Note Note: August 14, 2018

Incomplete Partially done The ATS testing and creation of packages is going well and some is already in production. This is doing the basic needs so far but nearly done.
In progress In progress ACME service is also on track
In progress In progress Increasing network capacity goal is moving much slower than expected, due to hardware installation (network switches) on the switch stacks issues with the vendor. This goal is at risk for this quarter due to these hardware and testing issues with the new/old switches. The replacement routers will also be at risk for this quarter.

Incomplete Partially done September 2018

  • Yes Done This goal is fully complete; an ATS test cluster has been setup in both core DCs.
  • In progress In progressACME software has been written, deployment and use is expected by end of the quarter.
  • In progress In progressIncreasing network capacity goal has hit a roadblock, due to network switch stack topology incompatibility issues with the vendor, causing network instability in production. This goal is at risk for this quarter, as we can neither take any risks nor move swifty on this very essential and critical infrastructure. The replacement of the routers is expected to complete before EOQ.

Status[edit source]

Note Note: July 2018

In progress In progress

Note Note: August 10, 2018

In progress In progress discussed working on getting eqiad to play well with MAIN (shared services)

Note Note: September 12, 2018

In progress In progress * Arturo found a way to transparently route traffic between the legacy Nova Network deployment and the new Neutron deployment. This should make migrating projects to the new deployment significantly easier and more transparent for our end users.
In progress In progress * Also, Progress is currently stalled due to unexpected hardware compatibility issues with Debian Jessie on new cloudvirt servers. We are getting a lot of help from the DC Ops team and Moritz to find solutions for these issues, but until we have a working combination of hardware & software we are holding off on procuring new servers. This in turn will slow the rate at which we can move projects to the new deployment. This is of larger impact for our Q2 continuation of this program than it is to meeting the current Q1 goal of moving at least one project.
