Node Naming (NX-3155G-G7)
Nutanix assigns a name to each node in a block, which varies by product type.
The NX-3155G-G7 block contains a single node named Node A.

Note: Power consumption is higher when GPU cards are present.

CAUTION: Do not use the NVIDIA Tesla M10 GPU card on hypervisors running more than 1TB of
total memory, due to NVIDIA M-series architectural limitations. The T4 and V100 GPU cards are
not subject to this limitation.

Node Naming (NX-8155-G7)

Nutanix assigns a name to each node in a block, which varies by product type.
The NX-8155-G7 requires a minimum of Foundation 4.4.2. Update all nodes in the cluster to
Foundation 4.4.2 or later.
The NX-8155-G7 block contains a single node named Node A.
The NX-8155-G7 has twelve drive slots. The first two SSDs contain the Controller VM and
metadata. All HDDs (if used) are data-only drives.

Figure 14: NX-8155-G7 front panel (NVMe configuration shown)

Platform | System Specifications | 25

Partial Population
The NX-8155-G7 supports partially populating the chassis with fewer than the maximum
number of drives, according to the following restrictions:

• Partially populated configurations support only even numbers of drives.

• SSD with NVMe configurations must include a minimum of four SSDs.
• Populate the drive slots in order from bottom to top and left to right.
When partially populating a node, Nutanix recommends that you put an empty drive carrier in
each unpopulated drive slot, for air flow and to prevent dust contamination.

Drive Configurations

Note: If you order a hybrid SSD and HDD configuration, you can later convert the platform to
an all-SSD configuration. However, if you begin with either a hybrid SSD and HDD or an all-SSD
configuration, you cannot later convert to an SSD with NVMe configuration.

Certain capacities of HDDs can only mix with certain capacities of SSDs.

Power Supply Unit (PSU) Redundancy and Node Configuration (G7

Platforms)
Note: Nutanix recommends that you carefully plan your AC power source needs, especially in
cases where the cluster consists of mixed models.
Nutanix recommends that you use 180~240V AC power source to secure PSU
redundancy. However, according to the table below and depending on the number of
nodes in the chassis, some NX Series platforms can work with redundant 100~210V AC
power supply units.

Block Connection in a Customer Environment

After physically installing the Nutanix block in the datacenter, you can connect the network
ports to the customer's network.

• A switch that can auto-negotiate to 1Gbps is required for the IPMI ports on all G6 platforms.
• A 10 GbE switch that accepts SFP+ copper cables is required for most blocks.
• Nutanix recommends 10GbE connectivity for all nodes.
• The 10GbE NIC ports used on Nutanix nodes are passive. The maximum supported Twinax
cable length is 5 meters, per SFP+ specifications. For longer runs fiber cabling is required.

Platform | Component Specifications | 42

 • Nutanix offers an SFP-10G-SR adapter to convert from SFP+ Twinax to optical. This allows a
switch with a 10GbE optical port to maintain the 10GbE link speed on an optical cable.
• Nutanix does not recommend the use of Fabric Extenders (FEX) or similar technologies
for production use cases. While initial, low-load implementations might run smoothly
with such technologies, poor performance, VM lockups, and other issues might occur as
implementations scale upward (see Knowledge Base article KB1612). Nutanix recommends
the use of 10Gbps, line-rate, non-blocking switches with larger buffers for production
workloads.

Tip: If you are configuring a cluster with multiple blocks, perform the following procedure on all
blocks before moving on to cluster configuration.

Connecting the Nutanix Block

Before you begin

This procedure requires the following components:

• One Nutanix block (installed in a rack but not yet connected to a power source)
• Customer networking hardware, including 10 GbE ports (SFP+ copper) and 1 GbE ports
• One 10 GbE SFP+ cable for each node (provided).
• One to three RJ45 cables for each node (customer provided)
• Two power cables (provided)

CAUTION: Note the orientation of the ports on the Nutanix block when you are cabling the ports.

Procedure

1. Connect the 10/100 or 10/100/1000 IPMI port of each node onto the customer switch with
RJ45 cables.
The switch that the IPMI ports connect to must be capable of auto-negotiation to 1Gbps.

2. Connect one or more 10 GbE ports of each node to the customer switch with the SFP+
cables. If you are using 10GBase-T, optimal resiliency and performance require CAT 6 cables.

3. (Optional) Connect one or more 1 GbE or 10 GBaseT ports of each node to the customer
switch with RJ45 cables. (For optimal 10GBaseT resiliency and performance use Cat 6
cables).

4. Connect both power supplies to a grounded, 208V power source (208V to 240V).

Tip: If you are configuring the block in a temporary location before installing it on a rack, the
input can be 120V. After moving the block into the datacenter, make sure that the block is
connected to a 208V to 240V power source, which is required for power supply redundancy.

5. Confirm that the link indicator light next to each IPMI port is illuminated.

Platform | Component Specifications | 43

6. Turn on all nodes by pressing the power button on the front of each node (the top button).
The top power LED illuminates and the fans are noticeably louder for approximately 2
minutes.

MEMORY CONFIGURATIONS
Supported Memory Configurations (G7 Platforms)
This topic shows DIMM installation order for all Nutanix G7 platforms. Use the rules and
guidelines in this topic to remove, replace, or add memory.

DIMM Restrictions
Each G7 node must contain only DIMMs of the same type, speed, and capacity.
DIMMs from different manufacturers can be mixed in the same node, but not in the same
channel:

• DIMM slots are arranged on the motherboard in groups called channels. On G7 platforms, all
channels contain two DIMM slots (one blue and one black). Within a channel, all DIMMs must
be from the same manufacturer.
• When replacing a failed DIMM, ensure that you are replacing the old DIMM like-for-like.
• When adding new DIMMs to a node, if the new DIMMs and the original DIMMs are from
different manufacturers, arrange the DIMMs so that the original DIMMs and the new DIMMs
are not mixed in the same channel.

• EXAMPLE: You have an NX-3060-G7 node that has twelve 32GB DIMMs for a total of
384GB. You decide to upgrade to twenty-four 32GB DIMMs for a total of 768GB. When
you remove the node from the chassis and look at the motherboard, you will see that
each CPU has six DIMMs, filling all blue DIMM slots, with all black DIMM slots empty.
Remove all DIMMs from one CPU and place them in the empty DIMM slots for the other
CPU. Then place all the new DIMMs in the DIMM slots for the first CPU, filling all slots. This
way you can ensure that the original DIMMs and the new DIMMs do not share channels.

Note: You do not need to balance numbers of DIMMs from different manufacturers within a
node, so long as they are never mixed in the same channel.

Memory Installation Order for G7 Platforms

A memory channel is a group of DIMM slots.
For G7 platforms, each CPU is associated with six memory channels. Each memory channel
contains two DIMM slots. Memory channels have one blue slot and one black slot each.

Platform | Memory Configurations | 45

Figure 24: DIMM slots for a G7 multi-node motherboard

Figure 25: DIMM slots for a G7 single-node motherboard

Note: DIMM slots on the motherboard are most commonly labeled as A1, A2, and so on. However,
some software tools report DIMM slot labels in a different format, such as 1A, 2A, or CPU1, CPU2,
or DIMM1, DIMM2.
