如何建立8G的数据带宽？都需要什么东东？
利用BROCADE的干线合并技术。
两台2GB的光纤交换机通过E-PORT连接：叫做ISL。
8GB带宽就是两个交换机通过4条ISL进行连接（四条物理连接），但是通过BROCADE的干线合并（TRUNKING）技术在逻辑上可以看作一条链路，并且实现了ISL间的负载均衡。
Brocade Interswitch Link (ISL) Trunking is an optionally licensed product available on the
SilkWorm 3000 series switches with Fabric OS version 3.0. Brocade ISL Trunking is managed
using telnet commands or the Brocade Web Tools interface.
The Brocade ISL Trunking feature allows up to four ISLs, connections between two switches
through an Expansion Port (E_Port), to merge logically into a single link. When using Brocade ISL
Trunking to aggregate bandwidth of up to four ports, the speed of the ISLs between switches in a
fabric is quadrupled. For example, at 2 Gb/Sec speeds, Brocade ISL Trunking delivers ISL
throughput of up to 8 Gb/Sec.
Brocade ISL Trunking also supports high-bandwidth, large-scale Storage Area Networks (SANs)
which include core switches. The primary task of Brocade ISL Trunking is to route data and edge
switches that aggregate connections to servers and storage. Brocade ISL Trunking simplifies
network design and reduces the cost of storage management by optimizing bandwidth utilization
and enabling load sharing of traffic at the frame-level. |
