Technical Product Specification

Intel® Server System P4000IP and Intel® Workstation System P4000CR Family TPS Storage and Peripheral Drive Bays
94 Intel order number G38159-002 Revision 1.2
4.3.1 Protocol Support
Each port on the expander cards support SAS devices, SATA II devices, or both using SSP,
SMP, STP, and SATA II as follows:
 Serial SCSI Protocol (SSP) to enable communication with other SAS devices.
 SATA II Protocol to enable communication with other SATA II devices.
 Serial Management Protocol (SMP) to share topology management information with
expanders.
 Serial Tunneling Protocol (STP) support for SATA II through expander interfaces.
 SAS protocol, described in the Serial Attached SCSI (SAS) Standard, version 2.0
 SFF-8485 protocol, using the Serial GPIO (SGPIO) interface provided by the expander.
4.3.2 SAS Expander Features
 Supports both Serial Attached SCSI and Serial ATA devices
 6.0 Gbit/s, 3.0 Gbit/s, and 1.5 Gbit/s data transfer rate
 SFF-8087 mini-SAS connectors
 Output mini-SAS connectors support sideband SGPIO as per SFF-8485 specification
 Provides a low-latency connection to create and maintain transparent access to each
connected SAS/SATA physical drive
 Staggered spin-up
 Hot Plug
 Native Command Queuing
 Allows multiple initiators to address a single target (in a fail-over configuration)
4.4 Optical Drive Support
The Intel
®
Server System P4000CP includes support three 5.25'' optical drive bays. The optical
drives can be installed to one of the three drive bays as illustrated below. The data cable from
