We direct-connected to LSI back-ends, and the only real stumbling blocks were in the intitial setup phase where we assigned wwns to various hosts and host groups. The wwns were a concatenation of the port IDs on both ends, rather than just on the host end. So if we moved wires around, we had to re-assign wwns to the hosts and host groups.
Failover was no problem, MMP worked correctly. IIRC, we had to specify which devices used SRP and which used IPoIB, but that's about it. It's been awhile since we did it, so my memory make be flaky -Ben Evans [email protected] -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Brian O'Connor Sent: Monday, March 28, 2011 1:21 AM To: [email protected] Subject: [Lustre-discuss] IB storage as an OST target Anybody had any experience using an IB based storage target as an OST? Apart from the obvious issue of separating the IB SAN(SRP/SER) storage traffic from the Lustre traffic are there any issues? What about failover? -- Brian O'Connor ----------------------------------------------------------------------- SGI Consulting Email: [email protected], Mobile +61 417 746 452 Phone: +61 3 9963 1900, Fax: +61 3 9963 1902 357 Camberwell Road, Camberwell, Victoria, 3124 AUSTRALIA http://www.sgi.com/support/services ----------------------------------------------------------------------- _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
