Solution Brief: SANless Cluster Solutions for Virtual Server Environments
SIOS SANless software lets you build a cluster in a virtualized environment without the need for shared storage. You can use any local storage types available and provided by the hypervisor. SIOS software uses efficient block-level replication to keep local storage synchronized, enabling the standby servers in your cluster to continue to operate after a failover with access to the most recent data.
Cluster virtual machines
SIOS SANless software lets you create a cluster using virtual machines sitting on top of any hypervisor (VMware, Xen, Microsoft Hyper-V, and others). It uses real-time replication to synchronize storage on the primary VM with storage on a standby VM located in the same data center, in your disaster recovery site, or both. In the event of a disaster, the standby VM can be brought into service immediately, eliminating the hours needed for restoration from back-up media. You simply access the replicated VMs in the DR site directly.
Hyper-V host clustering that supports Live Migrations
In Microsoft Hyper-V environments, SIOS SANless software allows you to cluster entire Hyper-V host machines at the hypervisor level for complete VM portability and failover protection. By keeping a real-time copy of the running VM synchronized on an alternate Hyper-V host, SIOS software allows you to easily failover or Live Migrate a VM from one Hyper-V host to another. You get complete portability to move individual VMs or all of the VMs on a host to another Hyper-V host in the cluster.
Build a SIOS SANless cluster using virtual servers (A). In Microsoft Hyper-V environments (B), SIOS SANless clusters can be used at the virtual machine level for easy Live Migrations and complete server portability.
Easy disaster recovery testing
SIOS software also lets you restore replicated VMs to perform disaster recovery testing without disruption to the production site. When testing is complete, SIOS software eliminates changes that were made on the target server during the testing and resumes the replication from where it stopped.
