Leadership enterprise server with significantly lower cost of ownership in a highly available and

Availability and Serviceability 

The System x3650 M3 provides many features to simplify serviceability and increase system 
uptime:  

  x3650 M3 servers offer 

Chipkill 

ECC memory protection

4

 (when using x4 DIMMs). Chipkill 

memory is up to 

16X

 better than standard ECC memory at correcting memory errors. This can 

help reduce downtime caused by memory errors. 

  The x3650 M3 offers 

memory mirroring

 for redundancy in the event of a non-correctable 

memory failure 

 

Toolless

 

cover removal

 provides easy access to upgrades and serviceable parts, such as 

HDDs and memory. Similarly, the Virtual Media Key and the ServeRAID controller can be 
installed and replaced without tools. This means less time (and therefore less money) spent 
servicing the x3650 M3. Additionally, 

hot-swap/redundant HDDs, fan modules

 and 

power 

supplies

, as well as 

online mirrored

 memory, mean greater system uptime while these 

components are being serviced. 

  New 

toolless slides

 ship with the server, together with a 

Cable Management Arm (CMA)

that allow the rack server to easily slide into place 

  IBM 

Thermal Diagnostics

 allows the administrator to evaluate thermal data on the server 

without taking the hardware offline. This can provide greater server uptime. 

  The 

drop-down light path diagnostics panel

 and individual light path LEDs quickly lead the 

technician to failed (or failing) components. This simplifies servicing, speeds up problem 
resolution and helps improve network availability. 

 

Integrated

 

3Gbps

 or 

6Gbps

 RAID controller to enhance system availability and data 

protection without using a PCIe slot. 

 

IPMI 2.0

 supports highly secure remote system power control using data encryption. This 

allows an administrator to restart a server without having to visit it in person, saving travel time 
and getting the server back up and running quickly and securely. It also adds new features to 
those provided by IPMI 1.5, including 

VLAN

 support, 

Serial over LAN

, enhanced 

authentication and encryption algorithms (

RMCP+ 

and

 AES

) and a 

firmware firewall

 

Altitude- and temperature-controlled fans

 adjust to compensate for changing thermal 

characteristics. At the lower speeds they draw less power and suffer less wear. Equally 
important in a crowded data center, temperature-controlled fans produce less ambient noise in 
the data center than if they were constantly running at full speed. 

  The

 three-year (parts and labor) limited onsite warranty

5

 helps afford you peace of mind 

and greater investment protection than a one-year warranty does.
