Cisco Validated Designs (CVDs) consist of systems and solutions that are designed, tested, and documented to facilitate and improve customer deployments. These designs incorporate a wide range of technologies and products into a portfolio of solutions that have been developed to address the business needs of our customers.

This document details the design described in the FlashStack Virtual Server Infrastructure for VMware vSphere 6.7 Update 1 Design Guide, which details a validated converged infrastructure jointly developed by Cisco and Pure Storage.  In this solution, we explain the deployment of a predesigned, best-practice data center architecture with VMware vSphere built on Cisco Unified Computing System (Cisco UCS), the Cisco Nexus® 9000 family of switches, and Pure Storage FlashArray//X Series all flash storage configured for iSCSI based storage access.

When deployed, the architecture presents a robust infrastructure viable for a wide range of application workloads implemented as a virtual server infrastructure.

Introduction

Currently in our industry, there is a trend for pre-engineered solutions which standardize the data center infrastructure, offering the business operational efficiencies, agility, and scale to address cloud, bi-modal IT and their business needs.  The challenge is complexity, diverse application support, efficiency and risk; all these are met by FlashStack with:

·         Reduced complexity and automatable infrastructure and easily deployed resources

·         Robust components capable of supporting high performance and high bandwidth virtualized applications

·         Efficiency through optimization of network bandwidth and in-line storage compression with de-duplication

·         Risk reduction at each level of the design with resiliency built into each touch point throughout

Cisco and Pure Storage have partnered to deliver this Cisco Validated Design, combining storage, server and network components to serve as the foundation for virtualized workloads, enabling efficient architectural designs that can be quickly and confidently deployed. 

In this document we will describe a reference architecture detailing a virtual server infrastructure composed of Cisco Nexus switches, Cisco UCS Compute, and a Pure Storage FlashArray//X R2 delivering a VMware vSphere 6.7 Update1 hypervisor environment.

Audience

The audience for this document includes, but is not limited to; sales engineers, field consultants, professional services, IT managers, partner engineers, and customers who want to modernize their infrastructure to meet their business needs

Purpose of this Document

This document details a step-by-step configuration and implementation guide for FlashStack, centered around the Cisco UCS 6454 Fabric Interconnect and the Pure Storage FlashArray//X70 R2.  These components are supported by the 100G capable Cisco Nexus 9336C-FX2 switch to deliver a Virtual Server infrastructure on Cisco UCS B200 M5 Blade Servers and Cisco UCS C220 M5 Rack Servers running VMware vSphere 6.7 U1. 

The design that will be implemented is discussed in the FlashStack Virtual Server Infrastructure for VMware vSphere 6.7 Update 1 Design Guide.

Solution Summary

The FlashStack Virtual Server Infrastructure is a validated reference architecture, collaborated on by Cisco and Pure Storage, built to serve enterprise data centers.  The solution is built to deliver a VMware vSphere based environment, leveraging Cisco Unified Computing System (Cisco UCS), Cisco Nexus switches, and Pure Storage FlashArray.

The architecture brings together a simple, wire-once solution that is SAN booted from iSCSI and is highly resilient at each layer of the design. This creates an infrastructure that is ideal for a variety of virtual application deployments that can reliably scale when growth is needed.

 

Figure 1 illustrates the base physical architecture used in FlashStack Virtual Server Infrastructure.

Figure 1  FlashStack with Cisco UCS 6454 and Pure Storage FlashArray //70 R2

The reference hardware configuration includes:

·         Two Cisco Nexus 9336C-FX2 Switches

·         Two Cisco UCS 6454 Fabric Interconnects

·         Cisco UCS 5108 Chassis with two Cisco UCS 2308 Fabric Extenders

·         Two Cisco UCS B200 M5 Blade Servers

·         Four Cisco UCS C220 M5 Rack Servers

·         One Pure Storage FlashArray//X70 R2

The virtual environment this supports is within VMware vSphere 6.7 U1 and includes virtual management and automation components from Cisco and Pure Storage built into the solution, or as optional add-ons.

This document will provide a low-level example of steps to deploy this base architecture that may need some adjustments depending on the customer environment. These steps include physical cabling, network, storage, compute, and virtual device configurations.

Table 1 lists the software versions for hardware and virtual components used in this solution.  Each of these versions have been certified within interoperability matrixes supported by Cisco, Pure Storage, and VMware.  For additional supported version information, consult the following sources:

·         Cisco UCS Hardware and Software Interoperability Tool: http://www.cisco.com/web/techdoc/ucs/interoperability/matrix/matrix.html

·         Pure Storage Interoperability(note, this interoperability list will require a support login from Pure):  https://support.purestorage.com/FlashArray/Getting_Started/Compatibility_Matrix

·         Pure Storage FlashStack Compatibility Matrix (note, this interoperability list will require a support login from Pure): https://support.purestorage.com/FlashStack/Product_Information/FlashStack_Compatibility_Matrix

·         VMware Compatibility Guide: http://www.vmware.com/resources/compatibility/search.php

·         Additionally, it is also strongly suggested to align FlashStack deployments with the recommended release for the Cisco Nexus 9000 switches used in the architecture:

-        Cisco Nexus: 
https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/recommended_release/b_Minimum_and_Recommended_Cisco_NX-OS_Releases_for_Cisco_Nexus_9000_Series_Switches.html

If the selected versions differ from the validated versions listed in Table 1, it is highly recommended to read the release notes of the selected version to be aware of any changes to features or commands.

Configuration Guidelines

This document details the step-by-step configuration of a fully redundant and highly available virtual server infrastructure built on Cisco and Pure Storage components.  References are made to which component is configured with each step, either 01 or 02 or A and B. For example, controller-1 and controller-2 are used to identify the two controllers within the Pure Storage FlashArray//X that are provisioned in this document, and Cisco Nexus A or Cisco Nexus B identifies the pair of Cisco Nexus switches that are configured. The Cisco UCS fabric interconnects are similarly configured. Additionally, this document details the steps for provisioning multiple Cisco UCS hosts, and these examples are identified as: VM-Host-iSCSI-01, VM-Host-iSCSI-02 to represent iSCSI booted infrastructure and production hosts deployed to the fabric interconnects in this document. Finally, to indicate that you should include information pertinent to your environment in a given step, <<text>> appears as part of the command structure. See the following example during a configuration step for both Nexus switches:

AA12-9336C-A&B (config)# ntp server <<var_oob_ntp>> use-vrf management

This document is intended to enable you to fully configure the customer environment. In this process, various steps require you to insert customer-specific naming conventions, IP addresses, and VLAN schemes, as well as to record appropriate MAC addresses. Table 2 describes the VLANs necessary for deployment as outlined in this guide, and Table 3 lists the virtual machines (VMs) necessary for deployment as outlined in this guide.

Physical Topology

This section details a cabling example for a FlashStack environment. To make connectivity clear in this example, the tables include both the local and remote port locations.

This document assumes that out-of-band management ports are plugged into an existing management infrastructure at the deployment site.  The upstream network from the Nexus 9336C-FX2 switches is out of scope of this document, with only the assumption that these switches will connect to the upstream switch or switches with a vPC.

Figure 2 shows the cabling configuration used in this FlashStack design.

Network Configuration

The following procedures describe how to configure the Cisco Nexus switches for use in a base FlashStack environment.  This procedure assumes the use of Nexus 9336C-FX2 switches running 7.0(3)I7(5).  Configuration on a differing model of Nexus 9000 series switch should be comparable but may differ slightly with model and changes in NX-OS release.  The Cisco Nexus 9336C-FX2 switch and NX-OS 7.0(3)I7(5) release were used in validation of this FlashStack solution, so steps will reflect this model and release.

Physical Connectivity

Physical cabling should be completed by following the diagram and table references in the previous section referenced as FlashStack Cabling.

Cisco Nexus Basic System Configuration Dialog

Pure Storage FlashArray//X70 R2 Configuration

FlashArray Initial Configuration

The information listed in Table 11 should be gathered to enable the installation and configuration of the FlashArray. An official representative of Pure Storage or a Certified Partner will help rack and configure the new installation of the FlashArray.

Table 11       FlashArray Setup Information

When the FlashArray has completed initial configuration, it is important to configure the Cloud Assist phone-home connection to provide the best pro-active support experience possible. Furthermore, this will enable the analytics functionalities provided by Pure1.

Add an Alert Recipient

The Alerts sub-view is used to manage the list of addresses to which Purity delivers alert notifications, and the attributes of alert message delivery. You can designate up to 19 alert recipients. The Alert Recipients section displays a list of email addresses that are designated to receive Purity alert messages. Up to 20 alert recipients can be designated. The list includes the built-in flasharray-alerts@purestorage.com address, which cannot be deleted.

The email address that Purity uses to send alert messages includes the sender domain name and is comprised of the following components:

<Array_Name>-<Controller_Name>@<Sender_Domain_Name>.com

To add an alert recipient, follow these steps:

1.        Select Settings

2.       In the Alert Watchers section, enter the email address of the alert recipient and click the + icon.

The Relay Host section displays the hostname or IP address of an SMTP relay host, if one is configured for the array. If you specify a relay host, Purity routes the email messages via the relay (mail forwarding) address rather than sending them directly to the alert recipient addresses.

In the Sender Domain section, the sender domain determines how Purity logs are parsed and treated by Pure Storage Support and Escalations. By default, the sender domain is set to the domain name please-configure.me.

It is crucial that you set the sender domain to the correct domain name. If the array is not a Pure Storage test array, set the sender domain to the actual customer domain name. For example, mycompany.com.

Configure Pure1 Support

The Pure1 Support section manages the phone home facility. The phone home facility provides a secure direct link between the array and the Pure Storage Technical Support web site. The link is used to transmit log contents and alert messages to the Pure Storage Support team so that when diagnosis or remedial action is required, complete recent history about array performance and significant events is available.

The Remote Assist section displays the remote assist status as "Connected" or "Disconnected". By default, remote assist is disconnected. A connected remote assist status means that a remote assist session has been opened, allowing Pure Storage Support to connect to the array. Disconnect the remote assist session to close the session.

By default, the phone home facility is enabled. If the phone home facility is enabled to send information automatically, Purity transmits log and alert information directly to Pure Storage Support via a secure network connection. Log contents are transmitted hourly and stored at the support web site, enabling detection of array performance and error rate trends. Alerts are reported immediately when they occur so that timely action can be taken.

Phone home logs can also be sent to Pure Storage Technical support on demand, with options including Today's Logs, Yesterday's Logs, or All Log History.

The Support Logs section allows you to download the Purity log contents of the specified controller to the current administrative workstation. Purity continuously logs a variety of array activities, including performance summaries, hardware and operating status reports, and administrative actions.

Configure the Domain Name System (DNS) Server IP Addresses

To configure the DNS server IP addresses, follow these steps:

1.        Select Settings > Network.

2.       In the DNS section, hover over the domain name and click the pencil icon. The Edit DNS dialog box appears.

3.        Complete the following fields:

a.        Domain: Specify the domain suffix to be appended by the array when doing DNS lookups.

b.       NS#: Specify up to three DNS server IP addresses for Purity to use to resolve hostnames to IP addresses. Enter one IP address in each DNS# field. Purity queries the DNS servers in the order that the IP addresses are listed.

4.       Click Save.

iSCSI Interface Configuration

The iSCSI traffic will be carried on two VLANs, A (901) and B (902) that are configured in our example with the following values:

Table 12      iSCSI A FlashArray//X70 R2 Interface Configuration Settings

Table 13       iSCSI B FlashArray//X70 R2 Interface Configuration Settings

To configure iSCSI interfaces for environments deploying iSCSI boot LUNs and/or datastores, follow these steps:

1.        Select Settings > Network.

2.       Click the .

3.        Select the Enabled check mark box within the Edit Network Interface dialogue window, enter the Address and Netmask from Table 12, and set the MTU to 9000 to enable jumbo frames.

4.       Click Save.

5.        Repeat steps 1-4 for ct0.eth15, ct1.eth14, and ct1.eth15 using values from Table 12 and Table 13.

Directory Service Sub-view

The Directory Service sub-view manages the integration of FlashArray with an existing directory service. When the Directory Service sub-view is configured and enabled, the FlashArray leverages a directory service to perform user account and permission level searches. Configuring directory services is OPTIONAL.

The FlashArray is delivered with a single local user, named pureuser, with array-wide (Array Admin) permissions.

To support multiple FlashArray users, integrate the array with a directory service, such as Microsoft Active Directory or OpenLDAP.

Role-based access control is achieved by configuring groups in the directory that correspond to the following permission groups (roles) on the array:

·         Read Only Group. Read Only users have read-only privilege to run commands that convey the state of the array. Read Only uses cannot alter the state of the array.

·         Storage Admin Group. Storage Admin users have all the privileges of Read Only users, plus the ability to run commands related to storage operations, such as administering volumes, hosts, and host groups. Storage Admin users cannot perform operations that deal with global and system configurations.

·         Array Admin Group. Array Admin users have all the privileges of Storage Admin users, plus the ability to perform array-wide changes. In other words, Array Admin users can perform all FlashArray operations.

To configure and enable the Directory Service sub-view, follow these steps:

1.         Select Settings > Users.

2.       Select the  icon in the Directory Services panel:

a.        Enabled: Select the check box to leverage the directory service to perform user account and permission level searches.

b.       URI: Enter the comma-separated list of up to 30 URIs of the directory servers. The URI must include a URL scheme (ldap, or ldaps for LDAP over SSL), the hostname, and the domain. You can optionally specify a port. For example, ldap://ad.company.com configures the directory service with the hostname "ad" in the domain "company.com" while specifying the unencrypted LDAP protocol.

c.        Base DN: Enter the base distinguished name (DN) of the directory service. The Base DN is built from the domain and should consist only of domain components (DCs). For example, for ldap://ad.storage.company.com, the Base DN would be: “DC=storage,DC=company,DC=com”

d.       Bind User: Username used to bind to and query the directory. For Active Directory, enter the username - often referred to as sAMAccountName or User Logon Name - of the account that is used to perform directory lookups. The username cannot contain the characters " [ ] : ; | = + * ? < > / \ and cannot exceed 20 characters in length. For OpenLDAP, enter the full DN of the user. For example, "CN=John,OU=Users,DC=example,DC=com".

e.       Bind Password: Enter the password for the bind user account.

f.         Group Base: Enter the organizational unit (OU) to the configured groups in the directory tree. The Group Base consists of OUs that, when combined with the base DN attribute and the configured group CNs, complete the full Distinguished Name of each groups. The group base should specify "OU=" for each OU and multiple OUs should be separated by commas. The order of OUs should get larger in scope from left to right. In the following example, SANManagers contains the sub-organizational unit PureGroups: "OU=PureGroups,OU=SANManagers".

g.       Array Admin Group: Common Name (CN) of the directory service group containing administrators with full privileges to manage the FlashArray. Array Admin Group administrators have the same privileges as pureuser. The name should be the Common Name of the group without the "CN=" specifier. If the configured groups are not in the same OU, also specify the OU. For example, "pureadmins,OU=PureStorage", where pureadmins is the common name of the directory service group.

h.       Storage Admin Group: Common Name (CN) of the configured directory service group containing administrators with storage related privileges on the FlashArray. The name should be the Common Name of the group without the "CN=" specifier. If the configured groups are not in the same OU, also specify the OU. For example, "pureusers,OU=PureStorage", where pureusers is the common name of the directory service group.

i.         Read Only Group: Common Name (CN) of the configured directory service group containing users with read-only privileges on the FlashArray. The name should be the Common Name of the group without the "CN=" specifier. If the configured groups are not in the same OU, also specify the OU. For example, "purereadonly,OU=PureStorage", where purereadonly is the common name of the directory service group.

j.         Check Peer: Select the check box to validate the authenticity of the directory servers using the CA Certificate. If you enable Check Peer, you must provide a CA Certificate.

k.        CA Certificate: Enter the certificate of the issuing certificate authority. Only one certificate can be configured at a time, so the same certificate authority should be the issuer of all directory server certificates. The certificate must be PEM formatted (Base64 encoded) and include the "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----" lines. The certificate cannot exceed 3000 characters in total length.

3.        Click Save.

4.       Click Test to test the configuration settings. The LDAP Test Results pop-up window appears. Green squares represent successful checks. Red squares represent failed checks.

SSL Certificate Sub-view

Purity creates a self-signed certificate and private key when you start the system for the first time. The SSL Certificate sub-view allows you to view and change certificate attributes, create a new self-signed certificate, construct certificate signing requests, import certificates and private keys, and export certificates.

Creating a self-signed certificate replaces the current certificate. When you create a self-signed certificate, include any attribute changes, specify the validity period of the new certificate, and optionally generate a new private key.

When you create the self-signed certificate, you can generate a private key and specify a different key size. If you do not generate a private key, the new certificate uses the existing key.

You can change the validity period of the new self-signed certificate. By default, self-signed certificates are valid for 3650 days

CA-Sign Certificate

Certificate Authorities (CA) are third party entities outside the organization that issue certificates. To obtain a CA certificate, you must first construct a certificate signing request (CSR) on the array.

The CSR represents a block of encrypted data specific to your organization. You can change the certificate attributes when you construct the CSR; otherwise, Purity will reuse the attributes of the current certificate (self-signed or imported) to construct the new one. Note that the certificate attribute changes will only be visible after you import the signed certificate from the CA.

Send the CSR to a certificate authority for signing. The certificate authority returns the SSL certificate for you to import. Verify that the signed certificate is PEM formatted (Base64 encoded), includes the "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----" lines, and does not exceed 3000 characters in total length. When you import the certificate, also import the intermediate certificate if it is not bundled with the CA certificate.

If the certificate is signed with the CSR that was constructed on the current array and you did not change the private key, you do not need to import the key. However, if the CSR was not constructed on the current array or if the private key has changed since you constructed the CSR, you must import the private key. If the private key is encrypted, also specify the passphrase.

Cisco UCS Compute Configuration

The following procedures describe how to configure the Cisco UCS domain for use in a base FlashStack environment.  This procedure assumes the use of UCS Fabric Interconnects running 4.0(2b).  Configuration on a different model of Cisco UCS Fabric Interconnects should be comparable but may differ slightly with model and changes in the UCSM release.  The Cisco USC 6454 Fabric Interconnects and Cisco UCS Manger 4.0(2b) release were used in validation of this FlashStack solution, so the steps will reflect this model and release.
