Databases form the backbone of business-critical applications with high demands on memory bandwidth, storage latency and availability. At IT-RESELL.COM, you can find database servers from HPE, DELL, Lenovo and Fujitsu that are precisely tailored to your database system: plenty of RAM, fast NVMe storage and well-designed redundancy – available as certified refurbished systems or brand-new equipment.

Technical requirements for database servers in detail
Populate all channels for maximum bandwidth. For in-memory databases, the data set must fit entirely into RAM.
High memory bandwidth and – in the case of core-based licensing – a carefully selected number of cores. A small number of fast cores can be more cost-effective in terms of licensing.
NVMe with high IOPS and low latency. Separate volumes for data, logs and TempDB. RAID for redundancy.
10/25 GbE for high throughput during replication and in Always-On/Data Guard clusters.
Redundant power supplies, hot-plug drives, ECC RAM. For HA: two servers with database clustering.
iDRAC, iLO, XClarity or iRMC for remote maintenance and automated monitoring.
Supported database systems
SAP HANA · Microsoft SQL Server · Oracle Database · PostgreSQL · MySQL / MariaDB – we advise on the appropriate hardware for each system.
Our hardware recommendations for databases
| Scenario / Requirement | Recommended systems | Configuration recommendation |
|---|---|---|
| Medium-sized OLTP database (SQL / PostgreSQL) | DELL R650/R750 · HPE DL380 Gen 11 · Lenovo SR650 V3 · Fujitsu RX2540 M8 | 256–512 GB RAM, NVMe RAID, separate volumes for data and logs |
| SAP HANA / In-Memory | DELL R750 · HPE DL380 Gen 12 · Lenovo SR650 V3/V4 | Very high RAM capacity, all slots populated, certifiable configuration |
| Licence cost-optimised (Oracle/SQL) | DELL R660 · HPE DL360 Gen 11 | Few, fast cores + plenty of RAM/NVMe – reduces core-based licence costs |
| HA pair (Always On / Data Guard) | 2× DELL R750 or HPE DL380 | Identical servers, 25 GbE replication, automatic failover |
| Cost-optimised (refurbished) | DELL R740xd/R640 · HPE DL380 Gen 10 · Lenovo SR650 V2 | Very cost-effective for open-source databases and stable workloads |

As a Dell and Lenovo partner, we receive particularly attractive terms on a project-by-project basis – it’s well worth making a direct enquiry, especially for HA pairs and database projects.
Specific use cases
ERP / SAP backend
An HPE or DELL server with high RAM capacity, serving as a certified SAP HANA platform, stores the entire dataset in memory – for maximum analysis speed.
High-availability SQL database
Two identical Lenovo servers form an SQL Always-On pair – if one node fails, the second automatically takes over without any data loss.
PostgreSQL on refurbished hardware
A licence-free PostgreSQL database runs at high performance on a refurbished DELL server with NVMe – offering excellent value for money.
Extended life cycle · lower carbon footprint
Why refurbished servers make sense for this application
For open-source databases and stable workloads, refurbished servers are an excellent choice. The money saved can be invested in additional NVMe storage, more RAM or a second server for high availability.

Frequently Asked Questions
The entire data set must fit entirely into the RAM, plus a reserve. Depending on the size of the database, this can be several GB or TB. We determine the required capacity based on the size of your database.
It’s crucial: NVMe SSDs with high IOPS and low latency. Data, logs and temporary areas should be stored on separate, redundant volumes.
With core-based licensing, a small number of fast cores with plenty of RAM and NVMe can be more cost-effective than a large number of cores. We advise on the optimal CPU choice to minimise licensing costs.
For true high availability, yes: with two servers and mechanisms such as SQL Always On or Oracle Data Guard, the second node automatically takes over in the event of a failure.
They’re very well suited to open-source databases and stable workloads. The money saved can be invested in storage, RAM or an HA partner.
SAP HANA requires certified configurations. When designing the system, we ensure a suitable, certifiable platform and hardware configuration.
