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.

The creators of Qumulo were the ones who created Isilon, and I had a conversation with them, so any of the features within Isilon may need tweaking, but I think they resolved it here. In the year that I worked with it, I did not see anything that I had an issue with. The security is great, and it works with cloud technologies, being a hands-based tool, so you can use it with AWS or Microsoft Azure. It programs very easily. There are REST APIs, and there is a cloud connection. The management and program layer is made up of three capabilities: API, the command line, and a visual interface. In the year that I worked with it and brought it in, I think it has been effective. The only thing I would like to see added to Qumulo is for the interface to improve visually, more in line with vCenter, but that is just my thought. Overall, I appreciate it.
