IBM 39M0489 Ultra320 SCSI cable assembly with three drop connectors for daisy-chaining multiple devices in high-performance storage environments. Supports up to 320 MB/s data transfer rates across Ultra320 SCSI bus architecture, compatible with IBM storage subsystems, disk arrays, and legacy server configurations requiring external SCSI connectivity. The 3-drop design enables connection of multiple tape drives, disk arrays, or mixed storage peripherals from a single initiator port. Ideal for legacy SAN migration projects, archival system upgrades, and environments consolidating older SCSI-based storage infrastructure. Typical applications include IBM TotalStorage systems, high-capacity tape libraries, and external RAID arrays operating in enterprise data centers.Tested and guaranteed. Available via quote.
