Quotes From Members Comparing Dell EMC Unity vs Huawei OceanStor

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
Pros
All-flash performance, Snapshotting capabilities and replication are all valuable features.We put the Unity on one of the file servers and the backup performance improved quite a lot.It has the same operating system for both file and block, and it actually simplifies everything. And it's much smaller compared to VNX.Provides good provisioning, allowing us to save space.We have simplified it down to where we're using one storage pool inside the Unity, whereas on the VNX, we had multiple storage pools. This has simplified that aspect for us. It would depend on each organization. We're heavy into VMware and this ties into it so simply. It's made it a lot easier for us. I create a datastore inside Unity, it just shows up in VMware. I love that tie-in.It's easy to handle for administrators and it's a unified system. It's not as complex as Celerra systems or CX4 Clariions to administrate. You can do everything with one GUI.Its main advantage over vSAN was the rebuild, the intelligence of the restoration in the event of a hardware drive failure and, of course, the all-flash solution.The flash aspects of the Unity make it incredibly fast. The fact that you get that much storage directly on what is basically a 3U box to us, that density has been really useful.

If your virtual machine that resides on it completely fills the storage space, thanks to it's built-in function of all-zero data space reclamation, you just have to ask to System Engineer to run a zero-free on hosts (thin provisioned) and you will get more space instantaneously.Stability: The product is designed to have always HA (High Availability) with redundant network and processors.

Cons
I think there are a couple of things on the file side that we're lacking from the VNX world. It would be nice if we got some of those back. I think there are limitations on how many file systems you can back up at a time. Whereas you can do, I believe, eight continuous per data mover on the file side on the VNX, you can only do something like two or four on Unity. If they could step up to that, that would be good.Scalability for the 650F is good, but I was expecting a little bit more.We had some issues recently because of a bug in the system. We were presenting LANs to the Unity array but I think it caused a disruption to the host. EMC did acknowledge it and provided an alternative way to do it.The monitoring part could be better. With EMC storage systems - or Unity and VPLEX, because I'm using them, for the moment - the monitoring part is very difficult. They should improve this to have a better reporting system.Replication with VMware - it's called the vSphere Metro Storage Cluster - is lacking in the Unity and is present in Compellent.Scalability is not good. We have a Unity 300, now we have to do a data-in-place conversion for the next upgrade because only 150 slots are supported, not drives, only slots.We've got massive issues at the moment with IBM AIX. It's not stable. We have a lot of disk errors, production crashes sometimes.I'd like to see more of the NVMe back-end for the flash. And the big deal with the PowerMax is that they've used all U2 drives so that they can avoid having to take it down. I see using M.2 and modular sections as being a real nice alternative that could be implemented in Unity at a fairly low cost.

Unfortunately, this product doesn't support Flash Disks, but it's IOPS capacity is a great compromise.Configuration complexity and the tools available.

Pricing and Cost Advice
The support you're getting with it is probably an underestimated value that comes with the box you're buying.What they really like is the easy licensing now - Dell EMC has caught up to a lot of their competitors - based on not having to charge for everything, and they can get everything in one bundle.The flexibility is important. We still have a lot of customers that have a use case for non-flash, yet you can also build the flash version as well.It's the performance combined with the gig-per-dollar value. That combination is superior to other storage options.At the end of the day, the licensing cost is key, because every customer has a pain point, that the cost of each piece is high. So if they would bundle everything in a package, that is how the competitors are selling their footprint.Pricing is as high as it has ever been for EMC.The pricing was quite okay compared to others. We probably got it cheaper because we were the first ones out of the gate, but I would say that it's good value for the money.For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products.
