DS8000 Host AdapterPort Assignment and HA Card Installation Sequence

DS8100– All host adapter cards are installed in base frame (Rack 1)– Optional expansion frame does not support additional host adapter cards– Maximum port count is 64

DS8300– Host adapter cards may be installed in Rack 1 or Rack 2 (if present)– Maximum port count is 128

DS8700– Host adapter cards may be installed in Rack 1 or Rack 2 (if present)– Rack 1 optionally may have only one pair of I/O enclosures (FC #1301 Qty 1)– Maximum port count is 128

DS8800– Host adapter cards may be installed in Rack 1 or Rack 2 (if present)– Rack 1 optionally may have only one pair of I/O enclosures (FC #1301 Qty 1)– Maximum port count is 128

DS8000 Host AdapterPort Assignment Best Practices

Isolate host connections from remote copy connections (MM, GM, zGM, GC and MGM) on a host adapter basis

Isolate CKD host connections from FB host connections on a host adapter basis

Always have symmetric pathing by connection type (i.e., use the same number of paths on all host adapters used by each connection type). For z/OS, all path groups should be symmetric (i.e., uniform number of ports per HA) and spread path groups as widely as possible across all CKD host adapters.

When possible, use the same number of host adapter connections (especially for System z) as the number of connections coming from the hosts.

Size the number of host adapters needed based on expected aggregate maximum bandwidth and maximum IOPS (use Disk Magic or other common sizing methods based on actual or expected workload.

Sharing different connection types within an I/O enclosure is encouraged.

When possible, isolate asynchronous from synchronous copy connections on a host adapter basis.

When utilizing multipathing, try to zone ports from different I/O enclosures to provide redundancy and balance (i.e., include port from a host adapter in enclosure 0 and enclosure 1).

DS8000 Host AdapterPort Usage Best Practices

For optimal performance

– Avoid using adjacent ports (if possible)

– For 8 port cards, use each 4 port set equally

– Follow the following plug order sequence

Plug Order

(4 port card)

Plug Order

(8 port card)

Port 0 1 1

Port 1 3 5

Port 2 2 3

Port 3 4 7

Port 4 2

Port 5 6

Port 6 4

Port 7 8

DS8000 Host AdapterPort Usage Best Practices

For System Z

– Place each path in a path group in a different I/O bay.

– Do not have two paths from the same path group sharing a card

– This will balance the workload over the available HBAs

DS8000 WWPN Determination*

1/12/2011

DS8000 WWNN is on: 50:05:07:63:0z:FF:Cx:xx

The z and x:xx values will be a unique combination for each machine and each Storage Facility Image (SFI).

Each SFI has its own WWNN. The Storage Unit itself also has a unique WWNN.

Use lssi to get the SFI WWNN (don’t use lssu):

DS8000 WWPN is a child of the SFI WWNN, based on 50:05:07:63:0z:YY:Yx:xx

Take the z and x:xx value from the WWNN and use the YY:Y location derived from the port location as per the diagrams on the next five pages.

All DS8000 diagrams are from a REAR view of the machine.

There are no differences for WWPN determination between DS8100, DS8300, DS8700 and DS8800
