MX480 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
) 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 48K of write cycle
•
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-port, 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.
