System requirements

This document lists system requirements for management servers, aggregators, bonders, and private WAN routers.

Management server

• Environment: bare metal (recommended for performance), ESX, Xen (PV-GRUB or HVM), KVM, etc.
• CPU: minimum 4 cores, Xeon CPU Ivy Bridge (2013)
• RAM: minimum 8 GB
• Disk:
  • minimum 100 GB, SSD, 1000 IOPS
  • 100 GB supports metric collection for 30 bonds at default resolutions
• Network:
  • Ethernet: One 100 Mbps or 1 Gbps interface
  • IP address: One static public IP
• Recommended - remote KVM ability such as IPMI or ILO

Time series database server (recommended > 250 nodes)

Disk IO is a priority. Disks should be directly attached have good performance. You can see massive performance penalties when the disk writes cannot keep up.

From https://docs.influxdata.com/influxdb/v1.2/guides/hardware_sizing/#general-hardware-guidelines-for-a-single-node

• Environment: bare metal (recommended for performance), ESX, Xen (PV-GRUB or HVM), KVM, etc.
• CPU: 8 or more core Xeon CPU Ivy Bridge (2013) or newer
• RAM: minimum 16 GB
• Disks:
  • 1000 IOPS minimum for influx disks; the wal disk is more important for IOPS
  • 250 GB SSD mounted at /var/lib/influxdb/wal
  • 250 GB SSD mounted at /var/lib/influxdb/data
  • separate mechanical disk or SSD for Debian OS
• Network:
  • Ethernet: 1 Gbps interface on same LAN as management application server
  • IP address: One static IP reachable from the management application server
• Recommended - remote KVM ability such as IPMI or ILO

For >1000 nodes, system requirements need to be increased further:

• Environment: bare metal (recommended for performance), ESX, Xen (PV-GRUB or HVM), KVM, etc.
• CPU: 16 or more core Xeon CPU Ivy Bridge (2013) or newer
• RAM: minimum 32 GB
• Disks:
  • 1000 IOPS minimum for influx disks; the wal disk is more important for IOPS
  • 500 GB SSD mounted at /var/lib/influxdb/wal
  • 500 GB SSD mounted at /var/lib/influxdb/data
  • separate mechanical disk for Debian OS
• Network:
  • Ethernet: 1 Gbps interface on same LAN as management application server
  • IP address: One static IP reachable from the management application server
• Recommended - remote KVM ability such as IPMI or ILO

Aggregators

• Environment:
  • bare metal (strongly recommended for performance), ESX, Xen (PV-GRUB or HVM), or KVM
  • see virtualization considerations on provisioning aggregators.
• CPU:
  • Intel Xeon CPU Ivy Bridge (2013) or newer with at least 4 cores
  • if encryption is enabled for the tunnel or private WAN, AES acceleration instruction set is recommended for faster speeds
• RAM:
  • minimum 2 GB (supports 50 bonds/1 GB memory)
  • add 50 MB for every bond running TCP proxy (when TCP proxy is enabled on at least 1 bond, aggregator needs more memory and this can vary depending on the speeds set on the bond)
• Disk: minimum 16 GB
• Network:
  • Ethernet: One gigabit interface
  • IP address: One static public IP
  • Internet uplink: Sufficient bandwidth for all bonds assigned to the aggregator, considering oversubscription ratio if applicable. For example with two bonds, each with two 10/10 Mbps legs, the aggregator would need 40/40 Mbps bandwidth to Internet, assuming no oversubscription. Using an oversubscription ratio of 4:1, the aggregator could be given 10/10 Mbps bandwidth.
• Recommended - remote KVM ability such as IPMI or ILO

Bonders

• Environment: bare metal, ESX, Xen
• Throughput and required CPU is listed in the performance ratings document:
  • If tunnel encryption is enabled, AES acceleration instruction set is recommended for faster speeds
• RAM: 256 MB minimum, 1 GB recommended
• Disk: minimum 4 GB. For highest reliability, use hard disks, solid state disks, or flash storage with good wear-leveling algorithms. Flash storage without good wear-leveling algorithms tend to fail sooner than other types of storage.

Private WAN routers

• Environment:
  • bare metal, ESX, Xen, or KVM
  • see virtualization considerations on provisioning private WAN routers.
• CPU:
  • Intel Xeon CPU Ivy Bridge (2013) or newer with at least 4 cores
  • if private WAN encryption is enabled, then AES acceleration instruction set is recommended for faster speeds
• RAM: minimum 4 GB, add 50 MB/private WAN space and can use more depending on the number of routes the space has.
• Disk: minimum 4 GB. For highest reliability, use hard disks, solid state disks, or flash storage with good wear-leveling algorithms. Flash storage without good wear-leveling algorithms tend to fail sooner than other types of storage.
• Network:
  • Ethernet: One gigabit interface
  • IP address: One static public IP
  • Bandwidth: Sufficient bandwidth for all bonds assigned to private WAN in this routing group, considering your oversubscription ratio if applicable.
