參看圖6,其說明圖1、圖2、圖3及圖4之磁帶匣100的匣式記憶體104之內容的一實例。匣式記憶體104及其內容之一實例係描述於標準ECMA-319,2001年6月,"Data Interchange on 12,7 mm 384-Track Magnetic Tape Cartridges-Ultrium-1 Format",附錄D-LTO匣式記憶體,第95頁至115頁中。作為一實例,匣式記憶體104係配置於具有組織成"頁"之資訊之各種大小的區域中。匣式記憶體104可類似於如熟習此項技術者所已知之"智慧卡"中所用的記憶體及轉發器。熟習此項技術者可預見額外類型之匣式記憶體。Referring to Figure 6, an example of the contents of the cartridge memory 104 of the tape cartridge 100 of Figures 1, 2, 3 and 4 is illustrated. An example of the 匣-type memory 104 and its contents is described in the standard ECMA-319, June 2001, "Data Interchange on 12, 7 mm 384-Track Magnetic Tape Cartridges-Ultrium-1 Format", Appendix D-LTO匣Memory, pages 95 to 115. As an example, the 记忆-type memory 104 is arranged in regions of various sizes having information organized into "pages". The memory 104 can be similar to the memory and transponders used in "smart cards" as is known to those skilled in the art. An additional type of 记忆 memory can be foreseen by those skilled in the art.
記憶體系統130之記憶體131可(如圖6中所說明)經格式化以包括一標頭150及各種資訊區域151、152。標頭150將併入有關於資訊區域及關於資訊之使用的資訊,且可併入有特定識別及安全性資訊。The memory 131 of the memory system 130 can be formatted (as illustrated in FIG. 6) to include a header 150 and various information regions 151, 152. The header 150 will incorporate information about the information area and use of the information, and may incorporate specific identification and security information.
根據本發明之一實施例,記憶體系統130經格式化以允許與資料儲存媒體之複數個分割區127A、127B、127C等中的至少一者相關聯。舉例而言,匣式記憶體104C之記憶體系統的資訊區域151可與圖5之分割區127C相關聯。In accordance with an embodiment of the present invention, memory system 130 is formatted to allow association with at least one of a plurality of partitions 127A, 127B, 127C, etc. of a material storage medium. For example, the information area 151 of the memory system of the memory 104C can be associated with the partition 127C of FIG.
以此方式,圖1、2、3及4之磁帶匣100的匣式記憶體104A、104B、104C、104D及104E中每一者可與圖5之資料儲存媒體的一不同分割區127A、127B、127C等相關聯。該關聯可意味著,儲存區域中含有關於相關聯分割區之資料的資訊。此外,該關聯可包括儲存區域中所含有的允許藉由資料儲存驅動機或主機對分割區進行管理之資訊,該資訊包含資料之安全性及處理。In this manner, each of the cartridge memories 104A, 104B, 104C, 104D, and 104E of the cartridge 100 of Figures 1, 2, 3, and 4 can be combined with a different partition 127A, 127B of the data storage medium of FIG. 127C and other related. This association may mean that the storage area contains information about the information of the associated partition. In addition, the association may include information contained in the storage area that allows the partition to be managed by the data storage drive or the host, the information including the security and processing of the data.
另外,每一邏輯分割區可具有其自身之實體擁有者,例如,資料儲存驅動機或主機之使用者。因此,實體資料儲存媒體或匣可存在多個擁有者,每一擁有者在併入有獨立匣式記憶體104A、104B、104C、104D及104E之資訊的管理之下。In addition, each logical partition may have its own physical owner, such as a data storage drive or a user of the host. Thus, a physical data storage medium or magazine may have multiple owners, each under the management of information incorporating independent cartridge memories 104A, 104B, 104C, 104D, and 104E.
在多個匣式記憶體服務多個分割區的情況下,對帶匣之存取被虛擬化且匣可與附著有資料儲存裝置之儲存區域網路(SAN)介面相接合。In the case where multiple ports of memory serve multiple partitions, the access to the tape is virtualized and can be interfaced with a storage area network (SAN) interface to which the data storage device is attached.
在另一實施例中,匣式記憶體104A、104B、104C、104D及104E中每一者為可獨立定址的。In another embodiment, each of the cartridge memories 104A, 104B, 104C, 104D, and 104E is independently addressable.
在一實施例中,匣式記憶體中每一者之通信介面包括一以不同頻率操作之射頻介面。舉例而言,圖4之通信介面126包括電路135,該等電路包括一感應天線環路及電容器,其中該等電容器具有不同電容以提供不同頻率。不同頻率將交替地允許藉由以所有頻率進行之通信對匣式記憶體中一個以上或所有匣的同時存取,或允許以一特殊頻率對僅一匣式記憶體之存取。In one embodiment, the communication interface of each of the cartridge memories includes a radio frequency interface that operates at a different frequency. For example, communication interface 126 of FIG. 4 includes circuitry 135 that includes an inductive antenna loop and capacitors, wherein the capacitors have different capacitances to provide different frequencies. Different frequencies will alternately allow simultaneous access to more than one or all of the ports in the memory by communication at all frequencies, or access to only one bank of memory at a particular frequency.
或者,匣式記憶體中每一者之通信介面126包括一可獨立定址之數位介面。舉例而言,每一匣式記憶體可具有其自身之唯一識別符。藉由需要將識別符嵌入於輸入/輸出(I/O)指令中(用於寫入至匣式記憶體及自匣式記憶體讀取),可實現至個別匣式記憶體之讀取及寫入。Alternatively, each of the communication interfaces 126 of the cartridge memory includes an addressable interface that is independently addressable. For example, each type of memory can have its own unique identifier. By inserting an identifier into an input/output (I/O) command (for writing to a 记忆-type memory and a self-following memory), reading to an individual 记忆 memory can be achieved. Write.
在另一實施例中,匣式記憶體中每一者包括提供一獨立密碼以獲得對記憶體系統之讀取及/或寫入存取。可將密碼儲存於圖6之非揮發性記憶體131的標頭150中。術語"密碼"係用以指任何合適之鑑認演算法以允許對匣式記憶體及/或相關聯分割區之資訊的使用者存取。In another embodiment, each of the cartridges includes providing a separate password to obtain read and/or write access to the memory system. The password can be stored in the header 150 of the non-volatile memory 131 of FIG. The term "password" is used to refer to any suitable authentication algorithm to allow user access to information about the memory and/or associated partitions.
在另一實施例中,匣式記憶體中每一者之記憶體系統經組態以格式化資訊從而允許與資料儲存媒體之複數個分割區127A、127B、127C等中的一子組分割區相關聯。舉例而言,匣式記憶體104C之記憶體系統的資訊區域151可與圖5之分割區127B及127C相關聯。In another embodiment, the memory system of each of the cartridge memories is configured to format information to permit a subset of the plurality of partitions 127A, 127B, 127C, etc. of the data storage medium. Associated. For example, the information area 151 of the memory system of the memory 104C can be associated with the partitions 127B and 127C of FIG.
在又一實施例中,匣式記憶體中至少一者之記憶體系統經組態以格式化資訊從而允許匣式記憶體中另一者之資訊的至少一部分之間的冗餘。舉例而言,匣式記憶體104C之記憶體系統的資訊區域151可與分割區127B相關聯,且資訊區域152可重複資訊區域或匣式記憶體104B之標頭的至少一部分。此外,可在標頭150或資訊區域151中提供錯誤後移轉資訊(failover information)以致匣式記憶體中之一者的故障將引起另一匣式記憶體中之冗餘資訊的錯誤後移轉且因此不會引起匣之故障。處理器137可具有必要之演算法以使得錯誤後移轉對於使用者為透明的,及/或向使用者或管理者提供一錯誤旗標或訊息。In yet another embodiment, at least one of the memory systems of the cartridge memory is configured to format information to permit redundancy between at least a portion of the information of the other of the cartridges. For example, the information area 151 of the memory system of the memory 104C can be associated with the partition 127B, and the information area 152 can repeat at least a portion of the header of the information area or the memory 104B. In addition, error post-failover information may be provided in header 150 or information area 151 such that failure of one of the 匣-type memories will cause erroneous back-shifting of redundant information in another 记忆-type memory And therefore does not cause a malfunction. Processor 137 may have the necessary algorithms to make the post-error transfer transparent to the user and/or provide an error flag or message to the user or manager.
參看圖1,根據本發明之一實施例,匣式記憶體104A、104B、104C、104D及104E中每一者係藉由容器101而支撐,該容器101經定位以致通信介面可(例如)藉由圖3之資料儲存驅動機115的介面117在資料儲存匣100之外部而同時存取。參看圖4,在一實施例中,匣式記憶體係藉由容器支撐以致匣中每一者之天線135以類似方向定向從而允許同時存取。在實例中,匣式記憶體中每一者以關於圖1之容器100的底部及側面大體成45°角而定向,以便允許藉由資料儲存驅動機或藉由自動資料資料庫之撿出器對所有匣式記憶體進行同時存取,該等匣式記憶體關於匣成相對不同之角。Referring to FIG. 1, in accordance with an embodiment of the present invention, each of the cartridge memories 104A, 104B, 104C, 104D, and 104E is supported by a container 101 that is positioned such that the communication interface can, for example, be borrowed The interface 117 of the data storage drive 115 of FIG. 3 is simultaneously accessed outside the data storage port 100. Referring to Figure 4, in one embodiment, the jaw memory system is supported by the container such that the antennas 135 of each of the cassettes are oriented in a similar direction to allow simultaneous access. In an example, each of the cartridge memories is oriented at a substantially 45° angle with respect to the bottom and sides of the container 100 of FIG. 1 to allow for a data storage drive or an extractor via an automated data repository. Simultaneous access to all of the 记忆-type memories, which are relatively different angles.
參看圖3及圖7,根據本發明,(例如)資料儲存驅動機115之控制系統124提供將資料儲存匣100之資料儲存媒體105的容量部分分配至資料儲存匣之匣式記憶體104A、104B、104C、104D及104E中之多者的服務;並將界定已分配部分之資訊提供至匣式記憶體中已分配有容量的匣式記憶體。術語"匣式記憶體中之多者"係指將容量獨立地分配至複數個匣式記憶體中每一者,直至且包含所有匣式記憶體為止。Referring to Figures 3 and 7, in accordance with the present invention, control system 124 of, for example, data storage drive 115 provides for the allocation of the portion of the data storage medium 105 of data storage 100 to the storage memory 104A, 104B. The services of the plurality of 104C, 104D and 104E; and the information defining the allocated portion is provided to the 匣 type memory of the 记忆 type memory that has been allocated capacity. The term "many of the 匣 memory" means that the capacity is independently allocated to each of the plurality of 记忆-type memories up to and including all 匣-type memories.
在一實施例中,對每一使用者之匣式記憶體104A、104B、104C、104D及104E給出容量限制。若使用者需要額外容量,則(例如)請求額外容量或可分配或購買額外容量。In one embodiment, a capacity limit is given for each user's jaw memory 104A, 104B, 104C, 104D, and 104E. If the user requires additional capacity, for example, request additional capacity or allocate or purchase additional capacity.
在圖7所說明之一實施例中,由於讀取操作係關於先前存在之容量,故將容量分配於寫入操作上。自步驟202開始,步驟204確定使用者是否請求寫入操作。使用者可包括具有對資料儲存驅動機及對資料儲存媒體之存取的系統、個體或實體或任何組合。若步驟204確定存取不同於寫入操作(例如為讀取操作),則對於另一過程授與存取。舉例而言,存取可對於讀取操作而言,且在步驟206中,存取用於請求使用者之匣式記憶體以確定所要資料之媒體上的位置,且在步驟208中,進行另一操作。In one embodiment illustrated in Figure 7, the capacity is allocated to the write operation since the read operation is with respect to the previously existing capacity. Beginning at step 202, step 204 determines if the user requests a write operation. The user may include a system, entity or entity or any combination of access to the data storage drive and to the data storage medium. If step 204 determines that the access is different from the write operation (e.g., a read operation), then access is granted for another process. For example, the access may be for a read operation, and in step 206, accessing the user's memory to determine the location on the media of the desired material, and in step 208, performing another An operation.
若步驟204確定使用者請求寫入操作,則步驟210存取指派給使用者之匣式記憶體以確定分配至匣式記憶體及分配至使用者的當前容量。若未指派匣式記憶體給使用者,則可配置彼指派。If step 204 determines that the user requests a write operation, then step 210 accesses the scratch memory assigned to the user to determine the current capacity allocated to the memory and assigned to the user. If the memory is not assigned to the user, then the assignment can be configured.
可使用以下兩個方式中之一者提供分配至使用者之匣式記憶體104A、104B、104C、104D及104E的容量:可分配於資料儲存媒體中任何處之邏輯分割區;或可為作為實體獨立之區域的實體分割區,諸如一群平行磁軌,如以上所界定的。The capacity of the ports of memory 104A, 104B, 104C, 104D, and 104E assigned to the user may be provided in one of two ways: a logical partition that may be allocated anywhere in the data storage medium; or may serve as An entity partition of an entity-independent area, such as a group of parallel tracks, as defined above.
步驟212確定是否將足夠容量分配至匣式記憶體及使用者以用於所要寫入操作,或替代地,用於所要總容量分配。若已進行足夠容量分配,且分配為邏輯容量,則可在步驟214中獲得分割區之特定位置。步驟214存取所有匣式記憶體以找出資料儲存媒體之自由空間位置,並識別用於使用者之寫入操作或請求的特定位置。或者,分配可包括容量之一或多個實體部分,且匣式記憶體中繼資料(metadata)描述實體分割區且步驟214確定預先存在之實體分割區內的自由空間位置。在步驟216中,由使用者進行寫入操作,且以已儲存資料之位置的中繼資料來更新使用者之匣式記憶體。Step 212 determines if sufficient capacity is allocated to the cartridge and user for the desired write operation or, alternatively, for the desired total capacity allocation. If sufficient capacity allocation has been made and assigned as logical capacity, a particular location of the partition may be obtained in step 214. Step 214 accesses all of the memory to find the free space location of the data storage medium and identify the particular location for the user's write operation or request. Alternatively, the allocation may include one or more physical portions of the capacity, and the meta-memory relay metadata describes the physical partition and step 214 determines the free-space location within the pre-existing entity partition. In step 216, the user performs a write operation and updates the user's memory with the relay data of the location where the data has been stored.
若步驟212指示無足夠容量分配至匣式記憶體及使用者以用於所要請求(例如,用於寫入操作),或替代地,無經配置用於所請求總容量分配之足夠容量,則步驟220確定資料儲存媒體是否具有可用以滿足請求之足夠剩餘容量。若無足夠之剩餘容量可用於資料儲存媒體105中,則過程在步驟224中異常終止。If step 212 indicates that there is not enough capacity allocated to the memory and the user for the requested request (eg, for a write operation), or alternatively, there is no sufficient capacity configured for the requested total capacity allocation, then Step 220 determines if the data storage medium has sufficient remaining capacity available to satisfy the request. If there is not enough remaining capacity available in the data storage medium 105, the process terminates abnormally in step 224.
若步驟220確定資料儲存媒體105中存在足夠剩餘容量以滿足請求,則步驟222將資料儲存匣之資料儲存媒體之容量部分分配至匣式記憶體中的一者以滿足請求。已分配容量部分可包括一或多個邏輯分割區或一或多個實體分割區。在步驟222中,以界定已分配容量部分之資訊來更新使用者之匣中繼資料。在步驟216中,由使用者進行寫入操作,且以所儲存資料之位置的中繼資料來更新使用者之匣式記憶體。If step 220 determines that there is sufficient remaining capacity in the data storage medium 105 to satisfy the request, then step 222 assigns the capacity portion of the data storage medium of the data storage to one of the cartridges to satisfy the request. The allocated capacity portion may include one or more logical partitions or one or more physical partitions. In step 222, the user's relay data is updated with information defining the allocated capacity portion. In step 216, the user performs a write operation and updates the user's memory with the relay data of the location of the stored data.
