Redis is one of the fastest in-memory data stores, powering caching, session management, message queues, and real-time analytics. By design, it delivers microsecond response times. But here’s the trade-off: when persistence is enabled with RDB snapshots or AOF logs, Redis performance suddenly depends on the speed of the underlying storage. On standard disks, this creates slowdowns, recovery delays, and replication lag.
Simplyblock changes that. With NVMe-over-TCP, zone-resilient volumes, and instant scalability, Redis gets the persistence it needs without sacrificing the in-memory speed it’s known for.
Redis Performance Breaks When Persistence Meets Storage
Redis runs at memory speed, but durability lives on disk. Persistence with RDB and AOF generates heavy write activity. If storage is slow, you’ll see latency spikes, longer recovery times after restarts, and unstable replication under load. For applications that rely on Redis for real-time workloads, these issues aren’t minor inconveniences — they’re critical risks.
Simplyblock solves this with NVMe-over-TCP storage. It delivers sub-millisecond latency, consistent throughput, and the ability to scale volumes on demand, so Redis persistence no longer drags down your performance.
🚀 Use Simplyblock with Redis for Speed + Reliability
Keep Redis fast with NVMe-backed storage, instant snapshots, and cross-zone durability.

Step 1: Set Up a Simplyblock Volume for Redis Data
Start by creating a simplyblock volume with the CLI and mounting it to store Redis persistence files:
sbctl pool create –name redis-pool
sbctl volume create –pool redis-pool –size 50Gi –name redis-data
mkfs.ext4 /dev/simplyblock/redis-data
mount /dev/simplyblock/redis-data /var/lib/redis
With Redis data and AOF logs backed by simplyblock, you remove the usual bottleneck and gain zone-independent durability from day one.
For more on configuring storage for optimal Redis performance, check the Redis Persistence Configuration Guide.
Step 2: Enable AOF or RDB Without Sacrificing Speed
Redis users often disable AOF or rely only on RDB snapshots to avoid storage overhead. But that means trading away durability. With simplyblock, you don’t need to make that compromise.
Point your Redis config to the mounted volume, enable appendonly yes, and Redis writes will remain lightning fast. Persistence stays on, recovery is reliable, and workloads don’t slow down. It’s durability without the performance penalty.
To optimize for high throughput and minimal impact on performance, see the Redis Configuration.
Step 3: Expand Storage for Growing Redis Clusters
AOF files and Redis datasets grow quickly — especially in clustered setups. Running out of space forces downtime or manual migrations on traditional volumes.
With simplyblock, you can resize a Redis volume while it’s online:
sbctl volume resize –name redis-data –size 100Gi
resize2fs /dev/simplyblock/redis-data
No restart. No downtime. Perfect for scaling Redis on Kubernetes or clustered deployments where availability matters most.
Step 4: Keep Redis Highly Available Across Zones
High availability is a core part of Redis Sentinel and Cluster setups. But if your storage is locked to a single zone, failover gets messy — or worse, fails outright.
Simplyblock volumes are zone-independent. If a Redis node is rescheduled or fails over into a different zone, the volume stays accessible with no reattachment headaches. That makes multi-zone HA seamless and aligns perfectly with multi-availability zone disaster recovery strategies.
For detailed information on setting up Redis Sentinel for high availability, refer to the Redis Sentinel Documentation.
Step 5: Add Storage-Level Replication for Safer Redis Data
Redis replication keeps data copies in memory, but it doesn’t protect you at the storage layer. With simplyblock, you can enable real-time block-level replication for an extra layer of safety.
sbctl volume replicate –volume-id=redis-data –target-zone=eu-west-b
This works alongside Redis replication, giving you double protection. If a node or zone goes down, you have both in-memory replication and durable storage replication to keep workloads running. That’s a critical advantage for fast backups and disaster recovery.
Redis + Simplyblock – Built for Real-Time Scale
Redis is designed for speed, but persistence usually slows it down. Simplyblock fixes that with NVMe-over-TCP performance, zone-aware durability, live volume scaling, and built-in replication.
The result? Redis stays fast, persistence stays reliable, and your clusters scale without downtime. For caching, queues, and real-time analytics, Redis runs better on simplyblock — period.
Questions and Answers
Redis persistence can suffer from I/O bottlenecks when writing AOF or RDB snapshots. Simplyblock eliminates this by using NVMe over TCP, providing high throughput and ultra-low latency. This ensures Redis durability without slowing down in-memory operations.
Yes. With software-defined storage, Redis clusters can scale horizontally while maintaining consistent persistence speed. Simplyblock distributes NVMe-backed volumes across nodes, allowing Redis to grow capacity and throughput without introducing storage bottlenecks.
Cloud block storage often adds unpredictable latency and cost overhead. Simplyblock delivers cloud cost optimization and NVMe-grade performance. For Redis, this means faster persistence, quicker failover recovery, and more predictable scaling compared to Amazon EBS or similar offerings.
Simplyblock integrates via its Kubernetes CSI driver. Redis StatefulSets can be configured with simplyblock persistent volumes, enabling high availability, durable writes, and instant scaling. This allows Redis to run production-grade persistence with minimal manual tuning.
Yes. By reducing write latency during AOF and RDB operations, simplyblock ensures Redis replicas sync faster and recover more quickly after restarts or node failures. Combined with database performance optimization, this reduces downtime and ensures resilience at scale.
