MX240 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 30 on page 86) 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.
