IBM FlashSystem Review

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.

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.
