1 ATCA-S201 Overview
The Emerson ATCA-S201 is an ATCA carrier blade that supplies multi-protocol IP storage
services to the chassis Zone-2 backplane using Ethernet connections. The ATCA-S201
virtualizes capacity of AMC SAS/SATA disks and creates multiple logical volumes which are
mapped as iSCSI, NFS or SMB targets. Using access control lists, ATCA server blades are
given authorization to connect with virtualized volumes via 10 GbE fabric or 1GbE base
connections.
The ATCA-S201 carrier can accommodate up to four AMC disk modules. Additional disks
may be added using an Advanced ARTM which adheres to the Advanced RTM zone-3
connector pin out.
Users may also deploy the ATCA-S201 to realize gateway functions with external equipment
including SAS and/or Fiber channel (FC) storage area networks (SANs). For example,
populate with an AMC 4 Gb FC controller modules, and establish gateway services between
LUN volumes in the FC data center and the ATCA GbE network.
1.1 Features of the ATCA Storage Module
The ATCA-S201 is single slot carrier board for ATCA shelves. Measuring 8U (280mm)
x 325 mm, the carrier includes four advanced mezzanine card (AMC) slots for
storage disks or SAN connections. Several on board Ethernet controllers provide
connections to the base and fabric interfaces.
The prominent digital components include:
Freescale® 1.3Ghz, super scalar PowerPC processor
Intel® dual port 10 GbE Ethernet controller
LSI® 8 port SAS controller, with RAID
PLX® 48 Lane PCI Express Switch
1GB SODIMM, 533MHz DDR2, with ECC (72b)
Carrier IPMC, with hot swap and LED control
FRUID serial EERPORM (note: The FRU ID is not a separate part but rather
embedded in the MMC controller.)
Temperature sensors
Voltage sensors
SPI flash memory
The ATCA-S201 is loaded with software which enables it to terminate several IP
protocols, and efficiently map these protocols to block I/O storage using SAS/SATA
disks, and optional RAID protection. This product can also map IP protocols to Fibre
Channel SAN resources, if populated with a 4Gb Fibre channel AMC module.
Key software services include:
iSCSI service (IETF RFC-3720)
NFS service version 3 (network file share)
SMB service (Server Message Block file system)
Integrated RAID0, RAID1 and RAID1E service
SNMP
HTML web configuration client
