The facilities at Kryoneri Observatory include the dome building, which hosts the telescope, the telescope control and the guest rooms, the role-off building housing a small telescope, as well as the building that hosts the supporting power generators.
IT infrastructure includes a dedicated (microwave) link of 20 Mbps throughput to the NOA Headquarters in Penteli. The connection is highly secured and reliable and is used for live data transfer of all astronomical, meteorological, and seismological data produced from the installed scientific instruments. Furthermore, a small LAN (at 100Mbps) has been installed in order to support all the scientific activities and personnel requirements.
In 2016, a new LAN of 1Gbps was installed to support the research activities of the upgraded telescope. In addition, a new UPS system and new lightning and earthing systems were installed to provide advanced robustness and reliability in the whole operation of the Observatory. The main Cluster System consists of two (2) nodes HP DL380 Gen9 Servers. Each Server features the following Specifications: (1)1 x Intel Xeon E5-2660v3 processor, (2)64GB Memory (8x8GB 1Rx4 PC4-2133P-R Kits), (3) 2xInternal Storage HP 300GB 12G SAS 10K 2.5in and (4) Smart Array P440ar/2G FIO RAID Controller HP Ethernet 10Gb 2Port 530SFP+ Adaptor.
Each Server interconnects to an HP 2920-24G Switch through dual 10GbE Fiber Connections. For this reason the Switch features 2xHP 2920 2-port 10GbE SFP+ Modules. The Storage Subsystem consists of an HP MSA 2040 SAN DC SFF Storage which includes an additional HP D2700 Disk Enclosure. The Storage Subsystem is populated with 32xHP 1.2TB 6GB SAS 10K SFF DP ENT HDDs, providing a total RAW capacity of 38.4TB. The SAN Subsystem interconnects to the HP 2920-24G switch through eight Gigabit Ethernet Copper Connections over iSCSI.
