Map Devices; Xstreamcore Mapping; Sas/Sata Device Mapping - ATTO Technology XstreamCORE FC 7550 Installation And Operation Manual

After getting an IP address and logging into the ATTO XstreamVIEW™ System Manager, you have options to map devices so that th e
XstreamCORE can access the devices in your network.
The ATTO XstreamCORE allows parallel SAS/SATA devices to
participate in a Fibre Channel arbitrated loop or on a fabric.
Fibre Channel and SAS/SATA use different models to address
devices. The XstreamCORE translates between these
addressing models.

XstreamCORE mapping

WWN:
To identify each Fibre Channel device while addressing, each
Fibre Channel device is assigned a unique World Wide Name
(WWN). The 64-bit WWN has the following format:
Field WWN Company ID
Name Format
Byte 0 1 2
Value 20 00 00

SAS/SATA device mapping

SAS/SATA devices connected to the XstreamCORE are viewed
as Fibre Channel LUNs to the host computer.

Map Devices

The ATTO XstreamVIEW™ interface displays the current
mapping information for SAS/SATA devices. Refer to
Options.
Drive Map Director
Drive Map Director uses SMP to provide a predictable
mapping structure for devices attached to the XstreamCORE
FC 7550 and XstreamCORE FC 7600. To use this feature, drive
enclosures must support SAS expanders with SMP protocol
such as the HP StorageWorks SAS JBODs. If SMP supporting
expanders are not present in your storage system the
XstreamCORE will revert to the AutoMap feature (see
Automap devices)
SCSI commands sent to offline devices are rejected.
