Switching to XCP-NG, want to hear your problems

@nikade No our current storage does not support nfs. but which enterprise grade-storage beside top end Netapp and Dell PowerStor really do??
The TrueNAS storage products either the physical TrueNAS hardware products from iXSystems or using TrueNAS Scale download installation on a server of your own choosing. The recent release of TrueNAS Scale 24.04.2 is likely to really do well as SR for XCP-ng. It's performance is second to none and also will protect data integrity and also can do both SCSI and NFS.

I would not compare TrueNAS to IBM, HP, Dell, Netapp,... I have never seen this as a serious storage backend for VmWare or HyperV in a mission-critical environment. And today i have to say that you find this types of environmets in all customer sizes.
TrueNAS is also way more expensive than any IBM FlashSystem

Your rather mistaken as there's a wide variety of US Fortune 500 companies and the US Government which use TrueNAS in their organisations. Additionally Vates is using a TrueNAS instance in their infrastructure!
Also you don't have to use their hardware products you can roll your own TrueNAS by installing it on a compute server originally produced by another company.

You sound a bit grumpy today @rfx77
-
@rfx77 there are several other options, alike a3 is one good agentless solution that runs xcp-ng cbt backups. XOA is allready having in beta and is focussing on getting 100%, we run our backups on cbt and it seems to work allrwsdy very good. Coalesce with cbt is almost instant.
I know Nakivo is also planning on adding xcp-ng to there solution kn the near future. -
Sorry for that but i am fighting to tune and get backup right for nearly a week now and it is hard to find a real 100% solution.
the migration from vmware gives us lots of headaces because of tight storage space and the snapshot problematic -
CBT will be helpful for you, as @rtjdamen said
-
@olivierlambert
Yes. Unfortunately i dont think that CommVault will add this feature if i request it. And from a bigger perspective where Xen is only on part of many there is no other option for us where we use it today.For smaller customers we are already evaluating XO with CBT for the VM backups + CommVault Agents in the VM (like others do with veeam)
But we are not entirely convinced that Xen will be our one-fits-all solution for our customers. maybe it will be a combination of hyperv and xenserver/xcp-ng

If you don't try asking (or requesting) CBT support of XCP-ng being added from CommVault then you won't know for sure (let alone get). They have support for CBT on other hypervisors, so thus they do have CBT support generally. Thus they just need to add support for CBT on XCP-ng (via XO) in CommVault products. Xen Orchestra has recently on XOA latest channel added CBT.
-
okay. you convinced me
i opened a support ticket with a feature request. I will keep you updated on this forum

We're using Dell Powerstore 500T and 1000T and they both support NFS, tbh everything is beond expectation. Dedup, performance and reliability is great.
Before that we were using Nexentastor which were ZFS based and they supported both iSCSI and NFS.
I guess it all comes down to your infrastructure and what you have at hand - Not everyone can afford a Powerstore. -
@nikade
We were also evaluating Dell PowerStore, ME5 (We are Dell and IBM Partners) and Infortrend but all NFS options are simply much to expensive for 90% of our cutomers. We openly discussed it with our major customers which could efford it but they opted for iSCSI and bought just more SSDs. So on new projects we do not really have that much of a problem if we are careful.On existing customer installations where we have FibreChannel and iSCSI it is different Story.
But i am glad to hear some feedback what others are using and that they are using xen in mission critical environments. often it is not clear what usecase people have and if they are talking about homelab, small non critical systems or something like Oracle VMs, ERP VMs, so serious work.
Thanks
-
That's the opposite. We have far more critical deployments than homelabbers. You can see us as an "opposite Proxmox" on this
-
@olivierlambert @john-c So i have feedback from commvault. There is an existing Request for Enhancement but no timeline or if it ever will be implemented. The CMR is 346970, for reference
To speed things up there are many more customers needed that reference to this CMR. Thats a chicken-egg problem and i dont think that thats the way to go.
But maybe vates could commmunicate with commvault directly and reference the CMR. For commvault it would be clearly heplful if they could have better numbers about how many customers use XCP-NG and what the potential is.
-
@olivierlambert thanks for this info. i also cannot not understand where all the love for proxmox comes from. and thats from someone who has his office in their neighborhood.
-
Have you tried CBT with XO before?
-
@rfx77 Proxmox exists from 2008 and built a big home labber community (which is great!). All those people are ambassadors and love using it for their lab. Having a big and vocal community doesn't mean it's deployed everywhere in the corporate world.
-
@olivierlambert i have running a XO installation which does backup a small part of our infrastructure, which works well. it is a single host with local thin-provisioned storage.
we also tried it on our main pool with iscsi storage and had mostly the same problems like others above.
we decided to wait a litte longer before we give it another try on our main production system mainly due to some hanging snapshots,...
in the future we are planning to use it as main vm-level backup solution for standalone hosts in combination with commvault agents in the vm.
our current test status i that we try to use XO as a docker container which would fit better in out existing backup infrastructure as we could easily integrate it in our linux backup appliances (see it like a linux NAS). The docker tests are running very well and we dont have any issues at the moment. even file-level-recovery is working well in this scenario.
-
So I advise to test CBT, this might solve your coalesce issues, since the snapshot will be removed a lot faster
-
@olivierlambert i do agree, from our experience cbt did solve this issues. Snapshots are removed in seconds, this was 10 to 15 minutes prior to using cbt. There is still some work to be done with cbt but it is usable at this time.
