摘要:
Methods, apparatus, and products for managing virtual addresses of blade servers in a data center are disclosed that include storing, by a blade server management module (‘BSMM’) in non-volatile memory of a blade server, a parameter block, the parameter block including one or more virtual addresses for communications adapters of the blade server and one or more action identifiers; detecting, by a BIOS module of the blade server upon powering on the blade server, the parameter block; disabling, by the BIOS module, in dependence upon the one or more action identifiers of the parameter block, an original address of at least one communications adapter of the blade server; and setting, by the BIOS module, an address of the communications adapter to a virtual address included in the parameter block.

摘要:
Failover of blade servers in a data center including powering off a failing blade server by a system management server through a blade server management module (‘BSMM’) managing the failing blade server, the failing blade server characterized by a machine type, one or more network addresses, and one or more storage addresses, the addresses being virtual addresses; identifying, by the system management server from a pool of standby blade servers, a replacement blade server, the replacement blade server managed by a BSMM; assigning, by the system management server through the BSMM managing the replacement blade server, the one or more network addresses and the one or more storage addresses of the failing blade server to the replacement blade server, including enabling in the replacement blade server the assigned addresses; and powering on the replacement blade server by the system management server through the BSMM managing the replacement blade server.
摘要:
Migrating port-specific operating parameters during blade server failover including querying, by a system management server of a data center, a switch for port-specific operating parameters of a first port, the data center comprising blade servers coupled for data communications to one another and to the system management server by a network, the system management server comprising a computer subsystem that automates server management processes in the data center, the switch comprising a data communications component of the network, the switch comprising ports, the ports comprising physical points of connection between the switch and blade servers, each port having associated port-specific operating parameters, the switch connected at the first port to a failing blade server; and assigning, by the system management server, the port-specific operating parameters to a second port in a same switch or another switch connected at the second port to a replacement blade server.

摘要:
A disk drive receives a request to write at least one block of a first block size, wherein the disk drive is configured to store blocks of a second block size that is larger in size than the first block size, and wherein the disk drive stores via emulation a plurality of emulated blocks of the first block size in each block of the second block size. The disk drive generates a read error, in response to reading a selected block of the second block size in which the at least block of the first block size is to be written via the emulation. The disk drive performs a destructive write of selected emulated blocks of the first block size that caused the read error to be generated. The disk drive writes the at least one block of the first block size in the selected block of the second block size. The disk drive sends a notification to indicate the performing of the destructive write.
