36.4 GB, 73.4 GB or 146.8 GB 15K rpm drives. Each of the four six-packs disk drive 
enclosure can be attached independently to an Ultra320 SCSI or Ultra320 SCSI RAID 
adapter. For high available configurations, a dual bus repeater card (FC 5742) allows each 
six-pack to be attached to two SCSI adapters, installed in one or multiple servers or logical 
partitions. Optionally, the two front or two rear six-packs can be connected together to form a 
single Ultra320 SCSI bus of 12 drives.
2.9.2  IBM System Storage N3000 and N5000
The IBM System Storage N3000 and N5000 line of iSCSI-enabled storage offerings provides 
the flexibility for implementing a Storage Area Network over an Ethernet network. The N3000 
supports up to 16.8 TB of physical storage and the N5000 supports up to 84 TB of physical 
disk. Additional information about IBM iSCSI-based storage systems is available at:
2.9.3  IBM TotalStorage DS4000 Series
The IBM System Storage DS4000™ line of Fibre Channel-enabled Storage offerings 
provides a wide range of storage solutions for your Storage Area Network (SAN). The 
DS4000 Storage server family consists of the following models: DS4100, DS4300, DS4500, 
and DS4800. The Model DS4100 Express model is the smallest model and scales up to 
44.8 TB; the Model DS4800 is the largest and scales up to 89.6 TB of disk storage at the time 
of this writing. Model DS4300 provides up to 16 bootable partitions, or 64 bootable partitions 
if the turbo option is selected, that are attached with a Fibre Channel Adapter. Model DS4500 
provides up to 64 bootable partitions. Model DS4800 provides 4 GB switched interfaces. In 
most cases, both the IBM TotalStorage DS4000 family and the IBM System p5 servers are 
connected to a storage area network. If you only need space for the 
rootvg
, the Model 
DS4100 is a good solution.

2.9.4  IBM TotalStorage DS6000 and DS8000 Series
The IBM TotalStorage Models DS6000™ and DS8000™ are the high-end premier storage 
solution for use in storage area networks and use POWER technology-based design to 
provide fast and efficient serving of data. The IBM TotalStorage DS6000 provides enterprise 
class capabilities in a space-efficient modular package. It scales to 67.2 TB of physical 
storage capacity by adding storage expansion enclosures. The Model DS8000 series is the 
flagship of the IBM TotalStorage DS family. The DS8000 scales to 192 TB; however, the 
system architecture is designed to scale to over one petabyte. The Model DS6000 and 
DS8000 systems can also be used to provide disk space for booting logical partitions 
(LPARs) or partitions using Micro-Partitioning technology. DS6000 and DS8000 and the IBM 
System p5 servers are usually connected together to a storage area network.
