i am facing 2 choices i believe after checking out various
ways of providing effective hard drive speed/redundancy for a
DB. it seems RAID 10 is the best way to go if you can afford
the space lost compared to RAID5. so - i am looking for any
recommendations regarding these 2 IDE based methods:
1. vinum RAID10 (one drive per IDE controller).
* downside seems to be lack of hot-swappability.
* system needs to come down and be serviced to make a swap.
* vinum maybe slower than a 2 or 4 drive external solution
2. Promise external IDE RAID storage with SCSI interface
capable of 4 IDE drive each on their own controller
(UltraTrak100) http://www.promise.com
* expensive ($1500 or so)
* onboard CPU (i dunno how fast this would make RAID5 on it)
* hotswappable IDE interface (ie - user maintainable)
this will be a production machine whose 24/7 reliability is critical.
please reply off the list as well as i am not subscribed.
i am mainly concerned with A) SPEED B) RELIABILITY/MAINTAINABILITY
thank you.
