@scottalanmiller said in XenServer 7.0 SMB SR question:
Because XS doesn't use SMB for an SR. No one does but Hyper-V. You use NFS for everyone that isn't Hyper-V.
XS 7.0 can use SMB as an SR
https://www.citrix.com/blogs/2016/05/24/xenserver-7-whats-new/
"Everyone" has always said "XS includes everything..."
Why can't I find the SMB/CIFS option (when I go to create a new SR)?
Have you or do you plan to "transition" from Hyper-V to XS?
Do you use the free or paid version of XO?
Since you've had a few months to test XS https://mangolassi.it/topic/8482/brrabill-s-field-report-with-xenserver
Can you provide some thought/feedback?
Is it what you expected, better, worse etc?

@aaronstuder said in Hyper-V - 3 VM migrations to new host:
@JaredBusch I was wondering if you could do that
My google skills must be lacking....
I've done it with my FreePBX install while on a call. I had about 15 seconds of silence when the network switched, but the call never dropped.
Using Hyper-V failover?
Yep, I've also done this before with Hyper-V failover, 3CX was my PBX. I think I even recorded this on YouTube

@scottalanmiller said in XenServer 7: best practice: noob question:
Yes, RAID 10 is still faster and with lower latency. But with a good RAID controller, this is trivial and the cost doesn't make it make sense. Even with RAID 5 you can easily overrun your controller so there is no reason to spend money where the bottleneck doesn't exist.
What is your preferred RAID controller? Is the LSI family good enough?
For optimum performance in a RAID5 group, how many disks should be used ?
@scottalanmiller said in XenServer 7: best practice: noob question:
Even for software RAID experts, hardware RAID is easier.
Ok, hardware RAID it shall be.
When using SSDs for VM storage, is there a performance difference RAID10 vs 5? (I realize RAID10 will cost you more per TB)
Does it have better performance & is it easier to setup?
@DustinB3403 said in XenServer 7: best practice: noob question:
For XS, if the Linux software RAID is better, why not just always recommend that option & why is this not a supported option?
Because Hardware RAID is more easily protected, with built in batteries.
What makes the Linux software RAID better?
@scottalanmiller said in XenServer 7: best practice: noob question:
They CAN be, but it is FAR less recommended there. Using Storage Spaces is just a fancy MS world marketing term for software RAID. And MS Software RAID is not considered to be enterprise ready. Linux Software RAID is and has been for decades.
So if on XenServer you hear hardware RAID recommended over software RAID, that's a minor recommendation.
For XS, if the Linux software RAID is better, why not just always recommend that option & why is this not a supported option?

- Best practices dictates that you install to USB, and clone USB to "backup USB"
- No never use fake raid
Using this method? http://mangolassi.it/topic/8537/how-to-clone-a-xen-usb-on-windows
I assume there is no way to make the clone without removing the USB stick from the XS box?

I switched to 1Password. They have a utility to import your LastPass info.
One problem: the Mac version gets more love/more updates/looks sleeker/works better vs the Windows versionWhat about the mobile version? I haven't been very impressed with the mobile version of LastPass at all, so wouldn't be hard to make a large improvement.
The iOS version is good. I don't know (nor have I checked) if they have an Android version.

@scottalanmiller said in XenServer 7: best practice: noob question:
HBA is for external drives. XenServer only officially supports hardware RAID controllers but includes enterprise software RAID. Either are fine. But generally you want hardware RAID in the SMB space.
I asked about HBAs because in the MSFT world with Storage Spaces HBAs can be used for internal drives.
@DustinB3403 said in XenServer 7: best practice: noob question:
RAID1 if you were going to do a RAID'd boot partition. (huge waste of resources though) and RAID10 for the VM storage if your drives are "classic Winchester drives. Otherwise if you're using SSD for the VM storage RAID 5.
I thought RAID5 was a no-no. I'm pretty sure I've read that somewhere on these forums.
Any specific recommended brand/model of USB stick?

@DustinB3403 said in XenServer 7: best practice: noob question:
Use a USB flash drive, it's super simple to clone for backup purposes and easily replaced. Using fake RAID is completely worthless.
With XenServer you could do RAID1 SSD, and then RAID10 (winchester) drives using MDADM. Hardware raid is recommended though.
Why waste the money for SSDs for the boot device? USB is so CHEAP, and so simple to backup and clone.
I hear you on the fake RAID.
The RAID 1 or 10 you mentioned, it that for use as boot drive & VM storage?
I know USB is cheap, but I have a few small SSDs laying around.
