time.
Solid-state drives (SSDs), which offer significantly better reliability than mechanical HDDs for
greater uptime.
The power source independent light path diagnostics functionality provides individual LEDs that
lead the technician to failed (or failing) components, which simplifies servicing, speeds up problem
resolution, and helps improve system availability.
The built-in XClarity Controller continuously monitors system parameters, triggers alerts,
and performs recovery actions in case of failures to minimize downtime.
Proactive Platform Alerts (including PFA and SMART alerts): Processors, voltage regulators,
memory, internal storage (SAS/SATA HDDs and SSDs, NVMe SSDs, flash storage adapters), RAID
controllers, and server ambient and sub-component temperatures. Alerts can be surfaced through
the system XClarity Controller to managers such as Lenovo XClarity Administrator, VMware
vCenter, and Microsoft System Center. These proactive alerts let you take appropriate actions in
advance of possible failure, thereby increasing server uptime and application availability.
Built-in diagnostics in UEFI, using Lenovo XClarity Provisioning Manager, speed up
troubleshooting tasks to reduce service time, and supports diagnostic function and to collect
service data to USB key drive or remote CIFS share folder.
Auto-restart in the event of a momentary loss of AC power (based on power policy setting in
the XClarity Controller service processor).
Support for the XClarity Administrator Mobile app running on a supported smartphone
and connected to the server through the service-enabled USB port, enables additional local
systems management functions.
Three-year customer replaceable unit and on-site limited warranty; next business day 9x5. Optional
service upgrades are available.
Manageability and security
The following powerful systems management features simplify the local and remote management of the
SN850:
Support for Lenovo XClarity Administrator, providing auto-discovery, inventory tracking, monitoring,
policy-based firmware updates, address pool management, configuration patterns and operating
system installation.
The server includes an XClarity Controller (XCC) to monitor server availability and perform
remote management. XCC Advanced is supported as standard, which enables remote
KVM, mounting of remote media files (ISO and IMG image files), boot capture, and power capping.
New UEFI-based Lenovo XClarity Provisioning Manager, accessible from F1 during boot,
provides system inventory information, graphical UEFI Setup, platform update function, RAID Setup
wizard, operating system installation function, and diagnostic functions
Integrated Trusted Platform Module (TPM) 2.0 support enables advanced
cryptographic functionality, such as digital signatures and remote attestation.
Supports Secure Boot to ensure only a digitally signed operating system can be used. Supported
with HDDs and SSDs as well as M.2 drives.
Support for Lenovo XClarity Energy Manager which captures real-time power and temperature
data from the server and provides automated controls to lower energy costs.
Industry-standard Advanced Encryption Standard (AES) NI support for faster, stronger encryption.
Intel Execute Disable Bit functionality can help prevent certain classes of malicious buffer overflow
attacks when combined with a supporting operating system.
Intel Trusted Execution Technology provides enhanced security through hardware-based resistance
to malicious software attacks, which allows an application to run in its own isolated space that is
protected from all other software that is running on a system.
