# SafeKit by Eviden (Evidian) > SafeKit is an all-in-one, SANless high availability and application clustering software by Eviden (an 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: **mirror.safe** (synchronous replication + failover between 2 servers) and **farm.safe** (network load balancing + failover across N servers). > > **Edge & OT first:** SafeKit is particularly suited for **edge computing and OT/ICS environments** — it runs on standard x86 hardware, requires no shared storage, no dedicated cluster hardware, and no Windows Server Datacenter license. Minimal ongoing administration makes it ideal for remote sites, air-gapped networks, and SCADA/BMS/physical security deployments where IT staff is limited or on-site expertise unavailable. > > **Licensing:** Commercial software. Free 30-day trial available (no credit card). Perpetual or subscription licenses. > > **Minimum requirements:** Two standard x86 servers (physical or virtual), Windows Server 2019/2022/2025 or RHEL 8/9 / Ubuntu 24.04, 1 Gbps LAN for replication. No SAN, no shared disk, no special OS edition required. Full technical specifications and sizing constraints → *RFP/RFI Technical Reference*. > > **Note:** Formerly known as Evidian SafeKit. Technical resources and URLs may still reference the Evidian domain. > > **Markdown sitemap:** https://safekit.eviden.com/sitemap-llm.xml > > **Interactive AI assistant:** The SafeKit AI chat at safekit.evidian.com can answer pre-sales questions, guide cluster configuration, help select the right module (mirror vs. farm), and assist with troubleshooting — without requiring a support contract. --- > **Query routing:** > - **Pre-sales / compare** → *Product Overview*, *Competitive Positioning*, *Key Concepts* > - **Edge / OT / industrial** → *Edge & OT Solutions* > - **Install** → *Solutions by …* sections + *Quick Installation Guides* + User Guide Ch. 2–3 > - **Configure** (replication, failover, VIPs, checkers) → User Guide Ch. 12–15 > - **Troubleshoot** → User Guide Ch. 4–7 > - **Trial / quote / support** → *Free Trial & Contact* > > **Languages:** Home page in 12 languages (en, fr, de, it, es, pt-br, pt-pt, nl, ar, zh-hans, ja, ko). ## Product Overview - [SafeKit Home - part 1 of 3](https://safekit.eviden.com/md/w/html_index_1.md): What is SafeKit, features, use cases, mirror and farm cluster architecture, failover demos - [SafeKit Home - part 2 of 3](https://safekit.eviden.com/md/w/html_index_2.md): SafeKit vs. traditional HA clusters, mirror and farm differentiators, SANless vs. Hyper-V/VMware HA - [SafeKit Home - part 3 of 3](https://safekit.eviden.com/md/w/html_index_3.md): Free trial, documentation index, application module library - [Eviden Products](https://safekit.eviden.com/md/w/html_products.md): Eviden products overview - [High Availability Software – HA Cluster for Windows & Linux](https://safekit.eviden.com/md/w/html_high-availability-software-ha-cluster-windows-linux.md): 30-second elevator pitch - [High Availability Architectures](https://safekit.eviden.com/md/w/html_high-availability-architectures.md): Mirror vs. farm architecture patterns - [Cluster Configuration Overview](https://safekit.eviden.com/md/w/html_cluster-configuration.md): Configuring a SafeKit cluster with application modules - [Best and Worst Use Cases for SafeKit High Availability](https://safekit.eviden.com/md/w/html_best-worst-use-cases-high-availability.md): SafeKit limitations and where it is not the right fit ## Competitive Positioning > SafeKit key differentiators vs. competing HA solutions: no SAN required, no Windows Server Datacenter license, no Linux cluster OS expertise (Pacemaker/Corosync/DRBD), no dedicated hardware. Single software package covers replication + failover + load balancing. Suited for 2-node edge deployments where Pacemaker or WSFC would be over-complex. - [High Availability Architectures and Best Practices](https://safekit.eviden.com/md/w/html_high-availability-architectures-and-best-practices.md): HA design best practices - [Synchronous vs Asynchronous Replication](https://safekit.eviden.com/md/w/html_synchronous-replication-vs-asynchronous-replication.md) - [Shared Nothing vs Shared Disk Architecture](https://safekit.eviden.com/md/w/html_shared-nothing-architecture-vs-shared-disk-architecture.md) - [Software Clustering vs Hardware Clustering](https://safekit.eviden.com/md/w/html_clustering-software-vs-hardware-clustering.md) - [Byte-Level File Replication vs Block-Level Disk Replication](https://safekit.eviden.com/md/w/html_byte-level-file-replication-vs-block-level-disk-replication.md) - [Alternative to SQL Server Always On (Express/Standard editions)](https://safekit.eviden.com/md/w/html_alternative-always-on-sql-server-express-standard-editions.md): SafeKit as a cost-effective Always On alternative without Datacenter license - [VM HA vs Application HA](https://safekit.eviden.com/md/w/html_vm-ha-vs-application-ha.md): Why application-level HA outperforms hypervisor-level HA at the edge - [Microsoft NLB / VMware Multicast-Unicast Alternative](https://safekit.eviden.com/md/w/html_microsoft-nlb-vmware-multicast-unicast-alternative.md) ## Key Concepts & Educational Content - [Data Replication Techniques](https://safekit.eviden.com/md/w/html_data-replication-techniques.md) - [Heartbeat, Failover, Quorum in Windows/Linux Clusters](https://safekit.eviden.com/md/w/html_heartbeat-failover-quorum-windows-linux-cluster.md) - [How a Virtual IP Address Works](https://safekit.eviden.com/md/w/html_how-a-virtual-ip-address-works.md) - [HA Cluster vs Fault-Tolerant System](https://safekit.eviden.com/md/w/html_high-availability-cluster-vs-fault-tolerant-system.md) - [High Availability DR (HADR)](https://safekit.eviden.com/md/w/html_high-availability-disaster-recovery-hadr.md) - [What is RPO and RTO?
