Nice changes at Prometeus
Dear Lee,
we're excited to share with you some upgrade of our main point of presence in Milano.
- New datacenter facility.
In the next 2-4 weeks we will move all of our equipments to a new Tier 4 facility located inside the same campus we are colocated right now. The new datacenter will offer us the opportunity to grow and more resilience for our services.
More information about the new datacenter here: http://www.caldera21.com/en/
We will move our equipments in small batches, to keep the downtime to a minimum (most servers will experience no more than 1-2 hours of downtime). You will receive a notice of the exact schedules a couple of days before every move.
iwStack servers (both Milano DC1 and DC2) will be moved along the Storage Area Networks, so we will power down the servers then the SANs, move to the new rackes and power on everything up. We estimate 4 hours of downtime.
- New network backbone.
Our current network backbone is based on dual 10Gb paths between core switches. We have just installed at the new location new switches with dual 40Gb paths and high density 10G ports for the distribution.
Some existing servers will be upgraded to 10G after the migration and new servers will use 10G nics by default in future.
- BIZ Xen storage upgrade
All servers will be upgraded with SSD disks. As part of this process we will need to migrate the VPS to already SSD powered servers.
- KVM5 / KVM7 / KVM9 storage upgrade
All servers running on SAS disks will be upgraded with SSD disks. As part of this process we will need to migrate the VPS to already SSD powered servers.
- OpenVZ storage upgrade
we had already moved 80% of our openvz vps to SSD storage in the last two years. Remaining VPS on sas disks will be moved to SSD powered nodes as part of the datacenter migration.
As you can understand some of the planned upgrade will require some downtime, so we will apologize in advance for any inconvenience. Thanks in advance for your patience.
Best regards
Prometeus Team

That's how you treat customer like a boss.
What will happen to existing XenPower VPSs?
Due to instability with the 4.x and onwards, we cannot upgrade it yet, and this means serious issues with newer kernels, such as jessie and unbootable VMs after upgrade, this is probably just the beginning, the problems will grow and multiply.
Until there is a stable release, we must stay on the fence, even consider winding it down. We have a plan B involving KVM replacement.
Existing VMs will not be terminated, of course, we will move them like all the others.
These changes are due to capacity issues, for a long time we had to refrain from extending in Milano, and had to go elsewhere.
Now this is solved as the new DC is very large. Since we had to build another, at least it is state of the art.
Will there be new KVM ssd line
priced similar to Xenpower ssd? (just saw the latest kvm ssd prices; Just a stock issue now. )of course, iwstack ssd is the way to go for 'servers as cattle' philosophy of capacity planning. #iStillLikePets
I am sorry but I do not understand. The current KVM (ssd or not) line is not intended to replace Xen, we will do that if and when we have no choice but to abandon it. Will still live on in the form of XenServer with IWStack, but even that is not a given if it behaves anything less than stellar through the upgrades.
Just a question: In Romania it seems like you throttle the iwstack E3 cores. In Netherlands you don't. Does that mean that throttling could come at any time in NL aswell?
KvmPower please.
No. Romania has different hardware, not E3s, but E5s.
Then the description in /proc/cpuinfo is wrong.
Can we safely upgrade from Ubuntu 12.04 to Ubuntu 14.04 on XenPower VPS?
