Supported devices
The 6Gb SAS BL Switch supports the following types of devices:
•
“Shared SAS storage enclosures (P2000 G3 SAS MSA arrays)” (page 6)
•
“Zoned SAS storage enclosures (MDS600, D6000, and D2600/D2700 drive enclosures)”
(page 6)
•
For information about cabling and configuring the switch and any attached devices, see
“Connecting cables to the switch” (page 15)
.
Shared SAS storage enclosures (P2000 G3 SAS MSA arrays)
When shared SAS storage enclosures are attached to the switch:
•
The storage enclosure includes an embedded RAID array controller, which is used to
configure the logical storage units (LUNs). An example of a shared SAS storage enclosure
is the HPE P2000 G3 SAS MSA Array System.
•
The BladeSystem server blade must have a RAID array controller installed, which
communicates with the RAID array controller in the storage enclosure, but it is not used for
its RAID configuration capabilities.
•
The SAS BL Switch and the connected SAS storage are configured using switch-port zone
groups. The entire storage enclosure connected to that switch port is visible to all c-Class
enclosure blade ports (server bays) granted access to the zone group that includes that
switch port.
NOTE:
Unused switch ports can be included in a zone group, to help plan for future growth.
•
Server bays that need access to an external storage enclosure must be assigned the
appropriate zone group.
◦
A server bay can be assigned multiple zone groups.
◦
A switch-port zone group can be assigned to more than one server bay.
◦
Unpopulated server bays can be assigned a zone group.
•
Disk drives in the storage enclosure are configured into logical units (LUNs) using a
storage-enclosure based utility such as the HPE Storage Management Utility (SMU). Access
or restrictions to the LUNs is controlled through mappings or other presentation methods,
which grant specific server bays access to specific LUNs.
Zoned SAS storage enclosures (MDS600, D6000, and D2600/D2700 drive
enclosures)
When zoned SAS storage enclosures are attached to the switch:
•
The storage enclosure includes I/O modules (does not include a RAID array controller).
Examples of zoned SAS storage enclosures are the HPE MDS600, HPE D6000, and HPE
D2000 (D2600/D2700).
NOTE:
The MDS6000 is a 3G device; when connected to the 6G SAS BL Switch, all data
traffic will be reduced to 3G.
•
The BladeSystem server blade must have a RAID array controller installed, and is used for
its RAID configuration capabilities.
