System Requirements

CPU
Minimum one physical 1.7 GHz processor
RAM
4GB
If using cache or Asynchronous Replication, an appropriate amount of RAM should be added
Network
2 NIC interfaces (StarWind Synchronization and Heartbeat/iSCSI traffic) + 1 NIC (Management)
It is recommended to set jumbo frames (MTU) to 9000 for iSCSI and Synchronization traffic
Network Bandwidth
Synchronous Replication: Minimum 1 GbE or higher
Latency requirements: <5 ms
Asynchronous Replication: Minimum 100 MbE or higher. The data link must be capable to transmit the replicated amount of data within the desired backup window
Hypervisor
Supported Windows Server version: 2012 or later
Storage
3 GB disk space reserved for installation and logging
The StarWind virtual disks must reside on the separate partition from the StarWind installation disk
Hardware RAID controller is highly recommended
Microsoft Storage Spaces is supported
Asynchronous Replication: The storage with replication journals on the primary server should have higher or equal write performance in comparison with the production storage array (on 100% sequential write with 8MB block size). The space reserved for the journal disk must exceed the amount of data written to the production storage array within the time frame between snapshots plus extra 25%
• Software RAID implementations are NOT supported. For recommended RAID settings, please, read the KB article.
IMPORTANT NOTE: Server with LSFS devices and Data Recovery (DR) server (in case of Asynchronous Replication) should fit the LSFS device requirements.
