Unified file sharing has simplified multi-tenant access and has delivered seamless data replication
Dell PowerScale (Isilon) includes its replication features; when we decommissioned our old Isilon cluster, we migrated all of the data to a new cluster, and it was pretty seamless. All you have to do is create the certificates and make those certificates available to the target cluster, then initiate a few jobs. The inter-cluster replication feature, called SyncIQ, allows you to set up all of the jobs and move your data entirely, either timely or all at once. Another suitable feature is the ability to back up your directories; you can take snapshots for all of your directories, and in fact, I believe you can take around a thousand snapshots for a single directory. The inter-replication, geo-replication is one feature. Dell provides a variety class of hardware suitable for your workloads, meaning if your data is just lab and not critical, you don't have to spend much on the hardware; conversely, if your data is mission-critical, you can buy a high-performance node from Dell. Additionally, you can span Dell PowerScale (Isilon) cluster to a large number of nodes, and code upgrades are pretty smooth because all protocols will be upgraded under a single piece of code. Since it provides a single file system that spans across the nodes, you don't have to worry about that directory structure being separately created on individual nodes, making it a fitting solution for a data lake solution because you can access the same data from multiple protocols.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"All features are available through NetApp storage devices and all the protocols are on the same box, with deduplication and snapshot features available through the NetApp FAS series."
 

Cons

"That said, for the other security features, it would be helpful if Tenable - and I know it's outside the scope of this question itself - had Isilon-specific plugins."
"Improvements could be made on the object storage side."
"The product itself is capable of very much, but the initial deployment experience can be lacking possibly because it does not incorporate any design phase."
"The solution’s interface and pricing could be improved."
"I would appreciate seeing improvements in Dell PowerScale, particularly because it has been weak with small file writes."
"Dell PowerScale needs to reduce its price."
"The technical support is average. There are certainly not the best that we have ever dealt with, but far from the worst ones."

"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"The price of Dell PowerScale (Isilon) is reasonable."
