Room For Improvement

IBM FlashSystem requires enhancements in scalability, integration, user interface, and support, with better deduplication, monitoring, and streamlined processes.
Qumulo should minimize upgrade downtime, enhance control, refine pricing, support protocols, and improve interfaces and hybrid cloud mobility.
Despite marketing promises, these features do not function effectively and can impact performance.

Setup Cost

IBM FlashSystem offers competitive pricing, but evaluating long-term needs and negotiating discounts is crucial to manage costs effectively.
Qumulo offers moderately priced, easy-to-understand licensing and setup, with some viewing costs as premium in specific industries.
To install or upgrade any software features, the cost is high, which makes it challenging for smaller companies who do not require advanced features like deduplication or compression typically needed by larger organizations.

Featured Reviews

OmarIsmail1 - PeerSpot reviewer
Infrastructure Technical Specialist II at Clicks Group
Offers high performance and dependable support for fast storage needs
The most valuable feature of IBM FlashSystem is its robust back code. When integrated properly into the environment and configured according to the guidelines, it provides a very solid infrastructure that does the job on demand. Additionally, IBM FlashSystem offers competitive pricing and reliable performance. The hardware is dependable, ensuring that it functions effectively when the setup is done correctly.
Esther Sultaana - PeerSpot reviewer
Storage Consultant Storage at Hewlett Packard Enterprise
Unified file platform has delivered secure multi‑protocol access for massive data growth
The creators of Qumulo were the ones who created Isilon, and I had a conversation with them, so any of the features within Isilon may need tweaking, but I think they resolved it here. In the year that I worked with it, I did not see anything that I had an issue with. The security is great, and it works with cloud technologies, being a hands-based tool, so you can use it with AWS or Microsoft Azure. It programs very easily. There are REST APIs, and there is a cloud connection. The management and program layer is made up of three capabilities: API, the command line, and a visual interface. In the year that I worked with it and brought it in, I think it has been effective. The only thing I would like to see added to Qumulo is for the interface to improve visually, more in line with vCenter, but that is just my thought. Overall, I appreciate it.
