Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."Cost, racial per terabyte, and speed is why we chose PureStorage. It was no brainer."
"The predictive performance analytics is a very good feature, as our system is performing better than before."
"There was a dramatic improvement in operating costs just as a result of the environmentals and space, let alone the cost of the unit itself."
"The speed is the most valuable feature of this solution."
"The first set up we had was really straight forward and simple."
"It allows engineers to focus on other things rather than doing the more manual tasks. It automates tasks, so the ease of use is extreme. It simplifies the storage."
"NVMe data storage platform that's easy to set up and easy to use. It's stable, with a lower response time, and quick technical support."
"Data deduplication is one feature I found to be the most valuable in the tool...Stability-wise, I rate the solution a ten out of ten."
"Built-in snapshot support gives us SAN-side functionality most other platforms would have had us license separately."
"The most valuable aspect is the use of solid-state storage drives instead of spinning drives."
"Inline compression"
"The increased performance is many times above our previous array performance in all metrics. Integration with vSphere features is also a definite plus."
"The capacity that we're saving by using Kaminario's K2 is giving us a four-to-one ratio for our deduplication."
"The ratio between the physical storage and the storage we use is very high."
"The most valuable feature is definitely the always-on data deduplication."
"Latency is definitely the big key for us."
"This product has very good performance when it comes to virtualization storage and works well with solutions such as SAP HANA, Exadata, Hadoop, and Big Data Analytics."
"I have found that the multi-homing feature is very valuable in VMware vSAN. It is an easy-to-use solution."
"We are finding that vSAN is a lot more scalable and adaptable, because we can go in with hybrid arrays for our lower-end storage needs or with all-flash versions of vSAN for places where we need more performance, and it's coming in at a lower cost point than an actual traditional array."
"Being able to deploy multiple applications with virtual servers is the most valuable for us. The capacity of the system is quite constant so it's got some of the good features."
"Being hyperconverged, it simplifies what equipment we have to buy."
"It's very scalable. I like that. Adding a node is easy. Adding a disk group is easy."
"When we do to do more scaled load testing, we can run more dense workloads and still have the same results across all specific nodes"
"The valuable features of vSAN are that you can get it up and running quickly, you get redundancy built-in, and it's pretty much the perfect solution for a cluster."
"The technical support is okay, but could be improved."
"I would like a feature to integrate with external or cloud solutions. For example, if I want to use this storage for a backup from the cloud, I want to have integration with the cloud vendors, such as Microsoft, Oracles, or Amazon. It could be available as an API to allow seamless integration. Additionally, the solution could improve by having native integration with a cloud provider, such as VMware or Microsoft, this would reduce the need to use third-party solutions to complete the task."
"They are doing some stuff with containers and an object search. These could be improved, because containers is one of the main topics that we are talking with our customers about."
"We would like to see better troubleshooting aspects. It helps us if we can find out where the problem is. Right now, it's difficult. Sometimes it's difficult to pinpoint the issue. If they had more visibility and more troubleshooting feature built into the tool that would really help."
"Pure Storage FlashArray could improve some aspects. There are certain features that are good and there are some features that I see some issues with at the technical level. Those issues are related to replication. They need to resolve those issues, which I have already highlighted to the Pure team. Additionally, there are some issues in the active cluster that could improve."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"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."
"I would love for them to have a hyper-converged solution."
"I would like to see them work with Cisco, so it comes off the FIs, instead of having to go through my 10-gig network."
"Access to technical support should be improved for our region. Technical support is good, but they're very hard to access."
"Some of the nice to haves for us, in terms of today, would be VVols but again, it’s not a critical feature."
"I would like to see LDAP for the management panel; I've been notified they might be currently working on it."
"The system currently has a 15TB LUN size limit and that snapshots need to be scheduled through script API instead of the GUI."
"Improved scale and budget planning with flexibility of the solution for budget needs and efficiency for growth with the great optimization ratio due to the nature of our use."
"I'm hoping to see Active Directory integration. Right now, you still have to use a local admin account to log in and manage everything."
"I think it should have better performance with small files. With big data, its performance is top notch, but it is difficult to load small files."
"A vSAN cluster must have compression and deduplication to be an all-flash array, but it's not supported with a hybrid array. Deduplication and compression work better with an all-flash array, so I think that VMware should give customers the option to activate and support this feature for hybrid arrays. Other products like Nutanix support this."
"The only negative point relates to the licensing. If you want multiple, different servers, it costs money, but you have all the capacity for vSAN. You do not reach the data, but the processor arrays and the current architecture."
"In a future release, they could add micro-segmentation or security level features integrated into vSAN."
"Because of virtual storage, the system reaches reserve storage for its functions. It also consumes a certain amount of storage, which then results in the creation of a fault tolerance for the system. All of this adds to a lot of capacity being consumed in terms of storage for each drive for vSan. I find this to be one drawback of using vSan."
"The only thing I can think of at this time is to improve the performance monitoring and performance visibility within the GUI."
"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."
"The monitoring feature in VMware vSAN could be better."
"The server files are larger than before."
