This is for a desktop support 2 position

I can't say that means much of anything to me. If you could post the context (surrounding info in the description) you'll get better responses.

Sure, here it is

Please read description carefully and notes below on skillset required Required Qualifications • Bachelor's degree or equivalent experience in IT. • 2+ years of progressive experience in 2nd Level or Tier 2 support in HW, network, and log level application support capacity. • Extensive understanding of Windows systems setup, configuration, diagnostics, concepts, and comfortable on a dos command line. • Demonstrated experience in UNIX/Linux system environments; installation, configuration, log troubleshooting. • Scripting experience, specifically with Ruby/Perl and shell scripting language to automate existing and workloads and routine system admin tasks. • In-depth knowledge of TCP/IP, SSH, SCP, LDAP and other core technologies such as NTP, FCIP, iSCSI, SAN, NAS etc. • Must be able to determine when a server or remote system is in a "distressed" state, e.g. network performing badly, short of RAM, overloaded CPU, overloaded I/O subsystem.

It sounds like a jr sys admin more then a desktop level 2 or a combined entry level sys admin

Yes, I vote this. I think the A+ manuals also make this comparison.

Examining and Tuning Disk Performance

From the first link:

PhysicalDisk\Disk TimeThreshold: Greater than 50 percent, it represents an I/O bottleneck
Significance: Represents the percentage of elapsed time that the selected disk drive was busy servicing read or write requests.

Great links btw, I was wrong!
