[. . . ] (Refer to Figure 3 on next page. ) Click the Configuration tab in the dialog box and increase the Media block size (Kb) from the default setting of 32 Kb. Ensure your operating system and drive can support the new value entered. Click the Performance tab in the dialog box and increase the default transfer memory buffer setting from the default setting of 257 Kb. Ensure your operating system can support the new value entered. NOTE: The Amount of memory to assign to transfer buffers (Kb) is what is often referred to as the shared memory setting. The shared memory is allocated in 32Kb blocks, with one byte added. The optimum figure is dependent on the drive model, and will be stated in the relevant BakBone Software Benchmark document, but the minimum value to use is at least 4x the block size setting for the drive. Ensure there is sufficient RAM (Windows NT or 2000) or Kernel Memory (UNIX). If there are more drives repeat the above steps for each drive as required. Save device configuration by selecting the "Save Details" button in the top left corner. Select OK for the "Device added successfully" window. Close the "Add Library" window.

Drive Performance Tuning BakBone Software, Inc. 6 11/2/2004 Device Application Notes For NetVault Revision A7 Other information Known Firmware Issues: None. Device Notes: When importing/exporting tapes through the front door, once complete, you must exit (cancel) all the way out of the front panel menus for the loader to re-inventory and return to an ONLINE state. Otherwise, when issuing the "close door" operation in NetVault, the loader will remain OFFLINE according to NetVault. For optimal performance, Certance recommends a block size of 64Kb and a shared memory setting of 64Mb (65536 Kb). Note your operating system must be able to support this when configured. The LTO Ultrium capacity specification (re)defines 1 Gb as 1, 000, 000, 000 bytes instead of the standard 1024 x 1024 x 1024 bytes (1, 073, 741, 824 bytes). [. . . ] Import cleaning cartridge(s) into CLEANING SLOT(s) and/or import cleaning cartridge(s) with configured barcode prefixes. Ensure Generic Cleaning tape support is enabled for the drive. To ensure this setting is enabled, in Device Management, while the drive is idle, right-click on the drive and select Configure. On the Configuration tab, ensure the option "Cleaning Tapes Supported" is checked and if not, check it. [. . . ]
