IBM Spectrum Virtualize Reviews

The product helps us to manage our storage in a way that allows us to put different frames inside or out of our storage infrastructure and migrate.

The benefits are that it speeds up provisioning of the storage across different tiers and allows a small team to manage that function, for many petabytes of data.

I think they are doing a good job with the features that are there. I don't really have that much to add for the next release. I like what we see.

Stability has been outstanding. There are failures, but they are designed to have failures, and we have not had a single data loss incident, even throughout some pretty funky upgrades.

We are SVC customers and we would like to see the ability to add more nodes. After some sessions that we've had this morning, now we're understanding why this hasn't happened, but we still have hope that it will happen. We will be able to go from an 8-node cluster up to maybe a twelve or fourteen. It would make us really happy.

For this platform, the technical support has been great. We have had very few issues that haven't been resolved, in a timely fashion.

The expense for support and maintenance is a little bit on the heavy side.

I have been involved in the initial setup process. We have production in the DR clusters, some of the production clusters have been in place prior to my arrival, but we have done the same thing in DRs.

The setup was very straightforward. We also have a guy who we call as “our good luck charm”. He is our reseller who comes to help us out; when he is not there things don't go as good, but when he is there he doesn't do much besides bring us the food and gives us great advice. They provide good, reliable support and he is a great guy.

In regards to the vendor selection, it's a price versus reward scenario. We have to be very conscious of what we spend and we have to make sure that the company is spending their money well. So, we're able to buy the products that allow us to have uptime.

If you can afford it, get it. It's great.

It provides a control plane for the data plane. With Spectrum Virtualize, you can extract the physical storage, then hide it and give it flexibility.

Most of my implementations have been on-premise. We could stand up a software instance someplace else and connect to it. However, most people that I work with get it in an appliance format. They use it to migrate off of existing storage. When lease expiration of something is occurring, they will use it to save value and migrate everything. Then, I will see them in a traditional Fibre Channel, a SAN connected to server architecture, or both in virtualized servers as well as standalone.

I do not personally manage any instances, but I have several dozen customers that I have deployed this solution for, so it is up and running in their production.

It lowers cost. It does so by getting more efficient use out of the technology behind it. 

It also simplifies access. You set it and forget it for a lot of things.

• Ease of use
• Scalability 
• The product comes in hardware, software, and appliance models, so I have a lot of choice on how we deploy it and its interoperability.

Tighter integration with cloud storage might be useful as a target for a variety of use cases. 

Stability is very good. I have been working with the product for probably 15 years. I have put it in production during critical workloads without a problem.

The scalability is very good. It can handle anywhere from very small to large enterprise class.

It can handle our customers' future growth. The hardware behind it may get more commoditized, but the capabilities of Spectrum Virtualize remains the same. It still provides value.

Technical support is very good. Most of the support personnel that I have talked to were very knowledgeable, which has always been good.

Originally, it was probably complex. Now, it is straightforward. It is pretty easy to deploy, and with a basic understanding, it comes together easily.

Our customers usually evaluate Dell EMC and Hitachi, but also some of the other newer flash environments, like Compellent. 

I would recommend Spectrum Virtualize. Across the industry, nobody matches it.

Do your homework and architect the solution upfront. The technology will stand by itself if you have done it right.

Customers' main criteria when selecting a solution: Most of my customers buy it in the appliance format, whether it is a Storwize product or something else. They are competitively shopping products, so cost is important along with scalability and usability. They typically start to believe once they see the interfaces, and they like the usability side of it. A lot of my customers have been dissatisfied with other vendors, so this is a rallying point for them. I do not have anybody who has been sorry.

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.

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.

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.

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.

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.

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.

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.

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.

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.

I would absolutely recommend it. I would ask them, "Why are you waiting?"

We use this solution to run our virtual machines.

The ability to add the virtual machine on the Spectrum environment to sort out the data movers(DMs) and their schedules is a valuable feature. You are able to have, for example, four data movers to balance them so you do not have too much work on one data mover.

Once you know how to run the commands it tells you what has been backed up and which DM did not get backed up. You have what you call DSM errors. The system talks to the schedule and then it knows why and what happened with a certain backup that was not completed. When you are trying to troubleshoot you are able to go back to the DSM or OPT error files and scroll down and see why the backup did not run. It gives you the error number allowing you to go back to see what the issue was.

When comparing this solution to others it is running 1.5 but should be on a 2.0 and the difficulty is a little higher to operate at first which could be improved.

The only errors I find sometimes is the solution tells me I cannot operate it because a service has turned off, you can just go back to the VM, go to services, and turn back the services. However, this should improve.

We use the solution to backup data.

I have found the solution to be very stable.

There is no maintenance required because it runs very smoothly.

This solution came as an additional cost for the TSM package we chose.

I have evaluated Cohesity, Veeam, and Commvault.

My advice to those wanted to implement this solution would be it is very useful and will give you all the details you need; how to set up the data movers, make sure they are balanced so that the load is distributed evenly, how to set it up and get all the documents in place once you log in.

I rate IBM Spectrum Virtualize an eight out of ten.

The product is very flexible, and it is very easy to add any additional product from the background; so we can use any multi-vendor backend storages and virtualize the product. It becomes a powerful virtualization engine for migrating data, for provisioning data and any type of data migration is easy.

As I have mentioned, the benefits of this solution are that it reduces time.

Basically, we can clear the storage for faster/medium/slower access. We can make three-tiers and migrate the data easily.

The IBM Easy Tier works on different pools of disks and flash. Going forward when everything is Flash storage and no more spinning disks, the Easy Tier is not required. After attending the IBM Tech U, IBM is focusing on all flash storage devices. This is good and hopefully IBM pricing will have an edge over the competition.

Stability is awesome; it's very stable.

The scalability is absolutely outstanding and we can scale as much as we want.

IBM technical support is awesome.

Basically, we had different islands of storage from different vendors. We wanted a product to integrate all of them together. So that is why we found, IBM Spectrum Virtualize, as the product.

They come to us every time when there is an initial setup, they help us with the process. The setup is very straightforward.

We have another EMC brand storage product also, but we are using both of them.

Of course, the product is the most important criteria for vendor selection.

This is an absolutely outstanding product and anyone can use it with ease. It can do everything.

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.

The benefits are protection of data, usability, and performance speed in a high capacity setup.

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.

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.

The scalability is very good. It is about even with the open system offerings.

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.

The initial setup was complex, but that's what keeps me employed. So, it's quite all right.

It's the best mainframe storage available. It is much better than EMC and other competitors.

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.

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. Last summer, we replaced four petabytes of aged storage arrays. They were old and past end-of-life. But we did that seamlessly, without affecting any of the server applications. There were no system admin times; nothing required at all. It was really quite good for our client. That was perfect for them.

Our team operates four 8-Node IBM Spectrum Virtualize (SVC) clusters (32nodes total), two clusters at one site and two at a sister site with replication between the two sites.

These four clusters have a number of storage arrays behind them to yield a total storage capacity across the four cluster of approximately ~6 petabytes of Platinum, Gold, Silver and Bronze Data Classes. The Storage Cloud uses IBM's EasyTier feature to create different performing storage classes and uses Thin Provisioning to lower our clients requested 8 petabytes of capacity to a much less costly 5 petabytes of consumed capacity. The remaining ~1 petabyte is elasticity which is built into the Cloud.

Our client does not have any classical maintenance windows where systems or storage can be taken down for upgrades, repairs, expansion, or replacement. Servers require 24x7x365 data access (actually 4 days are planned power outages for power testing - but no IT changes are permitted).

So when I say our storage services to our client were provided continuously - non-stop - for 12 months, it means that all customer servers had 100% uninterrupted, online SAN access to their data 24x7x365 (minus the power down). During that time, our team provided on-demand capacity provisioning of about 700TB of new client growth and expansion, updated all cluster softwares, decommissioned ~4 petabytes of aging storage arrays, installed ~5 petabytes of new replacement / expansion arrays, and repaired a couple failed components. It really shows the power, utility, versatility and availability of our Cloud Storage design.

The second feature that it is software-defined. Every year, we select a new release and we get new features. This gives us time to test them out. It's just very amenable to our type of delivery of services to the clients that use storage.

In addition to that, they've been able to add some really cool functions. It started out with the usual stuff, such as thin provisioning. Then they added features like compression. Now they're actually adding transparent cloud tiering, so they can put data up in the cloud, just by taking it off of the SVC and sending to the cloud. This is very, very good for us in being able to put together a roadmap for functions for our clients of what they can do with their data.

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. So, it's okay if you have 50 volumes, and I can watch them. I can assign people to watch them. But when you have 5,000, it's not possible anymore. So you need capabilities within the products that would do what that person would've done watching the 50. So, they have this “cognitive IT” sort of thing going for them.

I don't think they've realized they can apply that cognitive concept to that. It is like, "Okay, I'm going to use software to watch all that." Now, they have some of that already with Easy Tier that automatically moves data around. It is perfect. Now I need that same concept extended into other areas.

The stability is very good. We just finished running non-stop for one year. It was perfect, with no down-time at all. Zero. 100% availability.

Scalability is perfect. We're at the top of their scale though. Right now, the largest cluster they use is eight. We have eight very high performance servers running the software. That is good, but we added a second cluster to do more, which has worked quite well. You sort of wonder, “Would it be better to have a 10 node, a 12 node, or a 16 node?”

We do use technical support. They do very good work. Because we're so big, they have a little bit of trouble tracking all the products and making sure we get connected with the reports, but, in general, they are very good.

We did a fairly extensive industry search about five years ago, when we were deploying this call initially. We were not using a different product. It was a new offering; Greenfield. We looked at all the major players in the industry and selected IBM.

When selecting a vendor, first the product has to meet future functionality. It needs to have some stability in the industry. It needs to have some past performance proof-points. Our client is somewhat risk averse, so they don't want to be first. That's very important.

I was involved with the initial setup. It was very straightforward. Delivery of all the services has been very methodical and well defined.

We looked at Hitachi, EMC, and NetApp. The major boys.

If you're going to implement this, we have a highly technically skilled team. We hired them and put them together for this purpose. So, if you're in a traditional environment without this, either hire a service like us to come in and help you get started and get “flying lessons”.

Once you're good and once your team is good, once your staff is up to speed, then they can take over if they want. This usually takes about a year. We offer a one year set of services. Afterwards, they can take over if they want to, or they can keep the service there. Once they're there, they'll never look back. It's one of those kinds of things and it's very good the way it works.

It enables us to virtualize the entire data center for the Internal Revenue Service. We have about seven or eight terabytes of data behind SVC right now. Before we took this over as a managed service, they had about 120 silo storage areas. Right now, everything is virtualized behind SVC.

It is easier for management with end of life erase. It now takes us less than two-three days to decommission the erase. It has given us an increase in the usage rate on the SVC. It has gone up from probably 30-40% on the silo erase to about 85%.

We have reduced a lot of power and cooling requirements in the data center. We have optimized as much as possible. Right now, it's running very smoothly.

I would like to see data obligation and some features like cluster grouping. I have seen that on the roadmap for the last two years, but it hasn't come out yet. They are still showing it on the roadmap, so I think that it's going to come out soon.

We've had some issues with the production rate behind SVC. We had problems with back-end storage areas having double disk failures. It took a while to recognize errors, due to some of the environmental settings within the data center. When the temperature increased, we started seeing more drive failures on the back-end. But over the last 18 months, we've had zero downtime across the board.

Scalability is very good.

Technical support is very good. We touch base with the IBM house development team in the UK once every quarter to review the roadmap. So it's very good.

The initial setup was straightforward.

We evaluated the Hitachi RV series. I think it was Z100 at that time, and IBM SVC. We tested three solutions and chose IBM SVC to virtualize the environment.

We were looking for stability, such as in the features search and the ease of manageability compared to other products. These products included EMC, Hitachi, and Red Hat.

It's easy to implement. Just become a partner with IBM and you will be successful.
