what you get

When RAM is your most critical resource

1.5 TB of DDR5 ECC memory on a single dedicated node — no virtualisation, no memory ballooning, no NUMA misconfiguration.

1.5 TB
Up to 1.5 TB DDR5 ECC RAM

DDR5 operating at up to 5600 MT/s with ECC on every DIMM. Load entire PostgreSQL databases, Elasticsearch indices, or Redis datasets entirely in memory — zero disk I/O on hot paths.

< 80 ns
Sub-microsecond memory latency

Local DDR5 RAM delivers sub-80 ns access latency — orders of magnitude faster than any NVMe or network storage. Critical for in-memory databases, stream processors, and real-time fraud detection.

SECDED
ECC error correction

Single-error correction, double-error detection (SECDED) ECC on all DIMMs. Essential for financial and healthcare workloads where silent data corruption is unacceptable. Memory errors are logged and reported via IPMI.

8:1
High RAM-to-core ratio

Configured with an 8:1 GB-to-core ratio (e.g., 1,536 GB RAM / 192 cores) to ensure your in-memory workloads aren't CPU-bound. More memory per thread means fewer cache evictions and higher hit rates.

10 Gbps
10 Gbps dedicated uplink

All High-Memory servers come with a 10 Gbps uplink for high-throughput replication, bulk data ingestion, and low-latency read traffic. Private VLAN available for cluster interconnects.

7 GB/s
NVMe persistence layer

Local NVMe drives provide fast persistence for write-ahead logs, RDB snapshots, and overflow. When RAM isn't enough, NVMe is 10× faster than network-attached storage for overflow and swap.

High-Memory configurations

From 192 GB to 1.5 TB of DDR5 ECC RAM on a single node. All include NUMA topology, ECC logging, and IPMI out-of-band access.

Who runs on High-Memory servers

In-Memory Databases

Run Redis, Memcached, or SAP HANA with the full dataset in RAM

When your entire working dataset fits in memory, query latency drops from milliseconds to microseconds. High-Memory servers let you run Redis clusters, Memcached pools, or SAP HANA in-memory analytics without the cost of cloud in-memory tiers.

Real-Time Analytics

Sub-second BI queries over billion-row datasets

ClickHouse, Apache Druid, and StarRocks dramatically outperform when data fits in memory. With 1.5 TB RAM, you can keep months of time-series data hot — enabling dashboard queries that return in under 100 ms.

Java / JVM Workloads

Stop tuning heap limits — give your JVM all the memory it needs

Elasticsearch, Kafka brokers, Hadoop NameNodes, and large Spring Boot applications all benefit from massive heap sizes. High-Memory servers eliminate the root cause of OutOfMemoryError crashes and GC pause storms.

Frequently asked questions

All High-Memory servers use DDR5 RDIMM (Registered DIMM) at 4800–5600 MT/s depending on configuration. ECC is enabled by default on all DIMMs. DDR5 delivers ~50% higher bandwidth than DDR4 at the same frequency.
High-Memory Dedicated

1.5 TB of RAM. All yours.

The only way to get true in-memory performance is to own the hardware. No memory ballooning, no balloon drivers, no memory overcommit — just raw DDR5 bandwidth at your disposal.
