Maintenance Notification:
On next Monday August 5th 2019 starting at 7am CEST we will conduct some maintenance. You might encounter some issues using the Exasol User Portal and Issue Tracker! We will restore the Exasol User Portal and Issue Tracker before 9am CEST on Monday August 5th 2019.

General Requirements

  • CPU
    • EXASuite only runs on 64-bit Intel platforms with SSSE3 featured CPUs (Xeon Woodcrest upwards).
  • Firmware Interface
    • EXASuite currently only supports the classic Basic Input/Output System (BIOS) firmware interface. Deactivate the Unified Extensible Firmware Interface (UEFI) if applicable.
  • Network
    • Depending on the network topology (see Network Planning), the servers need to be equipped with two or more dedicated 1- or 10-Gbit Ethernet network interface cards.
    • Intel network chipsets are known to work best although chipsets from other manufacturers may work as well.
  • Storage Subsystem
    • SAS (Serial Attached SCSI) is the preferred bus technology and hard drive interface
    • SSDs (Solid-State Drives) are supported but not certified.
    • Use of hardware RAID controllers with RAID-1 pairs (mirroring) is recommended for added hardware reliability in the case of a failure
    • The more spindles EXAStorage has, the more parallelism there will be on read write operations
  • Out-of-band Management
    • The preferred protocol to connect to Lights-out-Management interfaces is IPMI (Intelligent Platform Management Interface, version 2.0).
    • Enterprise license recommended

Cluster Node Requirements

EXASolution clusters are composed of one or more database nodes and at least one management node (called "license server"). Database nodes are the powerhouse of a cluster and operate both the EXASolution instances as well as the EXAStorage volumes.

Database nodes are expected to be equipped with homogeneous hardware. EXASolution and EXAStorage are designed and optimized to distribute processing load and database payload equally across the cluster. Inconsistent hardware (especially differences in RAM and disk sizes) may cause undesired effects, ranging from poor performance to service disruptions.

License servers are the only nodes of a cluster that boot from local disk. They are installed from an EXASuite installation ISO image.

Database servers are installed and booted from the license server over the network via PXE (DHCP + TFTP).

Management Node

Minimum hardware requirements:

  • Single socket quad core Intel CPU
  • 8 GB RAM
    • 2x 300 GB hard disks
    • 2x network adapters with at least 1 GB/s
  • DVD drive for installation (alternatively: virtual media on lights-out-management)
  • Recommended:
    • Hardware RAID controller
    • Lights-out-management interface

BIOS settings:

  • Boot order: DVD, hard disk drive
  • Power management: maximum performance (static)
  • Processor options: hyper-threading enabled
  • Disable UEFI
Database Node

Minimum hardware requirements:

  • 2x Quad core Intel CPU (XEON)
  • 16 GB RAM (32 GB RAM recommended)
  • Hardware RAID controller
    • 2x 128 GB SAS hard disks in RAID-1 (Operating system)
    • 4x 300 GB SAS hard disks in RAID-1 (Database payload)
  • 2x network adapters with at least 1 GB/s (PXE enabled on NET-0)
  • Recommended: lights-out-management interface

BIOS settings:

  • Boot order: PXE (network boot) from NET-0
  • Power management: maximum performance (static)
  • Processor options: hyper-threading enabled, virtualisation enabled
  • Disable UEFI

Information

Note on CPU: The clock speed and number of cores you need for your system depend heavily on the planned workload. An analytic batch system benefits faster CPUs while a higher number of cores is recommended for systems with many parallel processes (concurrent connections).
