今回は今まで利用していたRAID構成を壊して普段使わないRAIDモードを試してみました。本当は仮想OSを稼働させるDISKをどれにしようか考えていたんだけど、やはり金銭的にRAID５構成を再構築するのが良いかな・・・・とか・・・。
とりあえず3つのRAID構成でデータを取ってみたので参考になる部分あればうれしいです。
構成
ホストOS ： Windows Server 2008 Datacenter Edition x64
RAIDカード ： 3ware 9650SE
HDD ： Hitachi HDT725050VLA360 SATA 465.76 GB × 4台
RAID5(空き容量全体の約2割程度)
