Hassan_Zaki - PeerSpot reviewer
Integrated AI and clustering enhance storage operations effectively
I promote and recommend Dell PowerStore for all workloads to my clients and customers. Most of my customers have one appliance per site. Approximately 80% of my customers have Dell PowerStore implemented in their data centers. We always use CLS as another Dell solution for cybersecurity and data security. The CLS is integrated with the Data Domain, PowerProtect Data Domain, not with Dell PowerStore. Windows, Linux, and some customers use Red Hat or SUSE. We have many operating systems working with Dell PowerStore in the same environments and data centers. CloudIQ and Storage IQ are used by some customers, but Apex AIOps has not been widely adopted yet. Dell PowerStore has integration with VMware and Kubernetes. Most workloads work fine and have very good integration with Dell PowerStore, except for one or two specific workloads in the market. On a scale of one to ten, I rate Dell PowerStore a nine.
