Feature
Description
Product number
8960-F64 (Front/Port-Side Exhaust).
8960-N64 (Rear/Non-Port Side Exhaust).
Fibre Channel ports
Switch mode (default): Minimum of 24 ports and maximum of 64 ports
configuration. Port numbers above minimum are enabled through 12-port
SFP+ increments with Ports on Demand (PoD) licenses, and through one
4-port QSFP PoD, providing 16-port increments through a Q-Flex license:
E_Ports, F_Ports, D_Ports, and EX_Ports.
Access Gateway default port mapping: 40 SFP+ F_Ports, 8 SFP+ N_Ports.
Scalability
Full-fabric architecture with a maximum of 239 switches.
Certified maximum
6,000 active nodes; 56 switches, 19 hops in Fabric OS fabrics; larger fabrics
certified as required.
Fibre Channel
performance
4.25 Gbps line speed, full duplex.
8.5 Gbps line speed, full duplex.
10.53 Gbps line speed, full duplex.
14.025 Gbps line speed, full duplex.
28.05 Gbps, full duplex.
Auto-sensing of 4, 8, 16, 32 Gbps port speeds and capable of supporting
128 Gbps speeds.
10 Gbps optionally programmable to fixed port speed.
ISL trunking
Frame-based trunking with up to eight 32 Gbps ports per ISL trunk; up to 256
Gbps per ISL trunk.
Exchange-based load balancing across ISLs with DPS included in Fabric OS.
Aggregate
bandwidth
2 Tbps.
Maximum fabric
latency
Latency for locally switched ports is 700 ns; encryption/compression is 1 µsec
per node.
Maximum frame
size
2,112-byte payload.
Frame buffers
15,360 dynamically allocated.
Classes of service
Class 2, Class 3, Class F (inter-switch frames).
Port types
D_Port (ClearLink Diagnostic Port), E_Port, EX_Port, F_Port, AE_Port
optional port-type control.
b-type Access Gateway mode: F_Port and NPIV-enabled N_Port.
Data traffic types
Fabric switches supporting unicast.
Hot-swap
components
Power supplies, fan modules, SFPs.
Warranty
One-year; customer-replaceable unit (CRU); and onsite, next-business-day
response; warranty service upgrades are available.
