Abstract: A sequential buffer for a magnetic tape data storage system comprises a plurality of segments. A buffer management system buffers data in the sequential buffer, conducting a data transfer process. Subsequently, some of the buffered data is maintained in some, but less than all, the segments of the buffer. Additionally, the maintained buffered data is indicated as VALID data. Thus, a subsequent process may be conducted directly using the data maintained in the buffer, and avoids moving the tape to reread the data.

Abstract: Disclosed is a technique for data synchronization. A first identifier is determined for a portion of data at a first source. A second identifier is determined for a portion of corresponding data at a second source. The first and second identifiers are compared. When the first and second identifiers do not match, the portion of corresponding data at the second source is replaced with the portion of data at the first source.

Abstract: PROBLEM TO BE SOLVED: To provide an automated data storage library system efficiently using a common element. SOLUTION: A drive resource provider 35, upon receiving a request for a drive when all of the drives of the pool are allocated, holds any mount of a portable data storage cartridge relative to the request, releasing the hold when a drive is allocated. Furthermore drive image providers 30 of a virtualization system for an automated data storage library provide an image of a fixed plurality of virtual data storage drives with fixed identifications to a host application. The drive image provider 30 characterizes and directs communication between the host and the dedicated drive as a fixed virtual drive; and prior to the dedication of a drive, characterizes the virtual drive to the requesting host application as "not ready".

Abstract: VARIOUS DATA STORAGE FORMATS HELP TO EFFICIENTLY LOCATE, READ, AND WRITE USER DATA STORED ON MAGNETIC TAPE MEDIA (206). A TAPE (400. 800, 900) IS FORMATTED BY WRITING MULTIPLE SEGMENT—HEADERS (408—4 1 1), FREE FROM ANY INTERLEAVED ACCESS OF USER DATA. ADJACENT SEGMENT—HEADERS ARE SPACED BY A PREDETERMINED INTERVAL TO DEFINE MULTIPLE DATA STORAGE SEGMENTS. SEGMENT—HEADERS ALL CONTAIN A UNIQUE KEY (408C), WHICH IS COPIED INTO A KEY INDEX TO IDENTIFY VALID SEGMENTS. AFTER FORMATTING, NORMAL TAPE ACCESSES CAN BE PERFORMED. WITHOUT ERASING ANY O]D HEADERS OR DATA, A NEW FORMATTING SCHEME CAN BE ESTABLISHED BY WRITING NEW SEGMENT—HEADERS ON THE TAPE. THE NEW SEGMENT—HEADERS INCLUDE A NEW UNIQUE KEY, REPLACING THE PREVIOUS KEY IN THE KEY INDEX. PREVIOUS SEGMENT—HEADERS STORED ON THE TAPE ARE IGNORED, SINCE THEY LACK THE UPDATED KEY. SEGMENTS MAY BE SELECTIVELY GROUPED TO PROVIDE INDEPENDENTLY ADDRESSABLE PARTITIONS. MAPPING BETWEEN SEGMENTS AND PARTITIONS CAN USE A FIXED RELATIONSHIP (E.G. ONE-TO—ONE), OR EACH PARTITION MAY BE VARIABLY SIZED ACCORDING TO THE AMOUNT OF DATA TO BE STORED THEREIN. VARIABLE—SIZED PARTITIONS MAY BE AUTOMATICALLY PADDED WITH A SELECTED NUMBER OF EMPTY SEGMENTS. ANOTHER FEATURE IS FLEXIBLE—CAPACITY SCALING, WHICH DISTRIBUTES AN ORDERED SET OF DEVICE BLOCKS ON A MULTI—TRACK MAGNETIC TAPE MEDIUM. THE DEVICE BLOCKS ARE BI—DIRECTIONALLY STORED IN A CONTINUOUS CONFIGURATION OF MULTIPLE ADJACENT STACKED SERPENTINE PALTERNS OCCUPYING SOME OR ALL OF THE TAPE. THIS CONFIGURATION PERMITS SEQUENTIAL ACCESS OF ALL DEVICE BLOCKS WITHOUT ADVANCING THE TAPE MEDIUM TO SKIP OVER REGIONS BETWEEN ADJACENT DEVICE BLOCKS. (FIG. 2 )

Abstract: Data storage drives of an automated data storage library are allocated to received requests. A drive resource provider (35), upon receiving a request for a drive when all of the drives of the pool are allocated, holds any mount of a portable data storage cartridge relative to the request, releasing the hold when a drive is allocated. Spare drives are provided, outside of the pool. A spare drive may be allocated in response to the request, and a message is posted indicating use of the spare data storage drive. The posted message may comprise a notification that action may be taken to permanently transfer a spare data storage drive to the pool. Furthermore drive image providers of a virtualization system for an automated data storage library provide an image of a fixed plurality of virtual data storage drives with fixed identifications to a host application. A drive resource provider (35), at any one time, assigns any number "m" of a pool of "n" drives to the drive image providers, and "n" - "m" of the pool are freed and available for assignment. The drive resource provider (35) responds to a triggering event requesting a drive, and dedicates one of the "n" - "m" drives of the pool to the virtual drive. The drive image provider (30) characterizes and directs communication between the host and the dedicated drive as a fixed virtual drive; and prior to the dedication of a drive, characterizes the virtual drive to the requesting host application as "not ready".

Abstract: various data storage formats help to efficiently locate, read, and write user data stored on magnetic tape media. A tape is formatted by writing multiple segment-headers, free from any interleaved access of user data. Adjacent segment-headers are spaced by a predetermined interval to define multiple data storage segments. Segment-headers all contain a unique key, which is copied into a key index to identify valid segments. After formatting, normal tape accesses can be performed. Without erasing any old headers or data, a new formatting scheme can be established by writing new segment-headers on the tape. The new segment-headers include a new unique key, replacing the previous key in the key index. Previous segment-headers stored on the tape are ignored, since they lack the updated key. Segments may be selectively grouped to provide independently addressable partitions. Mapping between segments and partitions can use a fixed relationship (e.g. one-to-one), or each partition may be variably sized according to the amount of data to be stored therein. Variable-sized partitions may be automatically padded with a selected number of empty segments. Another feature is flexible-capacity scaling, which distributes an ordered set of device blocks on a multi-track magnetic tape medium. The device blocks are bi-directionally stored in a continuous configuration of multiple adjacent stacked serpentine patterns occupying some or all of the tape. This configuration permits sequential access of all device blocks without advancing the tape medium to skip over regions between adjacent device blocks.
