We performed a comparison between DDN IntelliFlash and VMware vSAN based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Hitachi Vantara and others in NVMe All-Flash Storage Arrays."We like the data reduction rates. That has been really helpful. You get 4U of Pure storage replacing something like two racks of spinning disks. One of the things that has contributed to that are the data reduction rates."
"Pure is simple to set up and manage on a day-to-day basis."
"Most of the problems that we had in the past with the performance in IOPS have disappeared. It has been a great improvement for our customers' services."
"The performance of the storage is just unbelievable."
"The console is simple to use. It has good performance. It is easy to install, understand, and manage, with a good ratio of deduplication and compression. It is doing its job."
"It's just very easy for general block storage."
"It simplifies building out the storage."
"Before we used Pure Storage it took 93 days of employees who run the database to back up and restore databases. The scale of deployment basically went from several days to a few minutes."
"High performance and ease-of-management are the most valuable features."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"It performed great originally, and when it performed great, it was awesome."
"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."
"The initial setup is straightforward."
"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."
"The most valuable features are its price point and that you can use existing storage; no specific storage requirements are needed."
"It is easy to find information out there, not only from searching the web, but even the times I have engaged VMware support."
"Technical support is good."
"If we decide to expand, vSAN could offer us some flexibility. We are researching ways to set this up from a new data center, which is located somewhere different from the current location right now."
"The solutions best feature is that it is easy to use."
"Overall the solution is very good."
"Flexibility, growth, and expansion are probably the more important features for us. As our environment grows, the more users come on, the more VDI workstations that we need, we can easily expand either horizontally or vertically with the environment"
"It is very easy to set up and very easy to use. It is very useful."
"I think replication is one area that still needs improvement. Earlier, Pure Storage FlashArray only had IP-based replication. There was no API-based replication, but they have enhanced the feature now. However, they need to work on API replication for C-type of arrays."
"As long as they always improve on IOPS speed, that's all we're really looking for. The faster the storage can be the more we can do speed of application and speed of use."
"There's always an opportunity for new feature functionality."
"What it needs to do is work a little closer with solutions, like VMware, so it understands the particular workloads that are on it. Today, it does not understand the applications which are running against it."
"Most of our upgrades have not been as smooth as they should have been."
"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 backend of this solution utilizes an Active/Passive architecture, rather than an Active/Active architecture, which is a disadvantage, when compared to some of its competitors. Its storage capacity should be expanded in the next release."
"As partners, we should have the option to download the software, rather than have to go back through Pure to obtain it."
"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."
"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."
"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."
"The platform’s pricing needs improvement. Additionally, there should be an appliance module included in it."
"Improvements can be made with respect to scalability."
"We would really like them to look at what Nutanix did for day-one/day-two operations deployment: Bringing in the equipment, getting it deployed, getting it setup, and ease of use of one-click for deploying our 30-node solution. With vSAN we had to go into each one individually and set it up."
"There could be more features with the automatic backup."
"vSAN does not have online dedup. When opening the inline dedupe, the performance will be lower than off inline."
"Disaster recovery needs to be improved, when there is a crisis, there is a problem with what is the quickest way to get out of it."
"Lacks an integrated backup solution."
"I am looking for more of a software-defined storage platform that uses different protocols, such as iSCSI, NFS, and CIS, and maybe also has an object as part of that. They should 100% make it more of a storage-based product where it is not linked just to VMware, and it also has NFS and iSCSI built-in at a scalable level. They should turn it more into a dedicated storage-as-a-service platform instead of just being built into the VMware kernel. Their level one and level two support is not at all good, and it should be improved."
