A Storage I/O Momentus Moment

I recently asked for and received from Seagate (See recent post about them moving their paper head quarters to Ireland here) a Momentus XT 500GB 7200 RPM 2.5 Hybrid Hard Disk Drive (HHDD) to use in an upcoming project. That project is not to test a bunch of different Hard Disk Drives (HDDs), HHDDs, Removable HDD (RHDDs) or Solid State Devices (read more about SSDs here and here or storage optimization here) in order to produce results for someone for a fee or some other consideration.

Do not worry, I am not jumping on the bandwagon of calling my office collection of computers, storage, networks and software the StorageIO Independent hands on test lab. Instead, my objective is to actually use the Momentus XT in conjunction with other storage I/O devices ranging from notebook or laptop, desktop or server, NAS and cloud based storage in conjunction with regular projects that Im working on both in the office as well as while traveling to various out and about activities.

More often than not these days, common thinking or perception is that if anybody is talking about a product or technology it must be a paid for activity as why would anyone write or talk about something without getting or expecting something in exchange (granted there are some exceptions). Given this era of transparency talk, lets walk the talk and here is my disclosure which for those who have read my content before hopefully you will realize that disclosures should be simple, straight forward, easy, fun and common sense based instead of having to dance around or hide what may be being done.

Disclosure moment:
This is not a paid for or sponsored blog (read my disclosure statement here) and in fact is no way connected to in conjunction with, endorsed, sanctioned or approved by Seagate for that matter nor have they been and currently are not a client. I did however ask them for and they offered to send to me a single 500GB Momentus XT Hybrid Hard Disk Drive (HHDD) with no enclosure, accessories, adapter, cables, software or other packaging to be used for a project I am working on. However I did buy from Amazon.com a Seagate GoFlex USB 3.0 to SATA 3 connection cable kit that I had been eyeing for some other projects. Nuff said about that.

What am I doing with a Seagate Momentus XT
As to the project I am working on, it has nothing to do with Seagate or any other vendors or clients for that matter as it is a new book that I will tell you more about in future posts. What I can share with you for now is that it is a follow on to my most previous books ( The Green and Virtual Data Center (CRC) and Resilient Storage Networks (Elsevier) ). The new book will also be published by CRC Taylor and Francis.

Now for those who are interested in why would I request a Momentus XT Hybrid Hard Disk Drive (HHDD) from Seagate while turning down others offers of free hardware, software, services, trips and the like it is many fold. First I already own some Momentus (as perhaps you do and may not realize it) HDDs thus thought it would be fun and relatively straight forward to make some general comparisons. I needed some additional storage and I/O improvements to compliment and coexist with what I already have.

Does this mean that the book is going to be about flash Solid State Devices (SSD) since I am using a Momentus XT HHDD? The short answer is NO, it will be much more broadly focused however certainly various types of storage I/O control, public and private clouds, management, gaining control, networking, virtualization as well as other hardware, software, services techniques and technologies will be discussed building on my two previous books.

In addition, I want to see how compatible and useful in every day activities the HHDDs are as opposed to running a couple of standard iometer or other so called lab bench tests. After all, when you buy storage or any IT solutions, do you buy them to be used in your lab to run tests, or, do you buy them to do actual day to day tasks?

I also have been a fan of the HHDD as well as flash and DRAM based SSDs for many years (make that decades for SSDs) and see the opportunity to increase how I am actually using HDDs, HHDDs, SSDs as well as Removable Hard Disk Drives (RHDD) in conjunction with NAS, DAS and other storage to support my book writing as well as other projects that I have bought in the past.

What is the Seagate Momentus XT
The Seagate Momentus series of HDDs are positioned as desktop, notebook and laptop devices that vary in rotational speed (RPM), physical form factor, storage capacity as well as price. The XT is a Hybrid Hard Disk Drive (HHDD) that is essentially a best of breed (hence Hybrid) type device incorporating the high capacity and low cost of a traditional 2.5 7200 RPM HDD with performance boost of flash SSD memory. For example some initial testing of working with very large files have found that the XT can in some instances be as fast as a SSD while holding 10x the capacity with a favorable price.

In other words, an effective balance of cost per GByte capacity, cost per IOP and energy efficiency per IOP. This does not mean however that an XT should be used everywhere or for a replacement to DRAM or flash SSD quite to the contrary as those devices are good tools for specific needs or applications. Instead, the XT provides a good balance of performance and capacity to bridge the gap between traditional spinning HDDs price per capacity and performance per cost of SSD. (For those interested, here is a link to what Seagate is doing with SSD e.g. Pulsar in addition to HHDD and HDD).

Value proposition and business (or consumer) benefits moment
What is the benefit, why not just go all flash?

Simple and that is price unless your specific needs fit into the capacity space of an SSD and you need both the higher performance and lower energy draw (with subsequent heat generation). Note that I did not say heat elimination as during a recent quick test of copying 6GB of data to a flash based SSD it was warm just as the XT device was, however also a bit cooler than a comparable 7200 RPM 2.5 drive. If you can afford the full SSD flash or dram based device as well as it fits your needs and compatibility, go for it. However also make sure that you will see the full expected benefit of adding a SSD to your specific solutions as not all implementations are the same (e.g. do your homework).

Why not just go all HDD?

Simple, economics and performance which is why as I said back in 2005 that HHDDs had a very bright future and will IMHO drive a wedge between the traditional HDD and emerging flash based SSD markets at least for non consumer devices on a near term basis given their compatibility capabilities.

In other words, you could think of it as a compromise, or as a best of breed. For example I can see where for compatible not to mention cost and customer comfort ability of a known entity HHDD will gain some popularity in desktops, laptops, notebooks as well as other devices where a performance boost is needed however not at the expense of throwing out capacity or tight economic budgets.

I can also see some interesting scenarios for hosting virtual machines (VMs) to support server Virtualization with VMware, HyperV or Xen based solutions among others. Another scenario is for bulk storage or archive and backup solutions where the HHDD with their extended cache in the form of flash can help to boost performance of read or write operations on VTLs and dedupe devices, archive platforms, backup or other similar functions. Sure the Momentus XT is positioned as a desktop, notebook type device however has that ever stopped vendors or solution providers from using those types of devices in different roles other than what they were designed for? I am just sayin.

Speeds, feeds and buzzword bingo moment
Seagate has many different types of disk drives that can be found here. In general, the Momentus XT is a 2.5 small form factor (SFF) Hybrid Hard Disk Drive (HHDD) available in 500GB, 320GB and 250GB capacity (I have the 500GB model ST95005620AS) with 4GB SLC NAND (flash) SSD memory, 32MB of drive level cache, an underlying 7200RPM disk drive with SATA 3Gb/s interface including as well as Native Command Queuing (NCQ). Now if you want to say that the XT implements tiered storage in a single device (DRAM, flash and HDD) go ahead. Following are a couple of links of where you can learn more.

Seagate FreeAgent Goflex Upgrade Cable (USB 3.0 to SATA 3 STAE104) (Seagate site and Amazon)

Seagate Momentus XT site with general information, product overview and data sheets as well as on Amazon

What does a Momentus XT have to do with writing a book?
If you have ever written a book, or for that matter, done a large development project of any type then things should be a bit familiar. These types of projects include the needs to keep organized as well as protected multiple copies of documents (a dedupers dream) including text, graphics or figures, spreadsheets not to mention project tracking material among others. Likewise as is the case with other authors who work for a living, much of these books are written, edited, proofed or thought about while traveling to different vents, client sites, conferences, meetings or on vacation for that matter. Hence the need to have multiple copies of data on different devices to help guard against when something happens (note that I did not say if).

This is nothing new as each of my last two solo book projects as well as when I was a coauthor contributing content to other books including The Resilient Enterprise (Veritas/Symantec). Much of the content was created while traveling relying on portable storage and backup while on the road. Something someone pointed out to me recently is that this is an example of eating your own dog food or eliminating the shoe makers children syndrome (where the shoe maker creates shoes for others however not for his own children).

Initial moments and general observations
From time to time I will post some notes and observations about how the Momentus XT is performing or behaving which if all goes as planned and so far has, it should be very transparent coexisting with some of my Removable Hard Disk Drives (RHDD) such as the Imation Odyssey which I bought several years ago for offsite bulk removable storage of data that goes to a secure vault somewhere.

Initial deployment other than a stupid mistake on my part has been smooth. What was the stupid mistake you ask? Simple, when I attached the drive via a USB 3.0 cable to SATA 3 connector to one of my XP SP3 systems, Windows saw the device however it did not show up in the list of available devices. Ok, I know I know, it was late in the evening however that is no excuse for realizing that the disk had not yet been initialized let alone formatted. A quick check using Seatools (free here) showed all was well. I then launched Windows Disk Manager, did the initialize, followed by format and all was good from that point on. Wow, wonder how much credibility I will lose over that gaff with the techno elite (that is a joke and a bit of humor btw).

I have already done some initial familiarization and compatibility testing with some of my other drives including a 2.5 64GB SATA flash SSD as well as a 2.5 7200RPM HDD both that I use for bulk data movement activities. At some point I also plan on attaching the XT to my Iomega IX4 NAS to try various things as I have done with other external devices in the past.

Granted these were not ideal conditions as I was in hurry and wanted to get some quick info. Given the probably less than ideal configuration as the format after the HDD was first initialized took about an hour using a FAT32 plug and play configuration. With NTFS and other optimizations I assume it can be better however this was again just to get an initial glimpse of the device in use.

Given that it is a HHDD that uses flash as a big buffer with a 500GB HDD plus 32MB of cache as a backing store, it was interesting attaching it to the computer, then waiting a few minutes, then launching a file copy. Where a normal HDD would start slightly vibrating due to rotation, it was a few moments before any vibration or noise was detected on the Momentus XT which should be of no surprise as the flash was doing its job acting as a buffer until the HDD spun up for work.

I did some initial file copying back and forth between different computers while LAN and NAS were busy doing other things including backups to the Mozy cloud. No discrete time or performance benchmarks to talk about yet, however overall, the XT not surprisingly does seem to be a bit faster than another external 7200 RPM 2.5 drive I use for bulk data moves both on reads and writes. Likewise, given that it is a hybrid HDD leveraging flash as an extended cache with an underlying HDD plus 32MB of cache, it may not always be as fast as my external 2.5 64GB flash SSD, however that is also a common apples to oranges comparison mistake (more on that in a future post).

For example, copying over 6GBytes of data (5 large files of various size) from a 7200 RPM 2.5 160GB Momentus drive in a laptop to the HHDD XT and a flash SSD both took about 8 to 9 minutes where as the normal copy to a 2.5 5400 RPM HDD takes at least 14 to 15 minutes if not longer. Note that these are very rough and far from accurate or reflective comparisons rather a quick gauge of benefits (e.g. getting data moved faster). When I get around to it, will do some more accurate comparisons and put into a follow up post. However I can see already where the XT has the performance similar to the SSD however with almost 10x the capacity which means it could possibly have an interesting role in supporting disk to disk (D2D) backups which I will give a try.

Eventually I will be removing the USB connector kit and actually installing the Momentus into a computer or two (not at the same time) however I am currently walking before running. Im still up in the air as to if I would install the XT into a computer with Windows XP SP3, or simply do a new install of Windows 7 on it to which Im open to thoughts, comments, feedback or applicable suggestions (besides switching to a Macbook or iPad).

Wrap up and fun moment

In the above photo, there is the Seagate Momentus (ST95005620AS), a Goflex USB 3.0 to SATA conversion attachment cable (docking device), a fortune cookie, couple of US quarters and Canadian two dollar coins (See out and about update), paper clips and fishing bobber on a note pad. Why the coins to show relative size and diversity across different geographies as this device will be traveling (it missed out on recent European trip to Holland).

Why the paper clips? Simple, why not, you never know when you will need one for something such as a MacGyver moment, or for pushing the tiny reset button on a device among other activities.

How about the fortune cookie? For good luck and I might need a quick snack while having a cup of coffee not to mention Chinese as well as Asian in general is one of my favorites cuisines to prepare or cook not to mention eat.

Oh, what about the fishing bobber? Why not, it was just laying around and you could also that Im fishing for information to see how the device fits into normal use or that it is there for fun or to add color to the photo.

Oh, and the note pad? Hmm, well, if you cannot figure that one out besides being a back drop, lets just say that the Momentus line in general as well as XT specifically are targeted for notebook, desktop, laptop or other deployment scenarios. If you still dont see the connection, ok fine, feel free to post a comment and I will happily clarify it for you.

That is all for the moment, however I will be following up with more soon.

In the meantime, enjoy your summer if in the northern hemisphere (or winter if in the south).

Take lots of photos, videos and make audio recordings to fill up those USB flash thumb drives (consumer SSD), SD memory cards, computer hard drives, cloud and online web hosting sites so that have you something to remember your special out and about moments by.

Ok, nuff said.

Gregs StorageIO Out and About Update: June 2010

With the 2010 summer solstice having occurred in the northern hemisphere that means it is time for a quick out and about update. It has been a busy winter and spring in the office, on the road as well as at home.

Some results of this recent activity have appeared in blog, on my web site as well as via other sites and venues. For example, activity or content ranges from Industry Trends and Perspectives white papers, reports, blogs, newsletter commentary, interviews, Internet TV, videos, web cast, pod casts (including several appearances on StorageMonkeys Infosmack as well as Rich Brambleys Virtumania), ask the expert (ATE) questions, twitter tweets, tips and columns. Then there were the many in person presentations, key note and seminar events, conferences, briefing sessions along with virtual conferencing and advisory consulting sessions (read and see more here).

Greg Schulz and StorageIO in the news

Regarding having new content appearing in different or new venues, Silicon Angle (including a video), Newstex and Enterprise Efficiencies join the long list of industry and vertical, traditional along with new world venues that my content as well as industry trends and perspective commentary appear in. Read more about events and activities here, content here or commentary here.

Speaking of books, there is also some news in that The Green and Virtual Data Center (CRC) is now available on Amazon Kindle (click on links below) as well as having been translated and published in China not to mention having undergone another round of printing keeping up with demand to make more copies available via global venues.

The Green and Virtual Data Center Chineese Edition: ISBN 978-7-115-21827-8

As for what am I seeing and hearing, check out the new series of Industry Trends and Perspective (ITP) short blog posts that compliment other posts as well as content found on the main web site. These ITP pieces capture what I am hearing and seeing (that is of those what I can talk about that are not under NDA of course) while out and about.

Some of the cities that I have been at while out and about doing keynote speaking and seminar events as well as for other meetings have included Minneapolis, Miami, San Diego, Beverly Hills, San Jose, San Diego (again), Hollywood (again), Austin, Miami (again), New York City, Reston, Minneapolis (again), Irvine, New York City (again), Boston, Toronto, Atlanta, Chicago, Columbus, Philadelphia, Mountain View, Mahtomedia (Minneapolis area), Boston (again) and Indianapolis, Calgary, Jasper (Alberta), Vancouver in Canada as well as Nijkerk (Netherlands) for a one day seminar covering Industry Trends and Perspectives in addition to changing planes in Atlanta, Detroit, Memphis and Las Vegas.

The Planes should be obvious, however what about automobiles you ask? How about the following taken from my rental car while driving north of LAX on the 405 after a January storm during my trip from San Diego after a morning event to Beverly Hills to do an evening keynote.

Another car trip a few weeks later after a different event in San Diego I had a driver from a service behind the wheel so that I could get some work done before an evening meeting. Also on the car front, after flying into Indianapolis there was a car ride to Indianapolis Motor Speedway (IMS) to do a keynote for a CDW sponsored event in gasoline alley a few days before the big race there. While we are on the topic of automobiles and technology, if you have not seen it, check out a post I did about what NAS, NASA and NASCAR have in common.

What about trains you ask?

VIA Rail: The CanadianWaiting for morning Train at Nijkerk Station to take me to Amsterdam Airport

Besides the normal airport trams or trains, there was a fun Amtrak Acela ride from New York City Penn station after a morning event in the city up to Boston so as to be in place for a morning event the next day. Other train activity besides airport, subway or commuter light rail in the US and Europe (Holland), there was also an overnight trip on VIA Rail Canada the Canadian from Jasper Alberta to Vancouver (some business tied into a long weekend). If you have never been to the Canadian Rockies, let alone traveled via train, check this one, it was a blast and I highly recommend it.

It just dawned on me, what about any out and about via boats?

Other than the Boston water taxi to Logan Airport from the convention center where EMCworld was held and that I did an Internet TV interview along with @Stu and @Scott_Lowe, boat activity has been so far relegated to relaxation.

However, as all work and no play could make for a dull boy (or girl), I can update you that the out and about via boat fishing and sightseeing activity has been very good so far this fall even with high (then low, then high) water on the scenic St. Croix river way.

Here are some scenes from out and about on the St. Croix river including an eagle in its nest tending to its young who can not be seen in this photo as well as fishing (and catching and releasing).

In between travels (as well as during on planes, trains and in hotel rooms) as well as relaxation breaks, I have been also working on several other projects. Some of these can be seen on the news or tips and articles as well as video and pod cast pages in addition to custom research as well as advisory consulting services. I have also been working on some other projects some of which will become visible over the next weeks and months, others not for a longer period of time yet and yet others that fall under the NDA category so that is all I have to say about that.

If you are not receiving or have seen them, the inaugural issue of the Server and StorageIO newsletter appeared in late February followed by the second edition (Spring 2010) this past week. Both can be found here and here as well as at www.storageio.com/newsletter or subscribing via newsletter@storageio.com.

StorageIO Newsletter

A question I often get asked is what am I hearing or seeing particularly with regards to IT customers as well as with vars during my travels. Here are some photos covering some of the things that I have seen so far this year while out and about.

As to what am I seeing and hearing pertaining to IT, storage, networking and server trends or issues they include among others (see the newsletter):

Whats on deck and and that I am working on?

Having had a busy fun winter and spring Im going to get some relaxation time in during a couple of week period of no travel, however there is plenty to do and get ready for. The summer months will slow down a bit on the out and about travel events scene, however not to a complete stop. In between preparing for upcoming events, advisory and consulting activities as well as researching new material and topics not to mention working on some projects that you will see or hear more about in the weeks and months to come.

For example I will be a guest on a webcast sponsored by Viridity discussing the importance of data center metrics, measurement and insight for effective management to enable energy efficient and effective data centers on July 8th. In addition, I will also be doing another five city storage virtualization series in Stamford, Cleveland, Miami, Tampa and Louisville during mid to late July among other upcoming activities including VMworld in San Francisco.


Check out the events page for more details, specific dates and venues.

What about you?

What have you been doing or have planned for your summer?

Let me know what you are seeing or hearing as well as have been doing.

In the meantime however keep these hints and tips in mind:

  • Have plenty of reading material (real physical books or magazines) or virtual (Kindle or other) as well as via Internet or online to read while at the beach (make sure your computer or PDA is backed up), pool side, in the backyard or elsewhere
  • Remember your eye shades (sun glasses or eye wear), hat and sun screen and if applicable, inspect or bug repellant (e.g. RAID is still useful)
  • Drink plenty of liquid fluids while outside in the summer heat including non alcoholic ones that do not have umbrellas or other interesting garnish
  • Have a place to backup and protect all those summer photos, videos and audio clips that you record while on your out and about adventure. However, keep in mind privacy concerns when uploading them to various social mediums. After all, what happens in Vegas stays in Vegas and what happens on the web stays on the web!

Thanks to everyone involved in the recent events which can be seen here, as well for those who will be participating in upcoming ones I look forward to meeting and talking with you.

Until next time have a fun, safe and relaxing summer if you are in the northern hemisphere and for those down under, not to worry, spring is on the way soon for you as well.

Initial Virtumania Appearance (Episode 14) with fellow vExperts

This past week I was invited to join some fellow vExperts as a first time guest on Rich Brambleys (@rbrambley and VMETC) podcast show called Virtumania.

Episode 14 (Virtualization and Networking Turf Wars) had as a theme as you can guest themes around physical, logical and virtual networking for virtual servers along with some of the politics and turf battles associated with managing those entities.

Also on the show were cohost Marc Farley (@3parfarley) of 3Par and StorageRap.com as well as regular guest Rick Vanover (@rickvanover) of RickVanover.com and other special guest David Davis (@davidmdavis) vmwarevideos.com in addition to myself.

For some fun, there is even some reference to rival gangs dancing for superiority in the Michael Jackson music video "Bad" which was produced by Greg Knieriemen (@knieriemen) of Chi Corporation for this Infosmack Production.

Check out the show here or here.

BTW: Is it just me or does Rich Brambley sound a little bit like Tom Petty without the accent?

Thanks guys, enjoyed being a guest on the show as well as talking with you all, hope to be able to do it again sometime soon.

Industry Trends and Perspectives: Converged Networking and IO Virtualization (IOV)

This is part of an ongoing series of short industry trends and perspectives blog posts briefs.

These short posts compliment other longer posts along with traditional industry trends and perspective white papers, research reports, solution brief content found at www.storageio.com/reports.

The trends that I am seeing with converged networking and I/O fall into a couple of categories. One being converged networking including unified communications, FCoE/DCB along with InfiniBand based discussions while the other being around I/O virtualization (IOV) including PCIe server based multi root IO virtualization (MRIOV).

As is often the case with new technologies the trend of some saying these are the next great things thus drop everything and adopt them now as they are working and ready for prime time mission critical deployment. Then there are those who say no, stop, do not waste your time on these as they are temporary, they will die and go away anyway. In between, there is reality which takes a bit of balancing the old with the new, look before you leap, do your homework, and do not be scared however have a strategy and a plan on how to achieve it.

Thus is FCoE a temporal or temporary technology? Well, in the scope that all technologies are temporary however it is their temporal timeframe that should be of interest. Thus given that FCoE will probably have at least a ten to fifteen year temporal timeline, I would say in technology terms it has a relative long life for supporting coexistence on the continued road to convergence which appears to be Ethernet.

Industry Trends and Perspectives: Storage Virtualization and Virtual Storage

This is part of an ongoing series of short industry trends and perspectives blog posts briefs.

These short posts compliment other longer posts along with traditional industry trends and perspective white papers, research reports, solution brief content found at www.storageio.com/reports.

The topic of this post is a trend server virtualization and recent EMC virtual storage announcements.

Virtual storage or storage virtualization has been as a technology and topic around for some time now. Some would argue that storage virtualization is several years old while others would say many decades depending on your view or definition which will vary by preferences, product, vendor, open or closed, hardware, network, software not to mention feature and functionality.

Consequently there are many different views and definitions of storage virtualization some tied to that of product specifications often leading to apples and oranges comparison.

Back in the early to mid 2000s, there was plenty of talk around storage virtualization which then gave way to a relative quiet period before seeing adoption pickup in terms of deployment later in the decade (at least for block based).

More recently there has a been a renewed flurry of storage virtualization activity with many vendors now shipping their latest versions of tools and functionality, EMC announcing VPLEX as well as the file virtualization vendors continuing to try and create a market for their wares (give it time, like block based, it will evolve).

One of the trends around storage virtualization and part of the play on words EMC is using is to change the order of the words. That is where storage virtualization is often aligned with product implementation (e.g. software on an appliance or switch or in a storage system) used primarily for aggregation of heterogeneous storage, with VPLEX EMC is referring to it as virtual storage.

What is interesting here is the play on life beyond consolidation a trend that is also occurring with servers or using virtualization for agility, flexibility and ease of management for upgrades, add, move and changes as opposed to simply pooling of LUNs and underlying storage devices. Stay tuned and watch for more in this space as well as read the blog post below about VPLEX for more on this topic.

Industry Trends and Perspectives: Tape, Disk and Dedupe Coexistence

This is part of an ongoing series of short industry trends and perspectives blog posts briefs.

These short posts compliment other longer posts along with traditional industry trends and perspective white papers, research reports, solution brief content found at www.storageio.com/reports.

The topic of this post is a trend that I am seeing and hearing about during discussions with IT professionals pertaining to how tape is still alive despite common industry FUD.

Not only is tape still very much alive with recent enhancements including LTO5 with an extended range roadmap, it is also finding new roles. In addition to being deployed in new roles, tape is coexisting and complimenting dedupe or other disk based backup and data protection approaches and vice versa.

Hearing tape is alive in the same sentence as dedupe deployments continuing may sound counter intuitive if you only listen to some vendor pitches.

However if you talk with IT customers particularly those in larger environments or with VARs that provide complete solution offering focus you will hear a different tune than tape is dead and dedupe rules. Tape is still alive however its roll is changing. Watch for more on this and related topics.

That is all for now, hope you find this ongoing series of current and emerging Industry Trends and Perspectives interesting.

Industry Trends and Perspectives: Tiered Hypervisors and Microsoft Hyper-V

Storage I/O trends
This is part of an ongoing series of short industry trends and perspectives blog posts briefs.

These short posts complement other longer posts along with traditional industry trends and perspective white papers, research reports, solution brief content found at www.storageio.com/reports.

Multiple – Tiered Hypervisors for Server Virtualization

The topic of this post is a trend that I am seeing and hearing about during discussions with IT professionals of the use of two or more server virtualization hypervisors or what is known as tiered Hypervisors.

Server Virtualization Hypervisor Trends

A trends tied to server virtualization that I am seeing more of are that IT organizations are increasingly deploying or using two or more different hypervisors (e.g. Citrix/Xen, Microsoft/Hyper-V, VMware vSphere) in their environment (on separate physical server or blades).

Tiered hypervisors is a concept similar to what many IT organizations already have in terms of different types of servers for various use cases, multiple operating systems as well as several kinds of storage mediums or devices.

What Im seeing is that IT pros are using different hypervisors to meet various cost, management and vendor control goals aligning the applicable technology to the business or application service category.

Tiered Virtualization Hypervisor Management

Of course this brings up the discussion of how to manage multiple hypervisors and thus the real battle is or will be not about hypervisors, rather that of End to End (E2E) management.

A question that I often ask VARs and IT customers if they see Microsoft on the offensive or defensive with Hyper-V vs. VMware and vice versa, that is if VMware is on the defense or offense against Microsoft.

Not surprisingly the VMware and Microsoft faithful will say that the other is clearly on the defensive.

Meanwhile from other people, the feelings are rather mixed with many feeling that Microsoft is increasingly on the offensive with VMware being seen by some as playing a strong defense with a ferocious offense.

Industry Trends and Perspectives: 6GB SAS and DAS are not Dumb A$$ Storage

Blog: Industry Trends and Perspectives: 6GB SAS and DAS are not Dumb A$$ Storage

This is part of an ongoing series of short industry trends and perspectives blog posts briefs.

These short posts compliment other longer posts along with traditional industry trends and perspective white papers, research reports, solution brief content found at www.storageio.com/reports.

With 6G that increases performance as well as connectivity flexibility, more servers are supporting SAS natively while storage system continue to add support for 3.5" and 2.5" small form factor high performance and large capacity SAS drives. Shared SAS DAS storage systems are being deployed for consolidation attached to two or more servers as well as for clustered solutions.

Another area where shared SAS DAS storage is being deployed is in cloud, scale out NAS and bulk storage environments as a price performance alternative to iSCSI or Fibre Channel solutions.

Keep an eye on these and other trends including converged systems, server, storage and networking management along with associated tools.

Industry Trends and Perspectives Blog Series

This is the first in a series of ongoing short industry trends and perspectives blog post briefs. These short posts compliment other longer posts along with traditional industry trends and perspective white papers, research reports, solution brief content found at www.storageio.com/reports.

I often get asked by people what Im seeing or hearing new (aka what is the Buzz).

Sometimes when I tell those who ask about new things or what they have not read or heard about yet, I get interesting as well as varied sometimes even funny reactions. In most cases unless the person does not agree or like the trend, the reaction shifts to one of wanting to know more including what is driving or causing the activity, its impact along with what can be done.

As some are new or emerging they may not yet be being covered in other venues, research, surveys, studies or reports. Thus do not be surprised or alarmed if there is something listed here or in one of the subsequent series post that you have not seen or read elsewhere yet while others may already be familiar. Some are emerging trends perhaps even being short lived while others will have longer legs to evolve.

Some general trends that I am seeing and hearing from IT professionals include:

Happy Earth Day 2010!

Here in the northern hemisphere it is late April and thus mid spring time.

That means the trees sprouting their buds, leaves and flowering while other plants and things come to life.

In Minnesota where I live, there is not a cloud in the sky today, the sun is out and its going to be another warm day in the 60s, a nice day to not be flying or traveling and thus enjoy the fine weather.

Among other things of note on this earth day 2010 include:

  • Minnesota Twins new home Target Field was just named the most Green Major League Baseball (MLB) stadium as well as greenest in the US with its LEED (or see here) certification.
  • Icelands Eyjafjallajokull volcano continues to spew water vapor steam, CO2 and ash at a slower rate than last week when it first erupted with some speculating that there could be impending activity from other Icelandic volcanos. Some estimates placed the initial eruption CO2 impact and subsequent flight cancellations to be neutral, essentially canceling each other out, however Im sure we will be hearing many different stories in the weeks to come.

  • Image of Iceland Eyjafjallajokull Volcano Eruption via Boston.com

  • Flights to/from and within Europe and the UK are returning to normal
  • Toyota continues to deal with recalls on some of their US built automobiles including the energy efficient Prius, some of which may have been purchased during the recent US cash for clunkers (CFC) program (hmm, is that ironic or what?)
  • Greenpeace in addition to using a Facebook page to protest Facebook data center practices is now targeting cloud IT in general including just before the Apple iPad launch (Heres some comments from Microsoft).
  • Vendors in all industries are lining up for the second coming of Green marketing or perhaps Green Washing 2.0

The new Green IT, moving beyond Green wash and hype

Speaking of Green IT including Green Computing, Green Storage, Virtualization, Cloud, Federation and more, here is a link to a post that I did back in February discussing how the Green Gap continues to exist.

The green gap exists and centers around the confusion of what Green means along with the common disconnects between core IT issues or barriers to becoming more efficient, effective, flexible and optimized from both an economic as well as environmental basis to those commonly messaged to under the green umbrella (read more here).

Regardless of where you stand on Green, Green washing, Green hype, environmentalism, eco-tech and other related themes, for at least a moment, set aside the politics and science debates and think in terms of practicality and economics.

That is, look for simple, recurring things that can be done to stretch your dollar or spending ability in order to support demand (See figure below) in a more effective manner along with reducing waste. For example to meet growing demand requirements in the face of shrinking or stagnate budgets, the action is to stretch available resources to do more work when needed, or retain more where applicable with the same or less footprint. What this means is that while common messaging is around reducing costs, look at the inverse which is to do more with available budgets or resources. The result is green in terms of economic and environmental benefits.

IT Resource demand
Increasing IT Resource Demand

Green IT wheel of oppourtunity
Green IT enablement techniques and technologies

Look at and understand the broader aspects of being green which has both economical and environmental benefits without compromising on productivity or functionality. There are many aspects or facets of being green beyond those commonly discussed or perceived to be so (See Green IT enablement techniques and technologies figure above).

Certainly recycling of paper, water, aluminum, plastics and other items including technology equipment are important to reduce waste and are things to consider. Another aspect of reducing waste particularly in IT is to avoid rework that can range from finding network bottlenecks or problems that result in continuous retransmission of data for failed backup, replication or data transfers that cause lost opportunity or resource consumption. Likewise programming errors (bugs) or miss configuration that results in rework or lost productivity also are forms of waste among others.

Another theme is that of shifting from energy avoidance to energy efficiency and effectiveness which are often thought to the same. However the expanded focus is also about getting more work done when needed with the same or less resources (See figure below) for example increasing activity (IOPS, transactions, emails or video served, bandwidth or messages) per watt of energy consumed.

From energy avoidence to effectiveness
Shifting from energy avoidance to effectiveness

One of the many techniques and approaches for addressing energy including stretching resources and being green include intelligent power management (IPM). With IPM, the focus is not strictly centered around energy avoidance, instead about inteligently adapting to different workloads or activity balancing performance and energy. Thus when there is work to be done, get the work done quickly with as little energy as possible (IOP or activity per watt), when there is less work, provide lower performance and thus smaller energy requirements, or when no work to be done, going into additional energy saving modes. Thus power management does not have to be exclusively about turrning off the lights or IT equipment in order to be green.

The following two figures look at Green IT past, present and future with an expanding focus around optimization and effectiveness meaning getting more work done, storing more data for longer periods of time, meeting growth demands with what appears to be additional resources however at a lower per unit cost without compromising on performance, availability or economics.

Green IT wheel of oppourtunity
Green IT: Past, present and future shift from avoidance to efficiency and effectiveness

Green IT wheel of oppourtunity
The new Green IT: Boosting business effectiveness, maximize ROI while helping the environment

If you think about going green as simply doing or using things more effectively, reducing waste, working more intelligently or effectively the benefits are both economical and environmentally positive (See the two figures above).

Instead of finding ways to fund green initiatives, shift the focus to how you can enable enhanced productivity, stretching resources further, doing more in the same or smaller footprint (floor space, power, cooling, energy, personal, licensing, budgets) for business economic and environmental sustainability with the result being environmental encampments.

Also keep in mind that small percentage changes on a large or recurring basis have significant benefits. For example a small change in cooling temperatures while staying within vendor guideline recommendations can result in big savings for large environments.

 

Bottom line

If you are a business and discounting green as simply a fad, or perhaps as a public relations (PR) initiative or activity tied to reducing carbon footprints and recycling then you are missing out on economic (top and bottom line) enhancement opportunities.

Likewise if you think that going green is only about the environment, then there is a missed opportunity to boost economic opportunities to help fund those inititiaves.

Going green means many different things to various people and is often more broad and common sense based than most realize.

That is all for now, happy earth day 2010

Hard product vs. soft product

In the IT industry space and data storage or computers and servers particularly so, mention hard product or software product and what comes to mind?

How about physical vs. virtual servers or storage, hardware vs. software solutions, products vs. services?

By contrast, in the aviation and airline industry among others, mention hard vs. soft product and there is a slight variation, which is the difference between one providers service delivery experience.

For example, two or more different airlines or carriers may fly the same aircraft perhaps even with the same engines, instrumentation, navigation electronics and base features, all part of the hard product.

However, their hard product could vary by type of seats, spacing or pitch along with width, overhead luggage room, Video on Demand (VoD) or In Flight Entertainment (IFE) as well as different cabin treatments (carpeting, wall coverings) and galley configurations. Even in scenarios where carriers have the same equipment and hard product, their soft product can differ.

Example of a Soft Product, that is service (or lack there of) being delivered

Example of a Soft Product (Service or lack there of being delivered)

The soft product is the service delivery experience including by the cabin crew (flight attendants and pursers), food (or lack of), beverage, presentation and so forth. Also part of the soft product can be how seats are allocated or available for selection, boarding process and other items that contribute to the overall customer experience.

This all got me thinking on a recent flight where the hard product (e.g. aircraft) of a particular carrier was identical; however given transitions taking place, the soft product still differed as was not fully integrated or merged yet. What the experience got me thinking about is that in IT, customers or solution providers can buy the same technology or hard product (hardware, software, services) from the same suppliers yet present different soft products or service experience to their customers.

Example IT hard product (hardware and software) delivering soft product services

IT equipment being used for delivery of different soft products

Im sure that some of the cloud crowd cheerleaders might even jump up and down and claim that is the benefit of using managed service producers or similar services to obtain a different soft product. And while that may be true in some instances, it is also true that different traditional IT organizations are able to craft and deploy various types of soft products to their customers to meet different service requirements, cost or economic objectives using the same technology used by others.

A different example of hard vs soft product is a site I have visited that has mainframes, windows and open systems servers whose business requires a soft product that is highly available, reliable, flexible, fast and affordable. Needless to say, in that environment, some of the open systems including windows platforms can have reliability close to if not equal to the mainframes.

Example IT hard product (hardware and software) delivering soft product services
IT equipment being used for delivery of different soft products

What is even more amazing is that no special or different hard products (e.g. servers, storage, networks or software) are being used to achieve those services objectives. Rather it is the soft product that achieves the results in terms of how the techniques are used and managed. Likewise I have heard of other environments that have mixed mainframe and open systems, using common hard products as other organizations yet whose soft product is not as robust or reliable as others. If using the same hard product that is same software, hardware, networks and services, how could the soft product be any less robust?

The answer is that good and reliable technology is important, however the technology is only as good as how it is managed, configured, monitored and deployed centering on processes, procedures and best practices.

Next time you are on an airplane, or, using some other service that leverages common technologies (hardware or software or networks) take a moment to look around at the soft product and how the service experience of a common hard product can vary. That is, using common technology, how can various best practices, policies and operating principals to meet diverse service requirements differ to meet demand as well as economic requirements.

What is your take and experience on different hard vs soft products in or around IT?

Ok, nuff said.
