Present: Marcos, Jonas, Florido, Caterina, Oxana

* MoU: the text is almost ready [1]; LUNARC has also prepared an SLA with MAX-IV, which is shorter, so our MoU can be still shortened. Florido would need ~1 week to finalize it.

* Software: Florido tested the test scripts, and they mostly work on CentOS7 out of the box. The bits that did not, work in Singularity. Compilation takes ~5min, after which a working execution environment is ready; this can be deployed as a separate pre-emptive job, saving time for other jobs.

* Storage: Florido prepared a design sketch [2]. Jonas already contacted Swestore and they started making the necessary arrangements for new Grid pools. The proposed deal is to have 80 TB of storage with 5 years support at 51 KSEK. Discussion ensues on whether faster disks/better performance is needed - if so, a new quote will be required, and will be several times more expensive. A mixture of different technologies/file systems is also a possibility. Another option is to buy the existing offer and add SSDs/faster disks if and when better performance will be needed. For faster disks, specs needs to be cross-checked and a new quote requested, eventually. The final decision is to place an order for the existing offer. Delivery time is 2-3 weeks, followed by 2 weeks for installation and connection to dCache, followed by commissioning. Early December is a viable date for full readiness.

* CentOS7: Singularity is ready to be used, the missing bits are user instructions and upgrade procedures. If in-place upgrade via yum is not possible, images will be upgraded periodically using a CentOS6 machine.



* Actions:
- Florido finalizes the MoU
- Florido asks Anders to place the order with ATEA for the 80TB option
- Marcos contacts Singularity developers regarding the in-place image upgrade via yum
