NEWS! Changes to migration timeline and further testing. Announcement of ECPDS migration. |
Transition plan
As part of our Data Centre move we have started the installation of ECPDS, the ECMWF Production Data Store, in Bologna
, Italy. ECPDS, which is described in a Newsletter article, takes care of both the dissemination and acquisition of data. For the migration of the
operational ECPDSdissemination we are currently considering two options:
- Incremental move of individual data streams
- Switch-over of all data streams together with the switch-over of the operational forecast
We will confirm at a later date which option will be used.
As a first step to prepare for an operational ECPDS in Bologna we are asking recipients of operational data to make changes to their network setup. We will also offer transfer tests to ensure that external hosts will be ready for the switch-over of the operational forecast production from Reading to Bologna, expected for
AprilJune 2022. Please note that until then the operational forecast will continue to originate from our Reading Data Centre. A separate page regarding the release candidate test phase of the forecast production will be published soon.
Indicative timeline
The operational switch-over is currently expected for June, date TBC.

Action required by dissemination users/sites
Note | ||
---|---|---|
| ||
We are progressing with the testing of dissemination from our Bologna Data Centre and completed our first round of tests with users on 12th January. Please refer to our updates below. |
Dissemination via the Internet or RMDCN
If you received test files on 12th January: No immediate further action is required. We will contact users closer to the migration date to repeat the test and inform you of the migration process.
If you did not receive these files:Shortly we will announce another test date. Please 'watch' this page to be notified of this announcement and refer to the Connectivity Tests Announcement: 29th October 2021 below with full details of the action required in readiness for these tests. To support further testing you may need to create a test directory which allows us to push the test files to.
Dissemination via ecaccess or LAN
Our installations are not yet complete in Bologna. We will update this page shortly to inform users when these services are available for testing. Please 'watch' this page to be notified of updates.
Dissemination via ftp pull
Please try connecting to the host diss.ecmwf.int with the same username and password credentials that you use to access ECPDS in Reading. If you have any issues connecting, please raise a ticket via our Support Portal.

Please update your firewall rules at your earliest convenience, at the latest by 30 Nov 2021, to accept connections from our new IP addresses used in Bologna: Internet:
RMDCN:
Please note that for ftp we support the following ports: For sftp we support: Please ensure to keep the current firewall rules in place to allow connections from our Reading Data Centre subnets until its decommissioning in the second quarter of 2022. We are planning to test the connection on the 11th and 12th of January. Therefore, please make sure your system is set up to receive these file name patterns. The test will involve the transfer of files named "ecmwf-tst.bol" and "ecmwf-tst.md5". Please check if you have received these files and test the .md5 file using this command: md5sum -c ecmwf-tst.md5 and confirm that it is OK. Once you are happy, please delete the file so that we can test again if required. |
