Top 10 Reasons to Use IBM for VM Deployments


 

IBM @ VMworld 2011

After a full first day at VMworld, I started to think more about IBM and their technology solutions that help customers in a VMware environment.  Here is a top ten list of things to consider when looking at a VMware implementation and how IBM can help.

#1 Integration

VMware is playing Switzerland and ensuring all vendors are on a level playing field, so when other vendors state that they have “better” or “closer” technology integration than other vendors its probably not true.  Some vendors may not choose to integrate with certain things, but rest assured, all of   VMware’s APIs are open to all vendors.  Take a look and see how IBM is providing plug-ins for vSphere, SRM, and VAAI in XIV as well as other storage platforms.

#2 Ease of Use

IBM has seen, firsthand, a number of our customers switch from different competitive platforms to XIV because of the simplicity of the XIV solution.  A large manufacturer is one example of a customer who is provisioning new VMware instances in less than five minutes with XIV. 

Another XIV customer, who is a very experienced storage administrator, saw the XIV GUI and quoted "I don't get it (XIV GUI).  It can't be that easy.  Either I'm missing something or they are not showing me everything."  Well, the reality is, it is that easy and that interface is prolific throughout the IBM storage portfolio including the Storwize V7000 and SVC.

#3 Storage Efficiency

Probably one of the most important topics this year is Storage Efficiency and IBM is a leader in this department.  The N-Series with the Real-time Compression appliance can reduce the VMware storage footprint up to 75%.  Users tell us that by implementing VMware, their storage footprint has grown by as much as 4x.  Therefore their overall IT budgets didn’t get better, the dollars just shifted from servers to storage.  IBM’s Real-time Compression users can save up to 75% without any performance impact.  Additionally, Real-time Compression is the only compression technology that works in conjunction with deduplication, compressing the data before it is dedplicated, giving an added benefit to the technology.

Data Protection, Retention and Archive Starts with Data Value


It feels good to open up the blogging again to new topics, especially ones I am intimately familiar with.  (But have no fear, there will be references to primary storage optimization / compression.)

This weekend I had an interesting conversation with my Dad.  We were discussing backup.  My dad basically runs IT for the State of Maine.  The State of Maine uses CommVault backup software.  So I posed the question to him, “What would it take for you to rip out CommVault and replace it with another solution.  He thought about it for a moment and replied “I wouldn’t”.  His answer came down to a couple of reasons.

First was the expense.  It’s not just about buying the new software, it would be training people to run the new software and it would be about throwing away the massive investment they have in their existing product as well as converting all the years of backup takes created with one software to the new software.  This is one of the biggest things vendors forget when trying to sell a customer on their backup software.

Second was the fact that, feature for feature, the top 5 traditional backup software products are not really that different from one another.  Sure, I do agree that some products have features that others don’t, and others products have features that work better than others, but in reality, the delta is so small and the workarounds are so simple it doesn’t really matter.  Unless your replacing traditional backup software with an evolutionary source based data deduplication software (which is only applicable for some environments) there is no advantage to switching software.

The challenge is if Data Protection is still one of the biggest and most expensive pain points within IT, how do the problems get resolved if replacing the software controlling it all is too costly to change?

Compressed Thoughts – Compression and Deduplication


This video doesn't talk about the merits of one versus the other but how when compression (or capacity optimization is done right) it should enhance data deduplication, not impact it.  Enjoy and for more videos like this one go to the StorwizeChannel.

Comprehensive Capacity Optimization – Deduplication 2.0


Technology is great isn't it?  When someone thinks they have a new idea on the same old technology foundation they call it "X 2.0".  I have been watching the banter between analysts and vendors (specifically NTAP’s Dr. Dedupe and Permabit’s CEO Tom Cook) on the topic of Deduplication 2.0 and it is my belief that the proverbial boat is being missed (since we are using water analogies).  I have been watching these guys hash it out for the past few weeks and decided I have to jump in.  I find the real value to these conversations is the value to the end user.  At the end of the day, it doesn't really matter who 'coined' or 'invented' a term (like deduplication 2.0) but what does matter is if  the term actually helps describe a technology and how that technology can be leveraged to make things better in the data center.  We should focus on the implications of this new generation of deduplication - ‘deduplication 2.0’.

In May I delivered a presentation to a number of EMC customers on the topic of Data Deduplication 2.0 - Comprehensive Capacity Optimization.  The point of my presentation was simple (and keep in mind this was before the Data Domain acquisition); there are a number of capacity optimization technologies/capabilities that are available to customers today.  Originally these deduplication technologies were used primarily for backup purposes but slowly, deduplication is making its way into primary storage. Deduplication in primary storage makes a lot of sense FOR DATA THAT IS STATIC.  Why only static data?  Static data is data that isn't used frequently (doesn't mean it's not important, it just simply is not accessed often); because access to this data is infrequent, the performance requirements for this data is less than that of active data. Remember; nothing in IT is free.  If I deduplicate data, in order to use it, I must ‘rehydrate’ it and thus there is a performance implication so I want to be careful where I deduplicate data so as not to inhibit performance on production data.

The Side Effects of Backup on Server Virtualization


Server virtualization has changed the IT landscape dramatically.  It has become a magic potion curing a number of ills in the physical server world such as low individual CPU utilization and excess use of space, power and cooling in the data center.  However, like all potions that cure what ails you, there can be side effects.  You need to be careful of what the Witch Doctor orders.

When I speak with customers who have aggressively implemented a virtual server infrastructure, 9 out of 10 will tell me that they underestimated the affect that virtualization would have on their backups and backup process and how backup might actually make virtualization less of the magic potion they had hoped, when not considered during the virtual server assessment and planning process.  So what is the issue?  Backup is a virtualization bottleneck, and without addressing it, you may not be able to obtain the server consolidation ratios you had been expecting which can have a negative effect on your virtual server TCO and ROI.

This is a timely discussion as VMworld has just concluded.  VMware users flocked to VMworld looking for best practices when it comes to implementing virtual server technology.  Because virtualization allows IT to reduce the overall physical hardware infrastructure, users will be looking at how to maximize their server consolidation ratios (get as many virtual servers on a physical server as they can and still provide good application performance).

I often hear that companies assess their environments by looking at the production applications on their physical server environment, identify their work loads and translating that into some consolidation ratio of physical servers to virtual servers.  I also hear, from these same customers, that backup was never taken into consideration during the assessment phase when trying to identify the best possible consolidation ratios.  These customers implement their new virtual server environments, install the backup agent they had previously been using for physical server backups and attempt to backup their virtual servers and they find that they would only be able to protect 50% to 60% of the new environment.  Why?

A Data Proteciton Reference Architecture – Part 4


Business Critical Applications

The tip of the triangle focuses on the applications (or data) that drives your business.  It is these applications within your business that, should they go down for any length of time, cost you money.  The recovery of this information, in the event of a ‘disaster’, needs to be very fast (RTO in minutes) and the data can’t be very ‘old’ when it is recovered (short RPO, less than 24 hours).   Typically,  the technologies that are used for these types of applications are replication (synchronous or asynchronous) or continuous data protection (CDP).  These technologies ensure that recovery at the alternate location  are instant (or near instant) and / or give users the ability to pick a point in time they want to recover to in order to ensure no data loss and the ability to bring up the applications as fast and accurately as possible.  This category, much like the rest of them, have the same disclaimer, 'one size (product) does not fit all'.  Depending upon the value of the data in this tier, and the risk to the business if this data is unavailable drives the technology and spend in this part of the triangle.  Keep in mind, the right technology (Don't choose CDP if you need an active remote file system) gives you the best recovery (RPO) for your business needs and can keep you on the Road to Recovery.

EMC World Kicks Off with Clouds and Virtualization


EMC World kicked off this morning first with a presentation from yours truly on Data Deduplication 2.0 - Comprehensive Capacity Optimization.  We discussed how data deduplication 1.0 is morphing into all areas of EMC's storage ecosystem in order to optimize capacity everywhere.  I talked about data deduplication as well as single instancing and compression are technology components that will help EMC achieve this goal.

Next Joe Tucci spoke in his keynote about how data deduplication as well as compression are key technologies for the data center of the future and how these technologies will aid in delivering a more efficient cloud computing strategy.  Not only will these technologies help in building out a cloud infrastructure, they will also help to protect a cloud infrastructure (which is what we are all about here).

Finally, Paul Maritz gave his keynote on how the virtual infrastructure will help to fulfill the goals of a private cloud.  He also discussed that it is time to invest in software and people and not hardware as VMware continues to drive value into their software to help make your data center, better, smarter, stronger and faster for less.

Each of these initiatives will have an impact on how data is stored and ultimately protected but new storage services will enable more efficient storage and protection across the virtual data center and the cloud and ultimately take backup beyond and put you on the road to recovery.

Stay tuned for more updates about the show.
