IOKIT is the file type of a file output from Dell performance analysis tool called DPACK.

It has an XML header and after the XML, there is binary data.

The process is that the customer runs the Dpack tool on their SAN for a given period of time. The tool records the performance of the SAN for a given period in terms of IOPS and data transferred per second.

Then the data file output is manually uploaded to Dell and a sales rep sends you back the graph analysis.

What we want is to decode the dpack binary so that we do our own graphs.

So its a puzzle...

The inputs to the puzzle are:

- The are two devices recorded => 2 SAN's.

- The file given to dell ([url removed, login to view])

- The graphical outputs returned by dell ([url removed, login to view] containing SAN1+SAN2 from the below across the entire time range, and [url removed, login to view] containing SAN1+SAN2 for one particular day)

- The duration of the recording (7 days)

The outputs are to be:

- The series of values observed in the Dell graph in a csv file:

- SAN1+SAN2

- Data read per second (MB/sec) of the recording period.

- Data written per second (MB/sec) of the recording period.

- Data read per second (IO's/sec) of the recording period.

- Data written per second (IO's/sec) of the recording period.

What we have learned so far:

- The file does not appear to be compressed or encrypted in any way

Any takers?
