1-2 Netra CP32x0 SAS Storage Advanced Rear Transition Module HD User’s Guide • January 2009
1.1 Features of the ARTM-HD
The Netra CP32x0 SAS Storage Advanced Rear Transition Module HD (ARTM-HD)
is a fully compatible, carrier-grade Advanced Telecom Computing Architecture
®
(ATCA) ARTM for ATCA blade servers designed to be compatible with the
AdvancedRTM specification. The ARTM-HD is not compatible with ATCA cards
that do not comply with this specification.
The 6 rack unit (6U) form factor, single-slot ARTM supplies either single or dual SAS
hard disk drives, and rear I/O connections that support additional peripherals for
use with compatible Netra ATCA blade servers. The rear I/O access enables you to
replace the Netra ATCA blade servers without disconnecting cables.
Industry-standard connectors and pin assignments ensure ease of use and flexible
design. The ARTM-HD permits the creation of high-density systems by enabling
easy access to I/O (
FIGURE 1-1).
Features of the ARTM-HD include:
■ Conforms to ARTM Interface specification
■ Conforms to PICMG ATCA card specification for RTM cards
■ RTM is hot-swappable to its blade server
■ Either single or dual hot-swappable 146 GB SAS hard disk drive (HD)
■ One LSI1068E PCIe to 8-Port SAS controller, flash device, and NVSRAM to
support boot code and RAID support
■ Infinband-style connectors for external drive support using a type SFF-8470 SAS
cable
■ Supports primary and secondary external connections
■ PCIe x8 bus interface to blade server
■ One asynchronous serial port to RJ45 connector
■ One 10/100/1000 MBASE-T management port, with LEDS
■ Vitesse VSC410 MMC
■ 25W Max power
■ NEBS level 3 compliant
The ARTM-HD requires an ATCA shelf (chassis) with a midplane that
accommodates front and rear blade server installations. The primary purpose of this
module is to provide a single or dual SAS drive and rear access connections to the
blade server’s I/O devices.
