🧵 Understanding Tentacle: How Erasure Coding Gets a Performance Boost
If you work with distributed storage, you've probably heard about erasure coding's I/O amplification problem. Tentacle solves it with 3 key innovations: PARTIAL READS
Instead of reading entire chunks, Tentacle reads only the data blocks it needs. This dramatically reduces unnecessary I/O and improves random read latency—critical for VM workloads.
PARTIAL WRITES
Traditional erasure coding requires reading a full stripe, merging writes, and recalculating all parity shards. Tentacle changes the game: modify only the affected chunk and update only the necessary parity shards. Fewer rewrites = better throughput.
PARITY DELTA WRITES
Optimize parity calculations at the block level, eliminating redundant operations and further reducing write amplification.
The Result? Tentacle matches or exceeds 3x replication performance while maintaining the storage efficiency benefits of erasure coding.

One ransomware attack can shut down an entire business in minutes.
No files. No access. No time to react.
That’s why we built SnapShield a ransomware-activated fuse for your storage environment. ⚡🔒
Using real-time behavioral analysis, SnapShield detects ransomware activity and instantly isolates the infected client before the attack can spread.
The infected system gets cut off. Everyone else keeps working.
No unnecessary downtime. No full-environment shutdown.
Just smarter ransomware protection built the 45Drives way.

What happens if ransomware hits your mission-critical data tomorrow?
For most organizations, the answer is downtime, recovery costs, and operational disruption.
That’s why we built SnapShield.
SnapShield runs directly on the storage server and monitors file activity in real time. When ransomware-like behavior is detected massive encryption events, abnormal write activity, sudden file changes SnapShield can immediately isolate the infected machine and stop the attack from spreading across the rest of the environment.
Instead of:
• Days restoring backups
• Company-wide downtime
• Critical workflows offline
You contain the incident before it becomes catastrophic.
For organizations with mission-critical data, ransomware protection needs to happen at the storage layer not after the damage is already done.

In traditional setups, accessing remote block storage often requires iSCSI.
With DRBD diskless mode, clients can attach to a DRBD resource directly—without local disks—while all writes are replicated across nodes in real time.
