Would running an MDS and OST on a 32bit hardware hamper any performance or scalability? These boxes all have 4GB of memory.

Depending on load.> These boxes all have 4GB of memory.A 32-bit kernel can only access the first GB of memory or so. The other 3GB would be unused by a Lustre OSS or MDS. So if load demanded more than 1GB of memory you really need to go to 64-bit to escape the 1GB memory limitation. b. -------------- next part -------------- A non-text attachment was scrubbed...
