The EOS storage system has been steadily deployed on the Grid SE for ALICE over the past years. Presently, more than 1/2 of the ALICE total disk storage capacity is managed by EOS, with this fraction increasing every day. For the ALICE upgrade, EOS will also be installed on the large (60PB) disk buffer, which will hold the RAW data collected through the data taking year.

A 2020 update of our current experiences and challenges with running an EOS instance for use by the Fermilab LHC Physics Center (LPC) computing cluster. The LPC cluster is a 4500-core user analysis cluster with 7 PB of EOS storage which is an increase of about 40% over 2018. The LPC cluster supports several hundred active CMS users at any given time. We will also discuss our recent upgrades...

The Institute of High Energy Physics undertakes many large scientific engineering projects in China. These large scientific projects generate a large amount of data every year and require a computing platform for analysis and processing. Among them, the LHAASO experiment to be constructed in 2021 will generate about 6PB of data each year. EOS, as the main data storage system of the LHAASO data...

Root protocol is a standard way to access data from EOS in a grid environment. The performance of storage is crucial for the effective use of computing resources. One of the questions that could be asked by a person who sends jobs to the grid is the following: how many jobs may simultaneously download data from storage and still be effective? In order to answer this question, a simple test was...

we are in the process of procuring new storage for our Tier2 facility.
3 PB usable total, 1.5PB for each of ALICE and ATLAS.
We will present what we intend to purchase and what motivated those decisions. -
