StoneFly ISC™ & Voyager™
Choose the SAN architecture that matches your uptime requirement.
StoneFly SAN is organized around two deployment families: single-node Integrated Storage Concentrator (ISC™) appliances and Voyager™ high availability SAN systems. Both deliver enterprise block storage; the right choice depends on uptime requirements, workload criticality, and growth plans.
ISC™
ISC™ Single-Node SAN
Turnkey iSCSI or optional Fibre Channel SAN appliance with integrated storage controller, hardware RAID, and high-speed drives.
- Integrated Storage Concentrator architecture
- Available as iSCSI or optional Fibre Channel
- Designed for SMB, SME, branch, and enterprise workloads
- Expansion arrays support growth over time
Voyager™
Voyager™ HA SAN Systems
High availability SAN architecture with two clustered storage controller nodes and one or more HA RAID arrays.
- Automated failover and failback
- Built for workloads that cannot tolerate unplanned downtime
- Modular controller and RAID array design
- Expansion arrays support petabyte-scale growth
Built for critical shared storage: SAN volumes often support databases, virtual machines, and business applications that cannot tolerate unreliable storage. StoneFly SAN systems combine performance, protocol flexibility, scalable capacity, and resilience features so teams can support demanding workloads with confidence.

DCIG Top 5 Midmarket SDS Block Storage 2025–2026
StoneFly iSCSI and Fibre Channel SAN was named a Top Midmarket SDS Block Storage Solution by DCIG, spotlighting features including variable block deduplication, immutable snapshots, thin provisioning with space reclamation, and encryption.
SAN storage management
Built-in features for block storage performance, efficiency, and recovery.
Manage iSCSI volumes, monitor resource health, and configure storage optimization and data protection services through StoneFusion™ SAN OS.
Deduplication
Remove redundant copies and reduce storage consumption with variable block deduplication, with ratios up to 100x depending on data type and workload.
Thin Provisioning
Provision storage efficiently, reclaim unused space, and allocate capacity as new databases, applications, and projects grow.
FlashCache™
Use high-speed NVMe SSDs for SSD caching to support high-IOPS workloads and improve performance for demanding structured data.
Sync & Async Replication
Configure multi-appliance and multi-location replication, including synchronous replication for iSCSI campus mirroring.
Encryption
Protect critical structured workloads with optional hardware-enabled volume encryption for data at rest.
Immutable Snapshots
Set up delta-based mountable snapshots for critical workloads and recover to a known point after errors, corruption, or disaster events.
Enterprise SAN problems
Solve the practical block-storage problems buyers actually evaluate.
Enterprise SAN buyers need storage that can keep pace with application demand, reduce downtime risk, scale with data growth, and simplify day-to-day management. StoneFly SAN appliances are designed to address these priorities with dedicated block storage hardware and StoneFusion™ SAN OS services.
Performance
Critical workloads need predictable I/O
Databases, virtual infrastructure, and transactional applications need dependable block storage with caching, high-speed networking, and purpose-built storage processing.
Availability
Storage outages cascade into application outages
When shared SAN storage fails, the dependent databases, applications, and VMs are impacted. Voyager™ addresses this with clustered HA architecture.
Scale
Capacity must grow without a forklift refresh
StoneFly SAN deployments can expand from terabytes to petabytes with external expansion arrays and custom-built configurations.
Operations
Storage services need unified management
StoneFusion™ SAN OS centralizes volumes, monitoring, reporting, replication, snapshots, caching, and security controls.
Air-gapped and immutable storage options
Resilience features for SAN-hosted workloads and recovery points.
Protect the critical workloads running on your SAN with integrated security and ransomware protection features designed to help reduce data-loss risk and support faster recovery. StoneFly SAN appliances include options such as patented Air-Gapped Vault® and immutability, volume deletion protection, encryption, access controls, and protected storage for databases, VM datastores, and application data.
Immutable Snapshots
Protect point-in-time recovery data from overwrite during the retention window and restore volumes after operational errors or destructive events.
Volume Deletion Protection
Reduce accidental or malicious deletion risk by adding controls that protect critical SAN volumes from unauthorized removal.
MFA & Admin Controls
Strengthen administrative operations with multi-factor authentication and stronger access-control practices for storage management.
Encryption
Use optional hardware-enabled volume encryption to protect data at rest on critical block storage volumes.
Air-Gapped Storage Options
Use policy-based isolation for designated protected data or recovery points where disconnected storage is required.
Malware Scanning Options
Support additional detection and recovery workflows with integrated scanning and protected storage options where applicable.
Layered resilience for critical data: StoneFly SAN systems can combine snapshots, replication, encryption, access controls, and protected storage options to help organizations reduce data-loss risk and recover faster from operational issues or destructive events.
