Something that caught their attention though was that
the number of I/Os on the mainframe were about 30 times (not percent)
higher than on Intel. They said they'd used an Oracle tool to

this. Not knowing anything about Oracle's tools in this arena, I have

My initial assumption about this is:
On Intel/AMD, they are using 512 byte blocks. Standard PC file system...right?
And even though we are using the same 512 byte blocks under the RAID covers, we
