XOSAN is a paid option? If yes - good luck, both HALizard and Starwind VSA for Xen are (will be?) free. if XOSAN is free - very cool!
I don't think one can compare XOA + XOSAN to Starwind VSA or HALizard.
First, XOSAN is not available as a standalone product.
Second, XOA + XOSAN offer a lot of things that Starwind & HAL don't. It doesn't make XOA/XOSAN better just different. -
@KOOLER the reason I say that support is only smart for consumers is that if software is free (open source) there doesn't have to be a massive investment in that purchase.
But paying for support, because 99.999% of everyone is not an expert on said solution, really truly does need support.
Even if it's only an hour a month. That times N is a very large customer base.

XO can also include XOSAN, it's something I was working on figuring out today. But has the major issue of being completely unsupported. I'd doubt if @olivier and company would even answer any questions about it. And with just reason.
It has to be supported by the people that developed it.

This hasn't been announced yet.

Which I was working on figuring out today for anyone who's willing to go that route.
I would suggest an XOA trial instead so that your testing is meaningful while XOSAN is in beta.

Hi there,
XOSAN beta is meant to be done on XOA only because it uses mechanism related to xen-orchestra.com (you need a valid account there, with a valid token). So it's not possible to try XOSAN via XO on the sources.
It's still in a really early phase right now, so before going further we'll validate all the Phases explained in the blog post.
About the StarWind thing, I don't know the product at all, but on our side it's:
- XenServer only
- Thin provisioned
- Pool wide, ie working from 2 nodes up to 16 (well in theory more, but it's pool-wide not across pools)
- Uses Duplication/Triplication but also Disperse mode, depending of your need
- Auto heal (when a host/node is coming back online, it fetches all the missing data)
- Easy install/deploy (thanks to XOA)
- And more (basically, everything you can do with GlusterFS but "in a box", so think about HDD+SSD caching, complex disks usage to avoid any hardware RAID etc.)
-
Hope to start playing around in the next day or so!
-
Just made some benchmarks recently: https://xen-orchestra.com/blog/new-xosan-benchmarks/
-
@olivier Will the community members get to test XOSAN?
-
It's available in XOA Free, so you can test it without restrictions
-
@olivier So no lol.
-
It's completely free and easy to use
XOSAN deployement process is complex, rely on various bricks and linked to xen-orchesra.com, so that would have require a lot of effort to make it available directly from the sources in a usable way.But if you want to do it yourself, it's also possible:
- create a VM in each host of your pool you want to have in the cluster
- install gluster server in each, create the cluster
- install gluster client in XS
- modify the file SM driver into XenServer to fit with Gluster
- restart the toolstack
- mount it
This way, you could also bench it
-
Not a published blog post (still in draft) but here is some bench done, please follow this link and keep it for yourself
We hope to make it for the end of the month (phase II) with a robust health status and flexibility (XOSAN full diagnostic, allow to replace in one click any faulty node, and everything auto heal itself).
Also, we'll try to release the Gluster driver in Open Source for those who want to connect XenServer to an existing Gluster or create their own XOSAN manually.
XOSAN will be an extra product of Xen Orchestra (but you can purchase even in XOA Free), including the turnkey side (and believe me it's not trivial) with full diag status and health + flexibility, including pro support on it obviously.
We'll try to make a Phase III before the official release, with tiering capabilities (HDD + SSD cache to get best of both world).
We started to create the official doc here: https://xen-orchestra.com/docs/xosan.html
Remember the goals of XOSAN:
- protect your data thanks to replication of data on multiple (from 2 to 16) hosts
- provide XenServer high availability without buying a NAS or a SAN
- give you flexibility to grow your storage by adding new nodes
- work on all kind of hardware, from HDDs to SSDs
- fully monitored solution
-
@olivier Very Impressed! Nice work
-
@olivier Very nice numbers there, and I'm excited you're looking to release XOSAN to the community!
-
@dustinb3403 It won't be XOSAN to the community. XOSAN is like XOA, a turnkey packaged solution.
You'll be able to mount a gluster volume when we'll open the Gluster driver (which allows to create a SR of Gluster type in short). Then you can do whatever you want with that, but you'll need to monitor it yourself, and understand how Gluster works. Something you won't require by using XOSAN
Also a trial version of XOSAN will be available for people who want to test it and bench it quickly (literally in few clicks)
-
@olivier Two comments, these links don't work
Lastly, if you are converting your native language to English have you considered a translation or proofing service?

- Doc is not completed because the product isn't. Consider it as a draft.
- Blog post is still a draft
