardware device (e.g. NAS head or filer) to another. On the other hand, a clustered file system enables a NFS or CIFS or other file system to be active on multiple nodes (e.g. NAS heads, controllers, etc.) concurrently. The concurrent access may be for small random reads and writes for example supporting a popular website or file serving application, or, it may be for parallel reads or writes to a large sequential file.

Clustered storage is no longer exclusive to the confines of high-performance sequential and parallel scientific computing or ultra large environments. Small files and I/O (read or write), including meta-data information, are also being supported by a new generation of multipurpose, flexible, clustered storage solutions that can be tailored to support different applications workloads.

There are many different types of clustered and bulk storage systems. Clustered storage solutions may be block (iSCSI or Fibre Channel), NAS or file serving, virtual tape library (VTL), or archiving and object-or content-addressable storage. Clustered storage in general is similar to using clustered servers, providing scale beyond the limits of a single traditional system—scale for performance, scale for availability, and scale for capacity and to enable growth in a modular fashion, adding performance and intelligence capabilities along with capacity.

For smaller environments, clustered storage enables modular pay-as-you-grow capabilities to address specific performance or capacity needs. For larger environments, clustered storage enables growth beyond the limits of a single storage system to meet performance, capacity, or availability needs.

Applications that lend themselves to clustered and bulk storage solutions include:

  • Unstructured data files, including spreadsheets, PDFs, slide decks, and other documents
  • Email systems, including Microsoft Exchange Personal (.PST) files stored on file servers
  • Users’ home directories and online file storage for documents and multimedia
  • Web-based managed service providers for online data storage, backup, and restore
  • Rich media data delivery, hosting, and social networking Internet sites
  • Media and entertainment creation, including animation rendering and post processing
  • High-performance databases such as Oracle with NFS direct I/O
  • Financial services and telecommunications, transportation, logistics, and manufacturing
  • Project-oriented development, simulation, and energy exploration
  • Low-cost, high-performance caching for transient and look-up or reference data
  • Real-time performance including fraud detection and electronic surveillance
  • Life sciences, chemical research, and computer-aided design

Clustered storage solutions go beyond meeting the basic requirements of supporting large sequential parallel or concurrent file access. Clustered storage systems can also support random access of small files for highly concurrent online and other applications. Scalable and flexible clustered file servers that leverage commonly deployed servers, networking, and storage technologies are well suited for new and emerging applications, including bulk storage of online unstructured data, cloud services, and multimedia, where extreme scaling of performance (IOPS or bandwidth), low latency, storage capacity, and flexibility at a low cost are needed.

The bandwidth-intensive and parallel-access performance characteristics associated with clustered storage are generally known; what is not so commonly known is the breakthrough to support small and random IOPS associated with database, email, general-purpose file serving, home directories, and meta-data look-up (Figure 1). Note that a clustered storage system, and in particular, a clustered NAS may or may not include a clustered file system.

More nodes, ports, memory, and disks do not guarantee more performance for applications. Performance depends on how those resources are deployed and how the storage management software enables those resources to avoid bottlenecks. For some clustered NAS and storage systems, more nodes are required to compensate for overhead or performance congestion when processing diverse application workloads. Other things to consider include support for industry-standard interfaces, protocols, and technologies.

Scalable and flexible clustered file server and storage systems provide the potential to leverage the inherent processing capabilities of constantly improving underlying hardware platforms. For example, software-based clustered storage systems that do not rely on proprietary hardware can be deployed on industry-standard high-density servers and blade centers and utilizes third-party internal or external storage.

Clustered storage is no longer exclusive to niche applications or scientific and high-performance computing environments. Organizations of all sizes can benefit from ultra scalable, flexible, clustered NAS storage that supports application performance needs from small random I/O to meta-data lookup and large-stream sequential I/O that scales with stability to grow with business and application needs.

Additional considerations for clustered NAS storage solutions include the following.

  • Can memory, processors, and I/O devices be varied to meet application needs?
  • Is there support for large file systems supporting many small files as well as large files?
  • What is the performance for small random IOPS and bandwidth for large sequential I/O?
  • How is performance enabled across different application in the same cluster instance?
  • Are I/O requests, including meta-data look-up, funneled through a single node?
  • How does a solution scale as the number of nodes and storage devices is increased?
  • How disruptive and time-consuming is adding new or replacing existing storage?
  • Is proprietary hardware needed, or can industry-standard servers and storage be used?
  • What data management features, including load balancing and data protection, exists?
  • What storage interface can be used: SAS, SATA, iSCSI, or Fibre Channel?
  • What types of storage devices are supported: SSD, SAS, Fibre Channel, or SATA disks?

As with most storage systems, it is not the total number of hard disk drives (HDDs), the quantity and speed of tiered-access I/O connectivity, the types and speeds of the processors, or even the amount of cache memory that determines performance. The performance differentiator is how a manufacturer combines the various components to create a solution that delivers a given level of performance with lower power consumption.

To avoid performance surprises, be leery of performance claims based solely on speed and quantity of HDDs or the speed and number of ports, processors and memory. How the resources are deployed and how the storage management software enables those resources to avoid bottlenecks are more important. For some clustered NAS and storage systems, more nodes are required to compensate for overhead or performance congestion.

Worried about IT M&A, here come the new startups!

Storage I/O trends

Late last year , I did a post (see here) countering the notion that there is a lack of innovation in IT and specifically around data storage. Recently I did a post about a Funeral for Friend, not to mention yesterdays post about Summer marriages.

For those who are concerned about lack of innovation, or, that consolidation will result in just a few big vendors, here’s some food for thought. Those big vendors in addition to growing via internal organic growth, also grow by buying or merging with other vendors. Those other vendors emerge as startups, some grow, blossom and are bought, some make a decent business on their own, some are looking to be bought, some need to be bought, some will see fire sales, liquidation or simply closing their doors and perhaps re-launching as a new company.

With all the M&A activity currently that has taken place, and I’m sure (speculation only ;) ) that there will be plenty more, here’s a short and far from comprehensive list of some startups or companies you may not have heard of yet. There are additional ones who are still in deep stealth, some on the list are still in stealth, yet talking and letting information trickle out, thus only non-NDA information is being shown here. In other words, you can find out about these via publicly available information and sources.

Something that I have noticed and talked with others in the industry about is that this generation of startups, at least for now are taking a far more low-key approach to their launches than in the past. Gone at least for now are the Dot COM era over the top announcements in some cases before there was even a product or shipping for actual customer production deployment scenario. This crop or corps of startups are taking their time leveraging the current economic situation to further incubate their technologies and go to market strategies, not to mention minimizing the amount of over the top VC funding we have seen in the past. Some of these may not appear to be storage related and that would be correct. This list includes those associated with data infrastructure technolgies from servers, to storage to networking, hardware, software and services among othes as a common theme.

Summer Weddings: EMC+Datadomain and HP+IBRIX

Storage I/O trends

Are you friend or family of the bride or groom?

Here’s comes the bride! (Audio)

That’s a question me and Mrs. Schulz were asked recently when we attended a wedding.

Summer months particularly June and August are known as wedding months (Hmmm, more merger & acquisition activity to come?). Summer is a nice time of the year for marriages at least in the U.S. and how ironic that we have already seen two well publicized IT data storage industry unions in the past couple of weeks, not to mention other smaller less publicized ones.

In one case, the California based bride (Datadomain-DDUP) had two courtiers (Massachusetts based EMC and California based NetApp, plus rumors of others). Fortunately one of those had a prenuptial that earned them a cool $57 million for their efforts (NetApp-NTAP) when EMC won the bride. Read more including some of my comments and perspectives among others about EMC, NTAP and DDUP here and here.

Yesterday, on a mid-July Friday, when things are normally quiet, in true wedding industry forum, news was released (here and here) that California based HP announced that it had bought Massachusetts based data and storage management software vendor IBRIX.

That’s a lot of activity involving California and Massachusetts in the past couple of weeks, not to mention the tornado sightings in the vicinity of EMCs Hopington Massachusetts headquarters coincidently around the same time the marriage to DDUP was formerly announced! What’s’ next, Aerosmith is out on tour, perhaps the Del Fuegos or Boston will perform at one of these wedding parties?

Within the data storage industry, publicly traded Datadomain (DDUP) is fairly well known to many for their role in helping to popularize the data footprint impact reduction technique refereed to as de-duplication (e.g. normalization, commonality factoring, intelligent compression, etc.). Adding to the awareness of DDUP was the recent highly public courtship with EMC eventually out-bidding NTAP with a dowry of about $2.1B USD. That type of press coverage and monetary amounts might normally be expected for the likes of a Madonna, Brittney Spears, Michael Jackson-RIP, Paris Hilton, Elizabeth Taylor or other celebrity unions covered by paparazzi with a similar number of attorneys involved.

On the other hand, IBRIX while known to some, is a lessor known entity compared to DDUP having taken a lower profile than even some of their close competitors. However for those who have been following and covering the clustered storage market (see here, here, here, here, here, here, here, here and here ), IBRIX is a well known entity.

IBRIX also has had ties to EMC having been involved in a pre-mari age affair with an reseller arrangement along with being "rumored" ;) to have been involved with ATMOS cloud or policy based storage solution formerly known as "Hulk". IBRIX has also quietly been involved with others like Dell as well as HP in similar to EMC reseller arrangements. Where IBRIX has been positioned is to address high performance, scale out parallel or concurrent clustered file system needs, both big and small I/O, sequential and random data storage and access. For example, in the media/entertainment and other industries along with enabling large Internet providers a bulk (low cost, high capacity) scale-out NAS (NFS & CIFS) option.

One of the reasons that IBRIX has been involved with the likes of EMC, Dell and HP among others is that unlike other vendors such as BlueArc, the once high-flying Isilon, NetApp, Onstor or Panasas, not to mention EMC Cellera NAS , is that those solutions are all bundled with proprietary hardware while IBRIX is software based. Where IBRIX Fusion fits is to enable NAS storage solutions using industry standard hardware (servers and storage) that are capable of being configured for both high performance compute (HPC) along with for low-cost general purpose bulk storage to support Web 2.0, social networking, home directories or on-line archives.

Consequently, and HP or Dell who just happen to sell servers, have had the ability of meeting large scale out and scale up NAS file serving applications by re-selling IBRIX installed on their servers or blade servers with either their own entry to mid-range lower cost, high performance and high capacity storage along with that of 3rd party vendors.

Ironically one of IBRIX’s competitors in the software NAS solution market was and remains PolyServe, software that HP acquired a couple of years ago to create their own scale out NAS solution (e.g. EFS). Other software based solutions include among others Lustre (Sun), CXFS (SGI), EMC ATMOS (I’m sure some will argue this is not scale out or NAS, will leave it at that for now) ;) not to mention those from IBM, Microsoft, Quantum (also re-sold by HP) or Symantec.

What does HP get with IBRIX?

Simple, the ability to own the IP (intellectual proprietary) that one of their competitors had been "rumored" to have been working with at one point, IP that their competitors had been reselling like themselves.

Thus HP gets more software IP that can and has been sold along with their hardware such as the Proliant servers and blade servers giving their customers choice, similar to what HP and other vendors do with their open servers. For example, HP had the ExDS9000 extreme storage system built on a blade server with high density, low cost, high capacity HP storage (e.g. HP Modular Disk System 600, HP MSA or even EVA).

This makes for a nice solution for bulk on-line and near-line storage applications where the emphasis is not as much on performance, rather massive scalability for storing on-line documents, archives, videos, images and other unstructured content which is where there is a lot of growth activity. The challenge is that the ExDS9x00 has only been available with the HP PolyServe software which works good for some environments, yet, for others, the clustered file system scale out capabilities of IBRIX were deployed.

With the addition of IBRIX, HP now should be able to provide their customers and prospects the choice of software to meet specific needs while maintaining an HP footprint, that is both hardware, software and services. HP has several different storage software stacks that they now own (e.g. Lefthand for clustered iSCSI, PolyServe for NFS/CIFS NAS, IBRIX for Clustered File system scale out NAS) not to mention those that it OEMS including among others Bycast (Medical Archive System) that is also OEM’d by IBM as their Medical Grid combined with IBM SOFS, Quantum StorNext and Microsoft Windows Storage Server and Sepaton (VTL and Dedupe) to name a few.

Do I think this was a good move by HP?

Yes as it gives them control over IP that they had been reselling as had some of their competitors who left IBRIX to HP to grab up. HP now has the IP which they can package with their hardware similar to how they have been doing, and giving customers choices to align the right hardware and software technology to the task at hand.

Whether it be Bycast for medical archiving, PolyServe or IBRIX for scale out NAS, Lefthand for clustered iSCSI, Sepaton for VTL and dedupe, Microsoft, Quantum StorNext for shared block storage serving or any of the other software packages HP offers with their industry standard servers, the customer has options.

For IBRIX customers and prospects, this move will give them a boost in a confidence that their decisions and investments are safe.

Ironically, vendors like Symantec with their Scaleable File Serving (SFS) clustered NAS solution that is also software based and runs on anyone’s open servers including those from HP gets a potential shot in the arm with HP validating the model and approach for bulk-storage and clustered NAS (Oh Mr. Salem, Mr. Dell is holding on Line 1, Mr. Chambers is on line 2 and Mr. Ellison on line 3 ;) )

Who’s going to be at the alter next? IMHO, I would keep an eye on (and this all just pure speculation) Bycast, Symantec, EMLX (Broadcom was a wake up call), Quantum, Sepaton, STEC, StorMagic, or ACS, maybe even 3PAR among other possibilities (think outside of the lines). I would not rule out a major game changer such as someone buying NetApp or the likes of an HP buying an EMC or Oracle buying a CSC, maybe even a CSCO buying someone like NTAP, how about Oracle buying NTAP and putting some attorneys out of work, not to mention, who will MSFT hook up with? Anything is possible as we have seen and traditional M&A wisdom is out the window.

Have fun at the next wedding you attend, go easy on the cake and wedding punch, especially if you will be doing any dancing (please, no You tube videos of the chicken dance) and be careful throwing rice or other items.

Ok, nuff said.

Shifting from energy avoidance to energy efficiency

Storage I/O trends

I’m continually amazed at the number of people in the IT industry from customers to vendors, vars to media and even analysts who associate Green IT with and only with reducing carbon footprints. I guess I should not be surprised given the amount of rhetoric around Green and carbon both in the IT industry as well as in general resulting in a Green Gap.

The reality as I have discussed in the past is that Green IT while addressing carbon footprint topics, is really more about efficiency and optimization for business economic benefits that also help the environment. From a near-term tactical perspective, Green IT is about boosting productivity and enabling business sustainability during tough economic times, doing more with less, or, doing more with what you have. On a strategic basis, Green IT is about continued sustainability while also improving top and bottom line economics and repositioning IT as a competitive advantage resource.

There is a lot of focus on energy avoidance, as it is relatively easy to understand and it is also easy to implement. Turning off the lights, turning off devices when they are not in use, enabling low-power, energy-savings or Energy Star® (now implemented for servers with storage being a new focus) modes are all means to saving or reducing energy consumption, emissions, and energy bills.

Ideal candidates for powering down when not in use or inactive include desktop workstations, PCs, laptops, and associated video monitors and printers. Turning lights off or implementing motion detectors to turn lights off automatically, along with powering off or enabling energy-saving modes on general-purpose and consumer products has a significant benefit. New generations of processors such as the Intel Xeon 5xxx or 7xxx series (formerly known as Nehalem) provide the ability to boost performance when needed, or, go into various energy conservation modes when possible to balance performance, availability and energy needs to applicable service requirements, a form of intelligent power management.

In Figure 1 are shown four basic approaches (in addition to doing nothing) to energy efficiency. One approach is to avoid energy usage, similar to following a rationing model, but this approach will affect the amount of work that can be accomplished. Another approach is to do more work using the same amount of energy, boosting energy efficiency, or the complement—do the same work using less energy.

Tiered Storage
Figure 1 the Many Faces of Energy Efficiency (Source: “The Green and Virtual Data Center” (CRC)

The energy efficiency gap is the difference between the amount of work accomplished or information stored in a given footprint and the energy consumed. In other words, the bigger the energy efficiency gap, the better, as seen in the fourth scenario, doing more work or storing more information in a smaller footprint using less energy.

Given the shared nature of their use along with various intersystem dependencies, not all data center resources can be powered off completely. Some forms of storage devices can be powered off when they are not in use, such as offline storage devices or mediums for backups and archiving. Technologies such as magnetic tape or removable hard disk drives that do not need power when they are not in use can be used for storing inactive and dormant data.

Avoiding energy use can be part of an approach to address power, cooling, floor space and environmental (PCFE) challenges, particularly for servers, storage, and networks that do not need to be used or accessible at all times. However, not all applications, data or workloads can be consolidated, or, powered down due to performance, availability, capacity, security, compatibility, politics, financial and many other reasons. For those applications that cannot be consolidated, the trick is to support them in a more efficient and effective means.

Simply put, when work needs to be done or information needs to be stored or retrieved or data moved, it should be done so in the most energy-efficient manner aligned to a given level of service which can mean leveraging faster, higher performing resources (servers, storage and networks) to get the job done fast resulting in improved productivity and efficiency.

Tiering is an approach that applies to servers, storage, and networks as well as data protection. For example, tiered servers include large frame or mainframes, rack mount as well as blades with various amounts of memory, I/O or expansion slots and number of processor cores at different speeds. Tiered storage includes different types of mediums and storage system architectures such as those shown in figure 2. Tiered networking or tiered access includes 10Gb and 1Gb Ethernet, 2/4/8 Gb Fibre Channel, Fibre Channel over Ethernet (FCoE), iSCSI, NAS and shared SAS among others. Tiered data protection includes various technologies to meet various recovery time objectives (RTO) and recovery point objectives (RPO) such as real-time synchronous mirroring with snapshots, to periodic backup to disk or tape among other approaches, techniques and technologies.

Technology alignment (Figure 2), that is aligning the applicable type of storage or server resource and devices to the task at hand to meet application service requirements is essential to archiving an optimized and efficient IT environment. For example, for very I/O intensive active data as shown in figure 2, leveraging ultra fast tier-0 high-performance SSD (FLASH or RAM) storage, or for high I/O active data, tier-1 fast 15.5K SAS and Fibre Channel storage based systems would be applicable.

For active and on-line data, that’s where energy efficiency in the form of fast disk drives including RAM SSD or FLASH SSD (for reads, writes are another story) and in particular fast 15.5K or 10K FC and SAS energy efficient disks and their associated storage systems come into play. The focus for active data and storage systems should be around more useful work per unit of energy consumed in a given footprint. For example, more IOPS per watt, more transactions per watt, more bandwidth or video streams per watt, more files or emails processed per watt.

Tiered Storage

Figure 2 Tiered Storage: Balancing Performance, Availability, Capacity and Energy to QoS (Source: “The Green and Virtual Data Center” (CRC)

For low-performance, low activity applications where the focus is around storing as much data as possible with the lowest cost including for disk to disk based backup, slower high capacity SATA based storage systems are the fit (lower right in figure 2). For long-term bulk storage to meet archiving, data retention or other retention needs as well as storing large monthly full backups or long term data preservation, tape remains the ticket for large environments with the best combination of performance, availability capacity and energy efficiency and cost per footprint.

General approaches to boost energy efficiency include:

  • Do more work using the same or less amount of power and subsequently cooling
  • Leverage faster processors/controllers that use the same or less power
  • Apply applicable RAID level to application and data QoS requirements
  • Consolidate slower storage or servers to a faster, more energy-efficient solution
  • Use faster disk drives with capacity boost and that draw less power
  • Upgrade to newer, faster, denser, more energy-efficient technologies
  • Look beyond capacity utilization; keep response time and availability in mind
  • Leverage IPM, AVS, and other techniques to vary performance and energy usage
  • Manage data both locally and remote; gain control and insight before moving problems
  • Leverage a data footprint reduction strategy across all data and storage tiers
  • Utilize multiple data footprint techniques including archive, compression and de-dupe
  • Reduce data footprint impact, enabling higher densities of stored on-line data

Find a balance between energy avoidance and energy efficiency, consolidation and business enablement for sustainably, hardware and software, best practices including policy and producers, as well as leveraging available financial rebates and incentives. Addressing green and PCFE issues is a process; there is no one single solution or magic formula.

Efficient and Optimized IT Wheel of Oppourtunity

Figure 3 Wheel of Opportunity – Various Techniques and Technologies for Infrastructure Optimization (Source: “The Green and Virtual Data Center” (CRC)

Instead, leverage a combination of technologies, techniques, and best practices to address various issues and requirements is needed (Figure 3). Some technologies and techniques include among others infrastructure resource management (IRM), data management, archiving (including for non-compliance), and compression (on-line and off-line, primary and secondary) as well as de-dupe for backups, space saving snapshots, and effective use of applicable raid levels.

Green washing and green hype may fade away, however power, cooling, footprint, energy (PCFE) and related issues and initiatives that enable IT infrastructure optimization and business sustainability will not fade away. Addressing IT infrastructure optimization and efficiency is thus essential to IT and business sustainability and growth in an environmentally friendly manner which enables shifting from talking about green to being green and efficient.

Storage Decisions Spring 2009 Sessions Update

StorageDecisions Logo

The conference lineup and details for the Spring 2009 Storage Decisions event (June 1st and 2nd) in Chicago is coming together including two talks/presentations that I will be doing. One will be in Track 2 (Disaster Recovery) titled "Server Virtualization, Business Continuance and Disaster Recovery" and the other in Track 6 (Management/Executive) titled "The Other Green — Storage Efficiency and Optimization" with both sessions leveraging themes and topics from my new book "The Green and Virtual Data Center" (CRC).

Track 2: Disaster Recovery
Server Virtualization, Business Continuance and Disaster Recovery
Presented by Greg Schulz, Founder and Senior Analyst, StorageIO
Server virtualization has the potential to bring sophisticated business continuance (BC) and disaster recovery (DR) techniques to organizations that previously didn’t have the means to adopt them. Likewise, virtualized as well as cloud environments need to be included in a BC/DR plan to enable application and data availability. Learn tips and tricks on building an accessible BC/DR strategy and plan using server virtualization and the storage products that enable efficient, flexible green and virtual data centers.

Topics include:
* Cross technology domain data protection management
* Tiered data protection to stretch your IT budget dollar
* What’s needed to enable BC/DR for virtualized environments
* How virtualization can enable BC/DR for non-virtualized environments
* General HA, BC/DR and data protection tips for virtual environments

Track 6: Management/Executive
The Other Green — Storage Efficiency and Optimization
Throw out the "green“: buzzword, and you’re still left with the task of saving or maximizing use of space, power, and cooling while stretching available IT dollars to support growth and business sustainability. For some environments the solution may be consolation while others need to maintain quality of service response time, performance and availability necessitating faster, energy efficient technologies to achieve optimization objectives. To accomplish these and other related issues, you can turn to the cloud, virtualization, intelligent power management, data footprint reduction and data management not to mention various types of tiered storage and performance optimization techniques. The session will look at various techniques and strategies to optimize either on-line active or primary as well as near-line or secondary storage environment during tough economic times, as well as to position for future growth, after all, there is no such thing as a data recession!

Topics include:
* Energy efficiency (strategic) vs. energy avoidance (tactical)
* Optimization and the need for speed vs. the need for capacity
* Metrics and measurements for management insight
* Tiered storage and tiered access including SSD, FC, SAS and clouds
* Data footprint reduction (archive, compress, dedupe) and thin provision
* Best practices, financial incentives and what you can do today

See you in Chicago in June if not before then. Learn more about other upcoming events and activities on the StorageIO events page.

March and Mileage Mania Wrap-up

Today’s flight to Santa Ana (SNA) Orange County California for an 18 hour visit marks my 3rd trip to the left coast in the past four weeks that started out with a trip to Los Angeles. The purpose of today’s trip is to deliver a talk around Business Continuance (BC) and Disaster recovery (DR) topics for virtual server and storage environments along with related data transformation topics themes, part of a series of on-going events.

Planned flight path from MSP to SNA, note upper midwest snow storms. Thanks to Northwest Airlines, now part of Delta!

This is a short trip to southern California in that I have to be back in Minneapolis for a Wednesday afternoon meeting followed by keynoting at an IT Infrastructure Optimization Seminar downtown Minneapolis Thursday morning. Right after Thursday morning session, its off to the other coast for some Friday morning and early afternoon sessions in the Boston area, the results of which I hope to be able to share with you in a not so distant future posting.

Where has March gone? Its been a busy and fun month out on the road with in-person seminars, vendor and user group events in Minneapolis, Los Angles, Las Vegas, Milwaukee, Atlanta, St. Louis, Birmingham, Minneapolis for CMG user group, Cincinnati and Orange County not to mention some other meetings and consulting engagements elsewhere including participating in a couple of webcast and virtual conference/seminars while on the road. Coverage and discussion around my new book "The Green and Virtual Data Center" (CRC) continues expand, read here to see what’s being said.

What has made the month fun in addition to traveling around the country is the interaction with the hundreds of IT professionals from organizations of all size hearing what they are encountering, what their challenges are, what they are thinking, and in general what’s on their mind.

Some of the common themes include:

  • There’s no such thing as a data recession, however the result is doing more with less, or, with what you have
  • Confusion abounds around green hype including carbon footprints vs. core IT and business issues
  • There is life beyond consolidation for server and storage virtualization to enable business agility
  • Security and encryption remain popular topic as does heterogeneous and affordable key management
  • End to end IT resource management for virtual environments is needed that is scalable and affordable
  • Performance and quality of service can not be sacrificed in the quest to drive up storage utilization
  • Clouds, SSD (FLASH), Dedupe, FCoE and Thin Provisioning among others are on the watch list
  • Tape continues to be used complimenting disks in tiered storage environments along with VTLs
  • Dedupe continues to be deployed and we are just seeing the very tip of the ice-berg of opportunity
  • Software licensing cost savings or reallocation should be a next step focus for virtual environments
  • Now, for a bit of irony and humor, overheard was a server sales person talking to a storage sales person comparing notes on how they are missing their forecasts as their customers are buying fewer servers and storage now that they are consolidating with virtualization, or using disk dedupe to eliminate disk drives. Doh!!!

    Now if those sales people can get their marketing folks to get them the play book for virtualization for business agility, improving performance and enabling business growth in an optimized, transformed environment, they might be able to talk a different story with their customers for new opportunities…

    What’s on deck for April? More of the same, however also watch and listen for some additional web based content including interviews quotes and perspectives on industry happenings, articles, tips and columns, reports, blogs, videos, podcasts, webcasts and twitter activity as well as appearances at events in Boston, Chicago, New Jersey and Providence among other venues.

    To all of those who came out to the various events in March, thank you very much and look forward to future follow-up conversations as well as seeing you at some of the upcoming future events.

    Cheers gs

    Odds and Ends – Getting Caught Up, News and Other Updates

    This post is a collection of various odds and ends, news and updates as Im getting caught up on some things.

    Here’s a link to the first of what will be a series of up-coming short articles appearing at Byte and Switch related to my new book "The Green and Virtual Data Center" (CRC). The first installment appeared recently and is titled "Green IT & the Green Gap" and the theme of the installment is that in going green, you enable a business to grow, diversify, and expand its use of IT, all of which have economic benefits. Learn more about the green gap here.

    Also over at Byte and Switch, Paul Travis recently did an article "Going Green & the Economic Downturn" that takes a look the shifting green focus to that around economic and cost cutting opportunities during current finical turmoil. Also on the Green front, Drew Robb has an interesting article talking about server and IT data center "Green IT Myths vs. Realities" appearing in ServerWatch. Another new green and economic sustainability for IT data center article can be found over at Greener Computing with a link here. While on the topic of my new book, writer and blogger, Heather Clancy has some comments about "The Green and Virtual Data Center" (CRC) over at ZDNET. Dave Simpson of InfoStor fame has a blog post as well that mentions my new book, check it out here. Also, check out this posting over at Datacenterlinks blogsite as well as a post over at Green Data Center blog site.

    Meanwhile inventory and book availability continue to improve at Amazon.com and other venues around the world as back-logs from pre-orders and initial book sales resulted in some sell-out or initial limited availability. My publisher CRC informs me that plenty of books are flowing out and into the distribution supply chain to meet risking demand including bulk and special promotional and educational sales. Thanks to all of you have obtained copies of my new book, drop me a note with your comments and feedback when you get a chance. Also watch for additional book news, reviews, reports and other programs to be announced over the coming weeks.

    For addressing data center bottlenecks, on the tiered storage and Solid State Device (SSD) front, that’s for both RAM and FLASH based, here’s an article over at Processor.com worth a look at. Here are a couple of other recent articles over at Processor.com addressing small form factor servers and refurbished servers, as well as freeing up data center space. Steve Kovosky has an interesting blog post over at Virtualization Conversation about Virtualization: Life Beyond Consolidation building on a previous blog posting I did a few weeks back pertaining to server and storage virtualization trends and directions. Here’s a recent article by Paul Shread over at Enterprise Storage Forum about T10 Object Storage Devices (OSD) and their current status or lack of progress including Sun’s shifting focus.

    Speaking of data protection for physical and virtual environments, tape, data protection management, monitoring and managing IT resource effectiveness not to mention stretching your IT budget dollar, here’s a link to an article over at CTR in which yours truly provides some commentary. Also on the data protection theme, Walaika Haskins over at TechNewsWorld has a good article about "Figuring Out the Best Way to Stash Your Data". Data dedupe continues to be a popular topic for discussion and Cindy Waxer recently wrote an article appearing at Inc. Technology pertaining to Dedupe and Disaster Recovery (DR) and Business Continence (BC). Also on the dedupe front, here’s a industry trends and perspective solutions brief over on the EMC site pertaining to policy based data dedupe deployment (don’t worry, its not a data dedupe debate document, however I suppose some of the Drs’ and Divas’ of Dedupe may see it that way which will give them something to debate ;) ) with a focus around when to use which type or mode of dedupe processing to meet different applications requirements (may require registration, however its free, the document that is).

    Technorati tags: Trends

    Is There a Data and I/O Activity Recession?

    Storage I/O trends

    With all the focus on both domestic and international economic woes and discussion of recessions and depressions and possible future rapid inflation, recent conversations with IT professionals from organizations of all size across different industry sectors and geographies prompted the question, is there also a data and I/O activity recession?

    Here’s the premise, if you listen to current economic and financial reports as well as employment information, the immediate conclusion is that yes, there should also be an I recession in the form of contraction in the amount of data being processed, moved and stored which would also impact I/O (e.g. DAS,, LAN, SAN, FAN or NAS, MAN, WAN) networking activity as well. After all, the server, storage, I/O and networking vendors earnings are all being impacted right?

    As is often the case, there is more to the story, certainly vendor earnings are down and some vendors are shipping less product than during corresponding periods from a year or more ago. Likewise, I continue to hear from both IT organizations, vars and vendors of lengthened sales cycles due to increased due diligence and more security of IT acquisitions meaning that sales and revenue forecasts continue to be very volatile with some vendors pulling back on their future financial guidance.

    However, does that mean fewer servers, storage, I/O and networking components not to mention less software is being shipped? In some cases there is or has been a slow down. However in other cases, due to pricing pressures, increased performance and capacity density where more work can be done by fewer devices, consolidation, data footprint reduction, optimization, virtualization including VMware and other techniques, not to mention a decrease in some activity, there is less demand. On the other hand, while some retail vendors are seeing their business volume decrease, others such as Amazon are seeing continued heavy demand and activity.

    Been on a trip lately through an airport? Granted the airlines have instituted capacity management (e.g. capacity planning) and fleet optimization to align the number of flights or frequency as well as aircraft type (tiering) to the demand. In some cases smaller planes, in other cases larger planes, for some more stops at a lower price (trade time for money) or in other cases shorter direct routes for a higher fee. The point being is that while there is an economic recession underway, and granted there are fewer flights, many if not most of those flights are full which means transactions and information to process by the airlines reservations and operational as well as customer relations and loyalty systems.

    Mergers and acquisitions usually mean a reduction or consolidation of activity resulting in excess and surplus technologies, yet talking with some financial services organizations, over time some of their systems will be consolidated to achieve operating efficiency and synergies, near term, in some cases, there is the need for more IT resources to support the increased activity of supporting multiple applications, increased customer inquiry and conversion activity.

    On a go forward basis, there is the need to support more applications and services that will generate more I/O activity to enable data to be moved, processed and stored. Not to mention, data being retained in multiple locations for longer periods of time to meet both compliance and non regulatory compliance requirements as well as for BC/DR and business intelligence (BI) or data mining for marketing and other purposes.

    Speaking of the financial sector, while the economic value of most securities is depressed, and with the wild valuation swings in the stock markets, the result is more data to process, move and store on a daily basis, all of which continues to place more demand on IT infrastructure resources including servers, storage, I/O networking, software, facilities and the people to support them.

    Dow Jones Trading Activity Volume
    Dow Jones Trading Activity Volume (Courtesy of data360.org)

    For example, the amount of Dow Jones trading activity is on a logarithmic upward trend curve in the example chart from data360.org which means more transactions selling and buying. The result of more transactions is that there are also an increase in the number of back-office functions for settlement, tracking, surveillance, customer inquiry and reporting among others activities. This means that more I/Os are generated with data to be moved, processed, replicated, backed-up with additional downstream activity and processing.

    Shifting gears, same things with telephone and in particular cell phone traffic which indirectly relates on IT systems particular for support email and other messaging activity. Speaking of email, more and more emails are sent every day, granted many are spam, yet these all result in more activity as well as data.

    What’s the point in all of this?

    There is a common awareness among most IT professionals that there is more data generated and stored every year and that there is also an awareness of the increased threats and reliance upon data and information. However what’s either not as widely discussed is the increase in I/O and networking activity. That is, the space capacity often gets talked about, however, the I/O performance, response time, activity and data movement can be forgotten about or its importance to productivity diminished. So the point is, keep performance, response time, and latency in focus as well as IOPS and bandwidth when looking at, and planning IT infrastructure to avoid data center bottlenecks.

    Finally for now, what’s your take, is there a data and/or I/O networking recession, or is it business and activity as usual?

    Ok, nuff said.

    On The Road Again: An Update

    A while back, I posted about a busy upcoming spring schedule of activity and events, and then a few weeks ago, posted an update, so this can be considered the latest "On The Road Again" update. While the economy continues to be in rough condition and job reductions or layoffs continuing, or, reduction in hours or employees being asked to take time off without pay or to take sabbaticals, not to mention the race to get the economic stimulus bill passed, for many people, business and life goes on.

    Airport parking lots have plenty of cars in them, airplanes while not always full, are not empty (granted there has been some fleet optimization aka aligning capacity to best suited tier of aircraft and other consolidation or capacity improvements). Many organizations cutting back on travel and entertainment (T&E) spending, either to watch the top and bottom line, avoid being perceived or seen on the news as having employees going on junkets when they may in fact being going to conferences, seminars, conventions or other educational and related events to boost skills and seek out ways to improve business productivity.

    One of the reason that I have a busy travel schedule in addition to my normal analyst and consulting activities is that many events and seminars are being scheduled close to, or in the cities where IT professionals are located who might otherwise have T&E restrictions or other constraints from traveling to industry events, some of which are or will be impacted by recent economic and business conditions.

    Last week I was invited to attend and speak at the FujiFilm Executive Seminar, no private jets were used or seen, travel was via scheduled air carriers (coach air-fare). FujiFilm has a nice program for those interested in or involved with tape whether for disk to tape backup, disk to disk to tape, long term archive, bulk storage and other scenarios involving the continued use and changing roles of tape as a green data storage medium for in-active or off-line data. Check out FujiFilm TapePower Center portal.

    This past week I was in the big "D", that’s Dallas Texas to do another TechTarget Dinner event around the theme of BC/DR, Virtualization and IT optimization. The session was well attended by a diverse audience of IT professionals from around the DFW metroplex. Common themes included discussions about business and economic activity as well as the need to keep business and IT running even when budgets are being stretched further and further. Technology conversations included server and storage virtualization, tiered storage including SSD, fast FC and SAS disk drives, lower performance high capacity "fat" disk drives as well as tape not to mention tiered data protection, tiered servers and other related items.

    The Green Gap continues to manifest itself in that when asked, most people do not have Green IT initiatives, however, when asked they do have power, cooling, floor-space, environmental (PCFE) or business economic sustainability concerns, aka, the rest of the Green story.

    While some attendees have started to use some new technologies including dedupe technology, most I find are still using a combination of disk and tape with some considering dedupe for the future for certain applications. Other technologies and trends being watched, however also ones with concerns as to their stability and viability for enterprise use include FLASH based SSD, Cloud computing and thin provisioning among others. Common themes I hear from IT professionals are that these are technologies and tools to keep an eye on, or, use on a selective basis and are essentially tiered resources to have in a tool box of technologies to apply to different tasks to meet various service requirements. Hopefully the Cowboys can put a fraction of the amount of energy and interest into and improving their environment that the Dallas area IT folks are applying to their environments, especially given the strained IT budgets vs. the budget that the Cowboys have to work with for their player personal.

    I always find it interesting when talking to groups of IT professionals which tend to be enterprise, SME and SMB hearing what they are doing and looking at or considering which often is in stark contrast to some of the survey results on technology adoption trends one commonly reads or hears about. Hummm, nuff said, what say you?

    Hope to see you at one of the many upcoming events perhaps coming to a venue near you.

    RAID data protection remains relevant

    Storage I/O trends

    RAID (Redundant Array of Idle/Independent Disks) has evolved significantly since the original RAID white paper from the University of California Berkeley (Patterson, Gibson & Katz) was published 20 some years ago and in many cases is taken for granted today. There is also debate as to whether RAID is still relevant and practical given the continued increase amounts of data that needs to be protected.

    RAID Examples from www.thegreenandvirtualdatacenter.com
    Sample of some common RAID levels, general characteristics, caveat and benefits

    RAID remains relevant today, granted, RAID continues to evolve as do the many variations including distributed and hybrid data protection schemes. Dave Raffo over at SearchStorage has a nice article on "The evolution of RAID data protection" with comments from me. Have a look at the Dave’s article (as well as here) along with some of the comments and thoughts from myself and others.

    Ok, nuff said.

    Server Storage I/O Network Virtualization Whats Next?

    Server Storage I/O Network Virtualization Whats Next?
    Server Storage I/O Network Virtualization Whats Next?
    Updated 9/28/18

    There are many faces and thus functionalities of virtualization beyond the one most commonly discussed which is consolidation or aggregation. Other common forms of virtualization include emulation (which is part of enabling consolidation) which can be in the form of a virtual tape library for storage to bridge new disk technology to old software technology, processes, procedures and skill sets. Other forms of virtualization functionality for life beyond consolidation include abstraction for transparent movement of applications or operating systems on servers, or data on storage to support planned and un-planned maintenance, upgrades, BC/DR and other activities.

    So the gist is that there are many forms of virtualization technologies and techniques for servers, storage and even I/O networks to address different issues including life beyond consolidation. However the next wave of consolidation could and should be that of reducing the number of logical images, or, the impact of the multiple operating systems and application images, along with their associated management costs.

    This may be easier said than done, however, for those looking to cut costs even further than from what can be realized by reducing physical footprints (e.g. going from 10 to 1 or from 250 to 25 physical servers), there could be upside however it will come at a cost. The cost is like that of reducing data and storage footprint impacts with such as data management and archiving.

    Savings can be realized by archiving and deleting data via data management however that is easier said than done given the cost in terms of people time and ability to decide what to archive, even for non-compliance data along with associated business rules and policies to be defined (for automation) along with hardware, software and services (managed services, consulting and/or cloud and SaaS).

    Remember The Alamo

    Yesterday I made a quick trip down to San Antonio Texas (SAT) to do a keynote talk about "BC/DR and Virtual Environments" along with a sprinkling of IT effieincy aka Green; consolidation, power, cooling, footprint, data management and cloud topics mixed in the discussion. The dinner event was put on by TechTarget with the local host being Mobius (not to be confused with Moby, the artist). Mobius is a Texas value added reseller (VAR) and the event took place at Morton’s near the river walk in downtown SAT. This was my second trip to SAT in about two months have done a morning seminar talk about the "Wide World of Archiving – Life beyond Compliance" back in October, also downtown SAT.

    It was a great event with a lively and interesting audience who provide good feedback and conversation sharing their experiences, concerns, issues and what they are looking at or for.

    Some general take away’s that I have from talking with the IT folks who were in attendance at the event include:

  • Do you homework and due diligence with regard to using VCBs for VMware backups
  • Pay attenion to the details when re-architecting and updating data protection for virtual environments
  • iSCSI and FC as well as FCoE all have different roles and places now and into the future for virtual environments
  • Concern about clouds, they are interesting, are a tiered resource to compliment other resources
  • Cloud services need to be part of BC/DR including in plans to isolate against disruptions such what occurred with Amazon and others
  • Not all servers can be consolidated due to different reasons and issues
  • Virtualization platforms (software and appliance or storage system based) can be used for replication, migration and consolidation
  • Virtual tape libraries are being adopted while tape usage continues
  • Discussion around different tiers of storage, tiered access (e.g. iSCSI, FC, FCoE, IBA, NAS, etc) and tiered data protection
  • A common theme is doing more with less, maintaining service levels and support business growth
  • Now on a different note, from technology and trends to travel.

    If you travel enough for business like I have had, you know that its not all jet set lifestyle like people think or assume, in fact many times what I get to see of a city or venue is the view from window of a car or train on the way from an airport to a venue, a hotel and sometimes a dinner event. However now and then, even on quick trips like yesterdays where I was in SAT for 15 hours, opportunities exist to get out even if its for just a moment and take in a site or two, see some of the city or area. Last night was an example of getting a chance to see something interesting when I walked the 7-8 blocks from the venue (I had gone directly from the airport to Mortons).

    Walking back to my hotel (it was a nice evening for a walk) last night, I walked around and near the river walk and low and behold, I stopped, turned and looked and there it was, the Alamo (see photo below taken from my cell phone) in all its splendor. It actually looks a lot smaller than what I thought it would look like, however it was fun to do some inadvertent site seeing before an early morning flight home.

    The Alamo
    Remember the Alamo via Greg’s Cell Phone Camera 12/10/08

    Now lets put travel into perspective here a bit.

    When I woke up yesterday morning it was 3F at home in Stillwater, by time I got to the airport it was a balmy 9F, by mid afternoon when I arrived in SAT and stood in the taxi line, it was a down right tropical in the mid 50s F. This morning when I woke up around 5:30AM for my early morning flight home, it was a cool 35F in SAT with a forecast of getting back up into the 50s (F) today while it was a pleasant 13F when I arrived back at my office early afternoon, the fun of traveling!

    Thanks to everyone who came out to last nights event and it was great to have had a chance to meet and visit with you, hopefully next time we will have more time for follow-up questions, however feel free to drop me a note. Also thanks too the Techtarget, Mobius and Mortons folks for putting a great event together, and, remember the Alamo and if you have not been there, check it and the river walk out!

    Cheers gs
