I have a couple of questions about Data Movers in a VNX NAS environment as i have some file servers that i might want to consolidate on a VNX. Those might seem random questions, but i need to understand them in order to decide on my next action plan:
- What is the maximum number of concurrent CIFS connections to a single data mover?
- What is the maximum number of concurrent NFS connections to a single data mover?
- When would i need to add another data mover? Is it when:
- I reach the capacity limit of my data mover?
- I reach my max number of concurrent connections to a single data mover?
- If i deploy CIFS/NFS for "file shares" only (not applications like VMware or oracle), what is the typical workload profile? Sequential, Large Block, Small block..etc?
for datamover limitation you can check VNX for File release notes. You would need to add datamovers if you need additional network capacity, if you reach maximum file system count/capacity per datamover (again listed in the release notes). I typically see small block random I/O on my office shares.
Thank you dynamox for your reply.
I can see for CIFS (64,000 but tested 20,000) and NFS (64,000).
Am i looking at the right place? Does that make sense?
Yes – but these are the hard limits
Depending on what your clients are doing of course and your data mover model you need more data movers before that
