Technical Papers: StarWind Virtual SAN®VAAI (vStorage API for Array Integration)
Configuration and Performance Tuning Guide

Published: February 14, 2018

VAAI (vStorage API for Array Integration) is a complex of technologies designed to offload certain VM disk operations to the storage array. With VAAI is enabled during working with the disk subsystem, the ESXi host sends the commands to the array to perform the specific operations. Therefore, there is no need to process all the data. This guide describes how to configure and check VAAI functioning in StarWind Virtual SAN.

Technical Papers: StarWind Deduplication Analyzer

Published: February 8, 2018

StarWind Deduplication Analyzer is a free software product allowing to estimate how data deduplication can optimize your storage capacity. It is released in two versions: for analyzing the shared network and local folders on Windows, and for working with ESX Datastore. This technical paper provides a step-by-step guide for running StarWind Deduplication Analyzer.

Technical Papers: StarWind Virtual SAN Asynchronous replication and Disaster Recovery

Published: January 31, 2018

Disaster recovery site is vital for any business. On-site redundancy does not guarantee the ultimate data protection. To ensure the safe data storing, StarWind provides asynchronous replication. This technical paper discusses setting up asynchronous replication between two nodes and basics of snapshot management in StarWind Virtual SAN environment.

White Papers: Fault Tolerance and High Availability

Published: December 26, 2017

StarWind Virtual SAN eliminates the single point of failure for storage in virtualized infrastructure by using duplication and triplication of data, caches and I/O controllers, basically “mirroring” them all between independent physically different hosts. This way, the virtual shared storage becomes faulttolerant and provides high availability to higher performance and low-cost.

Technical Papers: Creating Highly Available device using Node Majority Failover Strategy

Published: December 19, 2017

The simultaneous connection loss between nodes may cause “split brain” scenario, the state when nodes proceed read and write requests independently from each other. This incoordination causes data corruption after connection resumption. Setting up the failover strategy helps avoid the issue. This technical paper describes setting up an HA device using the Node Majority Failover Strategy with Witness Node on StarWind Virtual SAN as a storage provider.

Technical Papers: How to enable iSER in StarWind Virtual SAN

Published: December 7, 2017

This document describes how to enable iSER, a topnotch data transfer iSCSI extension for RDMA, in StarWind Virtual SAN environment. Enabling iSER allows increasing the speed of VM migration and data replication. Additionally, iSER provides all the advantages of the iSCSI protocol, including security and simplicity.
