VM HA is a generic solution ideal for environments standardized on Hyper-V or KVM, offering redundancy for the entire operating system stack, though with a potentially longer Recovery Time Objective (RTO) due to the VM reboot. Conversely, Application HA provides superior agility and platform agnosticism, including support for VMware, resulting in a much lower RTO by focusing solely on critical application data replication and restart. For the lowest RTO and maximum deployment flexibility, Application HA is the optimal SafeKit choice.\n\n<\/article>\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t<div class=\"sow-accordion-panel\n\t\t\t\t\t\"\n\t\t\t\tdata-anchor-id=\"vm-high-availability-safekits-san-less-vs-hyper-v-vmware-ha\">\n\t\t\t\t\t<div class=\"sow-accordion-panel-header-container\" role=\"heading\" aria-level=\"2\">\n\t\t\t\t\t<div class=\"sow-accordion-panel-header\" tabindex=\"0\" role=\"button\" id=\"accordion-label-vm-high-availability-safekits-san-less-vs-hyper-vvmware-ha\" aria-controls=\"accordion-content-vm-high-availability-safekits-san-less-vs-hyper-vvmware-ha\" aria-expanded=\"false\">\n\t\t\t\t\t\t<div class=\"sow-accordion-title sow-accordion-title-icon-left\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<header><h2 id=\"safe-vmha-diff\">VM High Availability: SafeKit's SAN-Less vs. Hyper-V\/VMware HA<\/h2><\/header>\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<div class=\"sow-accordion-open-close-button\">\n\t\t\t\t\t\t\t<div class=\"sow-accordion-open-button\">\n\t\t\t\t\t\t\t\t<span class=\"sow-icon-ionicons\" data-sow-icon=\"&#xf218;\"\n\t\t \n\t\taria-hidden=\"true\"><\/span>\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<div class=\"sow-accordion-close-button\">\n\t\t\t\t\t\t\t\t<span class=\"sow-icon-ionicons\" data-sow-icon=\"&#xf209;\"\n\t\t \n\t\taria-hidden=\"true\"><\/span>\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\n\t\t\t<div\n\t\t\t\tclass=\"sow-accordion-panel-content\"\n\t\t\t\trole=\"region\"\n\t\t\t\taria-labelledby=\"accordion-label-vm-high-availability-safekits-san-less-vs-hyper-vvmware-ha\"\n\t\t\t\tid=\"accordion-content-vm-high-availability-safekits-san-less-vs-hyper-vvmware-ha\"\n\t\t\t\tstyle=\"display: none;\"\t\t\t>\n\t\t\t\t<div class=\"sow-accordion-panel-border\">\n\t\t\t\t\t<article><header>\n<h3>What is the difference between SafeKit VM High Availability and Traditional Shared Storage Clusters (Hyper-V Cluster and VMware HA)?<\/h3>\n<\/header>Choosing the right Virtual Machine (VM) High Availability (HA) solution is critical for maintaining business continuity. IT organizations often face a primary architectural choice: utilizing traditional HA clusters, which require expensive Shared Storage like a Storage Area Network (SAN), or adopting modern, software-based solutions that eliminate this dependency. This comparison provides a detailed breakdown of the key differences between the diskless, real-time replication approach of SafeKit (using its Hyper-V and KVM modules) and the classical shared-disk clustering architectures typified by Microsoft Hyper-V Cluster and VMware HA.\n<div class=\"table-container-mobile\">\n<table class=\"border vertical-middle horizontal-center\" width=\"100%\"><caption>Architectural Comparison: SafeKit Non-Shared Storage HA vs. Traditional SAN-Based Clusters<\/caption>\n<thead>\n<tr>\n<th style=\"width: 50%;\" scope=\"col\">SafeKit (with Hyper-V or KVM Module)<\/th>\n<th style=\"width: 50%;\" scope=\"col\">Microsoft Hyper-V Cluster &amp; VMware HA (Traditional)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><img decoding=\"async\" src=\"https:\/\/www.evidian.com\/wp-content\/smush-webp\/2022\/07\/vm-replicated.png.webp\" alt=\"Diagram showing SafeKit VM HA synchronous replication between two Hyper-V\/KVM hosts without requiring a shared disk or SAN.\" width=\"200\" \/><\/td>\n<td><img decoding=\"async\" src=\"https:\/\/www.evidian.com\/wp-content\/smush-webp\/2023\/03\/vm-shared-disk.png.webp\" alt=\"Diagram illustrating traditional VM HA cluster architecture, such as VMware or Hyper-V Cluster, requiring a central shared disk (SAN) for failover.\" width=\"200\" \/><\/td>\n<\/tr>\n<tr>\n<td>No shared disk required - uses <a href=\"\/products\/high-availability-software-for-application-clustering\/synchronous-replication-vs-asynchronous-replication\/\">synchronous real-time replication<\/a> instead, ensuring no data loss.<\/td>\n<td>Requires shared disk and a specific external disk bay (SAN).<\/td>\n<\/tr>\n<tr>\n<td>Supports Remote Sites without requiring SAN replication across locations.<\/td>\n<td>Remote sites typically require replicating disk bays across a complex SAN setup.<\/td>\n<\/tr>\n<tr>\n<td>No specific IT skill is required to configure the system (using <a href=\"\/products\/high-availability-software-for-application-clustering\/hyper-v-replication-automatic-failover-load-balancing\/safekit-quick-installation-guide-with-hyper-v\/\">hyperv.safe<\/a> and <a href=\"\/products\/high-availability-software-for-application-clustering\/linux-kvm-high-availability-replication-automatic-failover-load-balancing\/safekit-quick-installation-guide-with-kvm\/\">kvm.safe<\/a>).<\/td>\n<td>Requires specific, high-level IT skills to configure the cluster and SAN infrastructure.<\/td>\n<\/tr>\n<tr>\n<td>Note that the Hyper-V\/SafeKit and KVM\/SafeKit solutions are limited to replication and failover of 32 VMs.<\/td>\n<td>Note that the Hyper-V built-in replication (Hyper-V Replica) does not qualify as a high availability solution. This is because the replication is asynchronous, which can result in data loss during failures, and it lacks automatic failover and failback capabilities.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h4>Conclusion: Why SafeKit's SAN-Less HA is a Modern Alternative<\/h4>\nThe core difference lies in the reliance on shared storage. SafeKit's approach uses synchronous data replication directly between servers, ensuring a zero data loss (RPO=0) scenario and dramatically simplifying deployment by eliminating the need for expensive SAN hardware and specialized storage skills. While traditional clusters provide robust features, the high complexity, high cost, and shared-disk dependency make them less flexible, especially for remote or multi-site deployments.\n\nFor organizations prioritizing cost-effectiveness, simplicity, and fast deployment of VM High Availability without investing in complex storage infrastructure, SafeKit's SAN-less model provides a superior and modern alternative.\n\n<\/article>\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t<\/div>\n\t\t<\/div>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div><div
