Leap ahead with Windows Server 2025.

Facing these issues? Lenovo and Microsoft are here to help.

• "We need more performance out of our storage"

  No problem. Lenovo ThinkSystem servers hold 588 world record benchmarks across a wide range of workloads². And Windows Server 2025 ups the game considerably, including up to 60% more IOPs on NVMe SSDs and 31.7% increased CPU saving per IO compared to Windows Server 2022.

  Reduplication and compression on ReFS delivers up to 90% storage savings. File servers provide an additional ~60%. Stretch Clustering provides robust failover solutions and the new Storage Spaces amplifies data efficiency with thin provisioning, deduplication, and tunable repair/resync.

  A truly groundbreaking operating system.

• "We need to power AI efficiently"

  In addition to transformational performance, Windows Server 2025 provides the flexibility and control to maximize efficiency for your most demanding AI workloads – including GPU partitioning across a wide range of NVIDIA GPUs to assign the optimal power to your VMs and different sets of users. Live migration, high availability, and failover clustering minimize disruption and provide added reassurance.

• "We’re spending more to prevent server downtime"

  Aging servers not only cost more to maintain, they are also more prone to downtime. In ITIC research, Lenovo servers are consistently rated #1 for reliability among x86 servers¹.

  Saving you even more time, Windows Server 2025 introduces Azure Arc-enabled* Hotpatching everywhere – allowing you to apply essential updates without rebooting.

  Hotpatching has been available for a few years in Windows Server 2022 Datacenter: Azure Edition, but is now available for both Windows Server 2025 Datacenter and Standard edition.

  What’s more OEM/ROK customers can now connect their servers running Windows Server 2025 to Azure Arc and subscribe to Hotpatching for an additional monthly subscription.

  * Azure Arc-enabled Hotpatch is currently in PREVIEW (as of January 17th 2025).

• "Security is one of our top priorities"

  It’s ours, too. Windows Server 2025 introduces next-generation, foundational security enhancements and modernized authentication with a significantly reduced attack surface to protect both your users and your data.

  Some of the extensive SMB improvements include:

  • Hardened Defaults: Improved encryption, SMB signing by default, and better cryptographic protocols.
  • Brute Force Protection: Mitigates attacks with built-in throttling for SMB.
  • Hotpatching: Reduces downtime by enabling security patching without server reboots (only 4 reboots per year).
  • Active Directory: Advanced encryption, Kerberos enhancements, reduced NTLM reliance, and improved scalability.

  Everything is fully managed with Group Policy or Powershell.

• "We want our upgrade to be as smooth as possible"

  Migrating from previous versions of Windows Server is actually quite straightforward and secure.

  Windows Server 2025 even includes N-4 media upgrade support going back to Windows Server 2012 R2. (Note: Ensure source is fully patched before upgrade. Backup/snapshot is highly encouraged.)

  If needed, Lenovo’s migration services are available to ensure a smooth move to Windows Server 2025.

• "We need to connect our on-premises servers to the cloud"

  With Windows Server 2025, easily connect and manage your on-premises servers and Azure resources in the cloud via Azure Arc, to create a proven hybrid cloud infrastructure. Windows Server 2025 includes an Azure Arc Install Wizard out of the box for simplified enablement with no downloads required.

• "We need quick and easy access to our files remotely"

  Windows Server 2025 includes the game-changing feature, SMB over QUIC.

  QUIC is an IETF-standardized protocol with numerous benefits over the TCP network transport, enabling remote workers and teams to securely and reliably connect to edge and file servers without the need for a VPN.

• "We’ve hit scalability limits"

  Windows Server 2025 supports up to 48 TB of RAM and 64 processor sockets, providing plenty of headroom to meet your future needs.

  Hyper-V enhancements include massive scalability with support for up to 4 PB RAM and 2,048 logical processors per host, as well as up to 240 Terabytes of RAM and 2048 Virtual Processors per VM.

• "We want to modernize with containers"

  Windows Server 2025 provides a modern Windows Container experience with Kubernetes. Startup times and performance are faster than in previous Windows Server versions³.

• "We want to upgrade but our apps don’t support Windows Server 2025 yet"

  Sometimes you aren’t quite ready for the newest operating system. That’s ok. Lenovo’s easy-to-use downgrade kits let you purchase Lenovo with Windows Server 2025 now and operate on a previous version of Windows Server until you’re ready to upgrade.

• "We have sustainability goals to meet"

  With Lenovo Carbon Offset Services, you can offset the carbon emissions for every hardware purchase directly at the time of purchase. You can also significantly reduce energy consumption with the latest Intel® Xeon® and AMD EPYC™ processors in Lenovo servers.

Windows Server 2025 or Azure Local – What’s your way?

Some businesses need new servers to meet needs for higher performance. Some want extended Windows Server or SQL Server support. And 73%⁴ have a hybrid cloud strategy to implement. Whatever your strategy may be, Lenovo has an upgrade path that fits you.
