And if you don't like Xen on RHEL/CentOS you can switch to KVM on RHEL. Or (heaven forbid) VMWare Server on RHEL or VMWare ESX which was partially based on RHEL. Even Xen started life with a big code import from Linux. And if you go the Xen route and decide you really don't like Linux you can run Xen on OpenSolaris. Open Source is good - you can choose Linux first and still have good escape routes. >> > Any blatant negatives for Linux as a platform? ZFS is only on *Solaris and FreeBSD (albeit an old one). Linux doesn't yet have a stable, consistent COW filesystem. Certainly a combination of the two is a great win. If you assume ZFS for storage virtualization, Linux has the advantage of being able to (p)NFS mount the data, so you can do file-level snapshotting and data de-duplication. You could also run Windows-based clouds with a ZFS backend, but you'd have to use an iSCSI backend which loses the nice snapshotting capabilities and drives everything back to the block device level of granularity because Windows doesn't play nicely with everybody else. -Bill -- Bill McGonigle, Owner BFC Computing, LLC http://bfccomputing.com/ Telephone: +1.603.448.4440 Email, IM, VOIP: b...@bfccomputing.com VCard: http://bfccomputing.com/vcard/bill.vcf Social networks: bill_mcgonigle/bill.mcgonigle _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
