By using a hamming code in RAID level 2
system, these memory systems will provide recovery from failed components. By
default, data is stripped in such a way that there is a placement of each
sequential bits with each corresponding bit seeing the calculations of hamming
codes. Thus, when the booting process starts, any firmware failure is catered
for. Raid 2 level systems would be straightforward and simple as compared to
other RAID levels and would also provide high performance and data transfer. It
is beneficial to a University payroll in that it would be able to detect errors
and make corrections
The disadvantages of RAID level 2 are
that it is sometimes very expensive and might require difficult configurations
to implement. All drives must also be kept in a synchronized condition.
An
alternative RAID system suggestion would be RAID 5. It is a good combination of
both RAIDS 0 which is very fast and RAID 1 which is very reliable. It is the
most common method used these days since it achieves a good balance between availability
and performance. RAID 10 is also a good suggestion.
