MX960 Application Services Modular Storage Card Description

Application Services Modular Storage Card (AS MSC) is a NAND Flash-based card that is inserted into the upper slot of the Application Services Modular Line Card (AS MLC). The AS MSC (see Figure 1) serves as the second tier caching storage for platforms such as the Junos Content Encore system. This card is equivalent to a PIC or a Modular Interface Card (MIC) and provides a maximum of 3.6 Gbps read and 2 Gbps of write memory.

The AS MSC has the following features:

  • 400 GB NAND Flash memory

  • Up to 10 years of write memory

  • Multilevel cell (MLC) NAND memory support

  • Best-in-class NAND controller for maximum performance and reliability

AS MSCs are hot-removable and hot-insertable. One AS MSC can be installed in the top slot of each AS MLC. Each AS MSC has these components:

  • SATA-3 controller—An eight-ports, 6 Gbps SAS/SATA controller.

  • NAND Flash controller— NAND Flash and NAND Flash controller are used in an AS MSC.

  • Control plane—Inter-integrated circuit control plane that allows Peripheral Component Interconnect Express (PCIe) control.

  • LEDs—Two LEDs display the status of the AS MSC and storage.

  • Online/offline button—To power on or power off the AS MSC.
