Re: new cume out for 7.1

True that, if you can do them on one partition for many tenants that is 
a possibility. But you have to coordinate times and releases with them 
then so negapoints for that! And if they use any tools (the DBUs or 
Gumbos or BVSTools of the world) you get to coordinate some of that as well.

IMHO multi-tenant is great if you are doing SAAS because everyone would 
have the same toolset, or at least the same toolset AVAILABLE. With 
multi-tenant that are using different software that quickly becomes a 
quagmire. "I need QSECOFR Password..." (oh oh)

With network based imaged catalogs it's a matter of VARY ON a device and 
let the PTFs fly. No copying, no loading, no verifying, just PTFing. 
Yeah there are backups and what not of course but if the partition is 
small, they're quick!

Partitions can go down to 0.05 of a processor today and for 5 users 
honestly that is plenty, I think 600 CPW!!  Disk is still going to be 
around 70GB minimum with a 35GB Load Source for i 7.2 and up. But we 
often skirt the recommended 6 drive minimum when there are super low 
users like this. Just not enough total I/O to care.

And again with low users 2GB of memory could end up being just fine. 
Sure an IPL is a little slower but we do those so rarely these days it 
doesn't matter. Very likely a customer on an old Power5 with 5 users 
might only have 512M or 1G today.
