The main issue was that when there were new storage solutions technologies available on the market, Dell EqualLogic PS Series was not compatible with the latest products. Right now, we have a storage device that offers deduplication along with uniform management software. The tool's front end was not unified, and it was an issue for my company. The only challenging part in the tool was related to some site recovery area. In order to exploit the site recovery area, my company had to purchase additional VMware products. My company did not venture too deep into the tool because we were happy with the low-level integration offered by Dell EqualLogic PS Series. I wish Dell EqualLogic PS Series could integrate well with VMware or ESXi so that my company doesn't have to purchase additional licenses from VMware.
