12 meters long. Throughput on each SCSI channel can be as high as 320 Mbytes/s. You can install the MegaRAID 320 storage adapters in PCI-X computer systems with a standard bracket type. With these adapters in your PCI or PCI-X system, you can connect SCSI devices over a SCSI bus.
MegaRAID 320-2 supports up to 256 Mbytes of SDRAM; a 32-, 64-, 128-, or 256-Mbyte DIMM can be installed. MegaRAID 320-2X and -4X support up to 1 Gbyte of double data rate (DDR) SDRAM; a 32-, 64-, 128-, 256, or 512-Mbyte, or 1-Gbyte DIMM can be installed.
Battery backup for up to 72 hours for the MegaRAID 320-2, -2X, and Support for up to 14 SCSI drives per channel on storage system with SAF-TE enclosures (SCSI accessed fault-tolerant enclosures): 15 SCSI drives per channel for other configurations 32 Kbyte x 8 NVRAM for storing RAID system configuration...
Configuration on Disk Configuration on Disk saves configuration information both in NVRAM on the MegaRAID 320 storage adapter and on the disk drives attached to the storage adapter. If the storage adapter is replaced, the new storage adapter detects the actual RAID configuration from the configuration information on the drives.
Step 3. Determine the SCSI ID and SCSI termination requirements. Step 4. Install the MegaRAID 320 storage adapter in the server, connect SCSI devices to it, and set termination correctly on the SCSI channel(s). Ensure that the SCSI cables you use conform to all SCSI specifications.

Each device in a channel must have a unique TID. Provide unique TIDs for non-disk devices (CD-ROM or tapes), regardless of the channel where they are connected.
The firmware takes several seconds to initialize. During this time, the storage adapter scans the SCSI channel(s). The MegaRAID 320 BIOS Configuration utility prompt times out after several seconds. The second portion of the BIOS message displays the MegaRAID 320 storage adapter number, firmware version, and cache SDRAM size.
PCI Local Bus Specification, Revision 2.2, and PCI- X Addendum to the PCI Local Bus Specification, Revision 1.0a. The MegaRAID 320 storage adapters are used in PCI-X and PCI computer systems with PCI standard and PCI low-profile bracket types.
3.1.1 Single-Channel Storage Adapter The MegaRAID 320-1 is a single-channel Ultra320 SCSI-to-PCI storage adapter that supports one Ultra320 SCSI channel. The MegaRAID 320-1 SCSI channel interface is made through connectors J1 and J7. See Figure 3.1 Table 3.1 for information about the important connectors and headers on the MegaRAID 320-1 storage adapter.
Ultra320 SCSI channels. Figure 3.2 Table 3.2 for information about the important connectors and headers on the MegaRAID 320-2 storage adapter. See Figure 3.3 Table 3.3 for information about the important connectors and headers on the MegaRAID 320-2X storage adapter.
3.1.3 Quad-Channel Storage Adapter The LSI Logic MegaRAID 320-4X is a quad-channel Ultra320 SCSI-to- PCI-X storage adapter that supports four Ultra320 SCSI Channels. See Figure 3.4 Table 3.4 for information about the important connectors and headers on the MegaRAID 320-4X storage adapter.
Fusion-MPT architecture that allows for thinner drivers and better performance. Technical Specifications The design and implementation of the MegaRAID 320 storage adapters minimizes electromagnetic emissions, susceptibility to radio frequency energy, and the effects of electrostatic discharge. The storage adapters carry the CE mark, C-Tick mark, FCC Self-Certification logo, Canadian...
SMART also monitors the internal performance of all motors, heads, and drive electronics. 3.3.4 Electrical Characteristics This section provides the power requirements for the MegaRAID 320 storage adapters. Table 3.9 lists the maximum power requirements, which include SCSI TERMPWR, under normal operation.
Relative humidity range: 5% to 90% noncondensing 3.3.6 Safety Characteristics All MegaRAID 320 storage adapters meet or exceed the requirements of UL flammability rating 94 V0. Each bare board is also marked with the supplier’s name or trademark, type, and UL flammability rating. Since these boards are installed in a PCI bus slot, all voltages are below the SELV 42.4 V limit.
