my client has 2 xserves, one of which is connected via an atto r680 pci card to a la cie 12big RAID array. given that the xserves are now long in the tooth, and Apple no longer makes a box that will take the pci card, does anyone have any thoughts as to where to go next? Client is v loathe to abandon the relatively recent investment in the RAID and card. i imagine that the new mac pro will be terrifyingly expensive, and it cannot use the atto card. so where next? anyone ever successfully virtualized os x server? thought on a postcard please!!
