We performed a comparison between Kaminario K2 [EOL] and VNX [EOL] based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."One of the lesser sung advantages was when we started running our interface engine on Pure Storage. The ability to process messages and pass them through in our organization skyrocketed purely because of a disk that I owned which we were getting out of Pure Storage."
"It simplifies the overall management. We don't have to worry about storage anymore."
"The reliability is very good."
"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."
"The code upgrades are very smooth."
"It is the SAN backbone for our company."
"The stability and performance are the best things about the solution."
"Processes that used to take 40 minutes to two hours can be completed in five minutes."
"The increased performance is many times above our previous array performance in all metrics. Integration with vSphere features is also a definite plus."
"Built-in snapshot support gives us SAN-side functionality most other platforms would have had us license separately."
"The GUI is very straightforward and easy to use."
"Ease of use: My installers - my administrators over the system - they love how easy and fast it is to install and spin up a LUN and get going."
"The speed and, for us in particular in what we're doing, the data de-duplication."
"Inline compression"
"It provides a full feature set without separate licensing (deduplication, compression, snapshot, asynchronous replication, stable performance, etc.)."
"Data reduction and snapshot abilities: Smaller footprint in the datacenter (lower cost for power, cooling, etc.)."
"It is very stable, even during multiple power failures."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"I really value deduplication and compression to save space."
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
"One of the best features of the VNX is the ability to combine drives of different types into a virtual Storage Pool. By combining small but fast flash drives, SAS drives, and high-capacity but slower NL-SAS drives, the VNX can intelligently move data to the different tiers of storage based on usage."
"Multi-tiering, positively affects the efficiency of the storage space."
"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."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"Part of our company works on Dell EMC because Pure Storage did not have synchronous applications when we were purchasing our products."
"I would like to see a Nagios monitoring plugin which watches the health and performance of the system. The only one available just checks volume capacity."
"They have a product, FlashBlade, which is their object storage integration, and that's something that we haven't integrated with yet. This might be an area for additional focus as it would play into scalability, because the very nature of object storage is that it's infinitely scalable."
"Having something native in the Pure Storage ecosystem would make it integrated and in one single company, and we wouldn't have to work with multiple organizations."
"The time-to-market could be better at times, but I think that's true for all vendors of hardware."
"I would like the ability to swap out the network adapters into it. So, without taking out the whole controller, I would like to be able to swap adapters. This would make things easier."
"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."
"In the next version of this program, I would like to see increased security, higher encryption, and faster throughput."
"Access to technical support should be improved for our region. Technical support is good, but they're very hard to access."
"I would like them to improve the look of the product’s external casing and shelves."
"Some of the nice to haves for us, in terms of today, would be VVols but again, it’s not a critical feature."
"A single pane of glass to monitor/manage multiple arrays would be helpful."
"The front panel of the drive shelf doesn't always seat firmly."
"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."
"I would love to see capacity on its DRAM. I know it's not cost effective for them to do it, but I think that it could be a big differentiator and was a big differentiator from the beginning."
"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."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
"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."
"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."
"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."
"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."
"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."
"The management software used for the VNX is Unicenter. While it is an improvement over Navicenter, used in older EMC SANs, it still feels outdated in comparison to other SAN management software."
