According to this article, the write claims Xen will catch up to VMware by 2008.
The supporting argument is stated as:
“The features that Wolf expects Xen players to add to their suites include comprehensive live migration capabilities (i.e., “VMotion” in VMware parlance), better SAN (storage area network) integration and more sophisticated backup APIs.”
VMotion is a significant piece of technology that VMware has had available and running in production environments for the past year. By the time Xen introduces it, VMware will have undoubtedly introduced something else just as new and exciting, leaving Xen to catch up once again.
Better SAN? VMware boasts support for SAN, NAS, and iSCSI. What could be better than storage over IP with an existing network card? 🙂
BackupAPI’s – Umm, VMware Consolidated Backup is pretty sweet today.
I’m not trying to purport that VMware is the greatest virtualization product and can never be dethroned, but the arguments presented in the article are not what I would use to stand upon. VMware has a nice track record of coming out with new things every year that work very well and seem to seamlessly integrate into whatever environment you’ve created. I also can’t claim to be a Xen expert. I have read some good things about the product but I still feel the product is at least a few iterations behind that of VMware’s offerings.
