Tesco and XCP-ng
-
Why, any hint in there that would be XCP-ng?
-
@olivierlambert "Tesco's systems administrators have selected for the job, though the Ars Technica report says that the choice appears to be incompatible with both Veeam and Zerto, suggesting it's a lesser-known offering."

There are many alternative solutions, not just us
-
@olivierlambert but we want it to be XCP on Vates stack !
-
I won't be against it obviously. But I'm not the one making the choice
-
@olivierlambert just for fun of thought.
How could Vates stack handle 40K servers farm ?I suppose TESCO have multiple in house datacenters, and not 40K servers in one place but anyway...
Can this tech handle 40K servers in one XOA with attached sites by XO Proxies ?way above recommend limits isnt it ?
don't remember the max number of servers per pool -

don't remember the max number of servers per poolIf it’s the same as the Xen Server limit, then hosts 64 per pool.
So would need to split the 40K servers over multiple pools, if all identical each with 64 hosts until reach that number. The number of pools would still be very high, at least until the per pool limit can be raised to 1,000 to 2,000 per pool, or around that amount!
-
@john.c yeah i'm assuming the 40K is probably VMs, so better density of physical servers
anyway, big players... -
Even with existing customer with that many VMs or host, absolutely nobody will do a giant pool. And in the ROBO/edge world, it's mostly 2 or 3 machines per shop.
Even large DC deployments tend to use around 10 hosts per pool (a good sweetspot between convenience and fallout protection in case you have a problem on a pool).
