691367-B21 HPE Virtual Connect FlexFabric-20/40 F8 Module

691367-B21 is the HPE Virtual Connect FlexFabric-20/40 F8 Module for c-Class BladeSystem. It converges Ethernet and Fibre Channel traffic using Flex-10 and Flex-20 technology with Fibre Channel over Ethernet and accelerated iSCSI over 10Gb/20Gb connections to servers with FlexFabric adapters, such as the FlexFabric 20Gb 2-port 650FLB and 630FLB.

Sixteen 10/20Gb downlinks run through the midplane to the blades, and each downlink supports up to 3 FlexNICs and 1 FlexHBA or 4 FlexNICs. A redundant pair provides eight adjustable downlink connections to a dual-port FlexFabric adapter: six Ethernet and two Fibre Channel, six Ethernet and two iSCSI, or eight Ethernet.

Eight SFP+ uplinks run as 1/10Gb Ethernet or 2/4/8Gb Fibre Channel, and four QSFP+ uplinks run as 1x40Gb or 4x10Gb Ethernet. That makes up to twelve uplinks without splitter cables and up to 24 with splitter cables. The bridging fabric is line-rate, full-duplex and non-blocking at 1.2 Tbps, jumbo frames reach 9216 bytes, and latency is 1.0 µs on Ethernet-only ports and 1.8 µs on Ethernet/Fibre Channel ports.

The module weighs 2.05 kg (4.5 lb) and ships at approximately 2.7 kg (6.0 lb). It is supported on c7000 enclosures with SKUs 5XXXXX-B21, 6XXXXX-B21 and 7XXXXX-B21, and the enclosure needs the ten-fan configuration. The TAA-compliant version is 691367-B22, and the spare number is 699350-001.
