The orchestration platform for conducting business
Infrastructure Made Simple
The Lenovo Flex System Enterprise Chassis now supports two new blades, incorporating powerful Intel® Xeon® processor Scalable family CPUs: the four-processor Lenovo ThinkSystem SN850 and the two-processor Lenovo ThinkSystem SN550.
The chassis was engineered to support high-speed networking and multiple generations of Intel Xeon processors.
SN850 offers massively increased memory capacity and bandwidth, more processor cores, faster and larger storage capacity, plus enhanced RAS and security features**. As a result, SN850’s four-CPU, 48 DIMM-slot design is powerful enough for even your most demanding memory-intensive workloads.
Examples include in-memory databases, batch and real-time analytics, virtualization, large traditional databases, distributed computing, or consolidating multiple past generation servers onto a single blade.
In addition, SN850 is also compatible with your current Flex System Enterprise chassis, protecting your investment in chassis infrastructure.
Elastic Infrastructure for Ever-Changing Workloads
Making your infrastructure more easily composable is what Flex System is all about. Teamed with the Lenovo XClarity management suite, you can compose compute, storage, and networking resources to adapt to changing workload and capacity requirements.
This extreme agility gives customers new levels of command over their resources:
- Faster virtual machine deployment and movement for easier orchestration
- Storage flexibility, from no drives to a choice of SAS/SATA HDDs/SSDs or NVMe/U.2
- NVMe drives, for ultra-fast read/write storage that can be tiered for greater application performance
- Direct-Connect NVMe ports—Four direct motherboard connections for NVMe storage provide ultra-fast read/writes and reduce costs by eliminating PCIe switch adapters. Plus, storage can be tiered for faster application performance to deliver the most cost-effective solution.
- Choice of multiple boot devices, including M.2
These are a few of the incorporated technologies and features that deliver an extremely agile blade architecture, and provide the infrastructure control to free your staff time to focus on innovation and new challenges.
Efficient On Multiple Levels
The Flex System Enterprise Chassis houses up to 7 ThinkSystem SN850 blades and 4 integrated switches, delivering up to 80 percent greater density than 2U 4-processor rack servers and 1U switches*—with the added bonus of reducing the number of cables (and cabling complexity) by nearly half.
The chassis design creates efficiency via:
- Simplified, flexible, and fast deployment and management with Lenovo XClarity Administrator software, for future-defined data centers
- Up to four integrated networking switches for improved throughput and reduced cable count
- Zoned adaptive cooling, which varies system fan speeds as needed, to reduce energy costs
- Energy-efficient components, including 80 Plus Platinum hot-swap/redundant power supplies
Flex System helps save time and money by greatly reducing your costs for energy and floor/rack-space, and by simplifying management. Reduced complexity enables your infrastructure to become a powerful tool—ready for the future—instead of a drain on resources.
A Proven Platform
Flex System is a second-generation blade system that has helped customers streamline their infrastructure since 2012. The ability to run four generations of Intel® Xeon® processor-based blades concurrently in the same chassis, makes Flex System ready for the “future-defined data center”.
The Flex System Enterprise Chassis houses up to 7 SN850 compute nodes, delivering high density.
Redundancy is prevalent throughout, including switches, management modules, blades, power supplies, and cooling systems. There is no single point of failure in Flex System. It also features:
- Enterprise-class CPU RAS—such as MCA Recovery, Memory Post Package Repair, and Fatal Error Handling—to keep systems running.
- Cable-free blades, which accelerate servicing and reduce upgrade times
- The XClarity mobile app, which allows remote diagnostics and management from a credentialed mobile device or smart phone
- Worldwide Lenovo service and support, available in more than 140 countries
ThinkSystem Server Deployment and Management
Lenovo XClarity Controller is an all-new hardware embedded management engine common in every ThinkSystem server. XClarity Controller features an uncluttered graphical user interface, industry standard Redfish-compliant REST APIs, and enables booting in half the time of the prior generation servers**, with up to 600 percent faster firmware updates.
Lenovo XClarity Administrator is a virtualized application that centrally manages ThinkSystem servers, storage, and networking. Via reusable patterns and policies, it ramps up and scales infrastructure provisioning and maintenance. It serves as a central integration point to extend your data center management processes to physical IT. Running XClarity Integrators in external IT applications, or integrating through REST APIs, helps you further speed services provisioning, streamline IT management, and contain costs.
