Game-changing features that meet your specific needs

StorMagic SvSAN has been designed to be as simple and lightweight as possible, while delivering everything you need to eliminate downtime and provide high performance and high availability at one to thousands of locations.

All of the features necessary for highly available shared storage are included in the base SvSAN license. It enables the configuration of low-cost, software-defined storage infrastructure.

There are also two performance- and security-enhancing add-ons available, which are SvSAN’s caching and data encryption features.

SvSAN’s performance-enhancing caching features are collectively known as Predictive Storage Caching, which utilizes patent-pending algorithms to unleash the full power of memory and hybrid disk configurations.

SvSAN’s data encryption feature enables organizations with one to thousands of locations to affordably and efficiently introduce data encryption at each individual site.

SvSAN features:

  • Data is written to two SvSAN VSA nodes to ensure service uptime.
  • Write operations only complete once acknowledged on both SvSAN VSAs.
  • In the event of a failure, applications are failed over to other available resources.
  • Separate nodes geographically to provide an added layer of resiliency
  • Different racks, separate rooms or buildings, or even across an entire city
  • Read more about the stretch cluster feature in the dedicated white paper.
  • Transparently and non-disruptively migrate volumes from one storage location to another
  • Simple and mirrored volumes can be migrated between storage pools on the same SvSAN VSA node or to another SvSAN VSA node entirely
  • Read more about the volume migration feature in the dedicated white paper.
  • Automates the recovery process of an SvSAN VSA node following a server failure or replacement
  • SvSAN VSA configuration changes are tracked and stored on another SvSAN VSA in the cluster
  • Mirror targets are rebuilt and resynchronized, enabling a quick return to optimal service
  • Simple targets can be automatically recreated, ready for data recovery from backup
  • Accelerating VMware I/O operations by offloading them to SvSAN
  • Supports the Write Same and Atomic Test & Set (ATS) primitives
  • Monitor and manage SvSAN from a single location with multiple options including WebGUI
  • Seamless integration with vCenter Web Client enabling alerts to be forwarded and captured on one screen
  • Email alert notifications using SMTP, and SNMP integration with support for v2 and v3
  • Easily deploy containers at the edge with persistent, highly available storage
  • No additional costs to deploy containers in an SvSAN cluster
  • One platform at the edge for VMs, containers, or both
  • Read more about the CSI driver in the dedicated white paper.
  • Deploy and upgrade VSAs through a single wizard either immediately or in a staged approach for out-of-hours activity
  • SvSAN handles dependencies and performs a health check ensuring there is no impact to environments
  • Provides granular, historical I/O transaction, throughput and latency statistics for each volume
  • Simple, intuitive graphical presentation with minimum, maximum, and average values for daily, monthly, yearly time periods
  • Data can be exported to CSV for further analysis
  • Acts as a quorum or tiebreaker and assists cluster leadership elections to prevent “split-brain”
  • Hundreds of locations can share a single witness and it tolerates low bandwidth, high latency WAN links
  • Supported configurations include local witness, remote shared witness or no witness
  • Read more about the witness feature in the dedicated white paper.
  • Deployments over many locations can be handled by generating a custom PowerShell script
  • Simplifies the process of upgrading multiple VSAs with full control over date/time and how many/which clusters to upgrade
  • Upgrades can be carried out on one or more SvSAN VSAs simultaneously, ensuring storage remains online throughout
  • Automated process stages the firmware, checks cluster health, then proceeds with upgrading each VSA in turn
  • Read more about this feature in this blog article
  • Install SvSAN on servers without hardware RAID controllers, such as the Lenovo SE350 and HPE Edgeline EL4000
  • Configure as RAID 0 (striping) or RAID 10 as required

Predictive Storage Caching add-on:

Explore features included in the Predictive Storage Caching add-on.

  • Beneficial to sequential read workloads – populates memory with data prior to being requested
  • Boosts performance by reducing I/O requests going to disk, instead serving data from low latency memory
  • Read more about SvSAN’s caching features in the dedicated white paper.
  • Utilizes SSDs to improve the performance of all write operations by lowering latencies and increasing the effective IOPS, resulting in faster response times, especially for random write workloads.
  • All write I/O’s are directed to the SSD allowing completion to be immediately acknowledged back to the server, at a later time the data is written from SSD to the hard disk.
  • Read more about SvSAN’s caching features in the dedicated white paper.
  • Allows data to permanently reside in memory, ensuring that data is always available in the highest performing, lowest latency cache tier, useful for frequently repeated operations such as booting virtual machines.
  • Intelligent caching algorithms identify ‘hot’ and ‘cold’ data, elevating the ‘hot’ data to the highest performing, lowest latency storage tier (SSD or memory).
  • Read more about SvSAN’s caching features in the dedicated white paper.

Data Encryption add-on:

Explore features included in the Data Encryption add-on.

  • Encrypts data before it is written to disk with a FIPS 140-2 compliant algorithm
  • Use any KMIP compliant Key Management Server, any x86 server and storage type and encrypt all data or just selected volumes
  • No need for specialist hardware, eliminates the need for OS or hypervisor-level encryption
  • Read more about SvSAN’s data encryption feature in the dedicated white paper.

SvSAN can increase IO performance by 400% while lowering the amount spent on disk drives. Predictive Storage Caching is an intelligent, automated way to optimize data placement on drives – click here to learn more.


Data Encryption

SvSAN’s data encryption feature is the most cost-effective encryption solution for storing data at the edge. It delivers FIPS 140-2 compliant encryption and eliminates the need for expensive OS or hypervisor-level solutions.
