Scale-Out Architecture
Fixed Backup Window Forever — Grow Without Forklift Upgrades
ExaGrid's unique scale-out architecture maintains a fixed backup window as data grows. Simply add appliances — each node adds processing power AND capacity simultaneously. Up to 32 appliances supporting 6 PB in a single system.
What is the Scale-Out Architecture?
Traditional backup storage forces a painful choice: as data grows, backups take longer — or you must replace the entire appliance with a larger model (a forklift upgrade). ExaGrid's scale-out architecture eliminates this dilemma entirely. Each additional appliance adds both processing power (CPU, memory, bandwidth) and storage capacity simultaneously. This means the backup window stays constant regardless of data growth — backups that took 4 hours when you had 50TB still take 4 hours when you have 500TB. Up to 32 appliances can be combined in a single system supporting 6 PB of full backup capacity. Expansion is non-disruptive — add a node while backups are running with zero downtime. Multi-site deployments support up to 16 locations in a single group with 50:1 WAN-efficient replication. DR options include AWS, Azure, and third-party colocation facilities.

How the Scale-Out Architecture Benefits Your Organization
Real, measurable advantages that translate into operational efficiency, cost savings, and risk reduction.
Predictable Backup Windows Forever
As data grows, traditional appliances slow down. ExaGrid adds processing power with every node — keeping backup times constant from 50TB to 6PB.
Grow Without Disruption
Add an appliance while backups are running. No downtime, no migration, no reconfiguration — just plug in and expand. Your operations never miss a beat.
Pay-As-You-Grow Economics
Buy what you need today, expand incrementally as data grows. No over-provisioning, no forklift upgrades, no wasted capital on unused capacity.
Multi-Site Simplicity
Manage up to 16 locations from a single console. 50:1 WAN-efficient replication means remote offices back up to headquarters without saturating internet links.
Cloud DR Without Complexity
Replicate to AWS, Azure, or colo facilities with bandwidth throttling and WAN encryption. Cloud DR that actually works — without cloud storage sticker shock.
One Console, Complete Visibility
Centralized management shows all appliances, all sites, and all replication status from a single interface — no logging into multiple systems.
Challenges We Solve
Every product in our portfolio addresses specific operational pain points. Here is how the Scale-Out Architecture solves yours.
As backup data grows, traditional appliances take progressively longer to complete backups — eventually missing their window entirely.
ExaGrid's scale-out architecture adds processing power with every node. The backup window stays fixed regardless of data growth — from day one to year ten.
Capacity upgrades require replacing the entire appliance — a forklift upgrade that is expensive, disruptive, and wastes the old hardware.
Simply add a new ExaGrid appliance to the existing cluster. The old appliances keep working, the new one adds capacity and performance — no replacement, no waste, no downtime.
Multi-site organizations struggle with slow, expensive WAN replication that saturates internet connections and creates backup bottlenecks.
50:1 WAN-efficient deduplication means only unique data crosses the WAN. Replicate 50TB of changes using just 1TB of bandwidth — making multi-site backup practical and affordable.
Cloud DR solutions charge exorbitant egress fees and storage costs, making cloud-based disaster recovery financially unsustainable.
ExaGrid replicates to AWS/Azure using deduplicated data — minimizing cloud storage costs. Bandwidth throttling prevents internet saturation. Cloud DR without the cloud cost shock.
