High Availability
eEVOS Plus ensures that you can access your virtual machines (VMs) even in the event of a complete server failure. While standard virtualization servers offer redundant features like RAID or UPS, eEVOS goes a step further by mirroring VMs to guarantee high availability.
One Contact for Everything
Many virtualization solutions require you to deal with multiple vendors and points of contact:
- Virtualization
- Storage
- Backup
With eEVOS, you get everything in one solution with a single support contact for all functions—simplifying support and saving time.
Professional Backup Software
Fast and reliable recovery of VMs is critical to minimizing downtime. eEVOS includes powerful, integrated professional backup software that creates reliable, deduplicated backups of your VMs. With VSS (Volume Shadow Copy Service) support, eEVOS ensures the highest possible data integrity.
Comprehensive Backup Options
eEVOS offers a range of powerful backup options designed to secure your data and ensure quick recovery. Whether you need internal backups, network-based backups, or external backups for third-party applications, eEVOS provides flexible, robust solutions.
Instant Backup & Recovery
eEVOS’s Instant Backup & Recovery feature uses Reflink technology to create backups in seconds, regardless of the VM size. Only the changed data blocks are backed up, making it fast and efficient. This allows for the recovery of entire VMs or individual files in a matter of seconds, making it perfect for environments where quick recovery is essential.
Benefits of Instant Backup & Recovery:
- Backups completed in seconds using Reflink technology
- Restore entire VMs or individual files, regardless of size
- Minimize downtime during emergencies
Network Backup
eEVOS supports deduplicated network backups to NAS (Network-Attached Storage), reducing redundant data and saving storage space. By backing up only unique data, the performance of the backup process is optimized, allowing you to efficiently back up large data volumes without impacting server performance. With network backup, you can centrally back up VMs and data, with rapid recovery over the network.
Benefits of Network Backup:
- Deduplicated backups to optimize storage space
- Centralized network backup for all VMs
- Fast recovery over the network
External Backups for Third-Party Applications
For businesses that use existing backup infrastructure or third-party backup tools, eEVOS easily integrates with external backup solutions. eEVOS creates VM snapshots that are saved in a dedicated folder, which can then be backed up using third-party tools like tape backup systems, backup software, or cloud solutions. This gives you additional redundancy and flexibility by allowing external backups to be handled by your preferred solution.
Benefits of External Backups:
- Compatibility with third-party backup solutions
- Additional redundancy with external media or cloud backup
- Flexible backup options for long-term archiving
Off-Site Disaster Recovery
eEVOS enables seamless off-site disaster recovery by allowing asynchronous replication of your VMs to remote locations. These replications can be scheduled or continuous, ensuring that your VMs are protected even in the event of a major failure. In case of a disaster, the VMs can be easily started at the remote site.
Live Migration
With eEVOS, you can migrate running VMs seamlessly between cluster nodes or even across different eEVOS installations without any downtime. Whether moving VMs between nodes, switching storage, or migrating to a new location, eEVOS offers flexible migration options.
Live Migration Includes:
- Live Migration Between Nodes: Move running VMs between different physical servers in the same cluster for hardware upgrades or maintenance without any service interruption.
- Live Storage Migration: Migrate VMs between different storage pools or disks seamlessly, with no downtime—ideal for balancing workloads or optimizing storage.
- Cross-Site Migration: Migrate VMs to a different eEVOS installation or location, enhancing your disaster recovery capabilities.
Fast and Easy Setup
eEVOS includes user-friendly wizards that help you set up a high-availability environment for your VMs in just a few clicks. The system can be monitored and managed from any network-connected computer via a browser interface. Event logging, statistics, and email alerts help you get the most out of your IT infrastructure.
Extensive Guest OS Support
eEVOS supports all major and recent operating systems, automatically optimizing each VM for the best possible performance based on the specific guest OS.
Simple Import of Existing VMs
The eEVOS Import Assistant allows you to import existing VMware, Hyper-V, or XEN images with just a few clicks. Virtual disks are automatically converted, and a new high-availability VM is created.
I/O Tuning
With eEVOS, you can set individual bandwidth limits for each VM disk and each VM network interface (NIC). This allows you to fine-tune the performance of your VMs and efficiently manage your resources.
- Total Bandwidth: Set a maximum total bandwidth that the VM can use to optimize resource allocation.
- Individual Bandwidth: Define specific read and write bandwidth limits, such as 200 MB/s for reads and 50 MB/s for writes, ensuring each VM gets the performance it needs.
Virtual Switch and Extended VLAN Support
eEVOS supports the configuration of virtual switches, allowing you to manage the network connectivity of your VMs more effectively. A virtual switch enables you to group multiple network interfaces and manage traffic flow efficiently.
Additionally, eEVOS offers comprehensive VLAN support, enabling you to segment your network securely. You can configure multiple VLANs on a single switch, ensuring secure traffic separation between different VMs and network segments.
Shared Storage (Shared Drive)
eEVOS supports shared storage configurations where both servers access a centralized external storage device connected via SAS, iSCSI, or Fibre Channel. This architecture allows you to store all VMs centrally, ensuring that both servers share the same data.
If one server fails, the remaining server automatically takes over the VMs, ensuring no downtime. Shared storage simplifies storage management while providing a scalable solution for businesses looking to centralize their storage resources while maintaining high availability.
Mirror Your Virtual Machines Between Servers
With eEVOS Plus, high availability is ensured through real-time data replication and synchronization between two mirrored servers. Both servers contain identical VM data, so if one server fails, the other node can instantly start the VMs. You can also define which VM should run on which server, optimizing server utilization and boosting performance.
Benefits of Shared Storage:
- Centralized management and storage of all data and VMs
- Automatic failover in the event of a server failure
- Flexible connections via SAS, iSCSI, or Fibre Channel
- Scalability: Multiple servers can access the same storage simultaneously without impacting performance
Thin Provisioning
Thin Provisioning allows you to save storage costs by allocating physical disk space only for the portions of the VM that are actually used. This maximizes storage efficiency and reduces costs.
Cluster-Aware VM Snapshots
eEVOS allows you to take VM snapshots on any node, even if the file is being used by another node. You can create snapshots of your VMs and run them on a different node than the original VM host, enhancing flexibility.
VM Cloning
eEVOS allows you to clone VMs from snapshots and run them immediately on a different node, improving the flexibility of your environment.
Hardware RAID Support
eEVOS supports a wide range of hardware RAID controllers from various manufacturers. eEVOS also includes an integrated RAID management tool and email notifications for hardware issues. The LSI Storage Management Agent is also included for easier RAID management.
Software RAID Support
eEVOS offers a cost-effective redundancy solution with support for all major RAID levels (RAID 0, 1, 10, 5, 6). It also supports online capacity expansion, hot spare drives, and email notifications in the event of a disk failure.
UPS Support
In the event of a power failure, eEVOS automatically shuts down the server when the UPS battery is low. You will be notified by email if a power failure occurs. eEVOS supports both network and USB UPS devices.
Network Bonding
eEVOS allows you to combine network interfaces for failover redundancy or increased throughput, improving your network resilience and performance.
VLAN Support
eEVOS supports VLAN networks, allowing you to efficiently segment your network traffic and ensure security by isolating traffic between different VMs and network segments.
