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.

StorageIO Momentus Hybrid Hard Disk Drive (HHDD) Moments

This is the third in a series of posts that I have done about Hybrid Hard Disk Drives (HHDDs) along with pieces about Hard Disk Drives (HDD) and Solid State Devices (SSDs). Granted the HDD received its AARP card several years ago when it turned 50 and is routinely declared dead (or read here) even though it continues to evolve along SSD maturing and both expanding into different markets as well as usage roles.

For those who have not read previous posts about Hybrid Hard Disk Drives (HHDDs) and the Seagate Momentus XT you can find them here and here.

Since my last post, I have been using the HHDDs extensively and recently installed the latest firmware. The release of new HHDD firmware by Seagate for the Momentus XT (SD 25) like its predecessor SD24 cleaned up some annoyances and improved on overall stability. Here is a Seagate post by Mark Wojtasiak discussing SD25 and feedback obtained via the Momentus XT forum from customers.

If you have never done a HDD firmware update, its not as bad or intimidating as might be expected. The Seagate firmware update tools make it very easy, that is assuming you have a recent good backup of your data (one that can be restored) and about 10 to 15 minutes of time for a couple of reboots.

Speaking of stability, the Momentus XT HHDDs have been performing well helping to speed up accessing large documents on various projects including those for my new book. Granted an SSD would be faster across the board, however the large capacity at the price point of the HHDD is what makes it a hybrid value proposition. As I have said in previous posts, if you have the need for speed all of the time and time is money, get an SSD. Likewise if you need as much capacity as you can get and performance is not your primary objective, then leverage the high capacity HDDs. On the other hand, if you need a balance of some performance boost with capacity boost and a good value, then check out the HHDDs.

Lets shift gears from that of the product or technology to that of common questions that I get asked about HHDDs.

Common questions I get asked about HHDDs include:

What is a Hybrid Hard Disk Drive?

A Hybrid Hard Disk Drive includes a combination of rotating HDD, solid state flash persistent memory along with volatile dynamic random access memory (DRAM) in an integrated package or product. The value proposition and benefit is a balance of performance and capacity at a good price for those environments, systems or applications that do not need all SSD performance (and cost) vs. those that need some performance in addition to large capacity.

How the Seagate Momentus XT differs from other Hybrid Disks?
One approach is to take a traditional HDD and pair it with a SSD using a controller packaged in various ways. For example on a large scale, HDDs and SSDs coexist in the same tiered storage system being managed by the controllers, storage processors or nodes in the solution including automated tiering and cache promotion or demotion. The main difference however between other storage systems, tiering and pairing and HHDDs is that in the case of the Momentus XT the HDD, SLC flash (SSD functionality) and RAM cache and their management are all integrated within the disk drive enclosure.

Do I use SSDs and HDDs or just HHDDs?
I have HHDDs installed internally in my laptops. I also have HDDs which are installed in servers, NAS and disk to disk (D2D) backup devices and Digital Video Recorders (DVRs) along with external SSD and Removable Hard Disk Drives (RHDDs). The RHDDs are used for archive and master or gold copy data protection that go offsite complimenting how I also use cloud backup services as part of my data protection strategy.

What are the technical specifications of a HHDD such as the Seagate Momentus XT?
3Gbs SATA interface, 2.5 inch 500GB 7,200 RPM HDD with 32MB RAM cache and integrated 4GByte SLC flash all managed via internal drive processor. Power consumption varies depending what the device is doing such as initial power up, idle, normal or other operating modes. You can view the Seagate Momentus XT 500GB (ST95005620AS which is what I have) specifications here as well as the product manual here.

Do you need a special controller or management software?
Generally speaking no, the HHDD that I have been using plugged and played into my existing laptops internal bay replacing the HDD that came with those systems. No extra software was needed for Windows, no data movement or migration tools needed other than when initially copying from the source HDD to the new HHDD. The HHDD do their own caching, read ahead and write behind independent of the operating system or controller. Now the reason I say generally speaking is that like many devices, some operating systems or controllers may be able to leverage advanced features so check your particular system capabilities.

How come the storage system vendors are not talking about these HHDDs?
Good question which I assume it has a lot to do with the investment (people, time, engineering, money and marketing) that they have or are making in controller and storage system software functionality to effectively create hybrid tiered storage systems using SSD and HDDs on different scales. There have been some packaged HHDD systems or solutions brought to market by different vendors that combine HDD and SSD into a single physical package glued together with some software and controllers or processors to appear as a single system. I would not be surprised to see discrete HHDDs (where the HDD and flash SSD and RAM are all one integrated product) appear in lower end NAS or multifunction storage systems as well as for backup, dedupe or other system that requires large amounts of capacity space and performance boost now and then.

Why do I think this? Simple, say you have five HHDDs each with 500GB of capacity configured as a RAID5 set resulting in 2TByte of capacity. Using as a hypothetical example the Momentus XT yields 5 x 4GByte or 20GByte of flash cache helps accelerate write operations during data dumps, backup or other updates. Granted that is an overly simplified example and storage systems can be found with hundreds of GByte of cache, however think in terms of value or low cost balancing performance and capacity to cost for different usage scenarios. For example, applications such as bulk or scale out file and object storage including cloud or big data, entertainment, Server (Citrix/Xen, Microsoft/HyperV, VMware/vSphere) and Desktop virtualization or VDI, Disk to Disk (D2D) backup, business analytics among others. The common tenets of those applications and usage scenario is a combination of I/O and storage consolidation in a cost effective manner addressing the continuing storage capacity to I/O performance gap.

Data Center and I/O Bottlenecks

Storage and I/O performance gap

Do you have to backup HHDDs?
Yes, just as you would want to backup or protect any SSD or HHD device or system.

How does data get moved between the SSD and the HDD?
Other than the initial data migration from the old HDD (or SSD) to the HHDD, unless you are starting with a new system, once your data and applications exist on the HHDD, it automatically via the internal process of the device manages the RAM, flash and HDD activity. Unlike in a tiered storage system where data blocks or files may be moved between different types of storage devices, inside the HHDD, all data gets written to the HDD, however the flash and RAM are used as buffers for caching depending on activity needs. If you have sat through or listened to a NetApp or HDS use of cache for tiering discussion what the HHDDs do is similar in concept however on a smaller scale at the device level, potentially even in a complimentary mode in the future? Other functions performed inside the HHDD by its processor includes reading and writing, managing the caches, bad block replacement or re vectoring on the HDD, wear leveling of the SLC flash and other routine tasks such as integrity checks and diagnostics. Unlike paired storage solutions where data gets moved between tiers or types of devices, once data is stored in the HHDD, it is managed by the device similar to how a SSD or HDD would move blocks of data to and from the specific media along with leveraging RAM cache as a buffer.

Where is the controller that manages the SSD and HDD?
The HHDD itself is the controller per say in that the internal processor that manages the HDD also directly access the RAM and flash.

What type of flash is used and will it wear out?
The XT uses SLC (single level cell) flash which with wear leveling has a good duty cycle (life span) and is what is typically found in higher end flash SSD solutions vs. lower cost MLC (multi level cell)

Have I lost any data from it yet?
No, at least nothing that was not my own fault from saving the wrong file in the wrong place and having to recover from one of my recent D2D copies or the cloud. Oh, regarding what have I done with the HDDs that were replaced by the HHDDs? They are now an extra gold master backup copy as of a particular point in time and are being kept in a safe secure facility, encrypted of course.

Have you noticed a performance improvement?
Yes, performance will vary however in many cases I have seen performance comparable to SSD on both reads and writes as long as the HDDs keep up with the flash and RAM cache. Even as larger amounts of data are written, I have seen better performance than compared to HDDs. The caveat however is that initially you may see little to marginal performance improvement however over time, particularly on the same files, performance tends to improve. Working on large tens to hundreds of MByte size documents I noticed good performance when doing saves compared to working with them on a HDD.

What do the HHDDs cost?
Amazon.com has the 500GB model for about $100 which is about $40 to $50 less than when I bought my most recent one last fall. I have heard from other people that you can find them at even lower prices at other venues. In the theme of disclosures, I bought one of my HHDDs from Amazon and Seagate gave me one to test.

Will I buy more HHDDs or switch to SSDs?
Where applicable I will add SSDs as well as HDDs, however where possible and practical, I will also add HHDDs perhaps even replacing the HDDs in my NAS system with HHDDs at some time or maybe trying them in a DVR.

What is the down side to the HHDDs?
Im generating and saving more data on the devices at a faster rate which means that when I installed them I was wondering if I would ever fill up a 500GB drive. I still have hundreds of GBytes free or available for use, however I also am able to cary more reference data or information than in the past. In addition to more reference data including videos, audio, images, slide decks and other content, I have also been able to keep more versions or copies of documents which has been handy on the book project. Data that changes gets backed up D2D as well as to my cloud provider including while traveling. Leveraging compression and dedupe, given that many chapters or other content are similar, not as much data actually gets transmitted when doing cloud backups which has been handy when doing a backup from a airplane flying over the clouds. A wish for the XT type of HHDD that I have is for vendors such as Seagate to add Self Encrypting Disk (SED) capabilities to them along with applying continued intelligent power management (IPM) enhancements.

Why do I like the HHDD?
Simple, it solves both business and technology challenges while being an enabler, it gives me a balance of performance for productivity and capacity in a cost effective manner while being transparent to the systems it works with.

Another StorageIO Hybrid Momentus Moment

Its been a few months since my last post (read it here) about Hybrid Hard Disk Drive (HHDD) such as the Seagate Momentus XT that I have been using.

The Momentus XT HHDD I have been using is a 500GB 7,200RPM 2.5 inch SATA Hard Disk Drive (HDD) with 4GB of embedded FLASH (aka SSD) and 32MB of DRAM memory for buffering hence the hybrid name.

I have been using the XT HHDD mainly for transferring large multi GByte size files between computers and for doing some disk to disk (D2D) backups while becoming more comfortable with it. While not as fast as my 64GB all flash SSD, the XT HHDD is as fast as my 7,200RPM 160GB Momentus HDD and in some cases faster on burst reads or writes. The notion of having a 500GB HDD that was affordable to support D2D was attractive however the ability to get some performance boost now and then via the embedded 4GB FLASH opens many different possibilities particularly when combined with compression.

Recently I switched the role of the Momentus XT HHDD from that of being a utility drive to becoming the main disk in one of my laptops. Despite many forums or bulletin boards touting issues or problems with the Seagate Momentus XT causing system hangs or Windows Blue Screen of Death (BSoD), I continued on with the next phase of testing.

Making the switch to XT HHDD as a primary disk

I took a few precaution including eating some of my own dog food that I routinely talk about. For example, I made sure that the Lenovo T61 where the Momentus XT was going to be installed was backed up. In addition, I synced my traveling laptop so that it was the primary so that I could continue working during the conversion not to mention having an extra copy in addition to normal on and offsite backups.

Ok, lets get back to the conversion or migration from a regular HDD to the HHDD.

Once I knew I had a good backup, I used the Seagate Discwizard (e.g. Acronis based) tool for imaging the existing T61 HDD to the Momentus XT HHDD. Using Discwizard (you could use other tools as well) I configured it to initialize the HHDD which was attached via a Seagate Goflex USB to SATA cable kit as well as image or copy the contents of the T61 HDD partitions to the Momentus XT. During the several hours it took to copy and create a new bootable disk image on the HHDD I continued working on my travel or standby laptop.

After the image copy was completed and verified, it was time to reboot and see how Windows (XP SP3) liked the HHDD which all seemed to be normal. There were some parts of the boot that seemed a bit faster, however not 100 percent conclusive. The next step was to shutdown the laptop and physically swap the old internal HDD with the HHDD and reboot. The subsequent boot did seem faster and programs accessing large files also seemed to run a bit faster.

Keep in mind that the HHDD is still a spinning 7,200RPM disk drive so comparisons to a full time SSD would be apples to oranges as would the cost capacity difference between those devices. However, for what I wanted to see and use, the limited 4GB of flash does seem to provide a performance boost and if I needed full time super fast performance, I could buy a larger capacity SSD and install it. Im going to hold off on buying any more larger capacity flash SSD for the time being however.

Do I see HHDD appearing in SMB, SME or enterprise storage systems anytime soon? Probably not, at least not in primary storage systems. However perhaps in some D2D backup, archive or dedupe and VTL devices or other appliances.

Momentus XT Speed Bumps

Now, to be fair, there have been some bumps in the road!

The first couple of days were smooth sailing other than hearing the mystery chirp the HHDD makes a couple of times a day. Low and behold after a couple of days, just as many forums had indicated, a mystery system hang occurred (and no, not like Windows might normally do so for those Microsoft cynics). Other than the inconvenience of a reboot, no data was lost as files being updated were saved or had been backed up not to mention after the reboot, everything was intact anyway. So far just an inconvenience or so I thought.

Almost 24 hours later, same thing except this time I got to see the BSoD which candidly, I very rarely see despite hearing stories from others. Ok, this was annoying, however as long as I did not lose any data, other than lost time from a reboot, lets chalk this up to a learning experience and see where it goes. Now guess what, about 12 hours later, once again, the system froze up and this time I was in the middle of a document edit. This time I did lose about 8 minutes of typing data that had not been auto saved (I have since changed my auto save from 10 minutes to 5 minutes).

With this BSoD incident, I took some notes and using the X61s, started checking some web sites and verified the BIOS firmware on the T61 which was up to date. However I noticed that the Seagate Momentus XT HHDD was at firmware 22 while there was a 23 version available. Reading through some web sites and forums, I was on the fence on trying firmware 23 given that it appears a newer firmware version for the HHDD is in the works. Deciding to forge forward with the experiment, after all, no real data loss had occurred, and I still had the X61s not to mention the original T61 HDD to fall back to worse case.

Going to the Seagate web site, I downloaded the firmware 23 install kit and ran it to their instructions which was a breeze and then did the reboot.

It has not been quite a week yet, however knocking on wood, while I keep expecting to see one, no BSoD or system freezes have occurred. However having said that and knocking on wood, Im also making sure things are backed up protected and ready if needed. Likewise, if I start to see a rash of BSoD, my plan is to fall back to the original T61 HDD, bring it up to date and use it until a newer HHDD firmware version is available to resume testing.

What is next for my Seagate Momentus XT HHDD?

Im going to wait to see if the BSoD and mystery system hangs disappear as well as for the arrival of the new firmware followed by some more testing. However, when Im confident with it, the next step is to put the XT HHDD into the X61s which is used primarily for travel purpose.

Why wait? Simple, while I can tolerate a reboot or crash or data loss or disruption while in the office given access to copies as well as standby or backup systems to work from, when traveling options are more limited. Sure if there is data loss, I can go to my cloud provider and rapidly recall a file or multiple ones as needed or for critical data, recover from a portable encrypted USB device. Consequently I want more confidence in the XT HHDD before deploying it for travel mode which it is probably safe to do as of now, however I want to see how stable it is in the office before taking it on the road.

What does this all mean?

  • Simple, have a backup of your data and systems
  • Test and verify those backups or standby systems periodically
  • Have a fall back plan for when trying new things
  • Keep productivity in mind, at some point you may have to fall back
  • If something is important enough to protect, have multiple copies
  • Be ready to eat your own dog food or what you talk about
  • Do not be scared, however be prepared, look before you leap

How about you are you using a HHDD yet and if so, what are your experiences? I am curious to hear if anyone has tried using a HHDD in their VMware lab environments yet in place of a regular HDD or before spending a boat load of money for a similar sized SSD.

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.

Apple iPad: Is it a Business iTool or iToy?


Apple iPad via www.apple.com

With the formal release and availability of the Apple iPad (See previous post here) along with networking capabilities including 3G and WiFi, needless to say there has been plenty of buzz in the tech sphere and beyond on both what you can do, as well as what you can not do with the new Apple iProduct. Similarly, there has been buzz from Apple co-founder and chairman Steve Jobs defending why there is no Adobe flash capabilities on the iPad or perhaps a different way, attaching flash as a non standard which is ironic for those who see many Apple products as being non standard.

What has also been getting some buzz and discussions is if the iPad is a business iTool or iToy including a recent discussion on the StorageMonkeys Infosmack 48 podcast with hosts Greg Knieriemen @Knieriemen, Marc Farley @3parfarley, guest emeritus Mark Twomey @Storagezilla and Chris Weil LeBlanc @c_weil .

Also check out the StorageMonkeys weekly Tuesday Tech Fight for May 4, 2010 (May require registration which is free)

Granted like any other desktop, portable or handheld display device with a real or virtual keyboard and some type of networking interface combined with creative programming or hacks, almost anything can be used as a monitor or display or management tool interface to a variety of technologies.

That also begs the question along with others mentioned in a post a few months ago of what is the real value for the iPad today?

Certainly there are some business or organizations that simply need a very thin client for accessing public or private cloud applications, entertainment or other web content in addition to being a personal information device or digital assistant along the lines of a traditional iPod or similar device where a PC or Mac is not needed.

Likewise down the road as pointed out here, there could be other use cases (e.g. build it and they will come).

However today for business, the question remains, is the Apple iPad a business iTool or iToy or do you simply iDont Care?

Here is a link to a related post along with poll where you can cast your vote as well as see what others are thinking about the iPad.

Industry trends and perspectives thoughts on iPad for business

In case you did not hear, Apple announced the iTouch on steroids aka iPad last week.


Apple iPad via www.apple.com

Is it a phone? No, its not an iPhone

Is it a PC? Well, not in the context of the traditional PC or Mac book

What is the iPad or more importantly, what is the possible business angle?

First as to what is it, it might be easier to describe what it is not.

As mentioned above, it is not an iPhone, granted you can get an iPad with 3G or WiFi for data access (similar to how iTouch has WiFi). Likewise, the iPad is not a PC in the context of running applications traditionally found on Windows PCs or Mac devices.

Does that mean the iPad is simply an iTouch or iPod for entertainment on steroids? Well, Maybe!

What is it?
As far as what is the iPad, here is a link to its specifications, some of which have resulted in confusion. For example, I have seen many comments about how the iPad does not have a camera. Well, not built in however there is an optional external camera if you need one.

As a side note, Im curious as to the net effect of how many PBytes of storage, TBytes of network bandwidth, and ExaHertz (I made that one up) of processing cycles were consumed via downloads or people watching the news of the iPad launch?

However, Im seeing additional uses for the iPad compared to the iTouch given its larger physical screen size and data access options, even if it is not a phone. For example, I can see scenarios in education where if the publishers get on board, can make a real transition from text books to eBooks to Goggle scanned books, however given the economics involved, and the already Amazon (e.g. Kindle) vs. Apple (iPad) Elephant wars, it will be interesting to watch.

Yet another area where I can see iPads being used closer to business will be as an internet, web or cloud content access on ramps, or, portals to access cloud based applications including office suites, email, calendaring payroll, shopping among others.

Likewise I can see where iPads may have custom applications ported to them, or, made accessible via safe secure connections. In other words, there is a scenario where iPads could catch on as a truly thin lightweight multifunction PC alternative.

For some additional thoughts on possible iPad use cases, I recently did a podcast with Andrew Burton of SearchSMB at TechTarget that can be accessed here or here.

iPad receiving mixed responses
Back to the iPad which is getting mixed responses.

There have also been comments about lack of Blue tooth capabilities for the iPad. Again, there is Blue tooth support on the iPad, however the question is really about what that can be used for, or, not used for. For example, there is an optional external keyboard that is attached via docking port, however, there is still no support for Blue tooth enabled deices like my Stowaway folding keyboard. Another question I have is how would the iPad work in my Sync Blue tooth enabled F150 including for use as a turn by turn, or large screen version of moving maps similar to iPhone?

Other iPad knocks include discussions around lack of a camera, that is, if you do not buy the optional external camera. There is also talk of a lack of an Adobe Flash player (at least initially), not to be confused with some headlines that say iPad lacks flash confusing with a perceived of lack of flash SSD memory or storage (iPad actually relies on flash aka SSD memory for storage).

Yet another knock has been that while it looks like an oversize iPhone, and that it will have an optional version with 3G cell technology for communicating with web or data services, it will not be usable as a phone per say. Hmm, wonder how long it will take for Skype, Vonage or others to appear on the iPad?

One of the questions or discussion points that come up regarding iPhones and now the iPad is the impact on what some already describe as an overloaded wireless network for ATT customers which includes me. Here (and here and here) are a couple of links to recent announcements and news about what ATT has done, and will be doing including investing $2B USD to upgrade their networks.

ATT Mobility
via www.att.com

General observations:
There appear to be a couple of bandwagons with this announcement:

  • The usual its Apple or iSomething so its very significant
  • The its a SNT (Shiny New Toy)
  • And, then others who are not quite sure where it fits or why.

Of course, there are the cynics along with skeptics (not to be confused with being one and the same). Some are cynics and discount anything from Apple like their counter parts who discount anything from Microsoft or others that are not part of their preference. However there also seems to be some skepticism among traditional Apple or iSomething fans regarding the iPad, needless to say, they are not doing iCartwheels over the announcement.

I think there is an even larger audience out there waiting to see, hear and learn if there is a play for the iPad, or, if new markets and opportunities will evolve around it for example as an alternative to Kindle, as an alternative to PCs for schools, or as a cloud content on-ramp. In other words, for markets where a PC is not needed. I think that there will be custom applications written for it, similar to those seen on custom platforms used by FedEx, UPS and many others.

There is also going to be the giveaway market where vendors will use iPad as a GUI display for their systems to be more hip that the PC or alternative to giving away Kindles.


PC and Mac People Via www.apple.com

Whats the verdict?
I think the jury is still out, Im not going to race out to the first in my neighborhood to have the shiny new toy (SNT), however I see a place for using it down the road as a content access device or running apps currently on iPhones where that platform is too small.

For example, a medical device maker who runs certain apps on iPhones yet their doctors or support staff find the iPhone to be smaller than desirable may like the iPad. However, apple may need to support .NET or other open or pseudo open interfaces for the platform lest they end up with a simple browser platform.

Given that Im going to skip the first generation of iPad waiting for the next version, similar to what I have done with the original Mac, the initial Apple Mac notebook, Newton, iPod and iPhone, its going to be awhile before I have my own iPad.

Whats your take on the iPad? Cast your vote and see what others are thinking in the following poll.

Going Rouge or Rogue in IT

Given all of the hype and buzz lately around Sarah Palins new book Going Rogue, how long until we see the term or phrase used in IT? After all, we saw some jump on the cash for clunkers theme. I wonder who will be the first to jump on the Going Rogue or rogue theme bandwagon. Here are a few ideas that might stimulate some thought, or, to keep an eye out to see who jumps on the bandwagon.

Going rogue on Acadia
Going rogue on Analysts
Going rogue on Archiving
Going rogue on Automated tiering
Going rogue on Backup
Going rogue on Blade servers
Going rogue on Bloggers
Going rogue on Clouds (public or private)
Going rogue on Compliance

Going rogue on FLASH or SSD
Going rogue on Green IT
Going rogue on Hosting
Going rogue on IOV
Going rogue on iSCSI
Going rogue on Kindle
Going rogue on Managed service providers (MSP)
Going rogue on Media venues or reporters
Going rogue on Networking
Going rogue on OSD
Going rogue on Performance
Going rogue on Polls and surveys
Going rogue on RAID
Going rogue on Security
Going rogue on SOA
Going rogue on Social media
Going rogue on Tape
Going rogue on Testing
Going rogue on Thin provision
Going rogue on Training and certifications
Going rogue on Twitter
Going rogue on VCE
Going rogue on Vendors
Going rogue with Virtualization
Going rogue on Virtual machines
Going rogue on VMware or HyperV
Going rogue on VoIP
Going rogue on Windows
Going rogue with XaaS

Alright, enough is enough for now at the risk of being perceived as snarky, after all, this is also just in fun.

Lets sit back and see who comes up with something about going rogue from an IT perspective.

Did HP respond to EMC and Cisco VCE with Microsoft HyperV bundle?

Last week EMC and Cisco along with Intel and VMware created the VCE collation along with a consumption model based service joint venture called Acadia.

In other activity last week, HP made several announcements including:

  • Improvements in sensing technologies
  • StorageWorks enhancements (SVSP, IBRIX, EVA and HyperV, X9000 and others)

EMC and Cisco were relatively quiet this week on announcement front, however HP unleashed another round of announcements that among others included:

  • Quarterly financial results
  • SMB server, storage, network and virtualization enhancements (here, here, here and here)
  • Acquisitions of 3COM (see related blog post here)

The reason I bring up all of this HP activity is not to simply re-cap all of the news and announcements which you can find on many other blogs or news sites, rather I see as a trend.

That trend appears to be one of a company on the move, not ready to sit back on its laurels, rather a company that continues to innovate in-house and via acquisitions.

Some of those acquisitions including IBRIX were relatively small, some like EDS last year and the one this week of 3COM to some would be large while to others perhaps as being seen as medium sized. Either way, HP has been busy expanding its portfolio of technology solution and services offerings along with its comprehensive IT stack.

Cisco, EMC and HP are examples of companies looking to expand their IT stacks and footprint in terms of diversifying current product focus and reach, along with extending into new or further into existing customer and market sector areas. Last weeks EMC and Cisco signaled two large players combing their resources to make virtualization and private clouds easy to acquire and deploy for mid to large size environments with a theme around VMware.

This week buried in all of the HP announcements was one that caught my eye which is a virtualization solution bundle designed for small business (that is something smaller than a vblock0), something that was missing in the Cisco and EMC news of last week however one that Im sure will be addressed sooner versus later.

In the case of HP, the other thing with their virtualization bundle was the focus on the mid to small business that fall into the broad and diverse SMB category, not to mention including Microsoft.

Yes, that is right, while a VMware based solution from HP would be a no-brainer given all of the activity the two companies are involved  in as joint partners, Microsoft HyperV was front and center.

Is this a reaction to last weeks Cisco and EMC salvo?

Perhaps and some will jump to that conclusion. However I will also offer this alternative scenario, 85-90 percent of servers consolidated into virtual machines (VMs) on VMware or other hypervisors including Microsoft HyperV are Windows based.

Likewise as one of the largest if not largest server vendors (pick your favorite server category or price band) who also happens to be one of the largest Microsoft Windows partners, I would have been more surprised if HP had not done a HyperV bundle.

While Cisco and EMC may stay the course or at least talk the talk with a VMware affinity in the Acadia and VCE coalition for the time being, I would expect HP to flex its wings a bit and show diversity of support for multiple Hypervisors, Operating Systems across its various server, network, storage and services platforms.

I would not be surprised to see some VMware based bundles appear over time building on previous announced HP blade systems matrix solution bundles.

Welcome back my friends to the show that never ends, that is the on-going server, storage, networking, virtualization, hardware, software and services solutions game for enabling the adaptive, dynamic, flexible, scalable, resilient, service oriented, public or private cloud, infrastructure as a service green and virtual data center.

Stay tuned, there is much more to come!

Ok, nuff said.

MSP Business Journal Names Greg Schulz an Eco-tech Warrior

In the April 10th, 2009 issue of the Minneapolis St. Paul (MSP) Business Journal, guess who was named one of three Eco-Tech Warriors? That’s right, yours truly (See the article here).

Photo by Nancy Kuehn – MSP Business Journal

What can I say, I’m flattered and appreciate the coverage. Besides seeing the finished article in the special report, the real fun was doing the photo shoot with the props including the heavy swords, those were not plastic (Hummm, Iron Chef?)!

The photo shoot with the other two “Eco-Warriors” Tom Diamond of New Boundary Technology, and Travis Pakonen of Encompass Solutions along with Nancy Kuehn our photographer as well as the artistic and project management folks from MSP Business Journal were an absolute blast to work with.

For those of you looking for policy management as well as energy management tools for desktops, workstations and PCs, checkout Tom Diamonds New Boundary Technologies and their solutions. Likewise, I hear good things from friends who have used the services of Travis Pakonen and N’Compass for their data center projects.

Ok, nuff said.

Protecting and Storing Personal Digital Documents

Storage I/O trends

Cindy Waxer recently wrote a great article over at Bankrate.com that also appeared on CNBC.Com among other venues titled 5 digital ways to store money documents that includes commentary and industry perspectives by yours truly Greg Schulz.

Why the concern about safely and securing personal digital documents? Digital created or stored data ranges from income tax, social security, mortgage and fiance, on-line and electronic bill payments, credit cards as well as banking and retirement information that is being stored on personal computers in place of, or in addition to printed hardcopy forms.

Many organizations are encouraging consumers as well as business to shift from printed hardcopy invoices and bills towards using electronic and paperless bill payments. In some instances, organizations offer discounts for switching to electronic bill payment or transactions while others apply service fees for using traditional non electronic payment methods.

So again, why the concern about storing safely and securely your digital receipts, invoices and payment records, after all, since they are on-line, why not simply rely on whom ever you are dealing with to maintain those records? The answers are many ranging from simple availability of having ready access to your documents similar to why you would have copies of important hardcopy documents available in addition to being in a safe place. Another answer is for compliance, long thought to only the realm and area of focus for large financial institutions.

So what is one to do? Simple, protect important electronic documents as you would protect important hardcopy documents by making copies and storing them in safe secure places including off-site archives in a different location.

Some general tips, technologies and techniques for safely storing digital documents include:

  • Make multiple copies of important data files, documents, photos or other important items
  • Store copies of important files and data on encrypted removable media including placing copies off-site
  • Protect encryption keys and passwords in a safe place to unlock protected data when needed
  • Leverage removable media including disk drives, USB FLASH thumb drives, CD/DVD or magnetic tape
  • Utilize on-line web or cloud based managed service providers offering internet document storage
  • Talk to your bank to see what they offer for digital safe deposit boxes also known as cloud or managed storage services
  • Perform regular backups of computers data files as well as have a disaster recovery kit and CD (or disk drive) stored in a safe place

    • Of course there is the question of how do you know what is important and what is not important, again, what has value to you either from a financial or legal perspective as well as soft value for example priceless digital or scanned photographs, video and recordings among other sentimental documents.
