Which Sun SPARC Servers come with preinstalled RAID controllers?
So far I've found that the SPARC and Netra T Series Servers come with an integrated RAID/disk controller with RAID 0 and 1, but I haven't found anything for the SuperCluster, the Enterprise M-series, or the x86 servers.
x86 Server- depend from ordered configuration. You can order RAID controller or not.
Enterprise M-series. Don not support RAID controller for boot-device.
SuperCluster based on servers T4-4, that have internal RAID controller, but not shure that used.
Current trend - use ZFS for boot-device. In this case Oracle recommend use ZFS-mirror pool instead internal RAID controller.
