Featured Reviews

Jaehoon Oh

Chief Technology Officer at Lambda256

Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades

I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

Naguib Wasef

Collaborate effectively with partners and benefit from robust data management capabilities

The functions of HPE StoreOnce that I find most valuable are its deduplication and replication options. These features save data and reduce the size of data significantly. If the actual size for backup data is 100 terabytes, using StoreOnce, it will be around less than 10% of the original size due to the 1 to 10 deduplication ratio. So, compression and replication are critical features I appreciate. Additionally, adaptive backup and restore capabilities of HPE StoreOnce are indeed very helpful functions. As I know from my technical team, the process is very easy for end users because the GUI and user experience with StoreOnce are straightforward. They can restore their backups at any time. An important feature of StoreOnce is that they can reserve an amount of storage capacity as protected capacity for a limited time, safeguarding their data against intrusion and other interactions. Based on feedback from customers, StoreOnce is regarded as a highly useful solution for backup. I am satisfied with the security aspects of HPE StoreOnce, but it's crucial for any company to maintain a multi-layer security approach. Starting with a firewall is essential for maintaining their environment. Additionally, security features on StoreOnce are useful. I believe that no company should rely solely on one layer of security; they should adopt a multi-layer security strategy that begins at the network level and extends to their internal solutions.
