IBM 750 manual Drawer availability

total number of IBM i processor license entitlements are not updated, and you may see IBM i license noncompliance warning messages from the CBU system. These warning messages in this situation do not mean you are not in compliance. Before you can temporarily transfer 5250 entitlements, you must have more than one 5250 Enterprise Enablement entitlement on the primary server and at least one 5250 Enterprise Enablement entitlement on the CBU system. You can then transfer the entitlements that are not required on the primary server during the time of transfer and that are above the minimum of one entitlement.

For example, if you have a 6-core Power 750 as your primary system with two IBM i processor license entitlements (one above the minimum) and two 5250 Enterprise Enablement entitlements (one above the minimum), you can temporarily transfer only one IBM i entitlement and one 5250 Enterprise Enablement entitlement. During the temporary transfer, the CBU system's internal records of its total number of IBM i processor entitlements is not updated, and you may see IBM i license noncompliance warning messages from the CBU system.

If your primary or CBU machine is sold or discontinued from use, any temporary entitlement transfers must be returned to the machine on which they were originally acquired. For CBU registration and further information, visit

I/O drawer availability

Four 12X attached I/O drawers are supported on the Power 750, providing extensive capability to expand the overall server expandability and connectivity.

•Feature 5802 provides PCIe slots and SSF SAS disk slots.

•Feature 5877 provides PCIe slots.

•Feature 5796 provides PCI-X slots.

•The 7314-G30 provides PCI-X slots (supported but not orderable).

Three disk-only I/O drawers are also supported, providing large storage capacity and multiple partition support:

•Feature 5886 EXP12S holds 3.5-inch SAS disk or SSD.

•Feature 5786 EXP24 holds 3.5-inch SCSI disk (used for migrating existing SCSI drives).

•The 7031-D24 holds 3.5-inch SCSI disk (supported but not orderable).

TotalStorage® EXP24 Disk Drawer (#5786)(supported only -- not orderable)

The TotalStorage EXP24 (#5786) is a 4 EIA unit drawer and mounts in a 19-inch rack. The front of the IBM TotalStorage EXP24 Ultra320 SCSI Expandable Storage Disk Enclosure has bays for up to 12 disk drives organized in two SCSI groups of up to six drives. The rear also has bays for up to 12 disk drives organized in two additional SCSI groups of up to six drives plus slots for the four SCSI interface cards. Each SCSI drive group can be connected by either a Single Bus Ultra320 SCSI Repeater Card (#5741) or a Dual Bus Ultra320 SCSI Repeater Card (#5742). This allows the EXP24 to be configured as four sets of six bays, two sets of 12 bays, or two sets of six bays plus one set of 12 bays.

The EXP24 feature 5786 has three cooling fans and two power supplies to provide redundant power and cooling. The SCSI disk drives contained in the EXP24 are controlled by PCI-X SCSI adapters connected to the EXP24 SCSI repeater cards via SCSI cables. The PCI-X adapters are located in the Power 750 system unit or in an attached I/O drawer with PCI-X slots.

The EXP24S SCSI Disk Drawer is an earlier technology drawer compared to the later SAS EXP12S drawer. It is used to house the older SCSI disk drives that are supported but no longer orderable.
