PARAMNet-II
C-DAC has forged its decades
of Hardware Technology Development expertise, in the state-of-the-art
areas of VLSI Design, High Speed Networking and Digital
System Design to develop Next Generation High Performance
System Area Network (SAN) PARAMNet-II with speeds of 2.5
Gbits/Sec full duplex supporting multiple software interfaces
like Virtual Interface Architecture (VIA) and Active Messages
(AM). PARAMNet-II, with ultralow latency & high bandwidth,
offers the best price/performance ratio for interconnecting
High Performance Clusters of Workstations, Servers, Personal
Computers and Single Board Computers.
PARAMNet-II is the prime
interconnect fabric for connecting Compute Nodes, File Servers
and Graphics Nodes in C-DAC's High Performance Computing
Cluster PARAM Padma with a peak Computing Power of One Teraflop,
one of the most powerful supercomputers deployed for High
Performance Technical and Business Computing Applications
in Asia Pacific Region.
The
major components of PARAMNet-II are:
1. SAN
Switch: 8/16 Ports
2. PARAMNet-II
NIC with CCP-III communication co-processor
3. C-DAC's
Virtual Interface Provider Library (C-VIPL)
PARAMNet-II SCALABILITY
A single switch can support up to eight
(SANSW8) or sixteen (SANSW16) hosts. For supporting more
hosts, a multistage network is necessary. This network can
be made non-blocking (higher performance, requires larger
number of switches), or blocking type (low performance,
requires lesser number of switches). Various topologies
are possible by modifying the routing tables of the switches.
SYSTEM LEVEL BLOCK DIAGRAM FOR PARAMNet-II:
PARAMNet-II network comprises of N hosts
connected in non-blocking fat tree topology. For more than
eight/sixteen hosts, multiple SANSW8/SANSW16 switches are
required. The following figures shows a non-blocking configuration
required to support:
32-hosts, using six SANSW16 Switches
64-hosts, using twelve SANSW16 Switches
Since the switch latencies are very
low, the multiple levels of switches have very little overheads. It is possible to build similar larger non-blocking configurations
using SANSW8/SANSW16 switches.
