5.7.1 PCI-to-PCI Bridge
AlphaServer 1000A systems have a PCI-to-PCI bridge (DECchip 21050) on the
motherboard.
• Physical PCI slots 11, 12, and 13 (primary PCI) are located before the bridge.
• Physical PCI slots 1, 2, 3 and 4 (secondary PCI) are located behind the bridge.
Some PCI options are restricted to the primary PCI bus, slots 11, 12, and 13.
Refer to the following documents for restrictions on specific PCI options:
• AlphaServer 1000A READ THIS FIRST—shipped with the system.
• AlphaServer 1000A Supported Options List—The options list is available from
the Internet at the following locations:

5.8 SCSI Buses
An onboard, PCI-based controller on the motherboard provides 8-bit Fast
SCSI-2 support for removable-media devices, and 16-bit fast-wide SCSI-2
support for internal StorageWorks devices. The onboard controller supports a
50-pin connector for the 5.25 inch removable-media devices, as well as a 68-pin
connector for the fast-wide SCSI devices.
The Fast SCSI-2 adapter on the motherboard supports up to two 5.25-inch,
internal half-height removable-media devices.
This bus can be extended to the internal StorageWorks shelf or an external
expander to support up to seven drives.
5.8.1 Internal StorageWorks Shelf
The AlphaServer 1000A deskside ‘‘wide tower’’ supports an internal StorageWorks
shelf that can support up to seven SCSI disk drives in a dual-bus configuration.
The backplane of the internal StorageWorks shelf supplies the drive’s SCSI node
ID according to the location of the drive within the storage shelf. Each internal
StorageWorks shelf can be configured in one of two ways:
• Single bus — Up to seven drives, each with a unique node ID.
• Dual bus — Up to seven drives (bus A node IDs 0–3, bus B node IDs 0–2).
For AlphaServer 1000A enclosures, the internal storage shelf configuration is
controlled by a StorageWorks jumper cable (17-04021-01).
