A Principled Technologies reference architecture 4Dell XC630-10 Nutanix on VMware ESXi reference architecture
EXECUTIVE SUMMARY
Introduction
Datacenters have traditionally separated compute and storage resources. While
this made sense for some, it also posed challenges in the areas of performance,
scalability, and cost. A more modern approach brings these resources together into
hyperconverged solutions, in which compute and storage share a chassis.
The Dell XC630-10 system powered by Intel processors E5-2630 v3 and using
Nutanix® software is one such hyperconverged solution. Its unique architecture
combines 1U form factor Dell XC630-10 appliances, Intel processors, onboard storage,
and Nutanix cluster software in a flexible and scalable package that uses minimal
datacenter space, which has the potential to lower power and cooling costs.
In the Principled Technologies datacenter, we set up the Dell and Intel
hyperconverged solution on a VMware® vSphere® (ESXi™) 6.0 cluster. To see how well
the solution functioned, we tested a mixed workload, including Microsoft® Exchange
Server, Microsoft SQL Server®, file and print activity, and disk activity simulating a web
server—a workload that reflects what a small to medium-sized company might do on a
daily basis.
In this reference architecture, we present our findings and offer a guide and
best practices for implementing this solution in your datacenter.
Objective
This reference architecture shows how the Dell XC630-10 system powered by
the Intel Xeon processor E5-2630 v3 and using Nutanix software functioned well with
mixed workloads when configured as a VMware vSphere cluster. It also provides best
practices and a configuration guide for setting up this Dell and Intel solution running
VMware vSphere in the datacenter of a medium-sized business.
Audience
We have targeted this reference architecture to an audience of IT
administrators at small to medium businesses with several hundred employees. Note
that we do not describe every possible configuration of each component in the Dell and
Intel solution.

SOLUTION DESIGN AND CONFIGURATION
Overview of the scope of this guide
In this guide, we walk through the various aspects of setting up a
working Nutanix cluster on a three-node Dell XC630 appliance configuration. We
cover the network setup, including cabling, switch configurations, and VLAN
tagging; initial cluster creation for Nutanix and vSphere, and cluster storage
configuration for a three-node cluster of Dell XC630-10 appliances. We will also
highlight best practices as appropriate.
Before you begin
In preparation for setting up your Nutanix environment on VMware
with XC630 hosts, you will need one IP address available for the cluster’s IP
address and at least three IP addresses per host: one each for the host’s CVM,
the host’s management, and the host’s IPMI interface. In our environment, we
used VLAN tagging to keep the IPMI network separate from the CVM traffic, but
a flat network could also be set up to avoid our more complex network design.
The IPMI interfaces are required for successful cluster deployment, even though
their reachability does not affect the normal functioning of the Nutanix cluster
post-install. Also, note that if your IPMI interfaces are not configured with
routable IP addresses, some support and management functionality could
potentially be impacted.
Assumptions of this guide
We assume in this guide that each Dell XC630 appliance has had ESXi 6.0
pre-installed and the Nutanix Phoenix flashing process performed already
(Phoenix takes care of configuring disks, networking, and Nutanix Controller VM
creation). We also assume the administrator following this guide has an existing
vCenter server or appliance, DNS server, and gateway in his or her environment.
We assume that before beginning the methodology steps, you have configured
the iDRAC/IPMI interface on each host with an IP address and subnet mask, and
provided them with the existing DNS and gateway addresses.
From a networking perspective, we designed this guide to be
representative of a real-world enterprise environment, rather than a basic flat
network. Though we cover setup for a more complex network infrastructure,
including redundant switches, VLAN tagging to segregate traffic, and virtual link
trunking, Nutanix can be deployed on a vSphere environment in a similar
fashion on a simpler network.

Introduction to Nutanix architecture
Nutanix uses a hyperconverged infrastructure to provide a tiered
storage solution to VMs. Every host in a Nutanix cluster houses a Controller VM
(CVM), which runs the Nutanix software and handles all storage I/O operations
for the host’s hypervisor and all the VMs residing on that host. In the case of
ESXi, the host server’s SSDs and hard disk drives are directly passed through to
the CVM for management.
Administrators can create a storage container from the Nutanix cluster’s
disks to be used as storage for all the cluster’s hosted VMs. Nutanix cluster
nodes typically have a small number of fast but low-capacity SSDs and a larger
number of slower but high-capacity HDDs. Nutanix’s storage
tiering/prioritization works to move data to the most appropriate location
(either local SSDs, cluster SSDs, or HDDs) based on availability of fast storage
and how frequently the data in question is accessed. By converging compute
and storage resources into single appliance nodes, scaling Nutanix clusters out is
easy and flexible.
Solution architecture and diagrams
Every Dell XC630 appliance in a Nutanix cluster has the same basic
configuration: a tier of SSD-based flash storage, a tier of hard disk drives,
compute resources in the form of two Intel Xeon processors E5-2630 v3, and
192 GB of DDR4 RAM. At the hypervisor layer, each host runs VMware ESXi,
which hosts a single Nutanix Controller VM, and as many other VMs as you
configure for your environment (see Figure 1).

Figure 1: The structure of each node in our Nutanix cluster.
Once the cluster has been created, the flash and hard disk storage resources
from each node are logically grouped and defined through software as a storage pool.
From there, a container is created and used for housing the virtual hard disks and virtual
machine configuration files for your environment. Although we did not use these
features, Nutanix offers storage efficiency technologies such as deduplication, which
removes duplicate data to increase the effective amount of storage resources available
and accelerate performance, as well as thin provisioning, which allows a LUN to be
created without allocating physical storage space that would go unused initially (more
physical space is used as the actual space fills up). For more information on
deduplication as provided by Nutanix, go to
www.nutanix.com/products/features/enterprise-storage/deduplication/. Figure 2
shows how the storage for the three-node cluster we tested was configured.

Figure 2: The Nutanix storage cluster’s container is comprised of the flash and hard disk
storage from each host.
Our environment used redundant 10 Gbps Dell Networking S4048-ON switches
for cluster/VM traffic and vMotion, and redundant 1 Gbps Dell Networking N2024
switches for IPMI traffic. We used VLAN tagging to segregate the public traffic from the
vMotion traffic and Fault Tolerance traffic, Dell Virtual Link Trunking (VLT) between the
S4048-ON switches, and 1 Gbps links between the S4048-ON switches and the N2024
switches (see Figure 3).
Figure 3: The network configuration for the Nutanix cluster we tested on Dell XC630 appliances.

The Dell XC630 is configured (by the Phoenix flashing process) with a NIC team
created from the two 10Gb SFP ports on the Intel X520/i350 network daughter card.
Two virtual switches come preconfigured as well: one for traffic between the host and
the Nutanix CVM, and one for Nutanix cluster, vSphere management, and VM traffic.
We will later create VMkernel ports on the management switch for vMotion traffic and
Fault Tolerance traffic (see Figure 4).
Figure 4: The structure of each XC630 host’s NIC team, formed from the two 10 Gbps ports, and
their virtual switches and VMkernel ports and port groups. Note that the 1 Gbps ports are
unused.
Creating the Nutanix cluster
1. Perform the following on each of the Controller VMs to configure their IP addresses:
a. Log in with the default admin credentials.
b. Using vi, edit /etc/sysconfig/network-scripts/ifcfg-eth0, setting
BOOTPROTO=static, IPADDR=XX.XX.XX.XX,
NETMASK=YY.YY.YY.YY, and GATEWAY=ZZ.ZZ.ZZ.ZZ, using
appropriate values for the IP address, subnet mask, and gateway.
Save and close the file.
c. Using vi, edit /etc/resolv.conf. Add a new line of nameserver
XX.XX.XX.XX, using an appropriate IP address for your
environment’s DNS server.
d. Restart network services with /etc/init.d/network
restart.
2. On the Windows® 7 management system, be sure that Mozilla® Firefox® and
Bonjour® (which is included with iTunes® or downloadable from
support.apple.com/kb/DL999) are installed.

3. Determine the IPv6 service name for one of the Dell XC630 nodes that will be added
to the cluster. IPv6 service names are uniquely generated at the factory and have
the following form (note the final period): NTNX-system_service_tag-node_location-
CVM.local. On the front left side of the system is a slide-out label that contains the
system_service_tag (for example, B57PW12). The node_location is A for one-node
blocks.
4. In the Windows 7 management system, launch Mozilla Firefox, and in the URL bar,
enter http://cvm_ipv6_addr:2100/cluster_init.html, replacing
cvm_ipv6_addr with the IPv6 service name determined in step 2. For example,
the URL we accessed was http://NTNX-2PSNS52-A-
CVM.local.:2100/cluster_init.html
Note: Be careful to include the period after the word local in the URL.
Figure 5: Providing a cluster name, external IP, CVM DNS server, and CVM NTP server.
5. In the Cluster Name field, provide an appropriate name (of 15 characters or fewer)
for your Nutanix Cluster.
6. In the Cluster External IP field, provide an appropriate IP address for your Nutanix
Cluster. This IP can be used to access the web console and nCLI once the cluster is
created.

7. Leave the Cluster Max Redundancy Factor at 2, because we are using only three
nodes. A cluster must have at least five nodes to use a redundancy factor of 3, but
that configuration is beyond the scope of this guide.
8. Provide the IP address(es) of the Active Directory® domain controller(s) in the CVM
DNS Servers and CVM NTP Servers fields.
Figure 6: Providing the appropriate subnet masks and default gateways in the Cluster-wide Network
settings.
9. Provide the IP address(es) of the Active Directory domain controller(s), and in the
Hypervisor DNS Servers field, enter 8.8.8.8
10. Provide the IP address(es) of the Active Directory domain controller(s), and in the
Hypervisor NTP Servers field, enter pool.ntp.org
11. Provide the subnet masks and default gateways for each Controller, Hypervisor, and
IPMI into the Cluster-wide Network Settings table, if they are not already populated.

Figure 7: If IPv6 link-local connectivity is working properly, your nodes should appear in the list of Discovered nodes.
12. Check the box next to each node that you want to add to the cluster.
13. Provide an appropriate IP address for all the components in the cluster, if the values
are not already populated. The discovered nodes are not listed in a particular order,
so be sure to assign the intended IP addresses to each node.

Figure 8: Provide IP addresses for the Controller, Hypervisor, and IPMI for each discovered node.
14. When you are ready to create the cluster, click Create.
15. Wait until the Log Messages section of the page indicates that the cluster has been
successfully configured. The cluster starts automatically after creation succeeds.

Figure 9: Log Messages output indicating successful creation of the Nutanix cluster.
16. Log onto any Controller VM with SSH.
17. Verify that all services are up on all Controller VMs by entering the command
cluster status.
Figure 10: Verifying that all cluster services are running properly on each node in the cluster.

18. On the Windows 7 management system, enter the cluster IP address into the URL
bar, and press Enter.
19. Enter a password for the cluster admin account, and re-enter it. Click the arrow
button when finished.
Figure 11: Providing an admin password for the Nutanix cluster.
20. Enter the admin credentials at the login prompt, and click the arrow button to log
in.

Figure 12: The Nutanix Web Console dashboard page.
Configuring Nutanix storage
After creating the cluster, you must create a storage pool and a container. For
most organizations, it will be suitable to create a storage pool comprising all the physical
disks in the cluster and a container using all available capacity in the storage pool.
1. From the Nutanix Web Console main page, click the Home drop-down menu, and
select Storage.

Figure 13: The Storage drop-down menu selection.
2. Click + Storage Pool in the upper-right corner. The Create Storage Pool dialog box
appears.

Figure 14: The Nutanix Web Console Storage page.
3. Provide a name for the storage pool, and be sure that Use unallocated capacity is
checked, because that will be suitable for most environments.

Figure 15: Creating a storage pool in the Nutanix Web Console.
4. Click Save.
5. On the Storage page, click + Container. The Create Container dialog box appears.
6. Provide a name for the container, check that the container will be created in the
intended storage pool, and verify that the NFS datastore will be mounted on all ESXi
hosts. Click Save.

Figure 16: Creating a container in the Nutanix Web Console.
Configuring Dell XC630 hosts in vCenter
This guide assumes your environment has an existing deployment of VMware
vCenter Server. After creating the storage on the Nutanix cluster, add the Dell XC630
hosts to a vCenter for management. From there, configure their networking for
performance and security as per Nutanix best practices.
1. In a browser, log into the vSphere Web Client for the vCenter server.

VALIDATION AND TEST RESULTS
Nutanix storage cluster on Dell XC630 supporting all application workloads
 SQL/OLTP: 9 instances of SQL 2014 databases (3 per host) – ~420,000 OPM
 LoadGen/Exchange profile: Outlook_50 – 160 mailboxes
 Iometer – File/print workload
 Iometer – Web server workload
Our validation test showed that running nine SQL Server 2014 workloads with
DVD Store, two Microsoft Exchange Server 2013 environments, and six disk workloads
could be readily handled by a three-node cluster of Dell XC630 appliances backed by
Nutanix tiered storage. Median CPU usage on each host was 44.7 percent, so your
business would have room to grow from the configuration validated here (see Figure
24). Storage response time stayed low (3.7 milliseconds median) over the course of the
test, with some variability on node 1, which wasn’t housing an Exchange environment
(see Figure 25). Over the course of the test, the hosts’ disks put out a median of 1,089
IOPS per host, with node 1 delivering higher but more variable IOPS performance (see
Figure 26).

SUMMARY
If your business is considering using a hyperconverged
computer/storage solution rather than disparate dedicated appliances, a
Nutanix storage cluster powered by Dell XC630 appliances could bring many
benefits. Thanks to its powerful Dell servers with Intel processors, this space-
efficient solution was able to handle nine SQL Server 2014 OLTP workloads at
over 420,000 OPM, 160 mailboxes in Microsoft Exchange 2013, and file/print
and web server disk workloads; that’s enough to meet your present demands
and still have room for future growth. With software-defined tiered storage,
high availability, and a redundant network architecture, the hyperconverged
solution based on Dell XC630 appliances can help your business get the job
done.

APPENDIX B – DETAILED CONFIGURATION METHODOLOGY
Configuring application VMs
In this section, we walk through how to configure the applications we tested. We created and configured VMs
for Exchange Server 2013, SQL Server 2014, and Iometer for ESXi via the vSphere Web Client. The Exchange CAS VMs
were configured with two vCPUs and 16 GB of RAM, and the Exchange Mailbox VMs were configured with four vCPUs
and 16 GB of RAM. Each SQL Server 2014 VM was configured with four vCPUs and 8 GB of RAM, and each Iometer VM
was configured with one vCPU and 4 GB of RAM.
Creating VMs for ESXi in the vSphere Web Client
We used the vSphere Web Client to create the VMs for our application environments. Here we walk through
creating a sample VM, providing generic details about the virtual hardware, which can be customized as necessary. We
created the VMs on the host we wanted them to reside on, though the host for each VM can be changed after creation.
1. Log into the vSphere Web Client in a browser with administrator credentials.
2. Right-click the host on which you want to create the new VM, and select New Virtual MachineNew

Installing Exchange Server 2013 SP1 Mailbox and Client Access Server roles
We created two VMs each to serve as Mailbox and CAS servers for our Exchange environments and edited the
hardware settings in each. The Mailbox servers had four vCPUs and 16 GB of memory, and the CAS servers had two
vCPUs and 16 GB of memory. We also provided the Mailbox VMs with a 200GB data disk and a 200GB logs disk each for
Exchange’s database and logs, respectively. We gave each CAS VM a 100GB disk onto which we would install Exchange.
We set static IPs on all the VMs and joined the domain. We ran the following commands on both Mailbox VMs and both
CAS VMs as appropriate. By the end of these steps, we had two functional and separate Exchange Server setups, sharing
an Active Directory.

1. On each Mailbox and CAS server, log into the server using domain administrator credentials.

Configuring the database workload client
For our testing, we used a virtual client for the Microsoft SQL Server client. To create this client, we installed
Windows Server 2008 R2, assigned a static IP address, and installed .NET 3.5.
Configuring the database
We generated the data using the Install.pl script included with DVD Store version 2.1 (DS2), providing the
parameters for our 4GB database size and the database platform on which we ran, Microsoft SQL Server 2014. We ran
the Install.pl script on a utility system running Linux®. The database schema was also generated by the Install.pl script.
After processing the data generation, we transferred the data files and schema creation files to a Windows-
based system running SQL Server 2014. We built the database in SQL Server 2014, and performed a full backup, storing
the backup file on the C: drive for quick access. We used that backup file to restore the server between test runs.
The only modification we made to the schema creation scripts were the specified file sizes for our database. We
deliberately set the file sizes higher than necessary to ensure that no file-growth activity would affect the outputs of the
test. Besides this file size modification, the database schema was created and loaded according to the DVD Store
documentation. Specifically, we performed the following steps:
1. We generated the data and created the database and file structure using database creation scripts in the
DS2 download. We made size modifications specific to our database and the appropriate changes to drive
letters.
2. We transferred the files from our Linux data generation system to a Windows system running SQL Server.
3. We created database tables, stored procedures, and objects using the provided DVD Store scripts.
4. We set the database recovery model to bulk-logged to prevent excess logging.
5. We loaded the data we generated into the database. For data loading, we used the import wizard in SQL
Server Management Studio. Where necessary, we retained options from the original scripts, such as Enable
Identity Insert.
6. We created indices, full-text catalogs, primary keys, and foreign keys using the database-creation scripts.
7. We updated statistics on each table according to database-creation scripts, which sample 18 percent of the
table data.
8. On the SQL Server instance, we created a ds2user SQL Server login using the following Transact SQL (TSQL)
script:
USE [master]
GO
CREATE LOGIN [ds2user] WITH PASSWORD=N’’,
DEFAULT_DATABASE=[master],
DEFAULT_LANGUAGE=[us_english],
CHECK_EXPIRATION=OFF,
CHECK_POLICY=OFF
GO

9. We set the database recovery model back to full.
10. We created the necessary full text index using SQL Server Management Studio.
11. We created a database user and mapped this user to the SQL Server login.
12. We performed a full backup of the database. This backup allowed us to restore the databases to a pristine
state relatively quickly between tests.
Running the test
Test start and run times
We ran the workloads with one client per target database. The specific testing parameters we used for the
benchmark are included below.
Running the DVD Store tests
We created a series of batch files, SQL scripts, and shell scripts to automate the complete test cycle. DVD Store
outputs an orders-per-minute metric, which is a running average calculated through the test. In this report, we report
the aggregate OPM reported by the clients for each run.
Each complete test cycle consisted of the general steps listed below.
1. Clean up prior outputs from the target system and the client driver system.
2. Drop the database from the target servers.
3. Restore the database on the target servers.
4. Shut down the target.
5. Reboot the host and client systems.
6. Wait for a ping response from the server under test (the hypervisor system), the client system, and the
target.
7. Let the test server idle for 10 minutes.
8. Start the DVD Store driver on each client.
We used the following DVD Store parameters for testing:
ds2sqlserverdriver.exe --target=<target_IP> --ramp_rate=10 --run_time=20
--n_threads=64 --db_size=4GB --think_time=0 --detailed_view=Y --
warmup_time=10 --csv_output=<drive path>

ABOUT PRINCIPLED TECHNOLOGIES
We provide industry-leading technology assessment and fact-based
marketing services. We bring to every assignment extensive experience
with and expertise in all aspects of technology testing and analysis, from
researching new technologies, to developing new methodologies, to
testing with existing and new tools.
When the assessment is complete, we know how to present the results
to a broad range of target audiences. We provide our clients with the
materials they need, from market-focused data to use in their own
collateral to custom sales aids, such as test reports, performance
assessments, and white papers. Every document reflects the results of
our trusted independent analysis.
We provide customized services that focus on our clients’ individual
requirements. Whether the technology involves hardware, software,
Web sites, or services, we offer the experience, expertise, and tools to
help our clients assess how it will fare against its competition, its
performance, its market readiness, and its quality and reliability.
Our founders, Mark L. Van Name and Bill Catchings, have worked
together in technology assessment for over 20 years. As journalists,
they published over a thousand articles on a wide array of technology
subjects. They created and led the Ziff-Davis Benchmark Operation,
which developed such industry-standard benchmarks as Ziff Davis
Media’s Winstone and WebBench. They founded and led eTesting Labs,
and after the acquisition of that company by Lionbridge Technologies
were the head and CTO of VeriTest.
