Requirements

Linux Distributions

  • Ubuntu 16.04, 18.04
  • RedHat Enterprise Linux 7.x
  • CentOS 7.x
  • Debian 8.x, 9.x

Processor Architecture

  • x86_64 / 64-bit

CPU and Memory

  • RAM: 16 GB
  • CPU: 10 GHz

To calculate the available CPU capacity, multiply the number of cores by CPU clock speed, for example 4 x 2.5 GHz = 10 GHz.

Disks

  • Disk Type: SSD
  • Application files: 2 GB.
  • Daily log files: 20 GB.
  • Market data: 200 GB.

File System

The standalone version is supported on local ext4 file system.

Scale-out deployment is supported on Apache HBase on file systems such as Hadoop (HDFS), Amazon EMRFS, and Azure Storage.

OS Settings

  • Increase ulimit nofile parameter to at least 32768.
  • Enable NTP. If co-located at the trading venue, synchronize with NTP servers operated by the exchange.

Network Settings

Increase network buffers and disable Reverse Path Filtering.
