Techopedia Explains RAID 6E

The addition of a hot spare drive enables increased performance and reliability by replacing a failed drive.. In the beginning, spare drive could only be used per array, not with other RAID arrays. However, more recent advances in SAN architecture and controller design have made it possible for several arrays to share hot spares.
