Equallogic’s are very nice boxes; fast, robust and very scalable (linear!; adding an enclosure adds processing power spindles and cache!). They don’t have licenses to enable features, WYSIWG!.
But sometimes a bit of a “blackbox”. This has been greatly enhanced by the release of the Equallogic SAN HQ Software.
It would be nice however if they would support synchronous replication between two groups, they do support a-synchronous replication though. And if they were a bit more flexible on the networking side by supporting VLAN tagging for example.

For the people who want to have a bit more insights:

SSH into your Equallogic group, login and enter “support”.

Be aware of the following message!

You are running a support command, which is normally restricted to PS Series Technical Support personnel. Do not use without instruction from Technical Support.

When running “cachetool”:

When running “netstat -i”:

There are more commands to discover. Try TAB completion and mind the difference between “Bad Command” & “Ambigious command”. These commands are not shown when using “help” and most have a -? or -h option.

AGAIN: ONLY DO THIS ON TEST SYSTEMS AND WHEN YOU KNOW WHAT YOU’R DOING ONLY!… Don’t come whining here if stuff breaks…
