  New SAN setup – Configuration issues

  Posted by David Wiles on July 15, 2013 at 8:05 am

  Hey guys,

  I’ve got a problem with the configuration of my SAN causing it struggle connecting over fibre.

  Gear –
  Storage : Infortrend ESDS S16F-R2840-4 with 12 x 3tb Seagate constellations
  Primary MDC : xserve – ATTO 8b fibre
  Clients : 2 x Mac Pro – ATTO 8gb fibre
  Software : MetaSAN
  Interconnects: None – All gear going straight into Infortrend.

  Issue : Only the primary MDC can connect to the SAN – The clients see the enclosure but no ‘direct access device’ which means MetaSAN defaults to metaLAN and I only get gigabit ethernet speeds. Server manages 650mb/second.

  I assume I have to configure the Infortrend to act as a switch so multiple devices can mount the volume, but I’m not sure where i’ve gone wrong.

  A snapshot of my Config:
  Host connection parameters :

  Maximum Queued I/O Count : 1024
  Luns per Host SCSI ID: 8
  Max number of Concurrent Host-LUN connection : 4
  Number of Tags reserved for each Host-LUN connection : 4
  Fibre connection Option : Loop only
  Cylinder/Head/Sector : Variable

  Peripheral Device Type Parameters

  Peripheral device type: Enclosure Services Device (Type=0xD)
  Peripheral Device Qualifier : Connected
  Devices Supports Removable Media : Disable
  LUN Applicability : First Undefined LUN

  I’ve got experience with Apples xsan fibre (Couple of previous installs, including another concurrently) and my immediate temptation is to put in a switch but I’m told with the Infortrend that shouldn’t be necessary.

  Any help appreciated!
