SvSAN Features

What exactly are you getting by choosing SvSAN?

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.

SvSAN is available in two versions, Standard Edition and Advanced Edition.

Standard Edition includes everything that you need in a software-defined storage solution to configure low-cost, highly available infrastructure.

Advanced Edition provides highly sophisticated features such as Predictive Storage Caching which utilizes patent-pending algorithms to unleash the full power of memory and hybrid disk configurations. It also includes Data Encryption which delivers military-grade security and eliminates the need for expensive OS or hypervisor-level encryption.

Standard Edition features:

Explore the features that are included in SvSAN Standard Edition.
  • 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
  • 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

Advanced Edition features:

Explore the features that are only available in SvSAN Advanced Edition.
  • 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.
  • Utilizes a FIPS 140-2 compliant algorithm (XTS-AES-256) to deliver military-grade encryption to all data handled by SvSAN or just selected volumes
  • Allows secure erasure and re-key
  • Compatible with any KMIP-compliant key management system
  • Read more about SvSAN's data encryption features in the dedicated white paper.

Predictive Storage Caching

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 - learn more about it here.

Data Encryption

StorMagic introduced data encryption in SvSAN 6.2, thus enabling organizations to benefit not only from an incredibly lightweight architecture, but also from highly secure data, encrypted using military-grade, FIPS 140-2 compliant algorithms.

“We needed a cost-effective solution with data replication features, allowing us to access and share critical data at all times. This information needed to be secure as it involved confidential patient records. We found StorMagic SvSAN to be a good solution with an attractive price.”

Antoine Lagarde | Senior IT Technical | Centre Hospitalier Pierre Oudot

"We’ve implemented a future-proof virtual SAN that offers high performance, availability and scalability to grow with us as our needs change over time. The solution is easy to use and affordable without compromising features. SvSAN has everything I need, and more.”
