Historical Section
The Historical Section includes all traces that are older than 10 years.
Categories
The I/O Trace Data files have been segregated into several broad categories. These categories are typically, although not exclusively, defined by the measurement point at which the respective I/O trace was taken.
The categories (or types) of I/O traces include:
- Show all
-
Application Traces [This category is currently empty]
Application Traces record calls made by a specific application. -
Block I/O Traces
Block I/O Traces typically include block level (e.g., at the logical volume manager, disk driver, etc. level) and block protocol (e.g., SCSI, ATA, Fibre Channel) traces. -
NFS Traces
Network File System Traces are typically those for NFS and CIFS and which reflect the protocol used by such network file systems. -
Parallel Traces
Parallel traces, generally taken from supercomputers, record the system calls made by multiple computers running in parallel. -
SSSI WIOCP Metrics [This category is currently empty]
SSSI WIOCP, the SNIA Solid State Storage Initiative (SSSI) Workload I/O Capture Program (WIOCP), collects already-summarized empirical metrics separately for both monitored devices and processes/applications. More information about the SSSI WIOCP can be found in the SSSI WIOCP FAQ and the 'Introduction to the SSSI WIOCP I/O Metrics' whitepaper. -
Static Snapshots
Static Snapshots are traces taken statically of a file system rather than of system calls. -
System Call Traces
System Call I/O Traces typically reflect operating system calls to the file system.
