For Small Business Servers and home servers, one thing becomes apparent, the need to use raid with large data sets. Raid 1 and software mirroring technologies like Windows Drive Extender are too cost ineffective for large storage arrays. For example, if one has 1 TB of storage need and uses one of these mirroring redundancy option, they need 1TB extra storage for a complete backup. Likewise, if an administrator uses four 1TB drives for data storage, then another four 1TB drives would be needed for redundancy.

There are many ways to do Raid 5, but generally the best practice way is to use a dedicated Raid controller. This is for several reasons. One, the onboard cache of most controllers and the battery back up that protects that data is essential for providing exceptional performance. Raid controllers normally cost several hundred dollars for 8 port versions.

The controllers are not bad, they just support a maximum of eight drives without using expanders are fairly tall for smaller servers, and do not support some advanced features, notably Raid 6. See here for the fix. This is not an issue as much as it is a design feature.

As was previously mentioned, these are not the newest cards on the block. Finally, the IOP requires that it has decent airflow as it gets hot under normal operation. Numerous guides are available for attaching heatsinks and fans to the IOP processor. Just make sure there is a heatsink and airflow over the heatsink can be accomplished by using a case fan and the IOP should stay cool. B5 and B6 need to be covered by electrical tape, non-conductive sealant, or non-metallic nail polish.

If, after making these modifications, the server or PC in question does not boot, a very likely issue is that the manual disabling of the B5 and B6 pins had collateral damage.

Make sure to not interfere with the PCIe slot when doing this upgrade. A bad result may be not waiting long enough for the sealant to dry and damage occurring to the PCIe slot when installing. A nice feature about these cards is that drivers are supported by Dell, meaning that one can easily find Windows XP, Vista 32 and Vista 64 drivers. See Overclock. Please see this link for some benchmarks using eight 1. For simple file serving, backup usage, and media streaming, this means that the array can saturate two onboard network cards and still not be the bottleneck in reads and writes to and from the server.

Overview View all the pages Comments. Page Press to view the next virtual disk. S ee the table above to view descriptions of each virtual disk property. From the Adapter List, press to exit. In addition, a similar exit screen appears when you exit most other screens, and it can be used to save settings. The next screen shows a list of disks that can be added to a virtual disk. As disks are added, the Virtual Disk Size field changes to reflect the size of the new virtual disk.

The Activate Mirror option allows you to reactivate an inactive virtual disk that has been added to a system.

This option is only available when the selected virtual disk is currently inactive. After a pause, the virtual disk will become active See your system documentation for more information.

General Problems Table Ensure that the boot disk is a ttached to the controller at the lowest ID and check the controller and the physical disk boot order in the system BIOS. NOTE: See your system documenta tion for information about boot device selection.

Physical disk is not enumerated during POST.
