QXS 4-Series Chassis Overview

The following applies to Xcellis Workflow Director (R630), aiWARE for Xcellis Embedded (DAE)systems.

QXS 2U drive chassis provide include a bezel sub-assembly that attaches to the front panel of the chassis. The bezel, comprised of a vented cover attached to an electro-magnetic interference (EMI) shield, is pre-assembled and packed within a box contained in the chassis master shipping container. The bezel might include a removable air filter that can be serviced or replaced. Instructions for attaching/removing the bezel, and for servicing or replacing the air filter, are provided in the QXS Bezel Installation Guide.

Caution: Whether configured with or without an air filter, to ensure adequate EMI protection for the drives, the bezel should be properly installed while the chassis is in operation.

Caution: Drive blanks (air management modules) must be installed within a 24 Drive Chassis in the unpopulated drive slots to ensure system cooling and air flow.

The diagram and table below display and identify important component items that comprise the rear panel layout of a QXS RAID Chassis. The following image shows a representative example of RAID chassis models included in the product series.

2. Controller Module A

3. Controller Module B

A RAID chassis accommodates two AC power supplies (CRU) within the two power supply slots (Callout 1 above). RAID Chassis accommodate two controller modules (CRU) of the same type within the Controller I/O Module slots (Callouts 2 and 3 above).

Caution: All QXS configurations are dual-controller. Single-controller support is provided only when a controller fails over to its partner controller. A controller module must be installed in each Controller I/O Module slot to ensure sufficient airflow through the chassis during operation.

The I/O Controller Module has two model types, converged network controller (CNC) ports or mini-SAS HD. The models can be configured as follows:

  • Host CNC ports configured with SFPs supporting the following:
    • 4/8/16 Gb FC
    • 10GbE iSCSI
  • Host interface ports configured with 12 Gbit/s mini-SAS HD (SFF-8644) connectors.

The following figure shows CNC ports configured with SFP+ transceivers that support 4, 8, or 16 Gb FC, or 10 GbE iSCSI connections. The SFPs look identical. Refer to the CNC LEDs that apply to the specific configuration of your CNC ports.

8. Mini-SAS Expansion Port

12 drive Expansion Chassis support 12 x 3.5" Large Form Factor (LFF) drives for expansion of storage capacity. The 24 drive Expansion Chassis support 24x2.5" Small Form Factor (SFF) drives for expansion of storage capacity. These chassis use mini-SAS (SFF-8088) connectors to facilitate attachment to the RAID Chassis and allow for additional backend SAS expansion attachment(s).

Note: Refer to the Release Notes for the number of drives and Expansion Chassis supported with each RAID Chassis.
