Built-in software functionality includes automatic load balancing, snapshots and replication, Microsoft application integration, hypervisor-aware snapshots for VMware, multi-path I/O, consistency sets, and much more.
I was pleased with the Equallogic product line before, but this new PS5500E is impressive. One of the best things about Equallogic arrays is that the cost is inclusive of all of the software features – replication, for example, isn’t an additional license.
It’s also worth nothing that the hypervisor-aware snapshots for VMware are a feature of the latest software so if you’re already running a different model Equallogic SAN you can get this feature set by downloading and installing the new software.
EMC announced similar capabilities the next day.
Full disclosure, my company is a Dell Equalogic partner.
