Understand... of course they never really gave the distribution a chance to earn money... Solaris 11 has yet to be released. :-) Had they kept Xen in Solaris they may have found people moving to it. I know we were going to purchase hardware and software from Oracle. We needed to simplify our environment (axe VMware, get down or as close to having a single OS as possible), get rid of EOSL equipment, and consolidate as much as possible to a single vendor... moving to OSOL (or Solaris 11) on Oracle SUN hardware seemed like it would be THE platform to finally do that. > > > We were looking to replace a pair of clustered > V880s with 12 shared D2 arrays stuffed with 72GB > disks and other various servers (clustered for NBU > master, DNS/SMTP servers, a couple windows boxes, and > a pair of VMware servers on IBM hardware) down into a > pair of clustered servers (thinking X4470) with dual > attached SAS arrays filled with 2TB disks (moving > from ~8TB to ~16TB with capactiy to quickly go to > ~32TB). > > Clustered, how?

Solaris Cluster (or whatever it is today) if it had the agent... otherwise it would be VCS with a custom agent. Remus might work for the DomUs (if you're okay with the data duplication it uses) but doesn't address the data share in the Dom0... and putting the share into a DomU wouldn't work for Remus as we're not about to duplicate 8TB+ of data. > > The Dom0s can serve the data and be netbackup media > servers and the rest could have been virtualized into > DomU's with NBU client software.

Cluster can control the storage failover for the 8TB+ data storage in the Dom0 and, had the agent been released, the DomU failover. The biggest thing was keeping the 8TB+ on ZFS (no discussion) and in the Dom0 with the NBU media server. With OracleVM we'd lose ZFS... unless we can pass the disks directly to a DomU running Solaris or OSOL (which I didn't think was currently possible with OracleVM... please correct me if I'm wrong) > > I would consider going with OracleVM but I'm not > sure I'm going to get money to add seperate HA > file/NBU media servers into the picture.
