Abstract

Solid-State-Drives (SSDs) constitute an exciting emerging technology. It is expected that SSDs will comprise a one or more solid-state memory-modules for storing data. This invention is to fully enable a SSD to have its own self-contained Encryption-Key-Manager (EKM) engine, called SSD-EKM. The SSD-EKM is removable, so that it may be stored in a vault when the library is not being used, such as during customer-engineer maintenance or upgrades, during shipment of the library, or during emergency shutdown of the library such as during a major storm or other natural disaster.

Solid-State-Drive Used as a Removable EKM Appliance in an Automated Storage Library

Solid-State-Drives (SSDs) constitute an exciting emerging technology. It is expected that SSDs will comprise a one or more solid-state memory-modules for storing data. This invention is to fully enable a SSD to have its own self-contained Encryption-Key-Manager (EKM) engine, called SSD-EKM. The SSD-EKM is removable, so that it may be stored in a vault when the library is not being used, such as during customer-engineer maintenance or upgrades, during shipment of the library, or during emergency shutdown of the library such as during a major storm or other natural disaster.

SSDs may comprise one or more NAND or DIMM (Dual In-Line Memory Modules) solid-state memory-modules. These memory modules could also be Millipede nanotech modules, or NOR or any other FLASH memory. SSDs of 16, 32, 64, 128, and 256 GB are commercially available. This capacity allows the implementation of both (a) an operating system (LINUX can come as small as 50 MB and AIX comes at about 2.22 GB), and (b) an EKM, with (c) plenty of room for any other support software or databases required.

This specific invention involves the removability of the SSD-EKM appliance so that it may be stored in a vault and thus protecting the entire contents of the library from unauthorized access when the library will not be in use. FIG. 1 shows solid-state drive (SSD) 100, comprising Serial ATA interface 101, processor 103, and one or more read-write memory modules 111-116, all contained in body 105. Interface 101 could alternately be USB, SCSI, iSCSI, SAS (Serial Attached SCSI), Fibre Channel, Ethernet, Fibre-Channel over Ethernet, Infiniband, etc.

In FIG. 1, one solid-state memory-module 111 contains Encryption Key Manager (EKM) 108. This EKM 108 does not encrypt the data itself. EKM 108 mana...
