Software requirements None Compatibility The EXP2500 is supported for direct connection to selected IBM System x servers using the IBM ServeRAID M5025 SAS/SATA Controller (IBM part number 46M0830). The EXP2500 is compatible with all System x servers and operating systems supported by the ServeRAID M5025 controller. For ServeRAID M5025 compatibility information, refer to the following: • IBM ServerProven® program: http://www.ibm.com/servers/eserver/serverproven/compat/us/ • IBM System x Configuration and Options Guide • IBM ServeRAID M5025 SAS/SATA Controller Hardware Announcement ZG10-0252, dated August 10, 2010 Limitations A maximum of seventeen EXP2512 enclosures or a maximum of nine EXP2524 enclosures can be connected to a single RAID controller port in a daisy-chain configuration. When intermixing EXP2512 and EXP2524 enclosures in a daisy-chain configuration to a single RAID controller port, refer to the table below for supported intermix combinations. "Y" designates a supported intermix configuration.

EXP2500 is not supported for attachment to IBM System Storage DS3000 Storage Controllers or IBM System Storage DS3500 Express Storage Systems. EXP2500 supports a single environmental services module. The environmental services module has two upstream (initiator) 6 Gbps SAS ports that can be used for connection to RAID controller ports. However, EXP2500 does not support zoning of the disk drives within the enclosure, therefore an EXP2500 should only be connected to one RAID controller port (one server). Planning information Customer responsibilities Physical configuration and installation planning, along with machine set up and configuration, are customer responsibilities.

EXP2512 and EXP2524 Express Storage Enclosures Installation, User's, and Maintenance Guide for additional information. You are responsible for downloading or obtaining from IBM, and installing designated Machine Code (microcode, basic input/output system code (called "BIOS"), utility programs, device drivers, and diagnostics delivered with an IBM machine) and other software updates in a timely manner from an IBM Internet website or from other electronic media, and following the instructions that IBM provides. You may request IBM to install Machine Code changes; however, you may be charged for that service. Cable orders RAID Controller and daisy-chain connections Cables are required to connect an EXP2500 to a RAID controller port and to connect an EXP2500 to another EXP2500 in a daisy-chain configuration. The EXP2500 requires a mini SAS 4x cable terminated with an SFF-8088 connector. As a convenience, a limited selection of cables can be ordered with an EXP2500: • 1 m SAS Cable • 3 m SAS Cable Refer to the Product number section for feature numbers and part numbers. In many situations, the required lengths and installation of host attachment cables will be unique to each customer's configuration and facility specifications. IBM Network Integration and Deployment Services, offered by IBM Global Services, can provide assistance for these unique cabling and installation requirements. Enclosure management Cables are required if the EXP2500 will be managed "out of band" using the 10/100 Mbps Ethernet management port. The EXP2500 requires a Category 5 or Category 5E Ethernet cable terminated with an 8P8C modular connector (RJ45 compatible connector). This cable must be supplied by the customer and is not available for ordering with an EXP2500. Security, auditability, and control This product uses the security and auditability features of host hardware. The customer is responsible for evaluation, selection, and implementation of security features, administrative procedures, and appropriate controls in application systems and communications facilities.
