Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage.
"The performance is very good."
"We've had different types of storage, and three things of this solution are valuable. The first one is its outstanding performance. The second one is its stability. In the about three years that we've had it, we've had component failures, but we never had a service interruption or any data loss. The third one, which is really critical, is that it is super easy to use in terms of provisioning, storage, and managing the arrays. I'm able to maintain a multi-site environment with a couple of dozen arrays with a single mid-level storage admin."
"Simplicity and reliability are the most valuable feature of Pure Storage FlashArray."
"The predictive performance analytics are good."
"It has been very stable. I have not seen or heard of downtime storage issues after moving over to it."
"We've been using FlashArray's snapshot for backups. Their replication across sites and response time are also excellent."
"Having fast storage allows actual servers to perform in high capacity so we don't have slowdowns on our applications."
"The top-tier support and reliable storage are the most valuable features of this solution."
"It performed great originally, and when it performed great, it was awesome."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"Data Compression: Up to 80% space reduction in the database"
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"High performance and ease-of-management are the most valuable features."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"The initial setup is straightforward."
"User friendly management interface."
"The all-flash storage has tier replication capabilities."
"IBM FlashSystem is a flexible solution with plenty of features."
"IBM FlashSystem is flexible, quick, and has a solid design."
"The initial setup was really straightforward. It was not complex. Deployment took one month, due to the data migration duration."
"The initial setup is straightforward and can be done in an hour and a half by one person."
"The performance monitoring feature is useful as it can report in 15 minute intervals by hour, day, week, month, or by a custom date range."
"The most valuable feature of the solution is compression."
"Pure Storage FlashArray could improve in the area of cryptographic information in the consoles. The user-friendliness could improve. The Pure Storage FlashArray team should come and log into the system with their maintenance credentials and then pull out the information as evidence of cryptography."
"Data reduction is an area that needs improvement. There is a garbage collection service that runs but during that time, system utilization increases."
"The price should be lower."
"We would like to integrate it more with our backup solutions."
"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."
"On a couple of occasions, the waiting time for an upgrade has been pretty substantial."
"Pricing could be better in comparison to other solutions."
"I would like to see support for NVMe, end-to-end."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."
"In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."
"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"It's somewhat scalable, but maybe not so much as some of the competition."
"Snapshots are not as easy to access as on a NetApp device."
"The price is very costly."
"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 solution's pricing is a bit high so there is room for improvement."
"It has room for improvement in the area of stability."
"The technical support in my region is satisfactory but it could improve. Support is very important for customers and downtime is very critical for us. We would like onsite or complete technical support which can help us to minimize our downtime or if problems occur."
"The pricing needs to be more competitive."
"The solution should improve its pricing and the mechanism in the reduction pool."
"The solution is quite expensive. That's one of the downsides to using it."
