This appendix provides information about the tape drives and the media used in the SL500 Modular Library. Refer to the vendor publications and websites for specific information not covered in this publication.
The library can hold up to 18 tape drives. The library supports:
Linear Tape-Open (LTO) Ultrium tape drives:
Hewlett-Packard LTO Generation 2, 3, 4, 5, and 6
IBM LTO Generation 2, 3, 4, and 5
Quantum Super Digital Linear Tape (SDLT) tape drives:
SDLT 320
SDLT 600
DLT-S4
The interfaces supported for these tape drives include:
Small computer system interface (SCSI)
Fibre Channel (FC) interface
Serial attached SCSI (SAS)
This section discusses media compatibility and cartridge labels. For best results, match the cartridge type with the drive type. Refer to the Barcode Technical Brief on OTN for information on cartridge labels.
LTO tape drives are:
Read compatible backward two generations
Write compatible backward one generation

Cartridges are not shipped as part of the SL500 Modular Library System; they must be ordered separately before the installation.
Contact your authorized selling agent for approved labeled cartridges.
Call 1.877.STK.TAPE to order media from your local reseller or to obtain media pre-sales support.
See the tape media area on the corporate website for additional information:
http://www.oracle.com/us/products/servers-storage/storage/tape-storage/overview/index.html
The customers can use their existing cartridges if they are compatible with the supported tape drives and are still within their warranty period. Oracle Professional Services offer transition support and services to help migrate media and drives.
Contact your authorized Oracle sales representative for Oracle-branded labeled cartridges. You do not need to order labels separately, because the data cartridges have labels already, and the cleaning and diagnostic labels are shipped with the installation hardware. However, you must select the VOLSER range and other label options when ordering cartridges.
If you choose to order additional labels, order them from any standard media vendor. Cartridges must meet specifications defined in American National Standard Magnetic Tape and Cartridge for Information Interchange, ACS X3B5. Refer to your tape drive manufacturer's publication and website for specific cartridge requirements and specifications.
Color cartridges are approved only if the measured reflection density is greater than 0.1 as measured by an X-rite 404G color reflection densitometer. For more information about colored cartridges, contact your marketing representative.
Color measurements are:
| Bandwidth | ANSI Status T Wide band (380 to 780 nm) |
| Measuring range | Density (0.00 to 2.50) D |
| Accuracy | ±0.02 D |
| Repeatability | ±0.01 D |
| Aperture diameter | 3.4 mm (0.13 in.) |
