The card should be an ATTO 42ES whcih supports 255 LUNS per channel
Here's the info from the attached link
Consider the following Celerity FC host adapter guidelines:
• ATTO 4-Gb and 8-Gb FC cards (PCI-X and PCIe only) are supported. • Latest HP-specific ATTO Celerity FC host adapter driver • Latest HP-specific ATTO Configuration Tool • A maximum of 256 targets per host adapter channel are supported. • A maximum of 255 logical unit numbers (LUNs) per host adapter channel are supported. • PowerPC- and Intel-based servers are supported.
Hope that helps
