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.

MM isn't the "official" cable dell uses for the r as usually there is an a and a b cable but I've used it plenty of times without issue, it also fits the r Ordered the integrated version on amazon, with the cables and battery. The battery cable and battery will be identical though. You're going to need two of those cables as well. T is right that you need a different set of cables but the ones linked are for the 2. Perc 6i H The H the others were describing would only be supported on the following generation of servers, not the T You're going to need to make sure you get the integrated version, an xxfvx or cnxvv. The H has an integrated version, which goes into the slot on the motherboard just behind the harddrive bays near the power supply, mid motherboard, the other version goes into the PCIe slot at the back and then there is a 3rd version, so if your Perc6 is "integrated" then you need to get an H integrated model as well, you could get a PCIe version but may as well keep the PCIe slots open if you can. The server has the hot swap backplane that the drives just plug into via bays on front. Veeam backup error vddk async operation error 2.writing a letter of complaint to school.
