[SRX] How to move SPC cards to a different slot on high-end SRX devices ...
SPC slot GRANT Continuity. General purpose UNIBUS backplanes with SPC slots route Interrupt GRANT (BG4,5,6,7) and DMA GRANT (NPG) in a special way: All five BG* and NPG must be bridged on empty slots, connecting IN and OUT signals.

Statistical Process Control (SPC) SPC applies statistical process control to quality and defect data that is collected during the manufacturing process, allowing manufacturers to identify, analyze, and solve potential problems while production continues - before equipment is shut down, material is scrapped, and production time is lost.

Some investigation of power to the DL11, which was sitting in one of the backplane SPC slots (26-28), showed that there was no distribution of +15V to pin CU1 of these slots where the DL11 was expecting it. So that explained the bad driver output voltages.

To calculate this value, add the total input power requirement (in watts) for the two zones together and multiply the sum by 3.41 as shown in Table 9 . Table 9: Calculating Thermal Output for SRX5800 Firewall with SCB3, IOC3, and RE2. Power Supply.

Small Peripheral Controller or SPC was DEC's name for a board slot in the backplanes of UNIBUS PDP-11s into which small device controllers, etc, could be plugged. It was a quad-high slot, occupying rows C-F in a hex slot.

Technically, a MUD slot only describes the A-B connectors; most backplanes also provided SPC functionality in the C-F connectors (needed for signals for interrupts or DMA, for devices which did those), with most UNIBUS signals present in both; the combination is sometimes called a 'MUD/SPC' slot.
How to install SPC or SPC II modules in an SRX5000 chassis cluster
November 2, 2020. Chinese vendor MacroSAN's new test result adds to near total far East domination of the SPC-1 storage benchmark. SPC-1 measures the ability of the storage array to run input-output operations, measured in calculated SPC-1 IOPS. MacroSAN last month managed 11,000,576 SPC-1 IOPS, the second fastest on the board behind Huawei.

Peripheral Component Interconnect (PCI) is a local computer bus for attaching hardware devices in a computer and is part of the PCI Local Bus standard. The PCI bus supports the functions found on a processor bus but in a standardized format that is independent of any given processor's native bus. Devices connected to the PCI bus appear to a bus master to be connected directly to its own bus ...
Calculating Power Requirements for the SRX5800 Firewall
This article explains how to install SPC or SPC II modules in an existing SRX5000 chassis cluster using the minimum downtime procedure. Prerequisites: If the chassis cluster is operating in active-active mode, you must transition it to active-passive mode before using this procedure.
