The query turns into no matter if you need to supply that strength with fewer, beefier servers; or, use many less-powerful servers. I lean towards utilizing extra servers. ߜ professionals • The extra servers you've, the reduce the share of total processing energy you lose if one server dies. • you could unfolded the price of paying for over an extended time period by way of development your method modularly as you wish extra energy. • you could simply use rack mount or blade structures with the “more servers” technique. when you opt for a blade-based method, it's possible you'll now not have as many I/O ports as you will have. simply ensure that if you want twin HBAs and 4 NICs consistent with server, your blade method will let it. ߜ Cons • One power draw back to the “more server” method is technological obsolescence.
