Hello Experts,

We have a high-end EMC storage configured with RAID0+1 and a high-end HP-UNIX server in which the LVM slices from the storage device will be mounted. I need the following clarifications:

1. What is the maximum size which can be assigned to a single-LVM mount point? Any threshold? Our requirement is around 200 GB.
   
2. How many mount points can be created? Is creating more mount points will affect the server performance?

3. What are the considerations to achieve sustained through put of 50MB /Sec. We expect the Storage should give a sustained through put of 50MB /Sec between Application and Storage, after all necessary disk layout/configuration changes.


Thanks in advance....

Ashok

PS: Please let me know if you have anyother suggestions also.

50MB/sec is no problem at all on a CLARiiON - an 8 disc RAID 1/0 set will achieve this with ease without any special tuning. A RAID 5 set would also produce that sort of performance for reads with ease.

>1. What is the maximum size which can be assigned to a single-LVM mount point? Any threshold? Our requirement is around 200 GB
According to http://en.wikipedia.org/wiki/HP-UX, 32TB per file system in the latest release.

But this document answers all your questions around LVM: http://docs.hp.com/en/6054/Limits_wp.htm

I'd strongly recommend that also you review this document: http://www.emc.com/techlib/abstract.jsp?id=1733&c=US&l=en

It contains lots of good information around CLARiiON performance and performance optimisation.
