(RBD) via librbd without the need to use the kernel rbd driver. This
ioengine defines engine specific options.
.TP
+.B http
+I/O engine supporting GET/PUT requests over HTTP(S) with libcurl to
+a WebDAV or S3 endpoint. This ioengine defines engine specific options.
+
+This engine only supports direct IO of iodepth=1; you need to scale this
+via numjobs. blocksize defines the size of the objects to be created.
+
+TRIM is translated to object deletion.
+.TP
.B gfapi
Using GlusterFS libgfapi sync interface to direct access to
GlusterFS volumes without having to go through FUSE. This ioengine
Read and write using mmap I/O to a file on a filesystem
mounted with DAX on a persistent memory device through the PMDK
libpmem library.
+.TP
+.B ime_psync
+Synchronous read and write using DDN's Infinite Memory Engine (IME). This
+engine is very basic and issues calls to IME whenever an IO is queued.
+.TP
+.B ime_psyncv
+Synchronous read and write using DDN's Infinite Memory Engine (IME). This
+engine uses iovecs and will try to stack as much IOs as possible (if the IOs
+are "contiguous" and the IO depth is not exceeded) before issuing a call to IME.
+.TP
+.B ime_aio
+Asynchronous read and write using DDN's Infinite Memory Engine (IME). This
+engine will try to stack as much IOs as possible by creating requests for IME.
+FIO will then decide when to commit these requests.
.SS "I/O engine specific parameters"
In addition, there are some parameters which are only valid when a specific
\fBioengine\fR is in use. These are used identically to normal parameters,
Poll store instead of waiting for completion. Usually this provides better
throughput at cost of higher(up to 100%) CPU utilization.
.TP
+.BI (http)http_host \fR=\fPstr
+Hostname to connect to. For S3, this could be the bucket name. Default
+is \fBlocalhost\fR
+.TP
+.BI (http)http_user \fR=\fPstr
+Username for HTTP authentication.
+.TP
+.BI (http)http_pass \fR=\fPstr
+Password for HTTP authentication.
+.TP
+.BI (http)https \fR=\fPstr
+Whether to use HTTPS instead of plain HTTP. \fRon\fP enables HTTPS;
+\fRinsecure\fP will enable HTTPS, but disable SSL peer verification (use
+with caution!). Default is \fBoff\fR.
+.TP
+.BI (http)http_mode \fR=\fPstr
+Which HTTP access mode to use: webdav, swift, or s3. Default is
+\fBwebdav\fR.
+.TP
+.BI (http)http_s3_region \fR=\fPstr
+The S3 region/zone to include in the request. Default is \fBus-east-1\fR.
+.TP
+.BI (http)http_s3_key \fR=\fPstr
+The S3 secret key.
+.TP
+.BI (http)http_s3_keyid \fR=\fPstr
+The S3 key/access id.
+.TP
+.BI (http)http_swift_auth_token \fR=\fPstr
+The Swift auth token. See the example configuration file on how to
+retrieve this.
+.TP
+.BI (http)http_verbose \fR=\fPint
+Enable verbose requests from libcurl. Useful for debugging. 1 turns on
+verbose logging from libcurl, 2 additionally enables HTTP IO tracing.
+Default is \fB0\fR
+.TP
.BI (mtd)skip_bad \fR=\fPbool
Skip operations against known bad blocks.
.TP
\fBblktrace\fR\|(8) for how to capture such logging data. For blktrace
replay, the file needs to be turned into a blkparse binary data file first
(`blkparse <device> \-o /dev/null \-d file_for_fio.bin').
+You can specify a number of files by separating the names with a ':' character.
+See the \fBfilename\fR option for information on how to escape ':' and '\'
+characters within the file names. These files will be sequentially assigned to
+job clones created by \fBnumjobs\fR.

.BI read_iolog_chunked \fR=\fPbool
Determines how iolog is read. If false (default) entire \fBread_iolog\fR will
