Storage of keyID in customer data area |
摘要 |
A key identifier for an encryption key repository is stored with customer data on a logical device. When the customer data is compressible, the key identifier is stored in space freed by compressing the customer data. When the customer data is not compressible, a portion of the customer data is copied to a key record in the key repository identified by the key identifier, and the key identifier overwrites the copied customer data. |

1. A non-transitory machine-readable medium on which instructions are stored, the instructions comprising instructions that when executed cause a network device to:
copy a first customer data from a first portion of a customer data area of a logical device to an encryption key record of a key repository corresponding to a key identifier; overwrite the first customer data in the first portion of the customer data area with the key identifier; compress a second customer data in a second portion of the customer data area; and store a key identifier data corresponding to the key identifier in the second portion of the customer data area if the act of compressing a second customer data shrinks the size of the second customer data by at least the size of the key identifier data. |
