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)."The solution has probably reduced my power use substantially."
"Has also helped simplify storage for us. The other person we put in there, took about a week to implement. And we had both arrays set up within around four hours with a thirty minute drive time between the two locations."
"I like the speed, and I like the API and how programmable it is."
"It has made working with storage as easy and simple as it should be."
"The most valuable features are extremely low latency, high IOPS with VMware, inline deduplication and compression."
"It comes with a large number of features out-of-the-box, which makes it easy for us to see problems and manage capacity."
"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."
"It is easy to manage. You don't have to have the same people who used to manage the Dell EMC arrays because the solution is more intuitive."
"The performance of the All-Flash System is very good. There is more enhanced performance and data production in the solution, which I appreciate."
"IBM FlashSystem is flexible, quick, and has a solid design."
"The maintenance service and support from IBM is very good."
"The solution is scalable and has varying degrees of scalability."
"The FlashSystem 900 consistently delivers performance below 1ms for read/write. This performance is essential for an effective SVC stretch-cluster configuration across two datacenters, and presenting active-active storage to the customer."
"Virtualization of external storage, while adding cache and speed to the external storage."
"The initial setup was really straightforward. It was not complex. Deployment took one month, due to the data migration duration."
"IBM FlashSystem has an easy to use GUI, similar to the IBM Storewize family, which make it one of the best flash storage systems in the market."
"Integration with VMware"
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
"I really value deduplication and compression to save space."
"It is very stable, even during multiple power failures."
"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."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"We have not seen a reduction in our TCO nor have we seen ROI."
"I would like some form of QoS implemented. As a service provider, it would be beneficial to have it."
"Pure Storage support could be a little better."
"It needs to improve its price."
"Its price could be cheaper. It is not the cheapest one out there, but I'm not directly involved in the figures and negotiations."
"We would like to see more cloud support, which we know is coming, although it's not out yet. It's going to be released in the next versions. That would be the biggest win, if additional cloud support is built into the array."
"I would rate this solution an eight. There's always room for improvement, nobody is perfect to get a ten out of ten. They do what they do well. It's not cheap but we it's for uses that we needed."
"I would love for them to have a hyper-converged solution."
"Their technical support needs improvement in terms of reachability for the clients and response times. They should be more responsive and have more online platforms for support. They should make more technical information available online. There could be some kind of documentation community."
"Customization features must be improved."
"It could be easier to implement."
"IBM should improve its data reduction development."
"The Data Reduction Pools (DRP) support could be better."
"The only issue my team faced was transferring the data from the old system to IBM FlashSystem, which is an area for improvement in the solution."
"The solution is quite expensive. That's one of the downsides to using it."
"Our model does not support compression or deduplication."
"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."
"Poor connection to FC."
"There is no easy way to defrag a RAID group. It would be nice to be able to reduce the size of a storage pool if the storage is not needed anymore."
"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."
"Based on our workloads, we see repeatedly in performance reports that the built-in controller (SP) cache of our VNX model is not sufficiently large, resulting in forced cache flushing."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
