Pros & Cons summary

IBM FlashSystem supports high IOPS rates with low latency, making it ideal for demanding applications. It includes performance features like compression, deduplication, and virtualization for enhanced data management and easy third-party array management. While setup is efficient and reliability is high, data replication and scalability options need improvement. The absence of Amazon File System S3 protocol and limited access to firmware patches are noted limitations. Enhancements in storage capacity and data reduction are needed for optimal performance.

They have a virtualization feature and, even if you do not want to buy that feature, you can have it as a trial for two to three months. If you have another brand of storage from another company, you can use this tool to transfer all your data from the old system to the new Storwize system, which really shortens the migration time.

I have looked at a few pages of a report I download and I saw a graph there regarding software-defined vendors. IBM is not in a good position on this graph. I know that they are working very hard on this, to make it much better and to get to a level where it's not only hardware but also software to provide a complete solution.

This product lacks some of the options we wanted. For example, expansion was difficult and it required a lot of patching to be done.

They can include Amazon file system S3 protocol in the upcoming releases. It is a cloud file system. IBM FlashSystem doesn't have this feature in the box for high-end or mid-range. We have got requests for this from customers because we need to use S3 for EDI application storage. At the beginning of every year, IBM releases firmware. When I find any bugs in the firmware during the year, I am unable to find any information from IBM regarding the bug. I need to open a ticket, and the IBM engineering team makes a patch only for me. This patch is not public. By creating a customized patch for a client, they don't really solve the issue for everyone. If multiple users have the same bug, IBM should upload the patch on the official website so that we can download it. IBM FlashSystem has a monitoring tool in the box, but it is not advanced. I need a more advanced tool for more advanced equations and monitoring. All top three storage vendors, that is, EMC, IBM, and Pure Storage, don't have a powerful monitoring tool. To monitor our box to show the statistics for I/Os and latency, I need to pay for extra software. The built-in monitoring storage is not mature enough to handle all requests and generate all reports that I need. They can include the functionality to stretch a cluster natively without using any additional boxes. In addition, there are some features that EMC has integrated with the box. These features are not available in IBM FlashSystem.

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.

They can improve its initial configuration. The initial configuration is currently very difficult. There are multiple choices or alternative ways to configure based on the use case and what you are targeting out of the device, that is, more capacity or more performance. These multiple alternatives cause a lot of confusion. They should increase the processing part of the nodes. Currently, you can cluster up to eight nodes. From my experience and the workload that I am facing in my environment currently, I would like to see either a bigger or stronger node or a larger number of nodes that can be clustered together. We formally communicated to them that we need to see either this or that, and they are working on something.
