We performed a comparison between IBM FlashSystem and VNX [EOL] based on real PeerSpot user reviews.
Find out what your peers are saying about NetApp, IBM, Hewlett Packard Enterprise and others in Modular SAN (Storage Area Network)."Lone segmentation is simpler and more agile. It's improved the velocity in overall provisioning from project to operation."
"It upgrades in place which means we'll be using it well into the future."
"The initial setup is very straightforward. You simply plug it in and turn it on."
"It is easy to deploy and it's all-flash, so it's very fast."
"The mobile app is very helpful."
"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."
"We're getting good performance, and the compression ratio is also very good in Pure Storage FlashArray."
"The job of support for the storage engineers dramatically changed. We know more quickly the automation of the provisioning. We can now focus on things that bring more value to the company than just managing storage."
"IBM FlashSystem is a powerful effective storage solution. Additionally, it is user-friendly, anyone can use it."
"The performance of the All-Flash System is very good. There is more enhanced performance and data production in the solution, which I appreciate."
"The most valuable features of IBM FlashSystem are performance and security."
"High availability and enhanced security; Proven dependability; Data compression with hardware acceleration; Advanced copy services features are all in this product."
"The solution is very easy to configure and use."
"Virtualization of external storage, while adding cache and speed to the external storage."
"The most valuable features were the performance of the array, i.e., very low latency and high IOPS. Plus, the management interface is very easy to use."
"The solution allows for easy migrations from previous products or vendors via its embedded storage virtualization function."
"The replication feature provides another functionality to protect your data."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"The most valuable feature is the tight VMware integration, due to the migration from bare metal to virtualized environments and then on to the cloud."
"From my point of view, the configuration that I can sell is restricted to the EMC best practices. It is hard to make a mistake in a solution. It means the configuration has good performance and scalability options."
"Good performance for VM environments"
"It is very stable even during multiple power failures."
"It is very stable, even during multiple power failures."
"I really value deduplication and compression to save space."
"The way Pure Storage does the controller storage warranty or replacement has been an issue for some people who just replace the controllers every couple of years, and that's where some of the confusion with pricing and support has come in. They should be clear on the way the controller replacements happen, as it is important to know whether or not you can get a good return on them, because it can be a little confusing."
"The data reduction that we had initially anticipated when we bought Pure and we move over, is way lower than the expected reduction. It depends on the workloads, of course. But that has been a challenge at times."
"It's not so scalable. It's got moderate scaling capabilities right now. The clustering technology needs a bit of work, they need to improve that."
"We haven't seen ROI yet."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"Most of our upgrades have not been as smooth as they should have been."
"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."
"We do have an issue with the vCenter integration. Pure Storage says it has a lot of free space, but vCenter says its completely full. This is because their dedupes are saved as space, but Vcenter still detects the disk as completely full. So, we do have an issue with that."
"It is slightly more expensive, however, it all depends on your supplier."
"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."
"It could be easier to implement."
"Additional licenses might be added for the fundamental licenses, such as those for copying and flash copies."
"This solution needs a management console where we are alerted to issues and can report them, or escalate them through email or another method."
"I would like to see an improvement in the handling of large amounts of rights."
"The customer's expectations are what they get on the cloud, they're expecting even in the on-premises deployments, going forward."
"The interface could improve in IBM FlashSystem."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do this."
"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"It would be very helpful to get an automated report that shows you the size of the checkpoints and get warnings when a checkpoint is reaching either maximum capacity per a file system or hitting the ceiling on the SavVol pool consumption."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
"VNX can improve by offering flexible upgrade options. It's not possible to add a single HDD to a current array and there are fixed rules to make upgrades."
"Poor connection to FC."
"There is an easy replication process between distinct data centers via VPLEX and/or RPA. But I hope in the future that EMC/Dell could replicate this with other types of storage."
