SYNOLOGY | ENTERPRISE STORAGE | SA-SERIES | NAS MEMORY

Registered ECC memory for Synology SA Series — the enterprise storage arrays: SA3200D, SA3400, SA3600 and SA6400.

This is the top of Synology's range, sold into datacentre and enterprise deployments rather than offices. SA3400, SA3600 and SA6400 take registered ECC RDIMM; the SA3200D, Synology's dual-controller active-active array, takes ECC UDIMM. All DDR4-2666, from 8GB to 64GB per module.

On the SA3200D, both controllers must be populated identically. Same density, same rank, same speed. A mismatch between controllers prevents failover from working — which is the entire reason for a dual-controller array, and a failure you won't discover until the day it matters.

ECC is mandatory across the range. These arrays hold live business data under integrity guarantees that assume the memory beneath them is sound. Synology specifies ECC for every SA model, and there is no non-ECC option.

Memory here is a capacity-planning decision rather than a performance tweak: SA arrays run heavy concurrent workloads, and RAM determines how much stays cached versus how much goes back to the pool. Send us the model and current configuration and we'll spec the upgrade against what the array is actually doing.

Lifetime warranty on every module. Purchase orders, net terms and volume pricing for business, government and education buyers.
