A method and apparatus are disclosed for concatenating a first RAID and a second RAID. The apparatus includes a concatenation module and a direction module. The concatenation module concatenates a first Redundant Array of Independent Disks ('RAID') with a second RAID into a top-level RAID. The first RAID and the second RAID may have disparate operational characteristics. The direction module directs storage operations to one of the first RAID and the second RAID based on a direction policy.

An apparatus, system, and method are disclosed for memory upgrade optimization. A requirements modulereceives one or more of a capacity upgrade goalfor an overall capacity of the arrayand a performance upgrade goalfor an overall performance of the array. An analysis moduleidentifies a first potential capacity changethat can be achieved at a lower overall performance and a second potential capacity changethat can be achieved at a higher overall performance. A reconfiguration modulegenerates one or more of a first reconfiguration recommendationcalculated to yield an overall capacity improvement that takes into consideration the capacity upgrade goaland the first potential capacity changeand a second reconfiguration recommendationcalculated to yield an overall performance improvement that takes into consideration the performance upgrade goaland the second potential capacity change

An apparatus, system, and method are disclosed for memory configuration analysis. A classification moduledeterminesan overall performance of an arrayof memory devicesin a computer memory, wherein overall performance has a substantially inverse relationship with a highest quantity of members of a subset of the array and a substantially direct relationship with an individual performance capability of the members. A counting moduletakes a countof members of the arraywhose individual performance capability variesin a selected direction from the overall performance of the array. A comparison moduletakes a selected action such as issuing a memory configuration warningif the count crosses a predetermined thresholdcomprising a predetermined percentage for comparison with the count, as qualified by the individual performance capability, divided by an unqualified count of members of the array

A system, method, and program for managing a user key used to sign a message for a data processing system having an encryption chip are disclosed. A user is assigned a user key. In order to encrypt and send messages to a recipient(s), the messages are encrypted with the user key. The user key, in turn, is encrypted with an associated key. The associated key is further encrypted using an encryption chip key stored on the encryption chip. The encrypted messages are communicated to a recipient to validate an association of the user with the encrypted messages. The associated key is decrypted with the encryption chip key. The user key is decrypted with the associated key, and the messages are decrypted with the user key. Thereafter, validation of the association of messages with the user is removed by revoking the associated key. In a preferred embodiment, encryption resources are centralized in a server system having the encryption chip. The server system is coupled to and provides encryption services to a plurality of client systems. Messages to be encrypted are sent from a user's client system to the server system, which encrypts the messages using the encryption chip. The encrypted messages are sent from the server system to the client system, which then transmits the encrypted messages to their intended recipient(s). All data relating to the encrypted messages are erased from the server system after the encrypted messages are sent from the server system to the client system.

A method and apparatus are disclosed for automatic solid state drive performance recovery. A detection module detects a first SSD exceeding a fragmentation threshold. A plurality of drives comprises the first SSD and stores a data copy of data stored on the first SSD. An erase module erases a mapping table for the first SSD. The mapping table maps Logical Block Addresses LBA to physical addresses for the first SSD. A rebuild module rebuilds the data and the mapping table on the first SSD from the data copy.

Method and apparatus for automatic solid state drive performance recovery

The present invention provides a method and system for securing a computer. The method includes providing a zone of authorized operation for the computer; determining if a possessor of the computer is authorized to have possession when the computer and the possessor leaves the zone of authorized operation and pass through a portal; and allowing continued access to the computer without requiring a password if the possessor is authorized. The method and system is transparent to the possessor and provides no advantage in hiding the computer from the portal. This method and system may be easily applied in a corporate environment and is particularly apt for securing mobile computer systems.
