PS6000xv really poor performace

We have 2 eql 6000XV  1 has been used in production (raid50) for years, and it's been great.  The 2nd PS6000xv is relatively new, from ebay.   I've interratged into the force10 switch and our vmware environment the same exact way as the production ps600xv.  Now that I'm booting up the first VM on it, it feels super slow.  Drive 0 seems to NOT be blinking with the rest of the drives.  it's not the spare.  this is setup in a RAID6.  all drives (minus the spare) will blink in unision during IO operations, drive 0 seems to march to it's own beat ?!!?!  then it will sync up for a bit..  strange, but maybe not relevant.

I have a iscsi connection to a 200gb volume on my local PC. .. just dragged a 3gb file to the iscsi drive.  writes at about 30MB/s ...   dragged it back to my desktop at about 8/MB/s  HOLY cow, that's bad.... I'm 1gb eth,  my previous experious using iscsi on windows was about FULL gb speed... 90/MBs ish.  HELP.

This unit is  out of warranty, but I'm willing to pay the EQL team for some troubleshooting.  any ideas on above issue?
