Re: laod balancing

Hi,
I am sending you some threads links where you can see the differences between e.g.

HP-UX
a)the Secure Path (dynamic LB) and PVlinks (static LB)in HP-UX (both EVA AP and AA):

Windows
b) EVA active/passive (Secure Path or MPIO basic) and EVA Windows active/active (MPIO FF DSM) multipath/loadbalancing solutions (slides 44-48)

the pain is one part of the reality

Re: laod balancing

For load balancing, your server needs more than one data path - usually provided with multiple adapters or at least a dual-port adapter. Next the storage array must present the data via multiple host ports (I am simplifying things a bit).


Static load balancing means that access to one storage ressource (e.g. a logical/virtual disk or a RAIDset - whatever it is called in the storage array's own terminology) goes along one path and does not change automatically.

Some software on the host or you as a user have the option to access a different storage ressource along a different path in order not to overload single paths.


Dynamic load balancing means that the multipath component on the host uses all or a reasonable subset of the paths available to the storage ressource in order to 'level out' the access.
