You can also download prebuilt SCST modules for - Scientific Linux CERN 5 (RHEL5-based), - Ubuntu, - Debian, - Alpine Linux and - openSUSE - (spec).

- -

Since recently, SCST allows to build Debian packages using "make dpkg" command. Previous instructions how to build - SCST DKMS package for Debian-based systemd-enabled Linuxes you can find - here.

+

Debian packages can be built by running + "make dpkg". RPMs can be built by running + "make RPM".

As a complete SCST-based system you can try Enterprise Storage OS (ESOS).

Possible SCST extensions and improvements

-

Asynchronous FILEIO in scst_vdisk handler

- -

At the moment scst_vdisk handler for FILEIO uses regular synchronous read/write() calls - and makes deep queue depth by using multiple threads. This is not too high performance - model of operations. It would be much better to use asynchronous I/O with not blocking - I/O calls.

- -

In the user space native AIO is available for many years, but only very recently ability to - use it was added in the kernel. Changing FILEIO to use the new interface should significantly - (up to multiple times) increase performance of FILEIO devices.

- -

Support for O_DIRECT in scst_vdisk handler

- -

At the moment, scst_vdisk handler doesn't support O_DIRECT option and possibility to set it - was disabled. This limitation caused by Linux kernel expectation that memory supplied to - read() and write() functions with O_DIRECT flag is mapped to some user space application. - Having O_DIRECT together with above asynchronous FILEIO would be another significant - performance boost for modern solid state devices. For instance, in fio utility - direct AIO long ago proven to be the fastest way to benchmark storage.

- -

It is relatively easy to remove that limitation. Function dio_refill_pages() - should be modified to check before calling get_user_pages() if current->mm is not NULL. - If it is NULL, then, instead of calling get_user_pages(), dio->pages should be filled - by pages, taken directly from dio->curr_user_address. Each such page should be referenced - by page_cache_get(). That's all.
