IBM Storage Networking SAN256B-7 Installation, Service And User Manual page 25

Chapter 1. Device overview
The IBM SAN256B-7 offers the following features and capabilities
• Redundant and hot-swappable SFP+, SFP28, QSFP+, and Gen 7 QSFP transceivers; port, extension,
control processor (CP), and core routing (CR) blades; power supply assemblies, fan assemblies, and
WWN cards that enable a high-availability platform and allow nondisruptive software upgrades for
mission-critical SAN applications.
• Support for the following features when using the FC32-64 blade:
– Up to 16 QSFP ports on each FC32-64 port blade that provide 4x32Gb/s, 4x16Gb/s, 4x8Gb/s,
4x4Gb/s, 4x25GbE, or 40GbE operation. Port speeds for 4x32Gb/s transceivers can auto-negotiate
between 4x32Gb/s and 4x16Gb/s. Port speeds for 4x16Gb/s transceivers can auto-negotiate
between 4x16Gb/s, 4x8Gb/s, and 4x4Gb/s.
– Flexport technology that allows you to configure each of the 16 QSFP ports on a blade for FC
operation or Ethernet operation for FCoE connections. For details on supported transceivers and
speeds, see "Supported transceivers and cables" on page 61.
– Up to four blades and all FC transceivers installed, up to 256 32Gb/s external ports are possible in a
single chassis, enabling high-density SAN configurations with a reduced footprint.
– Trunking technology that allows groups of up to eight ports to create high-performance 256Gb/s ISL
trunks between switches using 32Gb/s ports.
• Support for the following features when using the FC64-48 blade:
– Port blade with 48 front-end 64Gb/s FC SFP+ ports with the edge switch interconnect to the core
blades.
– Supported SFPs include 10Gb/s, 32Gb/s, and 64Gb/s FC.
– Support for 48 Fibre Channel ports on each FC64-48 port blade that provide 64Gb/s, 32Gb/s,
16Gb/s, 10Gb/s, and 8Gb/s. The 10Gb/s transceivers can be used for any port on the FC64-48 port
blades. Note that 10Gb/s transceivers on the FC64-48 and SX6 blade are not interchangeable. For
details on supported transceivers and speeds, see "Supported transceivers and cables" on page
61.
– Trunking technology groups up to eight ports to create high-performance 512Gb/s ISL trunks
between switches using 64Gb/s ports.
• Support for the following features when using the FC32-X7-48 blade:
– Port blade with 48 front-end 32Gb/s FC SFP+ ports with edge switch interconnect to the core blades.
– Supported SFPs include 32Gb/s, 16Gb/s, and 10Gb/s FC.
– Support for 48 Fibre Channel ports on each FC32-X7-48 port blade that provide 32Gb/s, 16Gb/s,
10Gb/s, 8Gb/s, and 4Gb/s. The 10Gb/s transceivers can be used for any port on the FC32-X7-48 port
blades. Note that 10Gb/s transceivers on the FC32-X7-48 and SX6 blade are not interchangeable.
For details on supported transceivers and speeds, see "Supported transceivers and cables" on page
61.
– Trunking technology groups up to eight ports to create high-performance 256Gb/s ISL trunks
between switches using 32Gb/s ports.
• Support for the following features when using the SX6 extension blade:
– 16 Fibre Channel ports supporting 4, 8, 16, and 32Gb/s.
– 16GbE ports supporting 1 or 10Gb/s.
– Two GbE ports supporting 40Gb/s on SX6 extension blades.
Note: 10Gb/s transceivers on the FC64-48 and the FC32-X7-48 are not interchangeable with the SX6
Blade. For details on supported transceivers and speeds, see "Supported transceivers and cables" on
page 61
