HP AARTDZHTE/958000284008 BBCredit Allocation for ports, Nvram caching, Robust large fabrics

BB_Credit Allocation for ports

With firmware 07.00.00 and later, this 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.

Changing password in CLI

When users are prompted to change the password when logging into the Command Line Interface (CLI), they can enter the default password (password). This will be accepted, however at the next login they will again be required to change the password if it is still the default password.

When users enter the default password when prompted to change the password, new Security Log entry 10203, Default Password Not Changed, is posted.

Zoning enhancement to reduce fabric congestion

In Homogeneous Fabric mode, an enhancement was added to reduce unnecessary fabric congestion when performing fabric-wide zoning operations that impact the Default Zone. This enhancement limits the number of members allowed in the Default Zone to

64.When the firmware detects a zoning operation that would cause the member count in the Default Zone to exceed 64 (such as deactivating an active zone set that has more than 64 members), the operation is aborted and the user interface (HAFM 8.6 or EWS) displays the following message: Zoning request denied: Operation will cause the Default Zone to exceed its limit of 64 members.
