Lenovo ThinkSystem ST550 supply

About this model

The ThinkSystem ST550 is the tower anchor of our Lenovo listings, published under type code 7X10A0B3NA in two configurations — a Xeon 6240 build and a Xeon 3204 build. The two listings bracket the model's working range: a department's real server, and the same chassis as a quiet infrastructure box.

Configuration choices

That bracket is the ST550's story. The 6240 configuration is a proper departmental host — virtualisation for a branch, a line-of-business application, a file and print estate with headroom. The 3204 build is the entry point: backup target, infrastructure services, the first server a growing office buys. Same tower, honest spread.

Tower buying adds two questions rack buying does not: acoustics (it will sit near people) and physical security (it will not sit in a locked hall). Both belong in the inquiry; both shape the final build.

Where it fits

Buyers put this model to work in three recurring patterns:

• Branch and departmental hosts in the 6240 configuration.
• First-server and infrastructure duty in the 3204 configuration.
• Sites standardised on ThinkSystem that need one tower.

In service

A tower server's operations are office operations, and the ST550's ownership pattern reflects its habitat: it sits near its users, often without a dedicated administrator, and must be boring at close range. That means acoustics and thermals in a normal room, a backup routine that runs without being watched, and remote management enrolled from day one so that whoever supports it rarely has to visit it.

The two listed configurations diverge most in their service expectations. The 3204 build's jobs — backup, file, infrastructure — forgive a maintenance window; the 6240 build hosting a department's virtual machines does not, and its ownership should include the unglamorous provisions: a UPS sized for a clean shutdown, spare drives on the shelf, and the configuration document kept where a successor administrator will find it.

The specification, in one place

The published figures for the ST550 are the ones carried on this page: form factor: Tower server; type code in the listing: 7X10A0B3NA; listed configurations: Xeon 6240 build and Xeon 3204 build. Those figures are the anchor of the supply offer — they are what the configuration starts from, and every line beyond them (processor alternatives, memory populations, drive models and counts, power and rail options) is settled in writing on the quote rather than assumed from the badge.

Buyers comparing this model should hold the comparison to the same standard: configuration against configuration, line by line. In the Lenovo range this model is quoted alongside its ThinkSystem siblings in the same format, so a two-model comparison on one brief is always available. Ask for serial numbers before shipment, and keep the final written configuration with the asset record — it is the document the machine's whole service life will be checked against.
