Roadmap

Timeline

2007 March - OpenSSI-1.9 port to base kernel 2.6.11.

2007 September/October - OpenSSI-1.9.3 for Debian Sarge.
2007 November - OpenSSI-2.0.0pre1 for Fedora Core 3 - CFS bug fixes, add ability to migrate active filesystems for load balancing.
2007 December - OpenSSI-2.0.0pre2 for Fedora Core 3 - bug fixes for VPROC, HA-LVS, CFS and disabled 4K stacks.
2007 December - OpenSSI-2.0.0pre2 for CentOS 4 smp and hugemem 64GB. (completed, not released)

2008 March - OpenSSI-1.9 port to kernel-2.6.18. (**partially completed in SVN**)
2008 May - Unofficial OpenSSI-1.9 port to kernel-2.6.12 for Debian Etch.
2008 August - 2.0.0pre release number reserved for base kernel-2.6.16 or higher for OpenSSI stable.
2008 October - Preview of OpenSSI-1.9.6 (aka. 2.0.0pre3) - kernel bug fixes and performance improvements to VPROC, CFS, and PROCFS. (in CVS)

2009 Q1 - OpenSSI-1.9.6 for CentOS 4 - more kernel bug fixes, performance; re-enable CFS buffered I/O (**in testing**)
2009 Q1 - OpenSSI-1.9.6 for Debian Etch(?) (**in testing**)

Milestone - OpenSSI-2.0 IA32 stable on base kernel-2.6.
Milestone - OpenSSI-2.0 x86_64 stable on base kernel-2.6.
Milestone - OpenSSI-2.0 on base kernel-2.6.16.y stable. (under review)
Milestone - OpenSSI-2.x virtualization; able to migrate virtual machines into OpenSSI.

TBD - OpenSSI-1.9 port to base kernel-2.6.16.y stable. (on hold)
TBD - OpenSSI-1.2.3 for Fedora Core 2. (cancelled)
TBD - OpenSSI-1.9 Lustre support (Note: GFS2/DLM included in kernel-2.6.19).
TBD - Discuss consolidate to Debian. (But OpenSSI download statistics indicate Fedora / Red Hat more popular.)
TBD - OpenSSI-2.0-2.6.x port OpenSSI-2.0 to latest base kernel-2.6.x. (open)
TBD - OpenSSI-3.0 Process Management Hooks on base kernel-2.6.16.y. (open)
TBD - PetaScale OpenSSI tuning to support thousands of compute nodes. (open)

Redo website. Boring website is an oxymoron. (New website coming soon.)
Detailed comparison matrix versus other SSI / Non-SSI clustering available.
Use cases where OpenSSI excels versus other Linux SSI projects.
Pictures. Non-technical write-up of OpenSSI features for English speakers. Big pictures please. See linuxvirtualserver.org for picture examples.
Performance numbers. Track millions of simultaneous connections with HA-LVS, pull some number crunching numbers from Mosix(? may differ), pull some numbers from MySQL clusters, OpenSSI serves tens of millions of hits per day, etc.
Commercial Support or Support Provider options. More than one person asked about this already.

Support 64 bit platforms - AMD64, EMT64. (There is code for IA64 in CVS.)
XEN support for the Red Hat / Fedora.
Define integration tests.
OpenGFS support for development version (kernel-2.6); include cluster LVM2.
Look into interfacing OpenGFS's quorum management into OpenSSI for CLMS quorum. ci-linux interface with CMAN/configfs might overlap with this task.
Development version to finish porting the new ipvsadm options to ha-lvs cvip.conf.
Reduce process migration overhead by optionally migrating only active data segments - may have availability ramifications though. See paper presented by Kerrighed team.
Address performance of clusterwide memory sharing talked about in Kerrighed paper. (DSM takes away high-availability...)
Finish user documentation.
Finish developer documentation.
Process pairs and checkpointing.
TCP socket migration.
Globalview top command to optionally show cluster (aggregate) memory / cpu statistics.
Update FC3 base packages to latest - ~~e2fsprogs~~, initscripts, nfs-utils, pam, procps, sudo, udev, util-linux.
Quota support for CFS.
Verify Lustre support for 1.9.x.

Technology we might be interested in integrating into OpenSSI.
