With the x3850 X6, machine type 6241, Lenovo supports upgrading the server processors by simply by replacing the Compute Books. The process to upgrade is made very simple because of the innovative book design of the x3850 X6.

Supported upgrades are:

• E7 v2 processors to E7 v4 processors (new DDR4 DIMMs required)
• E7 v3 processors with DDR3 to E7 v4 processors (new DDR4 DIMMs required)
• E7 v3 processors with DDR4 to E7 v4 processors (optionally keep existing memory)

Notes:

• E7 v3 processors are now withdrawn, so you cannot upgrade to E7 v3 processors.
• Upgrades to v4 processors are only supported with machine type 6241. If you want to upgrade an X6 server with machine type 3837, contact your local representative.
• eXFlash DIMMs (now withdrawn) are not supported with TruDDR4 memory; Only DDR3 memory is supported
• Intel Xeon E7 v4 processors require minimum firmware levels. Consult the documentation that is included with the Compute Books.
• Compute books with E7 v4 processors do not support DDR3 memory
• If you upgrade from E7 v3 processors with DDR4 to E7 v4 processors, you can transfer the 2133 MHz DDR4 memory DIMMs to the new compute books. If you also want to add additional memory to the E7 v4 compute book, it is supported to use either 2133 MHz or 2400 MHz DDR4 memory DIMMs. It is supported to mix 2133 MHz and 2400 MHz DIMMs in the same compute book.

The x3850 X6 server has a flexible modular design that allows you to increase the server’s compute power and I/O capabilities by adding additional Compute Books and I/O Books. The modular design also means that if your business needs additional processing or I/O capability within the same system image, then it is possible to migrate to an eight-socket x3950 X6.

Lenovo supports upgrading a 4-socket X6 server to an 8-socket X6 server. The two recommended methods are as follows:

• Start with a 4-socket x3950 X6 (8U chassis) and add additional processors when needed
• Start with a 4-socket x3850 X6 (4U chassis) and upgrade it when needed using an option part number

Option 1: Start with a 4-socket x3950 X6

With this option, you plan for the need for future 8-socket performance in advance and purchase an x3950 X6 with only four Compute Books installed. The initial order would contain:

• Four Compute Books with E7-8800 v3 or v4 series processors (not E7-4800 processors)
• Four Power Supplies (preferably 1400W)
• Two Primary IO Book standard
• Two Storage Book Standard

Once the need arises to upgrade the server to six or eight processors, simply purchase more Compute Books with the same processor model, plus additional power supplies (as determined by using the Power Configurator), I/O Books, adapters and drives as needed.

For information about the x3950 X6, see the Lenovo System x3950 X6 Product Guide:
http://lenovopress.com/tips1251

Note: It is supported to install E7-4800-based Compute Books in a x3950 X6 from either an System x3850 X6 (machine type 3837) or a Lenovo System x3850 X6 (machine type 6241)

The part number includes the following major components:

• 1x 8U chassis and 8-socket midplane
• 1x Primary I/O Book
• 1x Storage Book

Engage a Lenovo service engineer to come onsite to perform the field upgrade by transferring all components to the new chassis. This method also requires the x3850 X6 compute books be the same E7-8800 series processors as ordered, however, in this scenario, the server maintain the original serial number.

Note: Use of E7-4800 processors: Intel Xeon E7-4800 v2/v3/v4 processors cannot be used in an x3950 X6. If your x3850 X6 has Compute Books with E7-4800 processors, then these must be replaced with Compute Books with E7-8800 processors if you plan to upgrade to an x3950 X6. The memory in the Compute Books can be reused in the x3950 X6, however (provided the selected processors support the memory type, DDR3 or DDR4).

The major parts of the 4U to 8U upgrade are the 8U chassis, the Storage Book and the Primary I/O Book. All the components in the package will be installed in the top portion of the chassis. The 4U system's components will be transferred to the bottom section of the chassis.

Even though this upgrade requires a new 8U chassis replacing the existing 4U chassis, the majority of internal components can be moved from the x3850 X6 to the x3950 X6.

The x3850 X6 components that can be migrated to the x3950 X6 as part of the upgrade are:

• Compute Books, provided they use Intel Xeon E7-8800 processors
• All memory DIMMs
• Storage Book
• All internal drives
• Primary I/O Book (and associated fans)
• Half-length I/O Books
• Full-length I/O Books
• All adapters
• All power supplies

The upgrade may also require new parts:

• Additional Compute Books (a minimum of four Compute Books required in the x3950 X6)
• Additional power supplies (a minimum of four are required in the x3950 X6)
• Additional I/O Books, network adapters, drives as needed

There are key considerations for this upgrade:

• Processor support: Intel Xeon E7-4800 v2/v3/v4 processors cannot be used in an x3950 X6. If your x3850 X6 has Compute Books with E7-4800 processors, then these must be replaced with Compute Books with E7-8800 processors if you plan to upgrade to an x3950 X6. The memory in the Compute Books can be reused in the x3950 X6, however.
• All processors must be identical: All processors used in the x3950 X6 must be the identical. For example, all E7-8850 v3 processors. A minimum of four processors are required.
• The upgrade does result in some parts no longer being used (“parts on the floor”):
• Existing 4U chassis and 4-socket midplane
• Compute Books that are based on E7-4800 processors
• Original x3850 X6 server may need to be ordered configure-to-order (CTO) or Special Bid: To minimize “parts on the floor” (parts that cannot be used in the upgraded system), the original x3850 X6 should be configured with Compute Books containing E7-8800 processors. Since many standard models of the x3850 X6 (see Table 2) contain E7-4800 processors, you may need to use configure-to-order or order the server using Special Bid to create a server configuration with E7-8800 processors.
• Serial number swap: The upgrade process also involves transferring the x3850 X6 serial number to the x3950 X6 chassis. This transfer makes the upgrade simpler from an asset or depreciation management point of view. This transfer also means that the old 4U chassis will be retired as it will no longer have a valid serial number.
• Power supplies: Ideally all power supplies are the 1400W variant. Regardless of the selection, the power supplies coexistence rules as described in the Power supplies section must be followed.
• Additional power: Depending on your workload and configuration you may need to provision for additional PDU outlets, cables and power capacity for your x3950 X6 server. Use the Lenovo Power Configurator to determine your total power draw to assist you in provisioning adequate power. You can download the Power Configurator from https://support.lenovo.com/documents/LNVO-PWRCONF
• Additional rack space: An additional 4U of rack space is required when upgrading the x3850 X6 to the x3950 X6, for a total of 8U of rack space.
• Down time: In order to upgrade the x3850 X6 server to an x3950 X6 server you will need to allow for down time. The server will need to be completely powered off and have some of its components removed for re-installation into the new x3950 X6 server.

The x3850 X6 supports up to four Intel Xeon E7 v4 processors. Compute books with E7 v3 or E7 v2 processors are now withdrawn from marketing. Processors are installed in Compute Books, one processor in each Compute Book. The following figure shows the components of the Compute Book:

• One processor
• A total of 24 DIMM slots, 12 on each side of the book
• Two hot-swap dual-motor fans that are mounted on the front of the book

The x3850 X6 supports two or four Compute Books. Three Compute Books are not supported. A configuration of one Compute Book is only supported in standard models 6241-A4x and 6241-D5x.

Each Compute Book is installed in the front of the server, as shown in the following figure.

Figure 4. Compute Book

Each option includes the processor installed in a Compute Book. Compute Books with one of the E7-4800 family of processors are supported only in a four-socket x3850 X6 server and cannot be used in an x3950 X6 server. All Compute Books installed in a server must be identical.

The table also shows the maximum memory bus speed each processor supports plus which server models have each processor standard. If there is no corresponding where-used model for a particular processor, this processor is only available through CTO.

‡ The first feature code is for the first Compute Book. The second feature code is for all additional Compute Books
† The processors support two memory modes, RAS mode (also known as lockstep mode) and Performance mode (also known as independent mode). In Performance mode, the SMI2 link operates at twice the memory bus speed shown.

The x3850 X6 (6241) supports either DDR3 or TruDDR4 memory, depending on the Compute Books used in the server.

Lenovo TruDDR4 Memory uses the highest quality components that are sourced from Tier 1 DRAM suppliers and only memory that meets the strict requirements of Lenovo is selected. It is compatibility tested and tuned to maximize performance and reliability. TruDDR4 Memory has a unique signature that is programmed into the DIMM that enables System x® servers to verify whether the memory that is installed is qualified or supported by Lenovo. Because TruDDR4 Memory is authenticated, certain extended memory performance features can be enabled to extend performance over industry standards.

Lenovo DDR3 memory is compatibility tested and tuned for optimal System x performance and throughput. Lenovo memory specifications are integrated into the light path diagnostics for immediate system performance feedback and optimum system uptime.

From a service and support standpoint, Lenovo TruDDR4 and DDR3 memory automatically assumes the system warranty, and Lenovo provides service and support worldwide.

The x3850 X6 supports TruDDR4 memory operating at speeds up to 1866 MHz and DDR3 memory at speeds up to 1600 MHz. Note that even though supported TruDDR4 DIMMs are rated at 2400 MHz or 2133 MHz, when used in the x3850 X6, they operate at speeds up to 1866 MHz.

The x3850 X6 supports up to 96 DIMMs when all processors are installed, 24 DIMMs per processor. Each processor has four memory channels that are implemented using Scalable Memory Interface generation 2 (SMI2) chips, and the server implements three DIMMs per channel. The processor and the corresponding memory DIMM slots are on the Compute Book.

The following table lists the memory options that are available for x3850 X6.

The following rules apply when selecting the memory configuration:

• The server supports RDIMMs and LRDIMMs.
• DDR4 Compute Books support mixing 2133 MHz and 2400 MHz DDR4 memory. (Note: 2133 MHz DIMMs are now withdrawn)
• Mixing different types of memory (combinations of RDIMMs, LRDIMMs, and 3DS RDIMMs) is not supported.
• Mixing different generations of memory (DDR3 and TruDDR4) is not supported
• The maximum number of ranks per one memory channel is six with RDIMMs, 12 with LRDIMMs, or 24 with 3DS RDIMMs.
• In RAS (lockstep) mode, DIMMs must be installed in a pair.
• The maximum quantity of DIMMs that can be installed in the server depends on the number of processors, DIMM type, rank, and operating voltage, as shown in the "Maximum qty supported" row in the following table.
• All DIMMs in the server operate at the same speed, which is determined as the lowest value of one of the following options:
  • Memory speed that is supported by the specific processor.
  • Lowest of maximum operating speeds for selected memory configuration that depends on rated speed, operating voltage, and quantity of DIMMs per channel, as shown under "Maximum operating speed" section in the following table.

The following table shows the characteristics of the supported DIMMs. Table cells that are highlighted with a gray background indicate that the server supports higher memory frequencies or larger memory capacity (or both) than the Intel processor specification defines.

Memory speed: In performance mode, memory channels operate independently, and the SMI2 link operates at twice the DDR3 speed. In RAS mode, two channels operate synchronously, and the SMI2 link operates at the DDR3 speed.

* Maximum quantity supported is shown for all processors that are installed
† This speed is above the Intel standard and is achieved only when Lenovo TruDDR4 memory is used

The following memory protection technologies are supported:

• ECC
• Chipkill (for x4-based memory DIMMs)
• Redundant bit steering (Double Device Data Correction)
• Memory mirroring
• Memory rank sparing

Chipkill and Redundant Bit Steering are supported in RAS mode. Chipkill is supported in Performance mode.

If memory mirroring is used, DIMMs must be installed in pairs for Performance mode (minimum of one pair per each processor) and quads for RAS mode. DIMMs in the pair/quad must be identical in type and size.

If memory rank sparing is used, then a minimum of two single-rank or dual-rank DIMMs must be installed per populated channel (the DIMMs do not need being identical). In rank sparing mode, one rank of a DIMM in each populated channel is reserved as spare memory. The size of a rank varies depending on the DIMMs that are installed.

The x3850 X6 server supports 1.8-inch solid-state drives and 2.5-inch SSDs and HDDs. Drives are installed in the Storage Book. The x3850 X6 has one Storage Book. The Storage Book supports the following configurations:

• 4x 2.5-inch hot-swap drive bays
• 8x 2.5-inch hot-swap drive bays
• 4x 2.5-inch hot-swap drive bays + 8x 1.8-inch hot-swap SSD bays
• 8x 1.8-inch hot-swap SSD bays
• 16x 1.8-inch hot-swap SSD bays
• 4x 2.5-inch PCIe NVMe SSDs
• 2x 2.5-inch PCIe NVMe SSDs + 8x 1.8-inch HDD hot-swap drives

* Withdrawn from marketing

The backplanes are connected to one or two RAID controllers or HBAs depending on the number and type of backplane that is installed. The adapters are installed in PCIe slots in the Storage Book, as shown in the following figure.

Figure 6. Storage Book

The following table shows the backplanes that are required per Storage Book and the number of controllers that are required. Note that the table shows the exact number of controllers supported for each drive/backplane configuration, no more, no fewer.

Table 9. Drive combinations per Storage Book

* The number of controllers required is dependent on the number of drives installed: 1 or 2 drives requires one controller, and 3 or 4 drives requires two controllers.

The following table lists the RAID controllers, HBAs, and additional hardware and feature upgrades that are used for internal disk storage. The adapters are installed in slots in the Storage Book.

* These M5210 features upgrades require a cache memory upgrade (47C8656, 47C8660, or 47C8664).

The following table compares the features of the supported controllers.

For more information, see the list of Lenovo Press Product Guides in the RAID adapters category:
https://lenovopress.com/servers/options/raid

The NVMe PCIe SSD Extender Adapter is a PCIe adapter that simply routes the PCIe 3.0 x8 signal from the slot in the Storage Book, splits the signal to two x4 links, and routes those via cables to the drive backplane. The extender adapter is shown in the following figure.

One adapter is required for every two drives installed in the Storage Book. Since there are only two PCIe slots in the Compute Book, only two adapters can be installed and therefore only four NVMe drives can be installed in a Storage Book.

* The Full-length I/O Book can be ordered only as an option. It is not available through CTO because the Full-length I/O Book cannot be shipped installed in the server

The following figure shows the two optional I/O Books, the Half-length I/O Book and the Full-length I/O Book.

Figure 9. Half-length I/O Book and the Full-length I/O Book

The following figure shows the inside of the Half-length I/O Book.

Figure 10. Half-length I/O Book

Each slot in the Half-length I/O Book and the Full-length I/O Book supplies up to 75 W of power.

The Full-length I/O Book also includes two auxiliary power connectors. With the use of these connectors and the supplied power cords, the I/O book supports one double-wide adapter up to 300 W. The auxiliary power connectors are as follows:

• One 2x4 power connector, which supplies up to 150 W of additional power to the adapter
• One 2x3 power connector, which supplies up to 75 W of additional power to the adapter

The combined power consumption of all the adapters that are installed in the Full-length I/O Book cannot exceed 300 W.

Note: The 2x3 connector is intended to be used only when one adapter is installed in the first x16 slot (the up-most slot in the following figure), either requiring 225 W or 300 W of power. The location of the 2x3 connector prevents an adapter from being installed in the other x16 slot.

Figure 11. Full-length I/O Book

The Half-length I/O Book installs flush with the Primary I/O Book at the rear of the server. The Full-length I/O Book, when installed, adds a 99 mm (3.9 in.) mechanical extension to the base length dimension of the chassis.

The x3850 X6 server supports up to four redundant power supplies. Standard models come with one, two, or four power supplies (model dependent). The following table lists the power supplies.

Table 25. Power supplies

An AC power supply ships standard with one 2.8 m C13 - C14 power cord.

Configuration rules are as follows:

• Power supplies must be in pairs (x3850 X6) or quads (x3950 X6), with the exception of model 3837-A4x, where one power supply is supported.
• The AC power supplies can be mixed. Valid combinations for the x3850 X6 for example, are:
  • Two 44X4132 and two 44X4152
  • Two 44X4132 and two 44X4150
• It is not recommended you mix the two 1400 W options (44X4152 for low altitude and 44X4150 for high altitude) as you will nullify the high-altitude capabilities of 44X4150.
• You cannot mix the AC power supplies with the DC power supply
• Use the Power Configurator to determine exactly what power your server needs:

The server supports VMware ESXi that is installed on a USB memory key. The key is installed in a USB socket that is on the primary I/O book inside the server. The following table lists the virtualization options.

* Not supported in servers with E7 v2 compute books  

The server contains Integrated Management Module II (IMM2), which provides advanced service-processor control, monitoring, and an alerting function. If an environmental condition exceeds a threshold or if a system component fails, the IMM2 lights LEDs to help you diagnose the problem, records the error in the event log, and alerts you to the problem. The IMM2 also provides a virtual presence capability for remote server management capabilities.

The IMM2 provides remote server management through industry-standard interfaces:

• Intelligent Platform Management Interface (IPMI) Version 2.0
• Simple Network Management Protocol (SNMP) Version 3
• Common Information Model (CIM)
• Web browser

The remote presence provides the following functions:

• Remotely viewing video with graphics resolutions up to 1600 x 1200 at 75 Hz with up to 23 bits per pixel colors, regardless of the system state
• Remotely accessing the server by using the keyboard and mouse from a remote client
• Mapping the CD or DVD drive, diskette drive, and USB flash drive on a remote client, and mapping ISO and diskette image files as virtual drives that are available for use by the server
• Uploading a diskette image to the IMM memory and mapping it to the server as a virtual drive

The blue-screen capture feature captures the video display contents before the IMM restarts the server when the IMM detects an operating-system hang condition. A system administrator can use the blue-screen capture feature to assist in determining the cause of the hang condition.

Because Lenovo XClarity Administrator does not require any agent software to be installed on the managed endpoints, there are no CPU cycles spent on agent execution, and no memory is used, which means that up to 1GB of RAM and 1 - 2% CPU usage is saved, compared to a typical managed system where an agent is required.

Lenovo XClarity Administrator is an optional software component for the x3850 X6. The software can be downloaded and used at no charge to discover and monitor the x3850 X6 and to manage firmware upgrades.

If software support is required for Lenovo XClarity Administrator, or premium features such as configuration management and operating system deployment are required, Lenovo XClarity Pro software subscription should be ordered. Lenovo XClarity Pro is licensed on a per managed system basis, that is, each managed Lenovo system requires a license.

The following table lists the Lenovo XClarity software license options.

For more information, refer to the Lenovo XClarity Administrator Product Guide:

  Our in-depth knowledge of the products, services and various market segments allows us to offer greater flexibility in structures, documentation and end of lease options.

• 100% Solution Financing

  Financing your entire solution including hardware, software, and services, ensures more predictability in your project planning with fixed, manageable payments and low monthly payments.

• Device as a Service (DaaS)

  Leverage latest technology to advance your business. Customized solutions aligned to your needs. Flexibility to add equipment to support growth. Protect your technology with Lenovo's Premier Support service.

• 24/7 Asset management

  Manage your financed solutions with electronic access to your lease documents, payment histories, invoices and asset information.

• Fair Market Value (FMV) and $1 Purchase Option Leases

  Maximize your purchasing power with our lowest cost option. An FMV lease offers lower monthly payments than loans or lease-to-own financing. Think of an FMV lease as a rental. You have the flexibility at the end of the lease term to return the equipment, continue leasing it, or purchase it for the fair market value. In a $1 Out Purchase Option lease, you own the equipment. It is a good option when you are confident you will use the equipment for an extended period beyond the finance term. Both lease types have merits depending on your needs. We can help you determine which option will best meet your technological and budgetary goals.
