Dell Equallogic Firmware Hack for PS Series Storage

Dell Equallogic Firmware Hack for firmware 4.* and higher, there is a neat hack that I use on the PS5000 that escapes out to the linux bash shell.

You can escape out to the bash shell by typing the following:

1. login via the console, telnet, or a SSH session as grpadmin.
2. Type the following command at the command prompt:
   

support exec bash

I haven't explored much, but in my case I was instructed to restart the snapshot/replication service:
eqlinit restart-snap MgmtExec


BTW, you may have just voided your warranty , but probably not.

This matrix highlights the differing Editions and Pricing and prices of Vmware vSphere 4:

• Thin Provisioning is native to vSphere vCenter, not ESX. ESX/ESXi 3.5 can run witth Thin Provisioned virtual disks (VMDK).
• Storage vMotion is now NATIVE to the client interface (no more 3rd party plugin). Right-click, migrate, wizard walk, and your done.
• Very Important! FaultTolerence - Vmware says, "VMware Fault Tolerance is supported with virtual machines with only a single virtual processor. VMware Fault Tolerance ... requires at a minimum the Intel 31xx, 33xx, 52xx, 54xx, 74xx or AMD 13xx, 23xx, 83xx series of processors; and works with any future generation of these processors."
  

Before you expand your virtual infrastructure with new servers, make sure you're buying the correct supported processors Fault Tolerence is desired.
