HyperFlex Edge Deployments

Cisco HyperFlex Edge brings the simplicity of hyperconvergence to remote and branch office (ROBO) and edge environments.

Starting with Cisco HX Data Platform Release 4.0, HyperFlex Edge deployments can be based on 2-Node, 3-Node, or 4-Node Edge clusters. For the key requirements and supported topologies that must be understood and configured before starting a Cisco HyperFlex Edge deployment, refer the Preinstallation Checklist for Cisco HyperFlex Edge.

Cisco HyperFlex Pre-Install Interactive Tool

Cisco recommends using the HyperFlex Pre-Install Tool https://hxpreinstall.cloudapps.cisco.com/ for pre-deployment planning. The tool enables a collection of HyperFlex cluster configuration parameters and enables a simple configuration transfer to either Intersight SaaS or the HyperFlex installer VM. The features and benefits of using the HyperFlex Pre-Install tool include:

- Create and validate a cluster configuration before starting installation.

- Multi-cluster import capability using a Microsoft Excel template.

- Push the cluster configuration directly to Intersight SaaS, resulting in automatic cluster profile creation.

- Download JSON configuration files for use with the HyperFlex OVA installer VM.

- Creation of PDF reports with the configuration for record keeping.

- Clone a cluster profile for easy scaling.

Physical Requirements

Physical Server Requirements

- For a HX220c/HXAF220c Cluster:

- Two rack units (RU) for the UCS 6248UP, 6332UP, 6332-16UP Fabric Interconnects (FI) or four RU for the UCS 6296UP FI

- HX220c Nodes are one RU each; for example, for a three-node cluster, three RU are required; for a four-node cluster, 4 RU are required

- If a Top-of-Rack switch is included in the install, add at least two additional RU of space for the switch.

- For a HX240c/HXAF240c Cluster:

- Two rack units (RU) for the UCS 6248UP, 6332UP, 6332-16UP Fabric Interconnects (FI) or four RU for the UCS 6296UP FI

- HX240c Nodes are two RU each; for example, for a three-node cluster, six RU are required; for a four-node cluster, eight RU are required

- If a Top-of-Rack switch is included in the install, add at least two additional RU of space for the switch.

Although there is no requirement for contiguous rack space, it makes installation easier.

- The system requires two C13/C14 power cords connected to a 15-amp circuit per device in the cluster. At a minimum, there are three HX nodes and two FI, and it can scale to eight HX nodes, two FI, and blade chassis.

- Up to 2 - 4x uplink connections for UCS Fabric Interconnects.

- Per best practice, each FI requires either 2x10 Gb optical connections in an existing network, or 2x10 Gb Twinax cables. Each HX node requires two Twinax cables for connectivity (10 Gb optics can be used). For deployment with 6300 series FI, use 2x40GbE uplinks per FI and connect each HX node with dual native 40GbE.

- VIC and NIC Support: For details, see the Cisco HyperFlex Systems—Networking Topologies document.

Note

Single FI HX deployment is not supported.

Network Requirements

Verify that your environment adheres to the following best practices:

- Must use a different subnet and VLANs for each network.

- Verify that each host directly attaches to a UCS Fabric Interconnect using an appropriate cable.

- Do not use VLAN 1, the default VLAN, because it can cause networking issues, especially if Disjoint Layer 2 configuration is used. Use a different VLAN.

Important

Reserved VLAN IDs- VLANs with IDs from 4030 to 4047 and from 4094 to 4095 are reserved in UCS. You cannot use VLANs with IDs from this range. Until Cisco UCS Manager Release 4.0(1d), VLAN ID 4093 was in the list of reserved VLANs. VLAN 4093 has been removed from the list of reserved VLANs and is available for configuration.

The VLAN IDs you specify must also be supported on the uplink switch that you are using. For example, VLAN IDs 3968 to 4095 are reserved by Nexus switches and VLAN IDs 1002 to 1005 are reserved by Catalyst switches. Before you decide the VLAN IDs for HyperFlex use, make sure that the same VLAN IDs are available on your uplink switch.

- Configure the upstream switches to accommodate non-native VLANs. Cisco HX Data Platform Installer sets the VLANs as non-native by default.

- Uplinks from the UCS Fabric Interconnects to all top of rack switch ports must configure spanning tree in edge trunk or portfast edge mode depending on the vendor and model of the switch. This extra configuration ensures that when links flap or change state, they do not transition through unnecessary spanning tree states and incur an extra delay before traffic forwarding begins. Failure to properly configure FI uplinks in portfast edge mode may result in network and cluster outages during failure scenarios and during infrastructure upgrades that leverage the highly available network design native to HyperFlex.

Each VMware ESXi host needs the following separate networks:

- Management traffic network—From the VMware vCenter, handles hypervisor (ESXi server) management and storage cluster management.

- Data traffic network—Handles the hypervisor and storage data traffic.

- vMotion network

- VM network

There are four vSwitches, each one carrying a different network:

- vswitch-hx-inband-mgmt—Used for ESXi management and storage controller management.

- vswitch-hx-storage-data—Used for ESXi storage data and HX Data Platform replication.

The vswitch-hx-inband-mgmt and vswitch-hx-storage-data vSwitches further divide into two port groups with assigned static IP addresses to handle traffic between the storage cluster and ESXi host.

- vswitch-hx-vmotion—Used for VM and storage VMware vMotion.

This vswitch has one port group for management, defined through VMware vSphere, which connects to all hosts in the vCenter cluster.

- vswitch-hx-vm-network—Used for VM data traffic.

You can add or remove VLANs on the corresponding vNIC templates in Cisco UCS Manager and create port groups on the vswitch.

Note

- Cisco HX Data Platform Installer creates the vSwitches automatically.

- Ensure that you enable the following services in vSphere after you create the HX Storage Cluster using post_install script. For details on the post_install script, see Run Post-Installation Script .

- DRS (vSphere Enterprise Plus only)

- vMotion

- High Availability

Port Requirements

If your network is behind a firewall, in addition to the standard port requirements, VMware recommends ports for VMware ESXi and VMware vCenter.

- CIP-M is for the cluster management IP.

- SCVM is the management IP for the controller VM.

- ESXi is the management IP for the hypervisor.

The comprehensive list of ports required for component communication for the HyperFlex solution is located in Appendix A of the HX Data Platform Security Hardening Guide

Tip

If you do not have standard configurations and need different port settings, refer to Appendix A of the HX Data Platform Security Hardening Guide for customizing your environment.

HyperFlex External Connections

External Connection

Description

IP Address/ FQDN/ Ports/Version

Essential Information

Intersight Device Connector

Supported HX systems are connected to Cisco Intersight through a device connector that is embedded in the management controller of each system.

HTTPS Port Number: 443

1.0.5-2084 or later (Auto-upgraded by Cisco Intersight)

All device connectors must properly resolve svc.intersight.com and allow outbound-initiated HTTPS connections on port 443. The current HX Installer supports the use of an HTTP proxy.

The IP addresses of ESXi management must be reachable from Cisco UCS Manager over all the ports that are listed as being needed from installer to ESXi management, to ensure deployment of ESXi management from Cisco Intersight.

Note

Outbound HTTPS connections on port 443 initiated by ESXi hosts can be blocked by the default ESXi firewall. The ESXi firewall can be temporarily disabled to allow this connectivity.

To disable the ESXi firewall, use the esxcli network firewall set --enabled=false command and after the installation has completed use the esxcli network firewall set --enabled=false command to re-enable the firewall.

For more information, see the Network Connectivity Requirements section of the Intersight Help Center.

Auto Support

Auto Support (ASUP) is the alert notification service provided through HX Data Platform.

SMTP Port Number: 25

Enabling Auto Support is strongly recommended because it provides historical hardware counters that are valuable in diagnosing future hardware issues, such as a drive failure for a node.

- Intersight Connectivity

Intersight Connectivity

Consider the following prerequisites pertaining to Intersight connectivity:

- Before installing the HX cluster on a set of HX servers, make sure that the device connector on the corresponding Cisco IMC instance is properly configured to connect to Cisco Intersight and claimed.

- Communication between CIMC and vCenter via ports 80, 443 and 8089 during installation phase.

- All device connectors must properly resolve svc.intersight.com and allow outbound initiated HTTPS connections on port 443. The current version of the HX Installer supports the use of an HTTP proxy.

- All controller VM management interfaces must properly resolve svc.intersight.com and allow outbound initiated HTTPS connections on port 443. The current version of HX Installer supports the use of an HTTP proxy if direct Internet connectivity is unavailable.

- IP connectivity (L2 or L3) is required from the CIMC management IP on each server to all of the following: ESXi management interfaces, HyperFlex controller VM management interfaces, and vCenter server. Any firewalls in this path should be configured to allow the necessary ports as outlined in the Hyperflex Hardening Guide.

- When redeploying HyperFlex on the same servers, new controller VMs must be downloaded from Intersight into all ESXi hosts. This requires each ESXi host to be able to resolve svc.intersight.com and allow outbound initiated HTTPS connections on port 443. Use of a proxy server for controller VM downloads is supported and can be configured in the HyperFlex Cluster Profile if desired.

- Post-cluster deployment, the new HX cluster is automatically claimed in Intersight for ongoing management.

Until Cisco UCS Manager Release 4.0(1d), VLAN ID 4093 was in the list of reserved VLANs. VLAN 4093 has been removed from the list of reserved VLANs and is available for configuration.

The VLAN IDs you specify must also be supported on the uplink switch that you are using. For example, VLAN IDs 3968 to 4095 are reserved by Nexus switches and VLAN IDs 1002 to 1005 are reserved by Catalyst switches. Before you decide the VLAN IDs for HyperFlex use, make sure that the same VLAN IDs are available on your uplink switch.

Customer Deployment Information

Deploy the HX Data Platform using an OVF installer appliance. A separate ESXi server, which is not a member of the vCenter HX Cluster, is required to host the installer appliance. The installer requires one IP address on the management network.

The installer appliance IP address must be reachable from the management subnet used by the hypervisor and the storage controller VMs. The installer appliance must run on the ESXi host or on a VM Player/VMware workstation that is not a part of the cluster installation. In addition, the HX Data Platform Installer VM IP address must be reachable by Cisco UCS Manager, ESXi, and vCenter IP addresses where HyperFlex hosts are added.

Installer appliance IP address

Network IP Addresses

Note

- Data network IPs in the range of 169.254.X.X in a network larger than /24 is not supported and should not be used.

- Data network IPs in the range of 169.254.254.0/24 must not be used.

- This is automatic for ESXi version 6.0 and later.

* SSO Server URL can be found in vCenter at vCenter Server > Manage > Advanced Settings, key config.vpxd.sso.sts.uri.

Network Services

Note

- At least one DNS and NTP server must reside outside of the HX storage cluster.

- Use an internally hosted NTP server to provide a reliable source for the time.

- All DNS servers should be pre-configured with forward (A) and reverse (PTR) DNS records for each ESXi host before starting deployment. When DNS is configured correctly in advance, the ESXi hosts are added to vCenter via FQDN rather than IP address.

Skipping this step will result in the hosts being added to the vCenter inventory via IP address and require users to change to FQDN using the following procedure: Changing Node Identification Form in vCenter Cluster from IP to FQDN.

- Custom HyperFlex Controller Hostname: If you would like to set custom host names for the HyperFlex controller VMs, make sure to pre-configure DNS servers with forward (A) and reverse (PTR) DNS records for each controller management IP before starting deployment. If a valid DNS record is not found, the installer will set the controller hostname as SpringpathController and 10 random digits/uppercase letters.
