More R functions for interacting with the EDI Repository API

The EDI Repository Data Package Manager and Audit Manager Application Programming Interfaces (APIs) facilitate automated data publication and science workflows. Thirty-six new R functions, supporting 60% of the available API calls, have been added to the EDIutils R library. The remainder will be added soon! Learn more about the functions and associated use cases at the EDIutils website.

we’d like to get contributions from the wider environmental information
management community. The Spring 2019 issue is in preparation and we’d
love your input! Articles should be submitted to jporter@virginia.edu
by the Ides of March (15 March 2019). We would welcome contributions in all areas of environmental information management including feature articles, Tech Tips, reviews of books or articles and commentaries. Databits is a newsletter, so articles don’t need to be long and complicated. Just interesting and informative!

EDI behind the curtains

EDI technical staff recently upgraded our virtualization infrastructure to the latest version of VMware’s ESXi software (from version 5 to 6.5). All of EDI’s servers, including those that run the PASTA+ data repository software, operate as virtual clients across six ESXi host systems. These virtual hosts are configured to operate between 6 and 12 clients at one time, with some room left over to shuffle systems  and for testing. The ESXi host systems are located on the campus of the University of New Mexico and connect directly to a dedicated 10Gb/s connection using UNM’s Science DMZ research network. Wide-area Internet connectivity to UNM includes 100Gb/s connections to the DOE Energy Sciences Network (ESNet) and the Western Regional Network, both through the Albuquerque Gigapop. EDI’s data storage capacity is currently at 30TB, with an equivalent 30TB mirror storage device for near-time backups and smaller SSD disks that are used for off-site backup purposes. EDI also uses the AWS Glacier storage as a long-term “cold data” archive.
