    DS3500 delivers superior price to performance ratios, functionality, scalability and ease of use for the entry-level storage user. The DS3500 supports intermixing four 1Gbps iSCSI or four 8Gbps FC host ports with its native 6Gbps SAS interfaces. This flexible and multi-purpose dual protocol approach allows organizations to implement a single storage system to support all of their shared storage requirements, there by maximizing productivity, reliability, and cost.

This configuration offers both redundant Fibre Channel host connections and redundant controllers and offers improved redundancy compared to the sample configuration shown in Figure 4-32.
  • Page 147 Best practise is to always use redundant host-side connections. Note: Because there are four Fibre Channel host ports on the DS3500 (when the optional Fibre Channel host interface card is installed) a maximum of two direct attached hosts with redundant paths can be connected to a single controller DS3500 storage subsystem.

    Figure 4-35 Two hosts with redundant connections to a dual controller DS3500 If you need to connect more than four Fibre Channel hosts to a DS3500 storage subsystem using redundant host connections then you will need to use a SAN fabric infrastructure. This is discussed in the next section.
  • Page 150 Inter-Switch Link. SAN zoning When you connect a DS3500 storage subsystem to a switched fabric SAN infrastructure you will normally need to implement a SAN zoning configuration on the SAN switch. In this section we provide a brief overview of SAN zoning, and describe some general guidelines for implementing a zoning configuration in your SAN infrastructure.
  • Page 151 Attention: You must always implement a SAN zoning configuration when connecting two or more host bus adapters to a DS3500 storage subsystem through a SAN switched fabric infrastructure. SAN zoning is mandatory when a SAN includes more than one operating system type, or when both tape and disk devices are attached.
  • Page 152 Fibre Channel adapter in one of your servers. Most storage systems such as the DS3500, storage subsystem, and IBM Tape Libraries have a WWN tied to the Vital Product Data of the system unit, so individual parts can usually be replaced with no effect on zoning.

In a cross-connected SAN fabric, each host bus adapter has a connection to both controllers in a dual controller DS3500 storage subsystem. Some applications and host operating systems require a cross-connected SAN fabric.
