Gives you the capability of putting heterogeneous storage systems in one management pane.
What is most valuable?
- Capability of putting lots of heterogeneous storage systems all in one management pane
- Being able to substitute them out and move between them
- The ability to put it all in one management and fix them into something that's much more usable.
It's just been handy with a lot of customers that have, over the years, developed a mess of storage.
How has it helped my organization?
It's all about manageability. The product lets you manage:
- Different sorts of systems
- The same host multi-pathing driver
- The same feature set: snapshots and replication, regardless of what system it is
Spectrum Virtualize gives you the same functionality and all the same management through the same GUI, regardless of whether you are using EMC storage, Hitachi storage, or IBM storage.
What needs improvement?
I’d like to see deduplication. IBM announced during Tech U that Storwize is adding it in the upcoming Q3 2017 code update-- same as what exists on the A9000. Duplicate blocks of data write references to pre-existing block of data, instead of re-writing the same data multiple times, thereby saving storage capacity.
What do I think about the stability of the solution?
For the vast majority of the time, it's absolutely awesome. I had a couple isolated problems with reliability, mostly related to replication, but I have been able to work through them.
What do I think about the scalability of the solution?
The scalability is actually one of the great things about the product. It is designed to be able to give you scalability with the virtualization of multiple storage systems. It's very easy to scale.
How is customer service and technical support?
I've had to use tech support quite a lot of times, because I support a lot of customers. Consultants support a lot of customers. Once you get past Level-1 support, it's generally top notch.
What other advice do I have?
Good luck finding anything that does half of what it does. When looking for a vendor, I look for reliability. I've had lots of good experiences with it. It's been a very reliable product and the feature set is something you can't get anywhere else.

We do not have to take any kind of outage to do a storage data migration.
What is most valuable?
Not having to take any kind of outage to do a storage data migration.
How has it helped my organization?
It improves a lot of functions for our clients. The high availability is the best thing. I have been working with it for 15 years, and it's one of the most stable products that IBM has.
What needs improvement?
There are a few little GUI issues and stuff like that, but nothing major. I would like to see better layout of some stuff. They kept on moving things around from version 7.4 to through version 8. They've made it a little difficult for some customers to find things.
What do I think about the stability of the solution?
The stability is good.
What do I think about the scalability of the solution?
The scalability is great too. It scales from a single I/O group to up to four.
How is customer service and technical support?
Technical support has been great. I've been using it for 15 years.
What other advice do I have?
Next to the DSA1000, it's the most enterprise thing that IBM has for storage.
Make sure that it really has all the things that Spectrum Virtualize has, where you can upgrade the hardware and the software and everything without taking any kind of outage. And that's for infinity, not just for the life cycle with that version of the product, but for each subsequent version. It's all done on the fly.
When choosing a vendor, I look for support.

Allows for disaster recovery with global mirror.
Pros and Cons
- "The most valuable features are the simplicity of use, the flexibility, and the options included. I mean, it's just a big time saver."
- "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."
How has it helped my organization?
Benefits for us are pretty much the simplicity, ease of implementation, and the ease of maintenance. Flexibility and responsiveness to customer needs are key. They are the things that allow for ease of disaster recovery with global mirror, which we use. So it's just flexibility and ease of use which are the key things that I like about it.
It helps us to reduce time, reduce complexity, and be more responsive to requests instead of taking an hour to do one volume. Now I can do one volume in less than two minutes. So that keeps the business moving forward and keeps up with the pace.
What is most valuable?
The most valuable features are the simplicity of use, the flexibility, and the options included. I mean, it's just a big time saver.
What needs improvement?
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.
It's on their roadmap to do, but as I understand, it's very complex. So that's one of the big features that we would like to see. And I'm sure other customers have been asking for it for years and years. That's probably the biggest thing that we can see.
What do I think about the stability of the solution?
Stability has greatly improved since day one. It's much easier to implement. It's not so white knuckle when you're doing upgrades and things like that. So they have come a long way.
What do I think about the scalability of the solution?
There's a lot of flexibility to it, especially with the new hardware coming out. Software always comes out with new and improved options, features, or fixes. So they're doing a real bang up job.
How are customer service and technical support?
Overall, technical support is good. It is sometimes frustrating when you supply all the information you think they need upfront and they come back and say, "Hey, we need this." So, there's some frustration to it.
Which solution did I use previously and why did I switch?
We used to have the Shark ESS, where you had to actually go in through their GUI manually to apply and create volumes at that level. You then had to have them mapped. It was more cumbersome and time consuming.
How was the initial setup?
The initial setup was overall pretty easy. And that was years ago, pretty much when it first came out. Overall, it was pretty easy to set up.
Which other solutions did I evaluate?
We didn't really consider any alternatives. We're pretty much an IBM shop, so it was like the leader when it came out. We value compatibility and price, obviously.
I'm a technician. I don't care about price per se. I am more involved in the technical advantages, ease of implementation, and stability. They are probably the key factors for me.
What other advice do I have?
I would absolutely recommend it. I would ask them, "Why are you waiting?"

We can move data where we need it to be and stick storage solutions on the back-end.
What is most valuable?
The most valuable feature for sure is the abstraction of the storage. In this way, we can basically stick any storage solution that we want on the back-end. Then we've got a rich feature set above that. We can basically move the data where we need it to be. We have a lot of control. It's a good product.
How has it helped my organization?
We're a fairly small shop, as far as the number of IT people that we have. The tool allows us to basically multiply our staff to be able to get our work done. We don't have to rely on consultants. The feature sets are usually ahead of where we need to be.
What needs improvement?
There's always room for improvement. A little lower price would always be nice. Otherwise, nothing major.
What do I think about the stability of the solution?
Stability has been very good. We're more on the conservative side, in that we are not going out and downloading the latest and greatest code. We are a couple of releases behind, but it's been very stable.
What do I think about the scalability of the solution?
Scalability has been really great. We've done refresh cycles every three years and the technology is usually ahead of where we need it to be, as far as scaling up is concerned.
How is customer service and technical support?
Technical support has been pretty good. Maybe sometimes we don't get responses back as fast as we would like, but they have always been very professional and they follow through. No major issues. It's been good.
How was the initial setup?
The initial setup was very easy.
Which other solutions did I evaluate?
For one, there are very few vendors that actually offer this product on the market. And nobody has the quality feature set that IBM has.
We were looking for quality, support, and service. These are all the normal things most companies look for.
What other advice do I have?
I'm not sure. I'd ask them why they haven't done it already.

Provides disaster recovery, replication, and multi-site setup.
What is most valuable?
The most valuable features are disaster recovery, replication, and multi-site setup. Being able to quickly recover in a disaster and knowing that your data is protected across multiple sites is important.
How has it helped my organization?
The benefits are protection of data, usability, and performance speed in a high capacity setup.
What needs improvement?
We found a gap for smaller clients. Right now, the only offering is a huge, rack-sized storage device, and no more. There was nothing that came after the DS-1600. I'd like to see a smaller form factor for smaller clients.
What do I think about the stability of the solution?
The product is very, very stable. It is much more stable than the open system configurations that we've worked with. It has the highest stability that we have seen.
What do I think about the scalability of the solution?
The scalability is very good. It is about even with the open system offerings.
How is customer service and technical support?
I have used technical support. The process to open problem management requests should be faster. Especially in a high pressure situation when things are going wrong. It would be good to just have a quicker way to get the problem out there and get a response.
How was the initial setup?
The initial setup was complex, but that's what keeps me employed. So, it's quite all right.
Which other solutions did I evaluate?
It's the best mainframe storage available. It is much better than EMC and other competitors.
What other advice do I have?
My advice would be to familiarize yourself with the levels of virtualization and understand how the product works at a lower level in order to implement it.

It helps us with automation and migration between other vendors for storage.
What is most valuable?
It is very good for compatibility and stability.
How has it helped my organization?
It helps us with the management of automation and migration between other vendors for storage.
What needs improvement?
I had some ideas for improvement, but I can't recall them at the moment.
What do I think about the stability of the solution?
For us, the stability is great. We don't have a problem with this solution. We have our own systems and we integrate with other systems. When we have stability problems because of compatibility between other vendors, the same vendor, and many solutions, we lose money because of longer implementation times.
What do I think about the scalability of the solution?
Regarding scalability, it depends. We had some problems with performance on all-flash storage. We don't use Spectrum Virtualize to offer storage, because they are too intensive for this environment.
How is customer service and technical support?
I have used technical support. It was hard work, but we had some colleagues in IBM and they helped us to move forward.
What other advice do I have?
They should test the solution before starting the implementation. Sometimes IBM documents something, but in the real world, it doesn't work. It depends on the brand or the version of the software. So they should test it and then go to the client to make sure that it works there.
