I thought I'd check back and see if keeping 5 shelves per controller chip was still the recommended method, or if using more with the new OS is OK.

Thanks,

Jeff

Greetings,

A while back there was a known issue with the SAS controller.  Each chip that controlled 2 ports would only address 128 devices.  That included shelf controllers so technically 5 ds2246 shelves would exceed the limit and could cause some slowness.

I was told that they changed this behavior in 8.1 and possibly upgrading the firmware, so that it only kept active devices in the list.  I was told those devices would be removed when not active and so there was no need to keep the smaller shelf limit.

Is this the case, or do I still need to try to limit each chip to 5 shelves or less?  I'm running 8.1.2P4 and the cards are running 01.11.00.00.

Thanks,

Jeff
