1211 Drive Bay Options

CS500 model 1211 drive bay options and LED status.

The CS500 model 1211 server drive bays vary depending on the server model and available accessory options installed.
  • 2.5in drives
    • 8x SATA/SAS/NVMe
    • 24x SATA/SAS/NVMe
  • 3.5in drives
    • 8x SATA/SAS
    • 12x SATA/SAS/up to 2 NVMe

Drive Numbering

Drive numbers in the following two figures typical numbering schemes. However, actual drive numbering depends on SAS/SATA controller configuration and backplane cabling. Drive backplanes use multi-port, mini-SAS HD connectors for each set of four SATA/SAS drives. Backplanes that support NVMe drives also include a single PCIe OCuLink connector for each supported NVMe drive.

Drive Statues LEDs

Drive trays for both 2.5in and 3.5in drives include separate amber and green LED indicators. Light pipes in the trays direct light from LEDs on the backplane to the front of the drive tray, making them visible from the front of the chassis.

The drive activity LED is driven by signals coming from the drive itself. Drive vendors may choose to operate the activity LED differently from what is described in the table below. Should the activity LED on a given drive type behave differently than what is described, customers should reference the drive vendor specifications for the specific drive model to determine the expected drive activity LED operation.
