A resilient storage foundation.
Across your cloud services.
Cloud IaaS, PaaS and resource pools use a central storage cluster operated by Ruk-Com. Customer-specific volumes and access permissions keep workloads separated on shared infrastructure.

Self-healing: copy a healthy replica to a reserve node
Example after scale-out: X / Y / Z / W are different chunks · each has 3 copies across 3 nodes.
Metadata & cluster control · Manages data placement, node health and replica policy separately from the data path.
01 / DISTRIBUTED WRITE
Three replicas protect your data
Each data chunk has three copies on separate storage nodes under a failure-domain policy. If one disk or node fails, copies remain on other nodes.
The customer sees the volume’s capacity; replica storage is managed at cluster level.02 / HEALTHY READ PATH
Read from an available replica.
The client uses metadata to locate data and reads from an available storage node. This view highlights one read path; every request does not need all replicas.
Requests across workloads can use the cluster’s distributed resources.03 / DETECT → RECOVER
Self-healing restores protection
When node B fails in this example, the cluster uses healthy copies and rebuilds a replica on node D to restore three-copy protection.
Rebuild requires healthy nodes and sufficient spare capacity. Detection and recovery time depend on policy, networking and the current workload.2 / 3 replicas · Rebuilding a replacement3 / 3 replicas · Replacement ready
04 / ADD → REBALANCE
Scale out capacity and aggregate I/O
Add storage nodes and disks to increase capacity and aggregate I/O resources. Data is rebalanced under the placement policy while each chunk retains three replicas.
Four nodes do not mean four replicas per chunk: multiple chunks are distributed across the cluster.Architecture simulation · Timing is compressed to show the sequence

Storage tiers
Match SSD / NVMe options and storage tiers to the workload, from latency-sensitive transactions to steadily growing data.
Replication network
Plan bandwidth for client I/O, replication and rebuild traffic, reducing bottlenecks between nodes.
Distributed I/O
Nodes share the workload. Expanding the cluster adds capacity and resources for aggregate I/O.
Workload-based sizing
Evaluate read/write patterns, block size and queue depth alongside latency to size resources for real application demand.
Scale capacity + performance · Add nodes to grow capacity and aggregate I/O, with hardware, networking and volume policies aligned to your system’s requirements.
PROTECTION / IN DEPTH
Layered protection
for business-critical data.
Confidence starts with available data copies and a recovery plan matched to business risk. Combine three replicas, access controls and backup / DR within the agreed service scope.
3 replicas & failure isolation
Store three copies on separate storage nodes to preserve data through individual hardware failures, with replica health tracked against policy.
Self-healing & recovery
The cluster automatically rebuilds replicas when resources are available. Our team monitors rebuild progress, capacity and I/O load, which can temporarily affect performance.
Access control & isolation
Separate customer volumes and permissions through cloud services, with administrative and network access scoped to the users who need it.
Backup & recovery
Define backup policies and recovery points under the selected service to address accidental deletion, application-level corruption and the need to restore earlier data.
Plan your business continuity
Define RPO—the maximum acceptable data-loss window—and RTO—the target time to restore the agreed service level. Plan backup, retention and DR around critical systems, with scope and agreed objectives confirmed for each project.
SCALE / WITH YOUR BUSINESS

STORAGE / ANSWERS
Enterprise storage.
Questions that matter.
For IT teams and decision-makers assessing data protection, performance and recovery before deployment.
How is block storage different from object storage?
Block storage provides disks or volumes for VMs, databases and applications. Object storage exposes objects through APIs such as S3. Choose by access pattern, not just data size.
How do three replicas protect data, and is backup still needed?
Three replicas keep current data on separate nodes to reduce hardware-failure risk. Deletions and incorrect writes can propagate to every copy. Backups retain historical data for recovery from accidental deletion or application issues. Plan both together, with backup policies and retention matched to the importance of your data.
How far can capacity and performance scale?
Scale-out adds nodes and disks within platform limits, increasing capacity and aggregate I/O resources. Per-volume size and performance depend on quotas, hardware, networking and workload.
What does volume expansion involve?
Check the service and guest OS capabilities. Some systems require partition or filesystem expansion after a volume grows. Our team helps plan the steps and any impact.
How is data protected during a node failure?
The cluster uses healthy copies and rebuilds missing replicas when resources are available. If a chunk falls below the configured minimum-replica count, writes to that affected data are suspended until the threshold is restored. Availability depends on replica health and cluster policy.
How can we plan encryption and disaster recovery?
Our team helps assess encryption, key ownership, key management and cross-site recovery requirements, alongside backup retention and a restore-validation plan. Supported technology, enabled services and responsibilities are confirmed before the project begins.
What should we prepare for an enterprise storage assessment?
Share your cloud service, application / database type, data volume, growth rate and latency / IOPS / throughput targets, together with backup, retention, RPO / RTO and support requirements.
