SmartEdge Storage Engine
8 SmartEdge Storage Engine
The SmartEdge Storage Engine (SSE) card is an internal services card
designed to provide fault-tolerant file storage services for clients and various
applications internal to the SmartEdge 600, SmartEdge1200, or SmartEdge
1200H router. This highly available services card provides Network File System
(NFS) services to store large amounts of data.
The SSE card supports up to two SCSI Attached Storage (SAS) hard disk
drives (HDD) with an onboard SAS controller, Network Processor (NP),
Packet Mesh ASIC (PMA), and other components. This card operates with
the XCRP4 Controller cards and in any I/O card slot in the SmartEdge 600,
SmartEdge1200, or SmartEdge 1200H router.
8.1 Hard Disk Drive Description
The SSE card houses one or two standard SAS 2.5” drives, which are
hot-swappable field-replaceable units that can be mounted in a HDD slot on the
SSE without removing the card. You can insert and remove an HDD without
affecting the operation of the other HDD. These HDDs are separate devices
and can be used to perform Redundant Array of Independent Disks (RAID1)
redundancy to provide a highly fault tolerant system.
The HDDs have a storage capacity of 300 GB and are controlled by CLI
commands received from the Network Processor (NP) through the SAS
controller.
The SAS controller is used by the NP to communicate to the SAS drives. The
controller handles all HDD communications and start-up procedures.
