Cloud and Virtual Data Storage Networking

For those who have read any of my previous posts, seen some of my articles, news letters, videos, pod casts, web casts or in person appearances you may have heard that I have a new book coming out this summer.

Here in the northern hemisphere its summer (well technically the solstice is just around the corner) and in Minnesota the ice (from the winter) is off the lakes and rivers. Granted, there is some ice floating that fell out of coolers for keeping beverages cool. This means that it is also fishing (and catching) season on the Scenic St. Croix River.

Karen of Arcola catches first fish of 2011 season, St. Croix river, stripe bassGreg showing his first catch of the 2011 season, St. Croix walleye aka Walter or Wanda

FTC disclosures (and for fun): Karenofarcola is wearing a StorageIO baseball cap and Im wearing a cap from a vendor marketing person who sent several as they too enjoy fishing and boating. Funny thing about the cap, all of the river rats and fishing people think it is from the people who make rod reels instead of solutions that go around tape and disk reels. Note, if you feel compelled to send me baseball caps, send at least a pair so there is a backup, standby, spare or extra one for a guest. The mustang survival jacket that Im wearing with the Seadoo logo is something I bought myself. I did get a discount however since there was a Seadoo logo on it and I used to have Seadoo jet boats. Btw, that was some disclosure fun and humor!

Ok, enough of the fun stuff, lets get back to the main theme of this post.

My new book which is the third in a series of solo projects including Resilient Storage Networks: Designing Flexible Scalable Data Infrastructures (Elsevier) and The Green and Virtual Data Center (CRC).

While the official launch and general availability will be later in the summer, following are some links and related content to give you advance information about the new book.

Dude, is Dell going to buy Brocade?

Some IT industry buzz this week is around continued speculation (or here) of who will Dell buy next and will it be Brocade.

Brocade was mentioned as a possible acquisition by some in the IT industry last fall after Dell stepped back from the 3PAR bidding war with HP. Industry rumors or speculations are not new involving Dell and Brocade some going back a year or more (or here or here).

Dell

Last fall I did a blog post commenting that I thought Dell would go on to buy someone else (turned out to be Compellent and Insight One). Those acquisitions by Dell followed their purchases of companies including Scalent, Kace, Exanet, Perot, and Ocarina among others. In that post, I also commented that I did not think (at least at that time) that Brocade would be a likely or good fit for Dell given their different business models, go to market strategy and other factors.

Dell is clearly looking to move further up into the enterprise space which means adding more products and routes to market of which one is via networking and another involves people with associated skill sets. The networking business at Dell has been good for them along with storage to complement their traditional server and workstation business, not to mention their continued expansion into medical, life science and healthcare related solutions. All of those are key building blocks for moving to cloud, virtual and data storage networking environments.

Dell has also done some interesting acquisitions around management and service or workflow tools with Scalent and Kace not to mention their scale out NAS file system (excuse me, big data) solutions via Exanet and data footprint reduction tools with Ocarina, all of which have plays in the enterprise, cloud and traditional Dell markets.

But what about Brocade?

Is it a good fit for Dell?

Dell certainly could benefit from owning Brocade as a means of expanding their Ethernet and IP businesses beyond OEM partnerships, like HP supplementing their networking business with 3COM and IBM with Blade networks.

However, would Dell acquiring Brocade disrupt their relationships with Cisco or other networking providers?

If Dell were to make a bid for Brocade, would Huawei (or here) sit on the sidelines and watch or jump in the game to stir things up?

Would Cisco counter with a deal Dell could not refuse to tighten their partnership at different levels perhaps even involving something with the UCS that was discussed on a recent Infosmack episode?

How would EMC, Fujitsu, HDS, HP, IBM, NetApp and Oracle among others, all of who are partners with Brocade respond to Dell now becoming their OEM supplier for some products?

Would those OEM partnerships continue or cause some of those vendors to become closer aligned with Cisco or others?

Again the question, will Huawei sit back or decide to enter the market on a more serious basis or continue to quietly increase their presences around the periphery?

Brocade could be a good fit for Dell giving them a networking solution (both Ethernet via the Foundry acquisition along with Fibre Channel and Fibre Channel over Ethernet (FCoE)) not to mention many other pieces of IP including some NAS and file management tools collecting dust on some Brocade shelf somewhere. What Dell would also get is a sales force that knows how to sell to OEMs, the channel and to enterprise customers, some of whom are networking (Ethernet or Fibre Channel) focused, some who have broader diverse backgrounds.

While it is possible that Dell could end up with Brocade along with a later bidding battle (unless others just let a possible deal go as is), Dell would find itself in new and unfamiliar waters similar to Brocade gaining its feet moving into the Ethernet and IP space after having been comfortable in the Fibre Channel storage centric space for over a decade.

While the networking products would be a good fit for Dell assuming that they were to do such a deal, the diamond in the rough so to speak could be Brocade channel, OEM and direct sales contact team of sales people, business development, systems engineers and support staff on a global basis. Keep in mind that while some of those Brocadians are network focused, many have connected servers and storage from mainframe to open systems across all vendors for years or in some cases decades. Some of those people who I know personally are even talented enough to sell ice to an Eskimo (that is a sales joke btw).

Sure the Brocadians would have to be leveraged to keep selling what they have done, a task similar to what NetApp is currently facing with their integration of Engenio.

However that DNA could help Dell set up more presences in organizations where they have not been in the past. In other words, Dell could use networking to pull the rest of their product lines into those accounts, vars or resellers.

Hmmm, does that sound like another large California based networking company?

Dell

After all, June is a popular month for weddings, lets see what happens next week down in Orlando during the Dell Storage Forum as some have speculated might be a launching pad for some type of deal.

Here are some related links to more material:

    Using Removable Hard Disk Drives (RHDDs)

    Removable hard disk drives (RHDD) are a form of removable media which includes magnetic tape that address many common use cases. Usage scenarios include enabling bulk data portability for larger environments or for D2D backup where the media needs to be physically moved offsite for small and mid sized environments. RHDDs include among others those from Imation such as the Odyssey (which is what I use) and the Prostor RDX (OEMed by Imation and others). RHDD, tape along with other forms of portable media including those that use flash by being removable and portable presumable should have some extra packaging protection to safeguard against static shock in addition to supporting encryption capabilities.

    Compared to disks including RHDD, tape for most and particularly larger environments should have an overall lower media cost for parking, preserving and when needed serving inactive or archived data (e.g. the changing roll of tape from day to back up to archive). Of course your real costs will vary by use in addition to how combined with data footprint reduction and other technologies.

    A big benefit of RHDDs is that they are random meaning data can be searched and found quickly vs. tape media which has great sequential or streaming capabilities if you have a system that can support that ability. The other benefit of RHDD is that depending on their implementation, they should plug and play with your systems appearing as disk without any extra drivers or configuration or software tools making for ease of use. Being removable they can be used for portability such as sending data to a cloud or MSP as part of an initial bulk copy, or sending data offset or taking home as part of an offsite backup, data protection or BC/DR strategy as well as being used for archiving. The warning with RHDD is their cost per TByte will generally be higher than compared to tape as well as having to have a docking station or specific drive interface depending on specific product and configuration.

    RHDD are a great compliment to traditional fixed or non removable disk, Hybrid Hard Disk Drive (HHDD) and Solid State Device (SSD) based storage as well as coexist with cloud or MSP backup and archive solutions. The smaller the environment the more affordable using RHDD become vs. tape for backup and archive operations or when portability is required. Even if using a cloud or managed service provider (MSP) backup provider, network bandwidth costs, availability or performance may limit the amount of data that can be moved in a cost effective way. For example placing an archive and gold or master copy of your static data on a RHDD that may be kept on site in a safe off-site place and then sending data that is routinely changed to the cloud or MSP provider (think full local and offsite plus partial full and incremental in the cloud).

    By leveraging archiving and data footprint reduction (DFR) techniques including dedupe and compression, you can stretch your budget by sending less data to cloud or MSP services while using removable media for data protection. You would be surprised how many TBytes of data can be kept in a safe deposit box. For my own business, I have used RHDDs for several years to keep gold master copies as well as archives offsite as part of a disk to disk (D2D) or D2D2RHDD strategy. The data protection strategy is also complimented by sending active data to a cloud backup MSP (encrypted of course). It might be belt and suspenders, however it is also eating my own dog food practicing what I talk about and the approach has proven itself a few times.

    Here are some related links to more material:
    Removable disk drives vs. tape storage for small businesses

    The new Green IT: Efficient, Effective, Smart and Productive

    Given the buzz about big data and conversations or confusion around clouds along with virtualizing virtually anything possible, Green IT has fallen off the Buzzword Bingo Bandwagon.

    Green IT like so many other buzzwords and trends typically go through a hype cycle before getting tired, worn out, or disillusioned (see here and here). Often these buzzwords will go to Some Day Isle for some rest and recuperation before reappearing later as part of a second or third buzzword wave either making it to broad adoption which means the plateau of profitability (for vendors or vars) and productivity (for customers) or disappearing.

    Some Day Isle for those not familiar with it is a visional or fictional place that some day you will go to, a wishful happy place so to speak that is perfect for hyperbole R and R. After some R and R, these trends, technologies or techniques often reappear well rested and ready for the next wave of buzz, FUD, hype and activity.

    Keep in mind that industry adoption (e.g. everybody is talking about it) can differ from industry deployment (e.g. some people have actually paid for, deployed and using the technology) to broad customer adoption (e.g. many people are actually paying for, deploying and using the technology on a routine basis).

    Confusion still reigns around Green IT not surprising given the heavy dose of Green Washing that has occurred.

    Consequently Green IT themes or pitches often fall on deaf ears as people have either become numb or ignore the Green washing hype or FUD. For example many people will skip reading this post because the word Green is in the title assuming that it is another CO2 or related themed piece missing out on the other themes or messages here. Unfortunately as I have discussed in the past, there remains a Green Gap that results in missed opportunities for vendors, vars, service providers, IT organizations along with those who would like to see environmental benefits or change.

    Another example of a Green gap is messaging around energy avoidance as being efficient vs. using energy in a more productive or effective manner (doing more work with the same or fewer resources) shown in the figure below.

    Tiered Storage
    Expanding focus from energy avoidance to energy usage effectiveness

    In routine conversations with IT professionals it is clear that the Green Gap and thus missed opportunities will continue for some time until the business and economic values of efficient, effective, smart and productive IT are understood to have environmental benefits as a by product and thus being Green. Watch for more missed messaging around CO2 and related themes popular with so called Greenies (or if you prefer environmentalists) that miss the mark with most business and IT organizations.

    Business and thus IT are driven by economics and as such will invest where they can reduce complexity and costs, become more efficient and effective while increasing productivity and reducing waste by working smarter. In other words, by changing how information services are delivered in a smarter more effective efficient manner maximizes what resources are used enabling more to be done in a denser footprint (budget, people staffing, management, power, cooling, floor space) that have positive environmental benefits. Put another way, a benefit for IT organizations to remove complexity results in lower costs, by becoming more efficient and effective reducing waste results in better productivity and fewer missed opportunities meaning enhanced profits. The net result is that environmental concerns get a free ride or being funded as a result of IT organizations improving their productivity which of course should have a business benefit.

    Efficient and Optimized IT Wheel of Oppourtunity
    Wheel of Opportunity: Various techniques and technologies for infrastructure optimization

    Efficient and effective IT (aka the other Green IT) that links to common technology and business issues with the benefit of helping the environment can be accomplished using a combination approaches. The approaches for enabling an efficient, effective, smarter and productive IT environment includes from a generic perspective various technologies, techniques and best practices shown in the wheel of opportunity figure.

    For example:

    Here are some related links for additional reading:

    The data storage prayer

    On a lighter note.

    For those who follow or are involved with data storage religiously with a passion, then this is for you. As for others who do not get or understand what this is about, just ask those who are devout data storage followers.

    Now I lay my data to sleep
    I pray the lord my backups to keep
    If a disk should die before I wake
    I hope like heck RAID works and my resume is up to date

    Nuff said, now get back to work or what ever it was you were doing before reading this and best wishes!

    Is FCoE Struggling to Gain Traction, or on a normal adoption course?

    Here is an article by Drew Robb over at Enterprise Storage Forum about Fibre Channel over Ethernet (FCoE) and its state of adoption. Drews article includes comments and perspectives from myself around where FCoE is going and why it is on a long road and not a sprint for a short temporal technology play (e.g. not a quick passing fad or bandwagon trend).

    If you measure FCoE adoption in months, sure, its been slow to gain adoption and deployment similar to how Ethernet, Fibre Channel (FC) and even iSCSI took time to evolve. Part of the time involved is for developing the standards, implementing the technology as well as expanding the capabilities of the new tools. Another part of the time required for technologies that are targeted to be around for a decade or more include ecosystem maturity, education not to mention customers being comfortable with along with having budget to buy the new items.

    I have previously said that FCoE was in the trough of disillusionment and depending on your view, that could be either entering, exiting or there to stay. Not surprisingly some cheerleaders thought that saying FCoE was in the trough of disillusionment was being cynical, while some cynics were cheerleading.

    My point around FCoE is that any technology or paradigm that goes through a hype cycle that will actually have long term legs or be around for years if not decades goes through a post initial hype disillusionment phase before reappearing. Technologies or trends that go through the trough of disillusionment that will eventually reappear sometimes go to Some Day Isle for rest and relaxation (R and R). Some Day Isle for those not familiar with it is a visional or fictional place that some day you will go to, a wishful happy place so to speak that is perfect for hyperbole R and R. After some R and R, these trends, technologies or techniques often reappear well rested and ready for the next wave of buzz, fud, hype and activity.

    Certainly there have been and will continue to be more battles or matches tied to early deployments along with plenty of hype or FUD. After all, if FCoE were to simply pack up and go away like some cynics or naysayers suggest, what will they have to talk, blog, write or speak about? Similarly if FCoE magically goes mainstream tomorrow, the cheerleaders will have to find a new bandwagon or Shiny New Toy (SNT) to rally around.

    Also as I have said in the past, its not if, rather when FCoE will be deployed in yours or your customers environment along with how and using what tools or technologies. Another question to pose around FCoE as a converged technology is will you use it in a true converged manner meaning adapting how server, storage and networking resources are managed including best practices? Or, will you use FCoE in a hybrid SAN or LAN mode using traditional SAN and LAN management practice and separate teams perhaps even battling over who owns the tools or technology.

    Fwiw, in case you did not pick up on it from my previous posts, tips, articles and coverage in books, I think that FCoE has a very bright future as does NAS and iSCSI along with shared SAS as complimentary technologies when used for the applicable scenario.

    What is your take, Is FCoE struggling to gain traction?

    Is FCoE on a normal technology evolution path and timeline?

    Is it too early to tell what the future holds for FCoE?

    Is FCoE too little to late and if so why?

    Ok, nuff said for now.

    From bits to bytes: Decoding Encoding

    With networking, care should be taken to understand if a given speed or performance capacity is being specified in bits or bytes as well as in base 2 (binary) or base 10 (decimal).

    Another consideration and potential point of confusion are line rates (GBaud) and link speed which can vary based on encoding and low level frame or packet size. For example 1GbE along with 1, 2, 4 and 8Gb Fibre Channel along with Serial Attached SCSI (SAS) use an 8b/10b encoding scheme. This means that at the lowest physical layer 8bits of data are placed into 10bits for transmission with 2 bits being for data integrity.

    With an 8Gb link using 8b/10b encoding, 2 out of every 10 bits are overhead. To determine the actual data throughput for bandwidth, or, number of IOPS, frames or packets per second is a function of the link speed, encoding and baud rate. For example, 1Gb FC has a 1.0625 Gb per second speed which is multiple by the current generation so 8Gb FC or 8GFC would be 8 x 1.0625 = 8.5Gb per second.

    Remember to factor in that encoding overhead (e.g. 8 of 10 bits are for data with 8b/10b) and usable bandwidth on the 8GFC link is about 6.8Gb per second or about 850Mbytes (6.8Gb / 8 bits) per second. 10GbE uses 64b/66b encoding which means that for every 64 bits of data, only 2 bits are used for data integrity checks thus less overhead.

    What do all of this bits and bytes have to do with clouds and virtual data storage network?

    Quite a bit when you consider what we have talked about the need to support more information processing, moving as well as storing in a denser footprint.

    In order to support higher densities faster servers, storage and networks are not enough and require various approaches to reducing the data footprint impact.

    What this means is for fast networks to be effective they also have to have lower overhead to avoid moving more extra data in the same amount of time instead using that capacity for productive work and data.

    PCIe leverages multiple serial unidirectional point to point links, known as lanes, compared to traditional PCI that used a parallel bus based design. With traditional PCI, the bus width varied from 32 to 64 bits while with PCIe, the number of lanes combined with PCIe version and signaling rate determines performance. PCIe interfaces can have one, two, four, eight, sixteen or thirty two lanes for data movement depending on card or adapter format and form factor.  For example, PCI and PCIx performance can be up to 528 MByte per second with 64 bit 66 MHz signaling rate.

    Table 1: PCIe generation comparisons

    Table 1 shows performance characteristics of PCIe various generations. With PCIe Gen 3, the effective performance essentially doubles however the actual underlying transfer speed does not double as it has in the past. Instead the improved performance is a combination of about 60 percent link speed and 40 percent efficiency improvements by switching from an 8b/10b to 128b/130b encoding scheme among other optimizations.

    Table 2: Common encoding

    Bringing this all together is that in order to support cloud and virtual computing environments, data networks need to become faster as well as more efficient otherwise you will be paying for more overhead per second vs. productive work being done. For example, with 64b/66b encoding on a 10GbE or FCoE link, 96.96% of the overall bandwidth or about 9.7Gb per second are available for useful work.

    By comparison if an 8b/10b encoding were used, the result would be only 80% of available bandwidth for useful data movement. For environments or applications this means better throughput or bandwidth while for applications that require lower response time or latency it means more IOPS, frames or packets per second.

    The above is an example of where a small change such as the encoding scheme can have large benefit when applied to high volume or large environments.

    Tape talk time (tape summit and tape is alive, for some)

    Welcome to the tape summit resources and tape summit resources micro site with links for those who are interested in magnetic tape for backup, archive, BC, DR, big and little data

    For being a declared dead or zombie technology (here, here or here) tape remains very much alive however its role is changing. There is no disputing that hard disk drives (HDDs) are continuing to expand their role for data protection including backup/restore, BC and DR where tape has been used  for decades.

    What is also occurring is that tapes role is changing from day to day backup to that of longer term data preservation including archiving with more data stored on tape today than in past history at a lower cost. In fact the continued reduced cost per tape and improved capacity as well as utilization has worked against tape from a marketing competitive standpoint. For example if you look at a chart showing tape (media and drive) revenues you see a decline, similar to what was seen a couple of years ago for HDDs.

    What is not shown on some charts are how many units (drives or media) shipped with more capacity for a given price (again what was reported for HDDs a few years ago) when net capacity had increased. Vendors of tape technology have also had a rather low profile particular for those with other technologies that have received more marketing resources (people, time, money). After all, if a product is on a plateau of productivity and profitability why spend time or effort on extensive marketing or promotion vs. directing resources to get new items into the market.

    As a result, for those looking to make a case that tape is on the decline based on revenues to convince customers to move away from that technology should have a marketing freebie. Recently Oracle announced a new large capacity tape drive and media following on previous announcements of enhanced LTO roadmap and future 35TByte  tape capabilities announced January 2010 by Fujifilm and IBM.

    For those who are interested following are some links to various topics including how SSD, HDD and tape can coexist complementing each other for different roles or functions. As to those who do not like tape, feel free to read if you like as there is also material on SSD, HDD, dedupe, cloud, data protection and other topics.

    Some previous blog posts:

    Here are some additional articles, commentary and reports pertaining to tape related topics:

    Something tells me we will be hearing, reading or watching more about tape being alive in the months to come.
