Large Send Offload Transmit Requests The number of times the adapter was requested to transmit a packet performing TCP segmentation. Total Offload TCP Connections The total number of offloaded TCP connections. Viewing and Configuring Resource Reservations NOTES: Resource Reservation information is only available for Broadcom NetXtreme II adapters and VBD drivers. Not all offload technologies are available with all adapters. The Resource Reservations section shows the number of connections allocated to an offload technology: TOE and iSCSI. TCP Offload Engine (TOE) for accelerating TCP over 1 GbE and 10 GbE. Internet Small Computer Systems Interface (iSCSI) offload for accelerating network storage access featuring centralized boot functionality (iSCSI boot). You can also view the number of unlicensed resources and unallocated resources. TOE and iSCSI can only be configured on certain adapters and require a license key. License keys are installed on the motherboard for use with LOMs and are preprogrammed in add-in NICs. TOE is a technology best suited for long-term TCP connections. TOE used in conjunction with applications that primarily deal with short-term connections may see suboptimal performance when compared to not using TOE. A short-term connection is a TCP connection that is established for only a few seconds at most, often less than one second. The overhead of establishing and tearing down the TCP connection with short-term connections may diminish the benefit that TOE provides. An example of an application that uses short-term connections is a web server that is not behind a load balancer. TCP connections for HTTP sessions are very short-lived and last only long enough to serve up a web page, after which the TCP connection is terminated. On the other hand, the same web server behind a load balancer benefits greatly from TOE since the TCP connections are long-lived between the web server and the load balancer. In contrast, a backup application is very likely to benefit from TOE since backup applications establish long-term connections between the server and the client. To view resource reservations 1.
