HP/Convex SPP2000 (S-Class/X-Class) Clustering
4.49.3 Clustering
Multiple Exemplar SPP2000/HP S-Class systems can be connected together to form a single large sys-
tem, a “Wall” /X-Class.
Up two 32 single nodes can be clustered together to form a system with up to
512 processors
512GB of RAM
768 PCI slots
640 SCSI drives
Clustered SPP2000s/X-Class are ccNUMA computers; they are not fully conformant to the PA-
RISC 2.0 specification (and thus do not run standard HP-UX).
Multiple systems are connected via two CTI rings: these links attach to the eight memory con-
trollers of a node. A single system attaches to other single “nodes” and their respective crossbars
with a node-to-note data rate of 3.8GB/s.
The two rings are called X-ring and Y-ring.
The links are implementations of the IEEE SCI from Convex Convex Toroidal Interconnect.
Each node’s main memory is globally accessible from other nodes on the CTI network (that is,
local memory is globally shared).
A part of each system’s main memory is reserved for cache memory for the CTI network (config-
ured statically at boot time).
4.49.4 External connectors
68-pin VHDCI Ultra LVD external SCSI
Three DB9 male RS232C serial (local console, remote console, general purpose) via a DB25 “M
cable”
10/100Mbit Ethernet TP/RJ45
10/100Mbit Ethernet TP/RJ45 LAN console
4.49.5 ROM update
There is an firmware update available for the SPP2000 which contains the latest version 4.2.1.
