摘要： A memory tag mechanism creates a logical memory tag of a first length that corresponds to an I/O address of a second length. The memory tag is “logical” because it does not represent physical memory. When an I/O adapter device driver that expects an address of the first length is invoked, the memory tag is passed. When the I/O adapter device driver makes a call to the partition manager to convert the address of the first length (i.e., memory tag) to an I/O address of the second length, the partition manager detects that the passed address is a memory tag instead of a real address, and returns the corresponding I/O address. In this manner existing device drivers that expect addresses of the first length may be used for redirected DMA, which allows performing DMA operations directly from a shared I/O adapter in a hosting partition to memory in a hosted partition.

摘要： A hosting partition update mechanism allows updating I/O capability of a logically-partitioned computer system in a way that minimally affects the performance and availability of I/O in the computer system. When an update is needed, a new hosting partition is created with the desired update(s). I/O adapters in the current hosting partition are then migrated to the new hosting partition. The migration of an I/O adapter from the current hosting partition to the new hosting partition is relatively fast, thereby minimally impacting system performance and availability of I/O. Once all of the I/O adapters have been migrated to the new hosting partition, the current hosting partition may be kept as a backup, or may be eliminated. Providing a new or backup hosting partition allows updates to be performed in the new or backup hosting partition in a non-disruptive manner while the current hosting partition continues to service I/O requests.

摘要翻译：托管分区更新机制允许以最小程度上影响计算机系统中I / O性能和可用性的方式更新逻辑分区计算机系统的I / O能力。当需要更新时，将创建一个新的托管分区，并具有所需的更新。当前主机分区中的I / O适配器随后被迁移到新的主机分区。将I / O适配器从当前主机分区迁移到新的主机分区相对较快，从而最小程度上影响了系统性能和I / O的可用性。一旦所有的I / O适配器都已经迁移到新的主机分区，当前的主机分区可能会保留作为备份，或者可能被删除。提供新的或备份的主机分区允许在新的或备份主机分区中以不间断的方式执行更新，同时当前的主机分区继续维护I / O请求。

摘要： Methods, apparatus and computer program product implement enhanced dynamic copy-on-write storage compression. For a write operation, a freed block is detected by the COW storage for compressing freed blocks from the COW storage. Responsive to the detected freed block being a previously written block in the COW storage, the previously written block in the COW storage is deleted from the COW storage. Responsive to the detected freed block not being a previously written block in the COW storage, the block is marked as zero in the COW storage.
