Hardware for TeskaLabs LogMan.io

This hardware specification is designed for vertical scalability. It is optimised to build a TeskaLabs LogMan.io cluster with the lowest possible cost yet with the possibility to add more hardware gradually as the cluster grows. This specification is also fully compatible with the horizontal scalability strategy, which means adding one or more new server node to the cluster.

Vertical scalability

  • Rear HDD trays: 2 drive bays, 2.5", SATA, for OS HDDs, hot-swap; to offload space in the 3.5" front trays
  • Network card: 10Gbps Ethernet NIC SFP+, single or dual; other NIC are available on request
  • Add one more CPU (2 CPUs in total), a motherboard with 2 CPU slots is required for this option
  • Add RAM up to 512GB
  • Add up to 9 additional Data HDDs, maximum 220 TB space using 12x 20 TB HDDs in software RAID5

Note

1U, 3U (16 drive bays) and 4U (24 drive bays) variants are also available.
