Flood Affects Storage Industry


There was a great post a couple of weeks ago, with Tom Coughlin as a contributing editor, on Forbes’ news site about the floods that hit Thailand and how it will affect the disk drive market.  The great thing about the article is it truly highlights that necessity is the mother of invention.  What do I mean by that?  Over the past few “storage efficiency” has been a big topic with vendors.  Helping customers “do more with less”, especially in these stringent economic times, is key to the vitality of a number of businesses.  Technologies such as storage virtualization and thin provisioning have helped customers to slow their storage spend and get better utilization out of their existing storage.  Once customers have moved their utilization rates from 35% to 65% or 70%, time comes when new storage needs to be acquired to keep up with the growth of data.  The issue comes when there are no more disk drives to be acquired.  Due to the floods in Thailand, analysts predict that the storage industry could be 50 to 60 million units shy of the demand this quarter.  This does two things:

1)      Drives the price of disk higher, at a time when the expectation is to spend less for disk

2)      Has IT getting more creative on how they use and deploy their storage

It is the later that I want to focus on as paying more for disk is not necessarily the best option.  It is important to note that data grows for one reason, business does not stop, it needs to keep going and it is what is driving the demand on the data.

In the Forbes piece Tom talks about “a surge in new technologies because of this disk shortage” but he doesn’t cover some of the most innovative technologies that are available to help customers.  I would agree with Tom that we “could” see a surge in SSD but that would be short lived do to both supply and cost as well as a surge in tape, but these aren’t really “new technologies”.

Real-time Compression “Meets Minimum”


IBM's Ed Walsh, Director of Storage Efficiency sits down with Steve Duplessie, Founder of ESG to talk about how IBM Real-time Compression sets the bar for doing storage optimization in NAS. At the end of the day, if you can do compression in real time, without sacrificing performance and the transparency of the implementation, then why wouldn't you - given the savings you can get over traditional compression.

We all know compression is not new and it is coming as a standard feature in a number of storage systems. The issue is, each of these technologies has a significant impact on performance - both primary storage performance as well as the performance on all of the back end operations such as backups, replication etc...

IBM's Real-time Compression doesn't have any of these limitations - listen to Ed to hear more.

Top 10 Reasons Real-time Compression Provides Extraordinary Storage Efficiency


Over the past few weeks I have witnessed the proverbial mudslinging that takes place in the blogosphere when marketing feathers are ruffled.  Most recently I was reading Rich Anderson of The StorageSavvy Blog.  The article was "Compression better than Dedup?  NetApp Confirms!"

I have to agree with Rich on many fronts.  First, "When all you have is a hammer, everything is a nail."  Rich points out vendors have to sell "what's in the bag" so it is conceivable that all problems look like they can be solved with their solution.  If you look back over the last few years NTAP has always had a "me too" reputation.  Whatever the industry has, they have one too and its better.  For the last few years, while competing against Storwize, they have pulled the EMC tactic of trying to stall a market by saying, "We have optimization for primary storage with deduplication."   The reality is, you can't use it in real time, it is a resource hog, and again Rich mentions, the only use case it works well on in primary storage is VMware (and that is ONLY IF the customer stores their data outside the .vmdk file otherwise compression is much better).  Now that NTAP has compression their story has changed saying that compression on primary storage is better for most use cases.  Duh!  The folks at Storwize (now IBM Real-time Compression) have been saying that for years.  Why, deduplication is great for repetitive data sets, i.e. backup, not primary storage.  There just isn't that much repetitive data in primary storage.  Again, NTAP is trying to stall the market saying they have "in-line" compression for primary storage.  Sorry guys, not good enough.  In-line is NOT Real-time.  Rich also points out that the key characteristics of storage for customers are capacity and performance.  Patrick Rogers of NTAP has said publically that compression WILL indeed impact performance and that they even have a tool that will tell you how much performance will be impacted.  While NTAP may say compression is "free", we all know nothing worth having in life is free, you get what you pay for.  If you need the performance to do compression you are going to have to perform a major upgrade to  your filer in order to just be able to perform compression let alone try to do compression in real time.  No real savings there.

Business Outcomes are what Matters


I spent last week in London meeting with IBM Real-time Compression customers and partners and supporting the launch of the new IBM Storwize V7000 (not to be confused with the company IBM purchased a month ago).

While on this trip I met with a great colleague Matthew Yeager.  Matthew is one of the leading technologists working for ComputaCenter in the UK.  We spent a couple of hours discussing how the IT business was changing.  Once revered and dressed in shirt and tie, the IT manager now is plumber / electrician of the company.  The first to get yelled at when systems / applications / devices aren’t working, always lacking resources and always being asked to do more with less.  While the plumbing matters, everyone just expects it to work.  Like plugging in a phone to a phone jack, users expect a dial tone.

The shift in technology within IT is moving from “What does it cost?”, to “What is the business value I can achieve with this technology?”  More and more, especially as we are moving out of this recession, albeit slowly, customers are trying to figure out how to spend less in IT (as a percentage of overall revenue) but increase their business outcome.

If you read the blog post I did last week about Allianz.  The goals set forth in IT were to cut spending by 10% each year but increase overall efficiency.  How do you do that?  New technology is how you do that but it is not sold under the premise of a vendor brining in a new technology that they have developed or acquired, it is about identifying a problem: ‘Our storage growth and management of that growth is costing us too much money’, and then solving that problem with new technology that fits into the business.

IBM Day 1 – It’s Official


Between time off with the family this summer and all the work required to get done between 'signing' a deal to be acquired and 'closing' a deal to get acquired, the blog has been a bit slow.  But I am here now to tell you it is official.  Storwize is now Storwize, an IBM company.

As for myself, I am looking forward to the work of integrating the Storwize Technology into the IBM Storage portfolio.  The Storwize group will live under the STG organization under Brian Truskowski.  There is a new ground swell taking head at IBM these days all around storage efficiency.  To get a better understanding, please have a look at my new colleague, Tony Pearson's blog discussing storage efficiency.  My job will be now to evangelize how IT now needs to take a look at all of the available storage "services" (clones, snapshots, thin provisioning, replication, compression, deduplication, etc...) can help to create an overall storage solution that allows them to reduce their over all $/TB on not only capital expense, but also on operational expense.

Lets face it, data growth isn't slowing down and there is never a one size fits all solution for storage.  The great part about being a part of IBM now is that we have all the tools to pick from to architect a data storage solution, end to end, that allows customers to reduce their overall $/TB for both primary as well as secondary storage and make that storage much more efficient and work for the end user.

This is going to be an exciting time.  I am also anxious to continue the Storage Alchemist blog.  EMC, under the guise of Polly Pearson and Chuck Hollis taught me that social media is great, but social media done right, in a collaborative and thoughtful way can drive influence.  I join some of the best bloggers around from IBM.  (I have added Tony's "Inside System Storage" - It is a great read.)

Sever + Storage Optimization = Datacenter Utopia


Matt Prigge had a really great article on his InfoWorld Data Explosion blog called "VMware vSphere raises the bar -- again".  In the piece Matt makes two really important points.

1.  VMware has taken the world by storm over the past few years.  A technology that can lower both CapEx and OpEx costs and ease the burden of administration is a great thing for the data center.  And,

2.  With all the advantages of virtual server optimization, storage administration, is a big issue.

VSphere has done a lot to help the issues of storage administration (specifically storage performance for virtual servers) but that is only a part of the challenge.  Customers consistently tell us that by developing a virtualized server environment, their storage requirements have grown by as much as 4x.  The savings that have been realized by server virtualization are soon eclipsed by the need for more storage.  This  is one of the reasons it has taken a while for server virtualization to really take off in production.  In talking to customers, virtualizing a lab or test environment where data can be deleted once it is 'used' without worry is one thing, but in production, where the production data needs to be kept for a long time starts to cause issues.

Now, with all the hype around primary storage optimization, end users can couple the benefits of server virtualization with primary storage optimization to maximize their ROI in the datacenter.  The important thing to remember, just like server virtualization didn't force customers to sacrifice anything in terms of performance, availability, process and supportability, you need to look for the same thing from a storage optimization solution.

The valuable features added to vSphere around SIOC combined with the optimization capabilities from Storwize can allow IT to maximize storage performance, maximize their existing storage resources and not affect data integrity or data availability.  There is a new white paper on the combined solution of VMware and Storwize that outlines how VMware and Storwize can provide customers with the maximum ROI in the datacenter.

No More Tiers / Tears


The great thing about blogging and independence is that we can post things that add value that we want to share as long as we give the proper recognition.  One of my colleagues, Mike Dutch from the CTO office of SSG and long time SNIA member had some thoughts as it pertained to storage tiering that were insightful  so together we decided to share this post.  I hope you enjoy it.

I'm guessing that many people define a storage tier by its particular storage technology (like SATA). While this may be a useful working definition it obscures the essential notion of what a storage tier really is and leads to confusion when a new technology like data deduplication comes around.  A precise definition may also lead to some interesting innovations if we were to take a slightly different path.

Should deduplicated storage be considered a storage tier?  I would say “no” and here's why: because a technology such as deduplication can span, and optimize across all tiers.

A storage tier is storage space that has availability, performance, and cost characteristics different enough from other storage tiers as to economically justify the movement of data between it and other storage tiers based on the importance (value, performance need etc…) of the data. While storage tiers are often thought of as being tied to a particular type of hardware,

e.g.,  Flash, FC, SAS, SATA, VTL, PTL, COM (Computer Output Microfiche), or even paper, this is not necessarily the case. For example, highly available cloud or network-based virtual disks could leverage multiple technologies within their single tier.  Since a variety of technologies can be used to provide a particular storage service level, you should not think of a specific technology as a specific storage tier, but should instead evaluate what technology, or combination of technologies would deliver the availability-performance-cost point that I need for this level tier.  "SATA" is not a storage tier, it just happens to be one "technology-set" that can deliver for a single storage tier.

What Happened in Vegas, Stayed in Vegas


Well, until now.  This is an interesting story about archiving and how it could have, but didn't help a friend of mine.

Often, when speaking with customers, I talk to them about the 4 fundamental principals with regard to data protection:

  1. Assess
  2. Archive
  3. Backup
  4. Manage

The assessment phase is a multi-dimensional phase.  It's about people, process and technology.  Like with most things, the technology piece is the easy piece.  EMC has tools that allow us to scan file systems, data bases and email systems that report back a litany of information including but not limited to:

  • Number of files
  • Age of files
  • Volume of data
  • Owner of the data

Once EMC passes the information to the customer about their data, the real hard work begins.  Armed with the information, IT now has to go and speak to line of business managers in order to determine the value of the data, and how data of a specific value needs to be managed and protected.  The problem is line of business managers want everything saved forever, until IT tells them what the bill would be.  IT begins to describe the different 'classes' of service capabilities and line of business managers, who don't really care about the details (not because they don't care, they are just too busy), finally say "Just give me the highest level of protection I can get for the least amount of money."  IT now does the best they can to align their perceived value of the data, to the most appropriate backup and archive capabilities they have.

Now, in Vegas, I think we can all agree that the video surveillance has a ton of value to  the stake holders of the hotels and casinos.  The amount of debauchery that takes place in Vegas with the amount of money that is 'rolling' around Vegas, it is important to 'know what is going on' and to make sure all situations can be handled as efficiently as possible and this is where video surveillance comes into play and the more you 'save' on high speed disk, the easier it is to get to the truth or solve the mystery.
