Cloud conversations: Loss of data access vs. data loss

Have you hugged your cloud or MSP lately?

Why give a cloud a hug and what does it have to do with loss of data access vs. loss of data?

First there is a difference between actually losing data and losing access to it.

Losing data means that you have no backup or copy of the information thus it is gone. This means there are no good valid backups, snapshots, copies or archives that can be used to restore or recover the information.

Losing access to data means that there is a copy of it somewhere however it will take time to make it usable (no data was actually lost). How long you have to wait until the data is restored or recovered will vary and during that time it may seem like data was lost.

Second, industry hype for and against clouds serves as a lighting rod for when things happen.

Lighting recently struck (or at least virtually) with some outages (see links below) including at Google Gmail.

Cloud crowd cheerleaders may need a hug to feel good while they or their technology get tossed about a bit. Google announced that they had a service disruption recently however that data was not lost, only loss of access for a period of time.

Lets take a step back before going forward.

With the Google Gmail disruption, following on previous incidents, true cynics and naysayers will probably jump on the anti cloud FUD feeding frenzy. The true cloud cynics will tell the skeptics all about cloud challenges perhaps never having had actually used any service or technology themselves.

Cloud crowd cheerleaders are generally a happy go lucky bunch with virtual beliefs and physical or real emotions. Cloud crowd cheerleaders have a strong passion for their technology or paradigm taking it various serious in some instances perceiving attacks or fud against cloud as an attack on them or their belief. Some cheerleaders will see this post as snarky or cynical (ok, get over it already).


Ongoing poll at StorageIOblog.com, click on the image to cast your vote.

Then there are the skeptics or interested audience who are not complete cynics or cheerleaders (those in the middle 80 percent of the above chart).

Generally speaking they want to learn more, understand issues to work around or take appropriate steps and institute best practices. They see a place for MSP or cloud services for some things to compliment what they are currently doing and tend to be the majority of audiences outside of special interest, vendor or industry trade groups.

Some additional thoughts, comments and perspectives:

  • Loss of data means you cannot get it back to a specific RPO (Recovery Point Objective or how much data you can afford to lose). Loss of access to data means that you cannot get to your data until a specific RTO (Recovery Time Objective).


Tiered data protection, RTO and RPOs, align technique and technology to SLO needs


RTO and RPOs

  • RAID and replication provide accessibility to data not data protection. The good news with RAID and replication or mirroring is if you make a change to the data it is copied or protected. The bad news is if it is deleted or corrupted that error or problem is also replicated.
  • Backup, snapshots, CDP or other time interval based techniques protect data against loss however may require time to restore, recovery or refresh from. A combination of data availability and accessibility along with time interval based protection are needed (e.g. the two previous above items should be combined). CDP should also mean complete, consistent, coherent or comprehensive data protection including data in application or VM buffers.
  • Any technology will fail either on its own or via human intervention or lack of configuration. It is not if rather when as well as how gracefully a failure along with fault isolation occurs and is remediate (corrected). There is generally speaking, no such thing as a bad technology, rather poor or inappropriate use, configuration or deployment of it.
  • Protect onsite data with offsite mediums including MSP or cloud backup services while keeping a local onsite copy. Why keep an onsite local copy when using a cloud? Simple, when you lose access to the cloud or MSP for extended periods of time, if needed you have a copy of data to work with (assuming it is still valid). On other hand, important data that is onsite needs to be kept offsite. Hence cloud and MSP should compliment what is done for data protection and vise versa. Thats what I do, is what you do?
  • The technology golden rule which applies to cloud and virtualization is whoever controls the management of the technology controls the gold. Leverage CDP, which is Commonsense Data Protection or Cloud Data Protection. Hops are great in beer (as well as some other foods) however they add latency including with networks. Aggregation can cause aggravation, not everything can be consolidated, however much can be virtualized.

Here are some related blog posts:

Additional links to related articles and commentary:

Closing thoughts and comments (for now) regarding clouds.

Its not if, rather when, where, why, how and with what will you leverage a cloud or MSP technologies, products, service, solution or architectures to compliment your environment.

How will cloud or MSP work for you vs. you working for it (unless you actually do work for one of them).

Dont be scared of clouds or virtualization, however look before you leap!

BTW, for those in the Minneapolis St. Paul area (aka the other MSP), check out this event on March 15, 2011. I have been invited to talk about optimizing your data storage and virtual environments and be prepared to take advantage of cloud computing opportunities as they mature.

Nuff said for now

What do you need when its time to buy a new server?

You have been told by someone or determined on your own that it is time for a new server, however what to get?

A blade server, rack mount, floor model, physical or virtual perhaps cloud?

How about one that is fully configured and accessorized to meet your specific environments needs?

There are several considerations involving what type of server or computer is needed to meet your specific needs or application requirements. Options include price, packaging, vendor preferences, blade center, freestanding, 1U rack mount, virtual and cloud support, with or without storage and networking, performance as well as power and cooling among other considerations.

Here is a link (PDF version here, may require registration) to an article that I put together to help determine your needs as well as consider various options for your next server.

Hope you find the information useful!

From bits to bytes: Decoding Encoding

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

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

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

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

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

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

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

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

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

1GB

x32 lanes

8GB

16GBs

32GB

Table 1: PCIe generation comparisons

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

Ethernet 10Gb

64b/66b

Fibre Channel 1/2/4/8 Gb

8b/10b

SAS 6Gb

8b/10b

Table 2: Common encoding

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

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

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

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

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

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

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

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

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

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

Some previous blog posts:

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

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

Nuff said for now

Securing data at rest: Self Encrypting Disks (SEDs)

Here is a link to a recent guest post that I was invited to do over at The Virtualization Practice (TVP) pertaining to Self Encrypting Disk (SEDs).

Based on the trusted computing group (TCG) DriveTrust and OPAL disk drive security models, SEDs offload encryption to the disk drive while complimenting other encryption security solutions to protect against theft or lost storage devices. There is another benefit however for SEDs which is simplifying the process of decommissioning a storage device safely and quickly.

If you are not familiar with them, SEDs perform encryption within the hard disk drive (HDD) itself using the onboard processor and resident firmware. Since SEDs only protect data at rest, other forms of encryption should be combined to protect data in flight or on the move.

There is also another benefit of SEDs in that for those of you concerned about how to digital destroy, shred or erase large capacity disks in the future, you may have a new option. While intended for protecting data, a byproduct is that when a SED is removed from the system or server or controller that it has established an affinity with, its contents are effectively useless until reattached. If the encryption key for a SED is changed, then the data is instantly rendered useless, or at least for most environments.

Learn more about SEDs here and via the following links:

  • Self-Encrypting Drives for IBM System x
  • Trusted Computing Group OPAL Summary
  • Storage Performance Council (SPC) SED and Non SED benchmarks
  • Seagate SED information
  • Trusted Computing Group SED information

What have I been doing this winter?

Its been almost a month since my last post and want to say hello and let you know what I have been doing.

What I have been doing is:

  • Accumulating a long list of ideas for upcoming blog post, article, tips, webinars and other content.
  • Recording some podcasts, web casts doing interviews and commentary along with a few articles here and there.
  • Working with some new venues where if all comes together you should be seeing material or commentary appearing soon.
  • Filling some dates for the 2011 out and about events and activities page.
  • Doing research in several different areas as well as working with clients on various project activities, many of which that are NDA.
  • Getting some recently finished content ready to appear on the main web site as well as in the blog and other venues.
  • Attending vendor events and briefing sessions on solutions some of which are yet to be announced.
  • Enjoying the cold and snowy winter as best as can be (see some videos here) while trying to avoid cold and flue season.

In addition to the above, I have been trying to stay very focused on is getting my new book which is titled Cloud and Virtual Data Storage Networking (CRC) wrapped up for a summer 2011 release. This is my third solo book project that is in addition to co writing or contributing to several other book projects.

Cloud and Virtual Data Storage Networking

Im doing the project the old fashioned way which means writing it myself as opposed to using ghost writers along with a traditional publishing house (CRC, same as my last book) all of which takes a bit more time. For anyone who has done a project like this you know what is involved. For those who have not it includes research, writing, editing, working with editors and copyeditors, subject matter experts doing initial reviews, illustrations and page layouts, markups, more edits and proofs. Then there are the general project management activities along with marketing and rollout plans, companion presentation material working with the publisher and others.

Anyway, hope you are all doing well, look forward to sharing more with you soon, now it is time to get back to work…

Nuff said for now

NetApp and Akorri: An E2E cross technology domain SRA play

The other day NetApp announced that it was planning on doing another acquisition following on their recent purchase of Bycast (policy based storage and management software).

This time, NetApp is doing yet another software acquisition of Infrastructure Resource Management (IRM) as well as End to End (E2E) cross technology domain management and Storage or Systems Resource Analysis (SRA) startup Akorri which also builds on its past acquisition of SRA solution Onaro.

Is this a good move by NetApp?

Assuming they got a good price, yes, this has very potential for NetApp assuming they can assimilate the solution as well as articulate where it fits complimenting its other management tools including SANscreen (aka Onaro).

Is Akorii a good product?

Yes, most of the customers and var partners of Akorri that I talk to have great things to say and having looked into the technology, it has lots of good potential for NetApp. However, there is a common theme around Akorri that has been its high price, something that was also heard from Onaro customers before NetApp did that acquisition. If NetApp can leverage its direct as well as partner touch to reduce the cost of sale for Akorri as well as rationalize the pricing or at least better articulate the value proposition to make it a must have vs nice to have, they can do well.

The importance of E2E awareness of IT resources across different technology domains (or focus areas) is that you can not effectively manage what you do not have timely access or visibility into. Hence the theme of session being You cannot effectively manage what you do not know about in a timely manner. I recently did a couple of Industry Trends and Perspectives webcast events around the topic and themes of End to End (E2E) awareness and cross domain (or technology) management insight for cloud, virtual and other abstracted as well as physical IT environments.

E2E Awareness and insight for IT environments

I recently did a couple of Industry Trends and Perspectives webcast events around the topic and themes of End to End (E2E) awareness and cross domain (or technology) management insight for cloud, virtual and other abstracted as well as physical IT environments.

The importance of E2E awareness of IT resources across different technology domains (or focus areas) is that you can not effectively manage what you do not have timely access or visibility into. Hence the theme of session being You cannot effectively manage what you do not know about in a timely manner.

Here is the abstract for the webcast:

Virtualization, clouds and other forms of abstraction help IT organizations enable flexible and scalable services delivery. While abstraction of underlying resources simplifies services delivery from an IT customers perspective, additional layers of technology along with interdependencies still need to be tracked as well as managed.  A key enabler for IT organizations is having end to end (E2E) situational awareness of available resources and how they are being used. By having timely situational awareness across various technology domains, IT organizations gain insight into how resources can be more effectively deployed in an efficient manner.

Join independent IT industry analyst, author and blogger Greg Schulz as he looks at common challenges as well as opportunities for leveraging E2E situational awareness to remove blind spots from efficient effective IT services delivery. Greg will look several scenarios including among others cost reduction, maximize resource usage, shrink migration and data consolidation times for cloud, virtual and traditional IT environments while maintaining or enhancing IT services delivery.

If you are interested in IT Infrastructure Resource Management (IRM) of servers, storage, IO networking, virtualization, cloud, backup or restore, optimization as well as cloud or legacy environments and metrics, I invite you to view the following web cast.

E2E cross domain awareness webcast

As the Hard Disk Drive HDD continues to spin

As the Hard Disk Drive HDD continues to spin

server storage data infrastructure i/o iop hdd ssd trends

Updated 2/10/2018

Despite having been repeatedly declared dead at the hands of some new emerging technology over the past several decades, the Hard Disk Drive (HDD) continues to spin and evolve as it moves towards its 60th birthday.

More recently HDDs have been declared dead due to flash SSD that according to some predictions, should have caused the HDD to be extinct by now.

Meanwhile, having not yet died in addition to having qualified for its AARP membership a few years ago, the HDD continues to evolve in capacity, smaller form factor, performance, reliability, density along with cost improvements.

Back in 2006 I did an article titled Happy 50th, hard drive, but will you make it to 60?

IMHO it is safe to say that the HDD will be around for at least a few more years if not another decade (or more).

This is not to say that the HDD has outlived its usefulness or that there are not other tiered storage mediums to do specific jobs or tasks better (there are).

Instead, the HDD continues to evolve and is complimented by flash SSD in a way that HDDs are complimenting magnetic tape (another declared dead technology) each finding new roles to support more data being stored for longer periods of time.

After all, there is no such thing as a data or information recession!

What the importance of this is about technology tiering and resource alignment, matching the applicable technology to the task at hand.

Technology tiering (Servers, storage, networking, snow removal) is about aligning the applicable resource that is best suited to a particular need in a cost as well as productive manner. The HDD remains a viable tiered storage medium that continues to evolve while taking on new roles coexisting with SSD and tape along with cloud resources. These and other technologies have their place which ideally is finding or expanding into new markets instead of simply trying to cannibalize each other for market share.

Here is a link to a good story by Lucas Mearian on the history or evolution of the hard disk drive (HDD) including how a 1TB device that costs about $60 today would have cost about a trillion dollars back in the 1950s. FWIW, IMHO the 1 trillion dollars is low and should be more around 2 to 5 trillion for the one TByte if you apply common costs for management, people, care and feeding, power, cooling, backup, BC, DR and other functions.

Where To Learn More

View additional NAS, NVMe, SSD, NVM, SCM, Data Infrastructure and HDD related topics via the following links.

Additional learning experiences along with common questions (and answers), as well as tips can be found in Software Defined Data Infrastructure Essentials book.

Software Defined Data Infrastructure Essentials Book SDDC

What This All Means

IMHO, it is safe to say that the HDD is here to stay for at least a few more years (if not decades) or at least until someone decides to try a new creative marketing approach by declaring it dead (again).

Ok, nuff said, for now.

Green IT goes mainstream: What about data storage environments?

I recently did an interview with the folks over at Infortrend (a RAID storage company) discussing various industry trends and perspectives including RAID, data footprint reduction (DFR) as well as Green IT including how the Green Gap.

The Green Gap is the disconnect between common messaging around carbon and environment vs. IT and business productivity sustainment challenges that continues to result in confusion along with missed opportunities.

  • There is no such thing as a data or information recession
  • Organizations of all size will continue to have to support growth in a denser fashion
  • Doing more in a denser manner also means acquiring as well as managing more usable IT resources per dollar spent
  • Optimization and data footprint reduction (DFR) expands focus from reduction efficiency to productivity effectiveness
  • Energy efficiency shifts from avoidance to energy effectiveness where more work is done to support business productivity and sustainment
  • RAID is alive however it continues to evolve as well as leveraged in conjunction with other techniques

Here is the link to the first of a two part series where you can read my comments on how many organizations are missing out on economic as well as business sustainability benefits due to confusion and the Green Gap among other topics.

Dude, is Dell doing a disk deal again with Compellent?

Over in Eden Prairie (Minneapolis Minnesota suburb) where data storage vendor Compellent (CML) is based, they must be singing in the hallways today that it is beginning to feel a lot like Christmas.

Sure we had another dusting of snow this morning here in the Minneapolis area and the temp is actually up in the balmy 20F temperature range (was around 0F yesterday) and holiday shopping is in full swing.

The other reason I think that the Compellent folks are thinking that it feels a lot like Christmas are the reports that Dell is in exclusive talks to buy them at about $29 per share or about $876 million USD.

Dell is no stranger to holiday or shopping sprees, check these posts out as examples:

Dell Will Buy Someone, However Not Brocade (At least for now)

Back to school shopping: Dude, Dell Digests 3PAR Disk storage (we now know Dell was out bid)

Data footprint reduction (Part 2): Dell, IBM, Ocarina and Storwize

Data footprint reduction (Part 1): Life beyond dedupe and changing data lifecycles

Post Holiday IT Shopping Bargains, Dell Buying Exanet?

Did someone forget to tell Dell that Tape is dead?

Now some Compellent fans are not going to be happy with only about $29 a share or about $876 million USD price given the recent stock run up into the $30 plus range. Likewise, some of the Compellent fans may be hoping for or expecting a bidding war to drive the stock back up into the $30 range however keep in mind that it was earlier this year when the stock adjusted itself down into the mid teens.

In the case of 3PAR and the HP Dell budding war, that was a different product and company focused in a different space than where Compellent has a good fit.

Sure both 3PAR and Compellent do Fibre Channel (FC) where Dells EqualLogic only does iSCSI, however a valuation based just on FC would be like saying Dell has all the storage capabilities they need with their MD3000 series that can do SAS, iSCSI and FC.

In other words, there are different storage products for different markets or price bands and customer application needs. Kind of like winter here in Minnesota, sure one type of shovel will work for moving snow or you can leverage different technologies and techniques (tiering) to get the job done effectively the same holds for storage solutions.

Compellent has a good Cadillac product that is a good fit for some SMB environments. However the SMB space is also where Dell has several storage products some of which they own (e.g. EqualLogic), some they OEM (MD3000 series and NX) as well as resell (e.g. EMC CLARiiON).

Can the Compellent product replace the lowered CLARiiON business that Dell has itself been shifting more to their flagship EqualLogic product?

Sure however at the risk of revenue cannibalization or worse, introduction of revenue prevention teams.

Can the Compellent product then be positioned lower down under the EqualLogic product?

Sure, however why hold it back not to mention force a higher priced product down into that market segment.

Can the Compellent product be taken up market to compete above the EqualLogic head to head with the larger CLARiiON systems from EMC or comparable solutions from other vendors?

Sure, however I can hear choruses of its sounding a lot like Christmas from New England, the bay area and Tucson among others.

Does this mean that Dell is being overly generous and that this is not a good deal?

No, not at all.

Sure it is the holiday season and Dell has several billion dollars of cash laying around however that in itself does not guarantee a large handout or government sized bailout (excuse me, infusion). At $30 or more, that would be overly generous simply based on where the technology fits as well as aligns to the market realities. Consequently, at $29, this is a great deal for Compellent and also for Dell.

Why is it a good deal for Dell?

I think that it is as much about Dell getting a good deal (ok, paying a premium) to acquire a competitor that they can use to fill some product gaps where they have common VARs. However I also think that this is very much about the channel and the VAR as much if not more than it is just about a storage product. Servers are part of the game here which in turn supports storage, networking, management tools, backup/recovery, archiving and services.

Sure Dell can maybe take some cost out of the Compellent solution by replacing the Supermicro PCs that are the hardware platform for their storage controllers with Dell servers. However the bigger play is around further developing its channel and VAR ecosystems, some of whom were with EqualLogic before Dell bought them. This can also be seen as a means of Dell getting that partner ecosystem to sell overall, more dell products and solutions instead of those from Apple, EMC, Futjisu, HP, IBM, Oracle and many others.

Likewise, I doubt that Mr. Dell is paying a premium simply to make the Compellent shareholders and fans happy to create monetary velocity to stimulate holiday shopping and economic stimulus. However, for the fans, sure, while drowning your sorrows in egg nogg of holiday cheer that you are not getting $30 or higher, instead buy a round for your mates and toast Dell for your holiday gift.

The real reason I think this is a good reason for Dell is that from a business and financial perspective, assuming they stick to the $29 range, it is a good bargain for both parties. Dell gets a company who has been competing with their EqualLogic product in some cases with the same VARs or resellers. Sure it gets a Fibre Channel based product however Dell already has that with the MD3000 series which I realize is less function laden then Compellent or EqualLogic; however it is also more affordable for a different market.

If Dell can close on the deal sticking to its offer which they have the upper hand on, execute including rolling out a strategy as well as product positioning plan. Then educate their own teams as well as VARs and customers of what products fit where and when in such a manner that does not cause revenue prevention (e.g. one product or team blocking the other) or cannibalization instead expanding markets, they can do well.

While Compellent gets a huge price multiple based on their revenue (about $125M USD), if Dell can get the product revenue up from the $125 to $150 million plateau to around $250 to $300 million without cannibalizing other Dell products, the deal pays for itself in many ways.

Keep in mind that a large pile of cash sitting in the bank these days is not exactly yielding the best returns on investment.

For the Compellent fans and shareholders, congratulations!

You have gotten or perhaps are about to get a good holiday gift so knock of the complaining that you should be getting more. The option is that instead of $28 per share, you could be getting 28 lumps of coal in your Christmas stocking.

For the Dell folks, assuming the deal is done on their terms and that they can quickly rationalize the product overlap, convey and then execute on a strategy while keeping the revenue prevention teams on the sidelines you too have a holiday gift to work with (some assembly will be required however). This also is good for Dell outside of storage which may turn out to be one of the gems of the deal in keeping or expanding VARs selling Dell based servers and associated technologies.

For EMC who was slapped in the face earlier this year when Dell took a run at 3PAR, sure there will be more erosion on the lower end CLARiiOn as has been occurring with the EqualLogic. However Dell still needs a solution to effectively compete with EMC and others at the higher end of the SMB or lower end of the enterprise market.

Sure the EqualLogic or Compellent products could be deployed into such scenarios; however those solutions are then playing on a different field and out of their market sweet spots.

Lets see what happens shall we.

In the meantime, what say you?

Is this a good deal for Dell, who is the deal good for assuming it goes through and at the terms mentioned, what is your take?

Who benefits from this proposed deal?

Note that in the holiday gift giving spirit, Chicago style voting or polling will be enabled.

Ok, nuff said.

Who is responsible for vendor lockin?

Who is responsible for vendor lockin?

data infrastructure server storage I/O vendor lockin

Updated 1/21/2018

Who is responsible for vendor lockin?

Is vendor lockin caused by vendors, their partners or by customers?

In my opinion vendor lockin can be from any or all of the above.

What is vendor lockin

Vendor lockin is a situation where a customer becomes dependent or locked in by choice or other circumstances to a particular supplier or technology.

What is the difference between vendor lockin, account control and stickiness?

Im sure some marketing wiz or sales type will be happy to explain the subtle differences. Generally speaking, lockin, stickiness and account control are essentially the same, or at least strive to obtain similar results. For example, vendor lockin too some has a negative stigma. However vendor stickiness may be a new term, perhaps even sounding cool thus it is not a concern. Remember the Mary Poppins song a spoon full of sugar makes the medicine go down? In other words sometimes changing and using a different term such as sticky vs vendor lockin helps make the situation taste better.

Is vendor lockin or stickiness a bad thing?

No, not necessarily, particularly if you the customer are aware and still in control of your environment.

I have had different views of vendor lockin over the years.

These have varied from when I was a customer working in IT organizations or being a vendor and later as an advisory analyst consultant. Even as a customer, I had different views of lockin which varied depending upon the situation. In some cases lockin was a result of upper management having their favorite vendor which meant when a change occurred further up the ranks, sometimes vendor lockin would shift as well. On the other hand, I also worked in IT environments where we had multiple vendors for different technologies to maintain competition across suppliers.

As a vendor, I was involved with customer sites that were best of breed while others were aligned around a single or few vendors. Some were aligned around technologies from the vendors I worked for and others were aligned with someone elses technology. In some cases as a vendor we were locked out of an account until there was a change of management or mandates at those sites. In other cases where lock out occurred, once our product was OEMd or resold by an incumbent vendor, the lockout ended.

Some vendors do a better job of establishing lockin, account management, account control or stickiness than compared to others. Some vendors may try to lock a customer in and thus there is perception that vendors lock customers in. Likewise, there is a perception that vendor lockin only occurs with the largest vendors however I have seen this also occur with smaller or niche vendors who gain control of their customers keeping larger or other vendors out.

Sweet, sticky Sue Bee Honey

Vendor lockin or stickiness is not always the result of the vendor, var, consultant or service provider pushing a particular technology, product or service. Customers can allow or enable vendor lockin as well, either by intent via alliances to drive some business initiative or accidentally by giving up account control management. Consequently vendor lockin is not a bad thing if it brings mutual benefit to the suppler and consumer.

On the other hand, if lockin causes hardship on the consumer while only benefiting the supplier, than it can be a bad thing for the customer.

Do some technologies lend themselves more to vendor lockin vs others?

Yes, some technologies lend themselves more to stickiness or lockin then others. For example, often big ticket or expensive hardware are seen as being vulnerable to vendor lockin along with other hardware items however software is where I have seen a lot of stickiness or lockin around.

However what about virtualization solutions after all the golden rule of virtualization is whoever controls the virtualization (hardware, software or services) controls the gold. This means that vendor lockin could be around a particular hypervisor or associated management tools.

How about bundled solutions or what are now called integrated vendor technology stacks including PODs (here or here) or vBlocks among others? How about databases, do they enable or facilitate vendor lockin? Perhaps, just like virtualization or operating systems or networking technology, storage system, data protection or other solutions, if you let the technology or vendor manage you, then you enable vendor lockin.

Where can vendor lockin or stickiness occur?

Application software, databases, data or information tools, messaging or collaboration, infrastructure resource management (IRM) tools ranging from security to backup to hypervisors and operating systems to email. Lets not forget about hardware which has become more interoperable from servers, storage and networks to integrated marketing or alliance stacks.

Another opportunity for lockin or stickiness can be in the form of drivers, agents or software shims where you become hooked on a feature functionality that then drives future decisions. In other words, lockin can occur in different locations both in traditional IT as well as via managed services, virtualization or cloud environments if you let it occur.

 

Keep these thoughts in mind:

  • Customers need to manage their resources and suppliers
  • Technology and their providers should work for you the customer, not the other way around
  • Technology providers conversely need to get closer to influence customer thinking
  • There can be cost with single vendor or technology sourcing due to loss of competition
  • There can be a cost associated with best of breed or functioning as your own integrator
  • There is a cost switching from vendors and or their technology to keep in mind
  • Managing your vendors or suppliers may be easier than managing your upper management
  • Vendors sales remove barriers so they can sell and setting barriers for others
  • Virtualization and cloud can be both a source for lockin as well as a tool to help prevent it
  • As a customer, if lockin provides benefits than it can be a good thing for all involved

Additional learning experiences along with common questions (and answers), as well as tips can be found in Software Defined Data Infrastructure Essentials book.

Software Defined Data Infrastructure Essentials Book SDDC

What This All Means

Ultimately, its up to the customer to manage their environment and thus have a say if they will allow vendor lockin. Granted, upper management may be the source of the lockin and not surprisingly is where some vendors will want to focus their attention directly, or via influence of high level management consultants.

So while a vendors solution may appear to be a locked in solution, it does not become a lockin issue or problem until a customer lets or allows it to be a lockin or sticky situation.
