Good deduplication features and stability
Pros and Cons
- "The feature I find most valuable, is the deduplication, because the nature of the data that we are using in our current environment, has a lot of replicated data."
- "I would like to see an improvement in the handling of large amounts of rights."
What is our primary use case?
Our primary use case of this solution is deduplication.
What is most valuable?
The feature I find most valuable is the deduplication because the nature of the data that we are using in our current environment has a lot of replicated data. You tend to create a copy of the same system multiple times for different reasons. So if you use a flash system that is deduplication-enabled, you end up using less capacity.
What needs improvement?
I would like to see an improvement in the handling of large amounts of rights. An automatic flash system that doesn't do compression or deduplication will flush through the rights directly from the host to the flash modules. It doesn't keep them in the cache. For compression and deduplication systems, they have to do compression, deduplication and the memory and cache for the controller. So they have to keep the data there otherwise you will find yourself stuck with performance issues.
For how long have I used the solution?
I've been using the solution for four years now.
What do I think about the stability of the solution?
The solution is currently hosting our core banking system and we haven't faced any stability issues, so it is very stable.
What do I think about the scalability of the solution?
I have only four boxes now, so it's not the best scalability you can get, but it is still acceptable. Since we are hosting our core banking on it, we have about 20,000 employees working on it.
How are customer service and technical support?
I will rate their technical support an eight out of ten. If you send them a question, it takes them ten days to come back to you with an answer. But besides this, we've had no other issues.
Which solution did I use previously and why did I switch?
We use EMC devices and IBM FlashSystem concurrently, but we have a different evaluation for these products. They are not the same because our critical applications are hosted on IBM FlashSystem. The less critical applications are hosted on VMAX.
How was the initial setup?
The setup of the IBM devices is really straightforward. The actual deployment for the IBM FlashSystem took about seven hours. One of our partners was responsible for this, and we are very satisfied with his performance.
What other advice do I have?
My advice to others would be to go for the big one, the A9000. It is a little bit more expensive but it offers a better total cost of ownership.
In the next version, I would like to see external virtualization. We are currently using LVC for external virtualization, and then we are using the boxes under LVC. If IBM embeds the LVC feature inside the box, I will only need to use the box and then virtualize the smaller boxes behind it. It will simplify my issues.
I rate this solution a nine out of ten.

Easy to use and configure
Pros and Cons
- "One of the most valuable features is that it's very easy to use and configure. It used to be more difficult, but now it's almost flawless."
- "The pricing could be improved, but I think it's getting better and better with each version. IBM needs to implement NAS storage again, as this is a big flaw. Dell EMC is very good at this and if you compared them based on NAS storage, Dell EMC would win right away. IBM's solution for NAS storage is very complicated. We don't have a storage box that provides file sharing from itself, we have to put software on it and go through a whole complicated process. It should be simplified."
What is our primary use case?
The general use cases depend on the size of a company. I work with the commercial sector, the FlashSystem 5000 and its different models. It suits the small to medium, or SME, companies. The FlashSystem 9200 goes mainly to big enterprises, like banking or governmental sectors. The 7200 plays sometimes in SME and sometimes in bigger enterprises.
What is most valuable?
One of the most valuable features is that it's very easy to use and configure. It used to be more difficult, but now it's almost flawless.
What needs improvement?
The pricing could be improved, but I think it's getting better and better with each version.

IBM's solution for NAS storage is very complicated. We don't have a storage box that provides file sharing from itself, we have to put software on it and go through a whole complicated process. It should be simplified.
For how long have I used the solution?
I have been working with IBM FlashSystem for around seven years.
What do I think about the stability of the solution?
It's really stable, and many customers have experienced this as well.
What do I think about the scalability of the solution?
It's easy to scale, but it depends on the model. The 5100 is obsolete, but the 5200 has line expansions, up to two controllers, and can scale out both ways. The 7000 and 9000 can scale to 20 expansions and four controllers. It's very scalable, both horizontal and vertical.
How are customer service and support?
I believe the second line and third line are very responsive here. It depends on the customer's warranty level, if it's 9x5—it can't be like 24x7, which is immediately.
Which solution did I use previously and why did I switch?
IBM has some features that don't exist in other brands. External virtualization, for example—Dell EMC has the same feature, but it's applied differently. IBM's approach is to make it usable in many different scenarios so that the customer can work with multiple vendors under the IBM controller. Dell EMC can't do that. The external virtualization stacks with Dell EMC, and the features stack to every box. If I have a main box with high specs and I virtualize another box with minimum specs, that means I'm stuck with the minimum specs. With IBM, if I'm working with the virtualization engine with higher specs, I get the benefits from these higher specs, even if the virtualized box has minimum specs.
How was the initial setup?
The initial setup is very straightforward and user-friendly. The FlashSystem 5000 can be deployed in around 20 to 30 minutes, but it depends on the number of volumes and the tools we set up afterward. On average, it can be installed and initiated within an hour, including microcode updating. If you calculate from the time I begin unpacking to the time I start to configure volumes, it will not exceed around 45 minutes.
What about the implementation team?
I implemented myself.
What's my experience with pricing, setup cost, and licensing?
The pricing may be a bit higher than other brands. If you compare the IBM FlashSystems in midrange with Dell EMC in midrange, IBM costs a bit more, but I prefer IBM because it has more specs that I can benefit from.
Two years ago, we had all features installed in the midrange box without any need for extra licensing. However, lately we have features like Easy Tier and FlashCopy, which need extra licensing. We can purchase it with the box or afterward, and it's a smooth process.
What other advice do I have?
In my experience, IBM doesn't need maintenance at all. Every year, there is a microcode update to get a new feature or fix a bug, but I know some customers who have had the box for more than five or six years without updating it and it still runs well.
To anyone who's looking into implementing IBM FlashSystem, I would advise you to read the instructions on the box. If you follow the instructions, implementation will be very smooth and easy, even if you're not a professional.
I would rate this product a ten out of ten.

Senior Systems Consultant at a tech services company
One screen to control multiple arrays means simplified administration
Pros and Cons
- "Ability to manage third-party arrays and virtualise them: One screen to control multiple arrays. Simplified administration."
- "One area for improvement is in the GUI, where host clusters are not properly dealt with. With Hypervisor host clusters, all hosts must see the same volumes in the same order. Using the concept of a “host-group” has been around (even with IBM) for many years, so why not with the V7000?"
What is most valuable?
Storage virtualisation: Use o storage pool to spread I-O load across as many disks as possible, reduces “hot spots”.
Ability to manage third-party arrays and virtualise them: One screen to control multiple arrays. Simplified administration.
Auto-tiering with Easy-Tier: High usage volumes and parts of volumes are automatically moved to high performance disks in manageable “chunks”. This means volumes with heavy I-O usage are are moved to SSD for the best response. Zero admin overhead.
How has it helped my organization?
Using V7000, the storage administrator has complete visibility into the I-O load and response times of the volumes, storage pool. Together with “Easy Tier”, this means volumes with high workloads are automatically moved to the highest performing disks (SSD) in the array. There is almost zero administration required once the storage pool is established.
Data migration: The migration wizard made migration from old to new an absolute doddle. Something that historically had been “hard and difficult” became a background task, once the old array was managed by the V7000.
What needs improvement?
The replication of data between IBM Storwize arrays in V1 of the product had some major limitations. A lot of the limitations were overcome in V2 of the product. Some improvement can still be made in scalability using clustered V7000 nodes.
One area for improvement is in the GUI, where host clusters are not properly dealt with. With Hypervisor host clusters, all hosts must see the same volumes in the same order. Using the concept of a “host-group” has been around (even with IBM) for many years, so why not with the V7000?
For how long have I used the solution?
Four years.
What do I think about the stability of the solution?
Some isues were encountered during upgrades in the early firmware versions. This has now been resolved.
What do I think about the scalability of the solution?
The V7000 can scale up to 10 enclosures (disk shelves), each up to 24 disks per enclosure. A cluster of 2 x V7000 has twice the capacity.
Using the V7000 you must be careful not to overload the CPU and disk backplane. When planning to implement any storage array, you must plan your workload carefully. IBM have a superb tool, Disk Magic, that predicts the I-O performance of the array configuration you have selected. This is an invaluable tool in planning any IBM storage array.
How are customer service and technical support?
I was lucky to have a very good relationship with the local IBM storage support experts. The implementations were done under IBM guidance and, knowing this, any issues that came up at my sites were quickly dealt with. The support staff knew the arrays had been installed with expert guidance and had no inherent issues in design.
Which solution did I use previously and why did I switch?
Previous storage solutions included the HPE 3PAR array family. We switched to IBM for 3 reasons:
- Upgrade cost
- Complexity with administration tasks and day-to-day running
- Support costs
How was the initial setup?
The IBM V7000 initial setup was straightforward, as I had engaged IBM support early on and was given very good advice on how to size, configure and implement the array(s), including data migration from the old to the new.
What's my experience with pricing, setup cost, and licensing?
It pays to go back and get the best price you can from your supplier. The first offer is not always at the best discount.
Ensure that all the features you need (including replication) are included in the license options.
Which other solutions did I evaluate?
Several vendors were evaluated in addition to IBM: HPE, NetApp, EMC.
What other advice do I have?
- Download the IBM Redbook on best practices to implement.
- Engage IBM support or your integration partner/reseller at a detailed level.
- Know what you want to do and document your requirements.
- Investigate upgrade costs and five-year maintenance options.
