Yesterday Oracle released an overhaul of their volume server (x86) line. The flagship X4800 looks looks really impressive for an x86 system, eight sockets, up to 1TB memory and hot swappable IO. Equipped with Xeon X7560 CPUs it will fully loaded have 64 cores and a total of 128 thread. All PCI boards and power supplies are hot-pluggable and the four CPU modules look fairly hot-pluggable. One can wounder if support for CPU hot-plug come later future since Intel 7500 was the aim for CPU and Memory hot-plug discussed here earlier.
