Featured Reviews

MikaelHellström - PeerSpot reviewer
IT Manager at Regin Dalarna
Has handled backup storage needs reliably and supports seamless upgrades
In environments requiring high throughput and low latency, Pure Storage FlashBlade provides high throughput and normal latency, but we do not have any application that requires low latency right now, so the latency of three to five milliseconds is considered kind of high. Pure Storage FlashBlade's ability to integrate with enterprise applications is not important for us, as we only want to present an S3 bucket for our backup, which we have done, and it works very fast. We use the Purity software's data reduction techniques; we have a backup software that compresses everything before sending it to the S3 bucket, achieving a data reduction of 1.1 to one. I would recommend Pure Storage FlashBlade to other companies because it's a very fast and scalable solution for anyone who needs it. On a scale of 1-10, I rate this solution an 8.

Flexibility and reliability have supported seamless data growth
I cannot think of anything to improve about Dell PowerScale (Isilon). The hardest challenge we have is due to how we've bought things over time. The way that we moved to the PowerEdge platform for the newer systems creates a scale problem as I still buy the older style systems, which are more dense storage. They're different chassis, so the problem we run into in the data center is the depth of the actual equipment. The newer equipment, if we buy an FX910 or a 900, it's a lot shorter in scale than if I buy an 83,000, which is much bigger. This makes it more complicated for deployment.
Michael Lopez - PeerSpot reviewer
Sr Systems Engineer at a outsourcing company with 10,001+ employees
Has reduced storage costs and improved snapshot management for large data workloads
The advanced features of NetApp StorageGRID which our upper management wouldn't agree to use, include the S3 feature. We are heavy into AWS, and my thoughts were to develop a small dev environment or even a POC environment on-prem. That's still up in the air as we continue on. Currently, AI has taken over everything with a focus on AI. The upgrades of NetApp StorageGRID present a challenge. It's a rolling upgrade, node by node. At one point, one node would not upgrade. The positive aspect is that it didn't take down the entire environment. The environment remained functional on two different versions. The scalability of NetApp StorageGRID has been proven as we've expanded twice. We started with six or seven nodes and have grown to 15 nodes. It does take time for synchronization to complete. From what I've seen, it took a couple of months for it all to sync up once adding nodes. However, it was transparent. It captured the addition and performed effectively, all happening in the background, steadily and surely.
