HP 316095-B21 - StorageWorks Edge Switch 2/24 Примечание к выпуску - Страница 22

Firmware 05.03.01-01 is available for the Edge Switch 2/24, and ﬁrmware

05.05.01-01 is available for the Edge Switch 2/12. These versions are installed only on

the Edge Switch 2/24 and Edge Switch 2/12, and only when these switches are placed

in a M-Series SAN running 05.02.00 ﬁrmware. A copy of these versions of ﬁrmware,

are contained on the HP StorageWorks edge switch documentation and ﬁrmware CD

(Part Number 524-000001-005).

Reinstalling feature licenses

Feature licenses (or keys) must be reinstalled after performing a factory reset on a

director to regain use of the licensed features (e.g., SANtegrity Binding).

CTP controls port lights

Port lights on the edge switch and director products are controlled by the CTP

functionality. Certain activities such as ﬁrmware updates, IPLing the CTP, or switching

over to the backup CTP (director) can cause these port lights to extinguish momentarily

until control is reasserted by the CTP. The actual Fibre Channel trafﬁc is not affected

during these times.

BB_Credit Allocation for ports

Firmware 07.00.00 or later, supports the ability to allocate a speciﬁc number of buffer

credits per port. This feature provides beneﬁt primarily in the Edge Switch 2/12 and

2/24 switches, where a single pool of buffers is shared among all ports. Users will now

be able to allocate buffer credits only where needed. For the Director 2/64, Director

2/140, and Edge Switch 2/32 switches, this enhancement simply allows more granular

conﬁguration options for users who want complete conﬁguration control.

NVRAM caching

All writes to non-volatile memory random access memory (NVRAM), which stores

conﬁguration data, are now cached to prevent possible corruption of information. Prior

to ﬁrmware 07.00.00, a small window existed where a switch power-down during an

NVRAM write could enable the conﬁguration default settings when the switch is powered

back on. All switches and directors are now protected from potential interruptions to

NVRAM updates.

Robust large fabrics

Numerous low-level enhancements and optimizations have been made to improve the

stability of directors and switches in fabrics containing high populations of devices.
