I like all the features, but the most impressive recently has been the introduction of IBM's Flash Core Modules. They are a form of a flash drive, but they have many more features.

One of the main features of Spectrum Virtualize is it virtualizes the servers from the storage. We have a very large infrastructure. A major advantage is when you get the aged storage arrays and you have to replace all of those.

It's got full features, so we can compress volumes. We can do thin volumes and we can change them on the fly.

There are many benefits to this solution. Storage virtualization and the ability to migrate massive amounts of data to other systems without impacting your client are the most valuable. It is non-disruptive for my users. We migrated 350 terabytes of data in one night to a new machine without a small system going down and a single user complaining about the performance. You have to fine-tune a lot of storage machines constantly for performance and for making sure that they are optimal, but IBM Spectrum Virtualize does this by itself. It does the adjustment on its own, and it does it right. That's what makes it different. I had a huge VSP from Hitachi, which is also a type of virtualization-based engine but with a decent size. It was a continuous performance-tuning exercise. I never had that issue with IBM Spectrum Virtualize.

It has the ability to seamlessly move hardware in and out as we refresh technology.

Using SBC, a valuable feature is the mirroring, which is the virtualization of the disk between disparate places.

The abstraction flair and the abstraction layer. We had a mixture of different storage arrays, and the wonderful thing about SVC is is that it normalizes all it into a single driver. A single view that all hosts see simultaneously.

Migration from configurations where servers have storage provisioned from older SAN disk systems to newer storage systems is almost seamless using image mode migration techniques, with only a short outage of the servers.

The ability to have a feature-rich software set which extends the capabilities of the back-end storage arrays.

The most valuable feature is its reliability.

t is limited in terms of a single system to eight nodes or four, what they call IO groups.

There are things that occur when you get to this size and capacity. We're very large, i.e., petabytes. When you get to that sheer volume of the numbers of things, it is too big for people to keep track of.

The integration would be an option that we would like, but I understand that's not how it's going to be implemented.

I hate I/O groups. If you start swapping I/O groups, they can be potentially risky. If they could get rid of the whole I/O group principle, the risk is not there anymore. I understand the fundamental thing about I/O groups, but they are risky.

For improvement considerations, I would probably say multiple sites.

NBME support and support for a higher Fibre Channel lengths could be improved, but those are already on the roadmap.

They are actually working on one bug we found, which was with flash restore. This was the user interface design for virtual environments.

I already discussed possible improvements with some of the guys from Hearnsley. One of our frustrations is when you go to expand volumes in a global mirror environment, you have to stop everything in order to expand. So that's one of the things.
