Sure. But it counts for all machines of the same endianess, not just ppc64. > But why? The linux kernel has no problems providing an endian-clean > and wordsize-clean environment to operate in. Sure, but Lustre is quite a bit more than just a driver in any one Linux kernel. There is an entire networking stack written from the ground up, not to mention the VFS client and server modules. And Lustre is a lot bigger (I mean in concept) than the Linux kernel. The Linux kernel has the luxury of only having to deal with a single endianess at a time. Lustre has to deal with potentially different endianesses all at once. To be sure, these are not at all insurmountable difficulties. They are just things that are not being demanded enough to warrant attention (yet). As always, we accept patches. > Are Sparc64 servers supported? I don't know. Are they the same endianess as ppc64? If so, then no. b.
