The MB Battery-backed controller should fit your needs very well. Which option would you recommend for my scenario for best performance while not spending unnecessarily? AX1 NV cache is a better technology, but unneeded here. They know their hardware better than anyone. AX1 AX1 1, 2 2 gold badges 23 23 silver badges 39 39 bronze badges.

When using SQL you'll want to disable write-back cache regardless of the controller to ensure writes get to disk. For web sites using slowly changing data sources then caching in IIS will give you the best performance. The RAID 1 array is going to be the bottleneck although some cache may help a little. If you trust your power environment very well, a battery-backed cache will save you some money versus the non-volatile cache option. The amount of data you're slinging around isn't that large to multiple internal connectors is not that important. This will survive a power-outage for a lot longer than a battery-backed cache. A super-capacitor on the card has enough juice to commit the cache to flash-memory in case of sudden power loss. The battery is there in case of power loss, the battery supplies voltage to the cache-RAM. It caches writes in this storage to re-order them for more efficient usage of your disk. I don't want to burn money by buying something for no reason, but at the same time ensure that I'm getting what I need. I don't quite understand the significance of differences between the various Dell RAID controllers for my scenario, it would be great if you guys could help me choosing the right one.

Ships with cache off, they want you to put on UPS, then enable cache to prevent data loss of data in cache if power outage. Only RAID levels 0,1, and System seems to be running well at RAID 10 so far. So RAID 10 is your choice, as others above suggested. Raid 5 with this controller if it would be supported, but seems it is not in H version would be terrible idea. I had looked for a battery option for this and have not been able to put together the correct part s needing to add the battery back up option to the H It will be covering a small poweredge T tower server, a small linksys or netgear router and 8 port switch. I would buy the battery back for the H if possible, go with a solid UPS if not.
#DELL PERC H200 VS H200 INTEGRATED IT MODE WINDOWS#
Windows lacks all the functionality that you desire in the H, so you would gain nothing but lose reliability and ease of use. If I enable write cache, is there also increased chance of corruption if the OS crashes? How does the performance compare to the H with and without write cache enable? Is it more or less reliable? What happens if a drive fails? The server will be running SBS and has 4 drives. This is due to the fact that it lacks a backup battery. I have read that the H ships with write cache disabled causing severe performance issues.
