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."We're getting good performance, and the compression ratio is also very good in Pure Storage FlashArray."
"The solution helps to simplify storage."
"The most valuable feature is test performance. It helps us store large amounts of data along with providing us faster retrieval of data."
"The most valuable feature is its upgradeability."
"We've had to use tech support on a number of occasions. They did everything remotely and talked us all the way through. They fixed the issue within 30 minutes. Every single time we contact them, they're perfect. I would give their technical support a ten out of ten."
"It has been very stable. I have not seen or heard of downtime storage issues after moving over to it."
"The deduplication and compression meet all of our system requirements."
"I like FlashArray's ActiveCluster as well as its snapshot and cloning capabilities."
"Implementation of the solution is very simple."
"Data reduction and snapshot abilities: Smaller footprint in the datacenter (lower cost for power, cooling, etc.)."
"It provides a full feature set without separate licensing (deduplication, compression, snapshot, asynchronous replication, stable performance, etc.)."
"The most valuable feature is definitely the always-on data deduplication."
"The ratio between the physical storage and the storage we use is very high."
"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 most valuable aspect is the use of solid-state storage drives instead of spinning drives."
"The capacity that we're saving by using Kaminario's K2 is giving us a four-to-one ratio for our deduplication."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"The replication feature provides another functionality to protect your data."
"Good performance for VM environments"
"It is very stable even during multiple power failures."
"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."
"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 auto-tiering, which helps in the speed of data access."
"It was a little costly. The price was ultimately higher than both of the other solutions that we evaluated. I'd say that's the only downside."
"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."
"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."
"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 would like to integrate it more with our backup solutions."
"The file functionality could be better."
"I had to contact customer support when a drive failed as I was doing a couple of OS upgrades."
"I would like to see active replication. I know that it's available now but I haven't tried it yet. I hope that it works."
"I would like to see LDAP for the management panel; I've been notified they might be currently working on it."
"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 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'm hoping to see Active Directory integration. Right now, you still have to use a local admin account to log in and manage everything."
"The front panel of the drive shelf doesn't always seat firmly."
"I would like them to improve the look of the product’s external casing and shelves."
"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."
"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."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"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."
"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."
"If the VNX had embedded encryption, that would be great."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do 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."
