Featured Reviews

MikaelHellström - PeerSpot reviewer
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.
Kiran Rajanna - PeerSpot reviewer
A seamless solution offering data encryption, quality service, and security encryption
Cloudian HyperStore needs to incorporate AI and predictive analysis. It would be helpful if the solution could analyze and predict how to manage data better. The end users should not have access to protected documents. They should be able to drop the documents. The capacity management dashboard can be better. We also want two-factor authentication using Google Authenticator or Microsoft Authenticator as MFA. Hence, the user would access the console not just by logging in with a password and username but with third-party applications as well.
Scott Taylor - PeerSpot reviewer
Manages large data sets efficiently with hybrid cloud integration
My organization is quite large, with about 30,000 employees. The growth has been substantial in areas such as radiology and genomics. One of the best features we've utilized recently is offload to cloud pools due to capacity constraints on-premise. We didn't want to expand Dell PowerScale (Isilon) straight away, so we utilized cloud pools to offload some data to Azure. That's really saved us in certain areas as we didn't have funding to expand Dell PowerScale (Isilon) until next year, which is why we utilized the cloud pools functionality to offload.
