Cgroup and Package Resource Limits

Dear All,

I need some help regarding the CWP's Cgroup and Package Limit Settings.  Please excuse me if this inquiry seems to look noobs :p

In cPanel shared hosting they have the following resource limits:

- Disk Space Quota
- Bandwidth Quota
- CPU
- Entry Processes
- Physical Memory Usage
- IOPS
- I/O Usage
- Number of Processes


CWP have the following resource limits:

Via Package
- Disk Space Quota
- Bandwidth Quota
- NPROC
- Apache NPROC
- Nofile/Open Files

Via Cgroups
- CPU
- Memory
- Disk I/O


So based on the definition of each item, I matched the cPanel items to the CWP items as follows:
      

---- cPanel ----		---- CWP ----
Disk Space Quota	=	Disk Space Quota
Bandwidth Quota	=	Bandwidth Quota
CPU	=	CPU
Entry Processes	=	Apache NPROC
Physical Memory Usage	=	Memory
IOPS	=	?
I/O Usage	=	Disk I/O
Number of Processes	=	NPROC
?	=	Nofile/Openfiles

Referring to the table above, the counterpart/equivalent for both IOPS and Nofile/Open Files are missing.

Need your help in identifying those two, thank you. 


Kind regards
