### Parallels Business Automation - Standard Hardware Requirements

Recommended hardware configuration is two or more computers for Hardware Nodes.

Note: Parallels Business Automation - Standard can work well with just one Hardware Node, but existence of two nodes increases availability of the hosting service. With two or more nodes one of them may be taken off-line for maintenance, replacement or upgrade with minimal disruption for the hosting service.

If you use Parallels Virtuozzo Containers, we recommend installing the Management Node software in a special service Container hosted on one of your Hardware Nodes. In this case that single computer shall meet both Hardware Node and Management Node requirements and you then need at least one workstation for system administrator to manage it.

However, you can have your Management Node as a separate computer.

Management Node requirements (if the Management Node is a separate computer)

- IBM PC-compatible computer with 2 GHz (or higher) Intel Celeron, Pentium, or AMD Athlon CPU;
- At least 1 GB of RAM;
- At least 40 GB of total disk space;
- Network card;

Virtuozzo Hardware Node Requirements

- IBM PC-compatible computer;
- Intel Celeron, Pentium II, Pentium III, Pentium 4, or AMD Athlon CPU;
- At least 128 MB of RAM;
- Hard drive(s) with at least 4 GB of free disk space;
- Network card (either Intel EtherExpress100 (i82557-, i82558- or i82559-based) or 3Com (3c905 or 3c905B or 3c595) are recommended).
- SCSI controllers:
  - Adaptec7xxx SCSI controller (including AHA 2940/3940/3944/29160);
  - RAID controller based on the AMI MegaRAID chips (including DELL PowerRAID PERC2/PERC3).

Caution: For Athlon-based systems: It is not recommended to use computers with VIA chipsets.

Plesk Hardware Node Requirements:

The minimal hardware requirements for the Plesk installation are the same as those of the operating system intended to be used with Plesk.

Number of domains | Amount of RAM | Processor
100 | 256 MB | Pentium II
500 | 512 MB | Pentium III
1500 | 2000 MB | dual Pentium III
2000 | 4000 MB | dual Pentium IV
