ATCA-S201 Overview

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.

1.1Features 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
