But if another one hard disk fails then we lose all data, so we have double protection here. If another 1 disk fail before we have a chance to replace the first broken one then we still have all data but with performance degradation. If one disk FAIL on RAID 5 (data ) then the online spare disk will kick in and system running without any performance degradation. If one disk fails on RAID1 (operating system) then we have other disks that will run without any performance degradation. So we have 2.5 TB capacity when using RAID combination above, but if we don’t use any RAID we will have 8x500GB = 4TBīecause this is a server that serves as a file server for about 300 busy peoples don’t afford to have long downtime. RAID 5 (5 disk) + 1 disk online spare = 2TB. With above RAID configuration, our effective data volume becomes: We have 8 x 500GB SATA hard drives and we configured it 2 x 500GB RAID1 (mirroring) for Operating system, 5x 500GB configured as RAID5 and 1x 500GB configured as hot online spare.
It depends on how many disks you have and how you want it to configure.
Setup Windows Server 2008 Standard edition. Below is the picture of error when I use lifecycle controller program to install Microsoft Windows Server 2008 standard edition using option Microsoft Windows Server 2008 R2 with SP1:
Microsoft Windows Server 2008 R2 with SP1Īlthough Microsoft Windows Server 2008 and Microsoft Windows Server 2008 R2 with SP1 seems the same it’s totally different, the driver also different so we cannot choose option Microsoft Windows Server 2008 R2 with SP1 to install Microsoft Windows Server 2008 standard edition.īefore I succeed installing Windows Server 2008 standard I tried to use option Microsoft Windows Server 2008 R2 with SP1 and it doesn’t work.
