Lenovo ThinkSystem SE450 - 3 year Warranty - CTO only

CTO = configuration to order

ThinkSystem SE450 models can be configured by using the Lenovo Data Center Solution Configurator (DCSC) - https://dcsc.lenovo.com/#/

Configure-to-order (CTO) models are used to create models with factory-integrated server customizations. For CTO models, two base CTO models are available for the SE450 as listed in the following table, CTO1WW and CTOLWW:

The CTO1WW base CTO model is for general business and is selectable by choosing General Purpose mode in DCSC.
The CTOLWW base model is intended for High Performance Computing (HPC) and Artificial Intelligence (AI) configurations and solutions, including configurations for Lenovo Scalable Infrastructure (LeSI), and is enabled using either the HPC & AI LeSI Solutions mode or HPC & AI ThinkSystem Hardware mode in DCSC. CTOLWW configurations can also be built using System x and Cluster Solutions Configurator (x-config).
Preconfigured server models may also be available for the SE450, however these are region-specific; that is, each region may define their own server models, and not all server models are available in every region.
