5.4.4. Ultra-SCSI Director
The Ultra SCSI director is a single card that has four differential wide interfaces for connection to host
systems and one high-speed path to cache. It can attach to hosts supporting Ultra-SCSI connectivity
and Fast-Wide differential SCSI connectivity. The Ultra SCSI director contains two advanced
microprocessors that process commands and data from the host and manage access to cache. On each
Ultra-SCSI channel director, data transfers from the host to cache occur as four concurrent operations.
Each Ultra SCSI director can support up to 960 logical volumes (with a maximum of 2,048 logical
volumes per Symmetrix 8730 or 8430)
5.4.5. 4-Port Fibre Channel Director
The new multi-mode Fibre Channel director is a single card that has four FC ANSI compliant 1-
Gigabit Fibre Channel interfaces for connection to open systems hosts. They extend the Symmetrix
Fibre Channel connectivity to 32 independent Fibre Channel ports. The multi-mode Fibre Channel
directors require at least Enginuity 5567.29.15s and version 4.3 of the SymAPI.
5.4.6. Multi Mode Fibre Channel Director
The multi-mode Fibre Channel director is a single card that has two FC ANSI compliant 1-Gigabit
Fibre Channel interfaces for connection to open systems hosts and one high-speed path to cache. The
Fibre Channel director contains two advanced microprocessors that process commands and data from
the host and manage access to cache. The Fibre Channel SCSI protocol mapping and upper level
protocol layers are both implemented within the director. Each Fibre Channel director can support up
to 256 logical volumes per Symmetrix system. The two physical interfaces are 52µ multi mode fiber.
