Features - Chelsio T5 Installation And User Manual

Chapter 1. Introduction
The performance of this iSCSI stack is outstanding and when used with Chelsio's hardware it is
enhanced further. Because of the tight integration with Chelsio's TOE adapters, this software
has a distinct performance advantage over the regular NIC. The entire solution, which includes
this software, Chelsio TOE hardware, an appropriate base computer system – including a high
end disk subsystem, has industry leading performance. This can be seen when the entire
solution is compared to others based on other technologies currently available on the market in
terms of throughput and IOPS.
