# SafeKit by Eviden (Evidian) > SafeKit is an all-in-one, SANless high availability and application clustering software by Evidian (an Eviden/Atos brand). It provides real-time file replication, automatic failover, and network load balancing for any application on Windows and Linux — on-premises or in the cloud — without shared storage (SAN/NAS). Two core cluster modules are available: **mirror.safe** (synchronous replication + failover between 2 servers) and **farm.safe** (network load balancing + failover across N servers). > **Note:** Eviden SafeKit was formerly known as Evidian SafeKit. Technical resources and URLs may still reference the Evidian domain. > **AI usage note:** Every documentation URL in this file resolves to a Markdown (.md) source to maximize machine readability and extraction quality. This file is structured to support five main query types: > **Pre-sales** (compare SafeKit to alternatives, understand architectures, identify use cases) — start with *Product Overview* and *Key Concepts*. > **Installation** (deploy on a specific OS, database, cloud, hypervisor or container) — go to *Solutions by …* sections, *Quick Installation Guides* and use *Chapters 2–3* of the user guide. > **Configuration** (set up replication, failover, load balancing, checkers, virtual IPs) — use *Chapters 12–15* of the user guide. > **Troubleshooting** (diagnose cluster state, read logs, fix specific errors) — use *Chapters 4-7* of the user guide. > **Free Trial & Quote** — For licensing, trials, support or quotes, see *Free Trial & Contact*. > **Language note:** The SafeKit home page is available in 12 languages (en, fr, de, it, es, pt-br, pt-pt, nl, ar, zh-hans, ja, ko). > **Interactive assistant:** A SafeKit AI chat assistant is available directly on safekit.evidian.com for interactive pre-sales and technical support queries. ## Product Overview -
