We performed a comparison between DDN IntelliFlash and Hitachi Virtual Storage Platform based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."The most valuable feature is its speed."
"The most valuable feature is that maintenance is free."
"We find the ease of usability and setup valuable."
"With Pure Storage, we don't see any latency or IOPS. It has been a very seamless integration."
"We were actually able to do multiple upgrades, including head upgrades and moving between the platforms, M20 and M50, over the years. We have never once lost a ping and have never had an outage due to an OS upgrade or a complete head upgrade."
"The solution has probably reduced my power use substantially."
"It is fast and reliable. It works."
"The scalability is good."
"The initial setup is straightforward."
"It performed great originally, and when it performed great, it was awesome."
"Data Compression: Up to 80% space reduction in the database"
"High performance and ease-of-management are the most valuable features."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"The deduplication is useful for us because we don't have that much money for our lab infrastructure. Deduplication means we have more storage available. And the IOPS are really fast."
"The feature I like best is the stability of the hardware."
"In terms of performance and ability, the product can stand up against its competitors since the solution offers two controller systems to users."
"The hybrid array provides scaleable, predictable, high performance with no capacity constraints."
"The first thing that attracted this model to us was the non-disruptive migration. We had a very large database application that was on older gear and needed to be migrated to these arrays. We had experience with virtualizing behind an array and moving applications and data but this made it even better."
"The technical support is great."
"The efficiency ratio is just as high as advertised. It's very high relative to other storage solutions as well. The compression and deduplication capabilities are also very high."
"The product offers high stability."
"There's always an opportunity for new feature functionality."
"As partners, we should have the option to download the software, rather than have to go back through Pure to obtain it."
"If they could make it cheaper, that would be something."
"The support for NFS protocols right out-of-the-box need improvement. I'm used to other storage vendors who have NFS support right out-of-the-box, and Pure Storage doesn't seem to have anything."
"We would like more extended historical data to help with some of the capacity planning. This is something that we are asking for all the time. E.g., what was the historical performance of this particular volume? So, we would like more historicals."
"It would be nice if Pure had something in its portfolio that provided higher deduplication and compression for backups."
"Pure Storage support could be a little better."
"Its price needs improvement. Its price is almost double than any other flash storage solution."
"It's somewhat scalable, but maybe not so much as some of the competition."
"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."
"Snapshots are not as easy to access as on a NetApp device."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"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."
"The embedded management for installation feature has neither simplified nor complicated the management process, therefore, there is room for improvement."
"Hitachi Virtual Storage Platform needs to improve its scalability options where there are a few shortcomings."
"We moved away from this product because we were looking for an all-flash solution, and with our G1500 at the time, perhaps two years ago, they were just proposing more of the same technology."
"There is a drawback related to Hitachi's configuration flexibility. The Hitachi storage platform solution is not flexible. That means that both the Hitachi and the partner presale guys have to do a lot of work to design a solution."
"One improvement I am hoping for in the next release is unified storage."
"The software has always been lagging a bit compared to the newer features. It usually takes a cycle for it to catch up."
"The life-cycle of the Hitachi Virtual Storage Platform G Series is too short. We only had approximately four or five years out of the solution before it was rendered its end of life."
"For the support windows to work, maybe they have to upgrade the firmware of the VSP. They changed the hardware or the disk. I don't know if it was the port blade they changed or a VM for a memory cache. Also, replacing the old target with the processor target would be fine. The old equipment is very easy to manage, and I don't have any bad commentary."
