Concurrent sessions on HP BladeSystem Onboard Administrator
When running concurrent sessions on an HP BladeSystem Onboard Administrator (OA), the BladeSystem OA network and
processor workload may affect the number of users able to log in. There is no built-in restriction on the number of logins to a
BladeSystem OA; however, the number of logins can be limited by heavy network and processor workloads.
Login scenarios can affect the BladeSystem OA network and processor utilization as follows:
•
Command-line logins:
Command line logins to the BladeSystem OA, including processing “connect” commands to server
blades or switches, are the least demanding on network and processor bandwidth.
•
Graphical user interface (GUI) logins:
GUI logins are a little more demanding because multiple connections are necessary to
carry event data (logins to multiple enclosures linked together will add to the workload). The BladeSystem OA should support
a dozen or more GUI logins.
•
Enclosure DVD:
The Enclosure DVD login uses the highest workload because the BladeSystem OA is servicing connections to
multiple servers sharing the CD or DVD media in a DVD drive attached to the BladeSystem OA USB port in the HP
BladeSystem c7000 Enclosure or HP BladeSystem c3000 Enclosure. The enclosure DVD can be attached to all the servers;
however, this will likely slow down the response time of concurrent GUI sessions. The fastest shared enclosure DVD
performance is obtained when all the servers are rebooted to the enclosure DVD at the same time to minimize DVD seek time
(many of the requests will be serviced from the OA file cache instead of requiring a seek to a different spot on the DVD disk
which slows down all the other pending requests).
