The easy GUI is the most valuable feature.
What is most valuable?
What needs improvement?
As I said When you Sync V7000 to Another V7000 that are located in my case more than 10km and with DWDM as dark fiber , first you need license for long distance from brocade.
Than you can change the buffer credit on the SAN switch to at least 49 . the point is that you need to test the parameter to get the best value .
This depend on the line you have and also check if there is any limitation from your DWDM Provider.
The problem is that if the buffer is not configured correctly this increase the latency because of this delay and the retransmit .
For how long have I used the solution?
I have been using it for four years.
What was my experience with deployment of the solution?
Remote copy performance impacts latency on the local storage: Must be configured with the correct buffer credit.

It has helped us to achieve a good response time for users. The memory card failure and the array's inability to create a spare card resulted in several crashes.
Pros and Cons
- "The most valuable features were the performance of the array, i.e., very low latency and high IOPS. Plus, the management interface is very easy to use."
- "The array level RAID does not seem available."
How has it helped my organization?
It has helped us to achieve a good response time for users.
What is most valuable?
The latency and speed of the array and also its ease of management were beneficial features.
The most valuable features were the performance of the array, i.e., very low latency and high IOPS. Plus, the management interface is very easy to use.
What needs improvement?
The several major crashes resulted in the entire weekends being lost in rebuilding the array and then for restoring the data. This was caused each time by a memory card failure and the array's inability to use a spare card. The array level RAID does not seem available.
How are customer service and technical support?
It was great with TMS, however it has been terrible ever since IBM took over.
On one occasion our support renewal had not been processed, which we found out when we tried to get support during an array failure.
Which solution did I use previously and why did I switch?
Previously, it was a great experience with RamSan-400.
How was the initial setup?
The setup is very easy.
What about the implementation team?
We implemented it in-house. It is very straightforward.
What was our ROI?
Since the takeover by IBM, the prices are much higher.
What other advice do I have?
For resilience, you need to buy two of these devices per site as RAID only applies within in each memory card, i.e., the whole array is not resilient if a card fails. Failover would only be possible for a standby device.

It facilitates those applications that need low latency and high speed for transferring the data.
Pros and Cons
- "Speed (IOPS/second) – It is most vital for applications that need low latency and high speed for transferring the data."
How has it helped my organization?
The interface management is simple and intuitive. It has been replaced with other arrays successfully, that were larger in size but more slow. We were able to reduce the footprint of space used in GDCS and also the power consumption.
What is most valuable?
Speed (IOPS/second) – It is most vital for applications that need low latency and high speed for transferring the data.
We have some large databases that are accessed at the same time by more than 10,000 users. In the past, it was on 15K disks. After we migrated them under the IBM Flash Array, the overall IOPS rate has increased by 30% and its latency is lower. The customers are very happy with the new solution.
What needs improvement?
The storage size vs the storage price needs to improve. The total storage capacity vs price is still quite high for the IBM Flash Array. It will sound better in the following years, as and when the price will be more accessible/economical.
Which solution did I use previously and why did I switch?
In our environment we also have the XtremIO All-Flash Storage Array, but it has some scalability issues. That was the main reason why we focused on buying more IBM Flash Arrays.
We also use ServiceNow and SNIA Protocol; it’s present and working good with all the IBM products.
How was the initial setup?
Since we have multiple IBM equipment in use, the installation process was straight forward.
What about the implementation team?
Usually IBM doesn't sell the product directly, so each installation is carried out either with the vendor or via the GDC technicians. We as storage admins configure the storage system.
What other advice do I have?
This product has the best quality, performance and cost.

It supports a high IOPS rate. Initial setup is simple.
Pros and Cons
- "The most valuable feature is that is supports a high IOPS rate."
- "It has room for improvement in the area of stability."
How has it helped my organization?
We have some processes in our company that were cut in half by using the FlashSystem.
What is most valuable?
The most valuable feature is that is supports a high IOPS rate. We have a heavy workload. Some storage systems are not as good in terms of IOPS. We are using just the FlashSystems. It is virtualized using SVCs. We are using normal physical disks like Storwize for not-so-hot data. For hot data, we are using FlashSystems.
I think the performance of most of the application is improving. Our users now say that it's much better than it was before. The storage speed is perfect.
What needs improvement?
It has room for improvement in the area of stability. The firmware is upgraded frequently. We need to update it maybe three or four time a year because of the new features and bug fixes. On one side, it is good; but, on the other side, it is not good because we need to upgrade within one year or they will not support the firmware. It would be better if they supported what we already have for longer.
What do I think about the stability of the solution?
We sometimes had a problem with some bugs in FlashSystems. One time, one FlashSystem was burnt up. There was some smoke and the data was damaged. We saved it because we have redundancy in the cluster. At the cluster level, we make copies and replicate to the other site for disaster recovery situations.
What do I think about the scalability of the solution?
We upgraded one FlashSystem two months ago because it was not full. We had to buy two modules, if I remember correctly. This was quite a complicated upgrade. IBM brought us new FlashSystems. Because it is virtualized, we moved the data from this one, upgraded it, and moved the data back; but it was done dynamically without any outage.
With the virtualized FlashSystem, we hope for improved response time, but the availability is improved. It is also flexible in that we could upgrade it dynamically, move the data, and so on.
How are customer service and technical support?
I think the guys in our country are very clever in this. We can count on them. When we call them, they respond very fast and bring the new parts on time. The repair time is written into the SLA. Support is available 24/7 and I think the repair time is within 24 hours.
Which solution did I use previously and why did I switch?
Before we were using IBM DS8000s. The application was consuming a lot of IOPS with a lot of hot data.
We needed a higher IOPS rate. We chose the FlashSystem because the response time needs to be very fast. When the people working on the application feel that the response time is not good, or there is not enough storage space for the amount of data they have, then we have a flexible enough infrastructure to dynamically upgrade them to the FlashSystem. We do this planning on a yearly basis. We design the infrastructure solution according to the project requirements. Sometimes, this requires an upgrade to the FlashSystem.
How was the initial setup?
The initial setup we did ourselves because it is very simple. We did the direct mounting of racks and the hardware. The software design is virtualized using SVCs.
Which other solutions did I evaluate?
We considered other options, but I don’t think there were any other options with such intensive processing as the FlashSystem. We have a lot of tiers; and for other tiers, we have other vendors. I think that the IBM FlashSystem is the highest quality available in the market. For us, considering the whole solution, it was best for us.
We are very satisfied with IBM's prices, I think.
What other advice do I have?
I would advise colleagues to use FlashSystems. It's a very good solution for us to achieve our goals.
When I evaluate vendors, for me, the historical relationship is very important, and definitely the communication. With IBM, we know the vendor well.

The GUI is easy to use. The SAN Volume Controller provides a single management interface for virtualized storage.
Pros and Cons
- "IBM FlashSystem has an easy to use GUI, similar to the IBM Storewize family, which make it one of the best flash storage systems in the market."
How has it helped my organization?
We used to provision storage from different devices. This requires a lot of manual effort to synchronize all hosts with each storage unit in an environment. IBM SAN Volume Controller helps manage all storage units from a single interface; while IBM FlashSystem provides high performance for our Tier 1 applications.
What is most valuable?
IBM FlashSystem has an easy to use GUI, similar to the IBM Storewize family, which make it one of the best flash storage systems in the market.
We use the IBM SAN Volume Controller to provide a single management interface for virtualized storage. It is easy to manage many storage devices from a single controller.
What needs improvement?
The two products should be unified and have a service processor to restart devices remotely. For example, NetApp has devices which include a service processor in nodes, which could be used to restart the nodes remotely. IBM should implement something like this.
Both products are basically for block-level access. There should be a series that also has a file level and block-level access together, which would make it unified.
What do I think about the stability of the solution?
The stability of the system is fine.
What do I think about the scalability of the solution?
We did not have any problems with scalability.
How are customer service and technical support?
We receive excellent technical support.
Which solution did I use previously and why did I switch?
I currently use both NetApp and IBM. NetApp storage is cost efficient, but IBM is way ahead of NetApp in terms of block-level access.
How was the initial setup?
The initial setup was easy.
What's my experience with pricing, setup cost, and licensing?
Pricing can be considered as per market competition. As I am seeing less projects using IBM storage these days, the only reason seems to be the cost of support.
Which other solutions did I evaluate?
We had a contract with IBM, and now we are also using NetApp storage.
What other advice do I have?
Go ahead and implement it. IBM storage provides you everything that you’ll need for a block-level architecture, as they have many different products which provides you with a variety of options to meet your needs.

The services to help us migrate our NAS data from an existing EMC VNX system has failed once already with ACL permissions issues specifically on how the V7000U NAS works.
What is most valuable?
We have not had a good experience with this platform.
The installation and service was very good. But, the services to help us migrate our NAS data from an existing EMC VNX system has failed once already with ACL permissions issues specifically on how the V7000U NAS works. I have had to involved IBM Global Support by actually contacting high level Vice Presidents. As of January 26, 2016, we have not successfully migrated our NAS data.
How has it helped my organization?
It has not improved anything yet within our environment.
What needs improvement?
They could increase the maximum storage capacity so more disk shelves can be added.
For how long have I used the solution?
We've had it for eight months, but still have not successfully migrated our NAS data yet. Also, it contains drives for AS/400 system and Exchange Archive data.
What was my experience with deployment of the solution?
Software functionality issues that were not known until our NAS data migration failed. We hit further ACL Permissions issues as well.
What do I think about the stability of the solution?
We have performance and spiking issues of which IBM applied a work-around patch.
What do I think about the scalability of the solution?
There have been no issues with the scalability.
How are customer service and technical support?
Customer Service:
6/10
Technical Support:It's average.
Which solution did I use previously and why did I switch?
We switched to Pure Storage because of the way the system performs and does everything in 32K sizing. The IOPS are high and the support and customer server are exceptional.
How was the initial setup?
Fairly simple as it took about two hours to rack and get on-line.
What about the implementation team?
It was installed through one of our partners who did a good job.
What's my experience with pricing, setup cost, and licensing?
We feel that the pricing is fair and the licensing process was easy.
Which other solutions did I evaluate?
We evaluated EMC (which we already had), DELL and HP.
What other advice do I have?
The sales team was great as was the technical team. I now feel the EMC VNX and NetApp are both better NAS systems. If I had to do it over again, I would stayed with the EMC VNX for NAS.

Micro latency of the flash provides real-time information, but it's a little expensive.
What is most valuable?
The most valuable features of all the products are the high performance and micro latency.
How has it helped my organization?
I'm a Solutions Architect, so I don't have any from my company, but I do some projects for some clients where the unique performance and micro latency of the flash provides real- time information that is used to make strategic decisions.
What needs improvement?
Because the product is already mature, it doesn't need any improvement.
For how long have I used the solution?
From about two years when IBM first bought FlashSystem. I knew some things about it when it was Texas Memory System,
What was my experience with deployment of the solution?
I didn't have issues with models 900 and v9000, but on previous versions, like the 720, I had some questions.
What do I think about the stability of the solution?
It is stable, because it's use an ASIC in it's development. Therefore, that does the job and it doesn't have software at its core.
What do I think about the scalability of the solution?
It has great scalability.
How are customer service and technical support?
Customer Service:
It's very good because IBM always make sure they have good customer service.
Technical Support:Not so good in my country because they only have a few people with great knowledge about FlashSystem.
Which solution did I use previously and why did I switch?
I've never used another solution.
How was the initial setup?
The initial setup was very simple, because IBM have a default interface for all their storage systems.
What about the implementation team?
I did the implementation in-house.
What's my experience with pricing, setup cost, and licensing?
It's a little expensive, so it's you need to have a good architect involved to explain it and make sure the project goes well.
What other advice do I have?
Have good knowledge about the clients business.
