Last year I shopped around for a quad-core 8GB box with ECC RAM. The RAM itself is not much more expensive, the problem is CPU/chipset support. I went with an AMD Phenom - I think that with Intel CPUs, you only get ECC in the Xeon server line.
(Note that besides bunging in the ECC RAM DIMMs, you may have to turn on ECC support in the BIOS.)
Just using increasing amounts of RAM, storage and bandwidth, without adding data-integrity checks, is really asking for trouble ...
- lutorm 17y agoThe increasing storage problem applies to hard drives, too, and the increasing need for something like RAID6 over RAID5.
- derobert 17y agoNeither RAID5 nor RAID6 give you integrity checks. Each block of data is only read from /one/ disk, unless that disk is failed (in which case parity & data is read from the remaining disks to calculate that block). If the disk recognizes the sector as bad (through its own, internal redundancy checks), then (depending on RAID implementation) either that one block will be read from parity or the entire disk will be dropped from the array. But, if the disk silently corrupts data, RAID5/6 will not protect you. In fact, it makes the problem worse; silent corruption is more likely the more disks you have)
