Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."It gives us capacity planning."
"I have seen a huge increase in speed and performance on our databases."
"The most valuable features of Pure Storage FlashArray are the management view of the solutions, ease of provision, and deprovision, it is fantastic."
"Lone segmentation is simpler and more agile. It's improved the velocity in overall provisioning from project to operation."
"I like FlashArray's ActiveCluster as well as its snapshot and cloning capabilities."
"Running SAP on Pure Storage helps a lot without doing any further tuning to improve application performance. Our internal clients are happy."
"Access speed and power consumption are most valuable."
"Pure Storage FlashArray's overall speed is its most valuable feature."
"The most valuable feature is that the solution is a hybrid system, so you can do both block and file storage."
"It is scalable, and we usually recommend Dell Unity XT to small and medium companies."
"All-flash performance, Snapshotting capabilities and replication are all valuable features."
"Dell EMC Unity XT has good integration with VMware."
"We like the way it integrates with our environment. These features help us use multiple soft applications. The new features of going off the grid and replicating really help us. They give us an advantage versus traditional storage resources."
"We have resolved IT challenges with this solution. It sped up our environment. We went from spinning disk to all-flash, which reduced our footprint."
"The replication is big for us. We use file services on Unity and it has a really nice file services interface. It's also easy to manage. It's really easy in terms of provisioning, replication. There are no real tricks to it. It's just easy."
"Their support cases are all handed through the portal. The support contacts me when they need to do upgrades. It has been great. It's all very well-handled, scheduled, and performed."
"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."
"Integration with VMware"
"Good performance for VM environments"
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"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."
"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."
"It is very stable even during multiple power failures."
"It needs to improve its price."
"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."
"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."
"There are many features which need to be added, particularly on the replication side."
"I would like to see more detailed reporting on the data. However, it would be nice to know what are the exact VMs usage after deduplication and/or what that VMs actual latency and bandwidth is, outside of VMware."
"It would be nice to have a better view of the allocated capacity on their Platform as a Service solution because we have to do some manual calculations to understand how much we are going to pay every month to use the storage that is allocated."
"There's always an opportunity for new feature functionality."
"The price of the solution can improve."
"In the dashboard there could be notification of duplicate files and the like, so we don't have to rely on Windows to do that."
"It needs deduplication. We'd like to have the dedupe capabilities in the Unity."
"The solution should include a free process in the HPE portal that uses serial numbers to verify that hardware is genuine."
"The NAS capabilities of Unity - I have to say there are a lot of things I miss. For example, deduplication for hybrid. I have tons of customers with VNX and dedupe. These customers achieve around 50% dedupe efficiency and they mostly use them for archive. If you're talking about 50TB of NAS, which is stored in a 25TB repository, which is very economical, and you can not provide that in a Unity hybrid box, you have problems."
"Our customers are mostly happy with Unity except for the price. We primarily sell to enterprise companies because small companies cannot afford it."
"Compression and block deduplication on non-all-flash solutions."
"The VNX reporting is much more granular, versus the Unity reporting."
"I think that they could do a better job of testing on the back-end, for the code revisions. I've heard of some issues down the line where people have upgraded to the latest code and there were bugs in it, and they had to release a subsequent code fix."
"Poor connection to FC."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do 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."
"The CLI could be better documented, like with VMAX."
"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."
"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."
"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."
"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."

Unity series is re-engineered VNX, so the Unity is newer … it makes better use of flash, active – active , dual controller mode; better price point , configurations solid upgrade from the VNX
Go for Unity. It’s the newest model and the base software is now better than VNX.
Unity is newer. Go with newer of the 2 if these are your only options.
Both systems are good middle storage systems but the unity family is latest.
The unity 400 is an hybrid flash where you can install classic HDD and
SSD. So you can reduce costs and optimize your storage for your
requirement.
Some function (that will be available in 4Q17) are interest like :
* support for inline compression,
* deduplication
* zero detect.
Deduplication is an expensive cycle system and I suggest to use it with
SSD. These function deduplication and zerodetect produce an hard
reduction of user space and if you need to reduce it without lost
performances I suggest an all-flash system and not an hybrid. Zerodetect
can give benefits, for istance in VmWare enviroment, for istance when
you inizialize a volume; or when you copy data from an old storage
systems to this one.
This systems can grow up 16 PB
VNX family is an old architecture, but has good point for use it. Has a
low cost, you can install some SSD. This system scale up to 0,5 PB
Which is better storage system for you ? It depend where you use this
storage system.
In other words if this storage system is the core of your IT
architecture and you are thinking :
* that you need of high performances,
* that it will grow in a couple of mounth, but you do not know when,
* that on this system there is the virtual server workload
So use Unity!
If this storage system is one of more storage systems in your storage
enviroment where you need to a lot of performances but it will not grow.
Use VNX!
With Dell EMC, you can continue to work with the midrange and ensure high performance. Dell EMC Unity 400F environment SAN and high performance for NAS. Dell EMC Unity 400F Performs Replication operations on Snapshot (Snapshot), Local Area Network and Remote Network. In addition, systems such as VMware, Microsoft and OpenStack can work.
First of all, DELL EMC will announce the end of life of VNX in JAN so take in consideration this point.
Secondly, UNITY is better than VNX in terms of performance, scalability and price. However my advice to you is to be “modern” and go for Unity 350F ALL FLASH, from now on consider the all flash in everything in case of using virtual san or SAN storage. Unity 350F is the same cache 96GB as unity 400 hybrid and scalability is more and more better than 400 because nowadays the single SSD capacity up to 15 TB so it will scale more. In addition to, All Flash models contains unified, deduplication, compression and dynamic pools and this is the best option in All flash because goodbye for the traditional way of building a pool with a hot spare and a parity, now you can put the exact capacity you want by adding one disk or 2 or whatever you want not like the old days build the same pool as the previous one installed in the storage box.
To sum up, please reconsider your choise and put the ALL Flash unity as option 1.
EMC VNX 2500 or EMC Unity 400. Which one is the newer and better Storage and why?
Which Storage is the latest and which one functions better and Why?
Unity is the newer box and I think it will replace the Vnx family eventually.
Unity support SAN, NAS and ISCSI also Flash and Standard disks .
The only drawback I know of is that Unity uses TLC for the flash disks
As a new purchase, the Unity will have a longer support life as the VNX line will gradually be phased out.
The management software in the Unity is newer and easier to configure and manage, which is often important in a smaller organisation that does not have SAN skills. If you decide to take an EMC Unity array there is a new HMTL5 GUI versus the VNX 5200 which uses now out of date Java versions.
Both the Unity 400 and VNX5200 arrays are widely installed, reliable and both make excellent storage platforms for production applications and virtualised environments.
