Upgrading a 3-disk RAID5 with an extra HDU - is data integrity retained?
Posted on 2013-05-27
I have a client with a HP Prolaint with a RAID5 configuration with 3 146GB disks. They have some problems with data usage and they want to expand the storage. Now someone has advised them to add one 146GB harddisk, and they claim that the data integrity will not be changed.
The client assumes that the 4th harddisk will be aded to the RAID5 config. If this can be done, he will not have a nett storage of 146GB but less, am I right? And is this a save sollution?
Thnx for your imput.
