I have a RX1330M1/LFF/HOT with 2 WD 1TB B.C. yellow sata hd in raid 1 configuration on LSI embedded MegaRAID controller. The write performance of the volume are very poor the writing tail is often full.
Sorry I have some questions:
If I active the "disk cache mode" I have an improvement of the performance ?
Can I do this (on/off the cache mode) in production environment without any problem ?
Have the embedded megaraid a backup battery in caso of power failure ?
If No the power failure with cache mode active what does ?
