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.

Has supported long-term data protection and backup while requiring better part availability and pricing options
For monitoring purposes, we normally use flash access storage exclusively. We utilize a hybrid system because we need performance, combining NL-SAS for the volume and SAS flash to use as a fast cache system that provides more IOPS. We normally implement RAID 10, which we prefer over RAID 6's n plus 2 combinations. We utilize it for data redundancy, even with write intensity on. Regarding the unified storage architecture for NetApp FAS Series, we normally opt for exclusivity unless budget constraints exist. Our IOPS are very high, reaching somewhere about 50k to 150k or 1.150k. The high performance ensures minimal latency. An advantage we've seen with NetApp FAS Series is that snapshots provide very rapid backup and fast recovery. We basically use snapshots for data protection as first-level protection, with deduplication between the two storages serving as second-level protection.
