Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."It is always out of the box, and ready to use."
"Simplicity and reliability are the most valuable feature of Pure Storage FlashArray."
"For us, the most valuable feature is the compression and deduplication. Being able to deploy a three to one ratio for storage is absolutely critical in today's world with the growing need for storage and the growing need for more space."
"The most valuable feature is replication."
"My rating of Pure Storage is a ten out of ten because of the price for performance and footprint - the overall value."
"All updates, upgrades, and hardware work are all performed on-line with no impact."
"It's very fast and very easy to use. It performs well and is both flexible and compatible. We like it because it's easy to use."
"This is the best all-flash storage array on the market."
"The initial setup is straightforward."
"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."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"High performance and ease-of-management are the most valuable features."
"Data Compression: Up to 80% space reduction in the database"
"It performed great originally, and when it performed great, it was awesome."
"This solution helps accelerate demanding enterprise applications. VMware workloads, the database, and Oracle Solaris are hosted on AFF, which means that our primary priority workloads are on AFF and that the secondary ones are on FAS. That includes the SAN national cloud."
"In terms of the footprint, it is far more efficient. It has smaller, higher-capacity drives than our older unit. In terms of space, power, and cooling, it has simplified things."
"Speed. it's very performance designed. It's designed to have a lot of high speed."
"The performance. The flash performance helps move data pretty fast."
"The cloning and snapshot features are the most valuable. With snapshot backup, we can clone a big database in minutes. We take a lot of snapshots for clients in different environments."
"The scale up version of it is the most valuable feature. You can go to 24 nodes, which is very cool."
"The valuable features are the fabric pool. We are taking our cold data and pumping it straight into an estuary bucket. Also, efficiency. We're getting about two and a half times upwards of data efficiency through compaction, compression, deduplication, and it's size. When we refreshed from two or three racks of spinning discs down into 5U of rack space, it not only saved us a whole heap of costs in our data center environment but also it's nice to be green. The power savings alone equated to be about 50 tons of CO2 a year that we no longer emit. It's a big game changer."
"Technical support has been okay."
"The scalability of the solution is not as good as it probably could be."
"Storage. There could be better storage."
"I would like to see data tiering to AWS."
"The problem is that we can only make a few groups, around five or six groups. I like groups and we need a lot of them. We had to put all the information in only a few groups and cannot make a more detailed separation of them."
"The solution is not cheap."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"Pure Storage support could be a little better."
"I would like to have support available in Spanish."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"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."
"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."
"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."
"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."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"In the current atmosphere, private cloud is improving. NetApp AFF needs to provide flexibility in terms of hardware and capital expense."
"When you look at the competitors, they have some features available, for example on the deduplication side."
"Technical support is a little lackluster. Some of the issues that we've had were opening up tickets. They seem to be routed in the wrong direction or it takes one or two days to get a call back for simple tasks."
"There is no direct storage attachment available. Most configurations require additional switches for data access."
"I come tech support with difficulty because I installed NetApp for many years I know what to expect when I call. When I don't get their support tech that I'm expecting and I'm trying to get to the right one, it can get very frustrating for me personally, trying to all-flash push my way into the right person. NetApp has the right people, it's just a matter of getting to them."
"I think for us, improvement would probably be the changes in how the flash is actually used inside the system and how we manage the actual disk and stripes within the system."
"After the three-year prepay, the extended warranty is a little expensive."
"One of the features that I am looking for, which is already in the works, is to be able to take my code and automatically move it to the cloud."
