Does anyone know how to determine the amount of LDOMS one can create on a T5220 with 1 Quad core running Sybase 12.5. I understand there are many factors in the type of database but in general are there best practices or guidelines to follow? Is there much overhead for the Control, service domains?
You have posted this to the wrong forum :)
However, best practice recommendations for LDoms are that you should create domains using whole cores, so in your case that would mean 3 guests plus the control domain.
Of course your mileage may vary and you could go higher. The physical max no of domains on your system would be one per Vcpu - so 4 cores x 8 threads = 32.
This thread has been moved from its original Solaris Zones forum,
to the CMT Servers General Discussion forum.
CMT systems are the T-series products.
They can be configured with true LDOMs.
Additionally, yours is a hardware configuration question, while zones are a software construct.
