dCache: – Added: 2 servers ( Qtech QSRV-462402_3) = ~0.68 PB

EOS: – Added: 20 servers (Qtech QSRV-462402_4) . Sum(capacity): 22.353 PB

2023:

8 old disk servers were removed, 4 new DELL R740 of 300 TB each were added. SE disk has 4 servers; in EOS – 28. Added: 2 servers (Qtech QSRV-462402_3) = 681.1 TB.  EOS Added: 20 servers (Qtech QSRV-462402_4)

As a result, we currently have:

2018 CICC architecture and facilities

 

In 2020, the following works were performed to change the configuration of Tir2 (JINR-LCG2):

1) Changed batch server to Slurm type. Works and is used by CE.

2) Changed Computing Element (CE) for WLCG type – ARC6 (internal slurm queue). (CREAM-CE is no longer supported by the central task launcher).

3) the farm is transferred to Scientific Linux release 7 system.

4) Added new tape robot (TS4500).

5) PhEDEx is replaced by RUCIO.

6) New servers are connected in EOS.

7) User interface lxui [01-04] .jinr.ru as a gateway for external connections

8) Increased disk space of the interactive cluster /scrc (2.2TB)
