Abstract
Official abstract text for this publication.
An I/O module is provided to service I/O requests from a host to access storage media. Data blocks of the storage media are encrypted with an old key, and the I/O module performs key rotation to cause data blocks to be re-encrypted with a new key.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of performing key rotation in a computing environment having a host, a first storage media, first and second I/O managers coupled between the host and the first storage media, a second storage media that mirrors the first storage media to create a mirrored volume, and a third I/O manager coupled between the host and the second storage media, the method comprising: signaling the second I/O manager to suspend servicing I/O requests from the host to ac…
