B.
S824 has more cores than S822
The Power S824 (8284-42A) server is a powerful one or two socket server that ships with up
to 24 activated cores. It has the I/O configur
ation flexibility to meet
today’s growth and
tomorrow’s processing needs. This server supports two processor sockets, offering 6-core or
12-core 3.89 GHz, 8-core or 16-core 4.15 GH
z, or 24-core 3.52 GHz configurations in a
19-inch rack-mount, 4U (EIA units) drawer configuration. All the cores are active.

S822 is more appropriate for HPC (hhttp://www-03.ibm.com/systems/power/hardware/hpc/)
That’s a trick questions no?

Actually I would say D,
S822L, linux box is normally cheaper, it has up to 24 cores in 2U of the rack. S824 has up to 24 cores in 4U space, so the S822L can have double the amount of cores in one rack.

I think its B, because the max. no. of cores.
The 824L are nearly the same.

Answer is C, Question is how many cores can fit into a 19″ rack. For every 2U, you get 20 cores, so in 4U is 40 cores.
S824 4U is 24 cores.
S822 runs either AIX or Linux.
