Xen & VxVM
The guys over at XenSource have pulled a master stoke, they have announced they will be integrating VxVM & VxFS into their Enterprise product . I'm a VMWARE VCP and it always amazed me that the VMWARE ESX didn't support fibre multipathing with load balancing. I've always taken multipathing for granted with Veritas (Symantec) VxVM DMP ( a must with Photons ) and latter MPXIO in Solaris . I'm sure VMWARE will add EMC PowerPath soon to push along those CLARiiON. Remember you can get Veritas Volume manager for free, check this blog post .
