Ensure that there is network isolation for the Virtual Controller storage and federation network interfaces between clusters when more than one cluster is deployed within a federation.

To use NIC teaming, you must uplink two or more adapters to a virtual switch. You can also find details on the VMware Knowledge Base site kb. Use Port ID for all other cases. Direct connect clusters Direct connect clusters can be used in a one- or two-node configurations. The 10GbE ports are used exclusively for storage and federation traffic. This must be configured after deployment is complete. Full mesh With a full mesh topology, every HPE OmniStack host in every cluster in the federation can communicate directly with every other host in the federation.

This configuration enables backup and restore operations to be performed between each cluster in the federation. In this configuration, all the clusters can communicate directly with the main, centralized clusters, but the remote spoke clusters do not have direct communication with each other. This configuration is also known as a hub-and-spoke topology. Data movement operations such as moving a virtual machine, restoring a virtual machine or file from a backup, or copying a backup to another cluster are restricted to directly connected clusters.

So, in a hub-and-spoke topology, these operations cannot be performed between spoke clusters that are not directly connected. TABLE 5. This is provided with the use of availability zones, which are collections of hosts that share a common fault-mode.

As an administrator, you define these zones to tell the HPE OmniStack software the nodes that are likely to fail together due to external forces.

By configuring an equal number of hosts within two availability zones, and leveraging a third site arbiter, you will not lose access to data following a failure that impacts one of these zones. Stretch clusters ensure fully committed synchronous writes between two physical sites by only acknowledging writes back to the VM after nodes at both sites have safely persisted the write.

In a stretch cluster environment, you should deploy the Arbiter in a location that is outside the failure domain of both data centers. Higher latencies can be deployed depending on application performance requirements. WAN link congestion can adversely affect the number of backups that might be replicated to a remote cluster.

If replication fails to complete within the backup window or retention period, check if there is sufficient network throughput. The Arbiter ensures data availability and integrity by serving as an additional quorum member in two-node and stretch cluster configurations. This arbitration ensures the resiliency of the federation. The Arbiter can manage up to 4, virtual machines. To ensure best performance, install an Arbiter for every 4, virtual machines and associate it with one or more clusters in a federation to distribute the workload.

In stretch clusters, it is important that the arbiter is installed outside of the failure domain of the hosts that is it arbitrating. For example, suppose that you have deployed HPE OmniStack hosts in two clusters cluster 1 and cluster 2 ; you can deploy the Arbiter on a Windows host that has network access to both clusters.

HPE SimpliVity Arbiter on a Windows host that has network access to both clusters Alternatively, you can deploy an Arbiter within each cluster that manages the other cluster. In that configuration, you would not need a separate Windows host.

In a two-node cluster scenario, if the Arbiter were to be deployed as a virtual machine within the same cluster that it is supporting, a complete data unavailability would occur if its ESXi server were to go down. This failure would prohibit the surviving node from establishing quorum. For this reason, the Arbiter should be installed on a separate host outside of the cluster that it supports. In a multi-data center environment, you can install the Arbiter on a Windows virtual machine in one data center that arbitrates the hosts in the other data center and vice versa.

Figure 5 is an example. Do not recover the Arbiter storage device to a previous point in time with a snapshot or backup and restore process or you could corrupt the virtual machine data.

Do not install Arbiter on a virtual machine managed within the same cluster it serves. If you do install the Arbiter in this configuration, data unavailability can occur.

Never restart the Arbiter for any reason other than resolving problems. Your federation cannot communicate properly when the Arbiter is not running. You can upgrade an arbiter or move it to another location only when hosts in the federation are healthy. If the federation is not healthy quorum is lost do not upgrade or move the arbiter.

You cannot use a single switch. You can only deploy hosts using Aruba switches to a cluster that does not contain previously deployed HPE OmniStack hosts. These interfaces come disabled by default. Enable the switch management interface and configure it as needed. Ensure that LLDP is enabled. Create a user account with administrator privileges to use during deployment when prompted by deployment manager. It is recommended that you not change this range. This streamlines the ability to monitor the platform, adapter layout, network settings, BIOS settings, firmware, and networks in your data center.

Is this a Linux or Windows guest? Found something interesting though, in Ubuntu If I do the same with Could explain why I was having issues after even setting the buffers on my Hi Mike, I have some questions, we already tried above ring size configuration in our guest operating systems which are win10 and Win7 machines but unfortunately performance test has same result of packet loss. Hi Shams — how much packet loss are we talking about? Small amounts are certainly not unusual for busy VMs.

Also, where are you seeing the packet loss? Hi Mike, Thanks for your prompt reply! Packet loss is We are seeing the packet loss from the ESXi host prospective and above results are esxtop but not in-guest statistics. Hey Mike — we saw something similar in our environment but it was actually due to ESXi buffer overrun. Over a day.

Increasing buffer and turning on RSS solved our issue. Just tossing some additional experience out there in case anyone google-foos their way to an answer. Thanks for the info, Matt! The symptoms from the perspective of the guests are pretty much the same — packet loss and retransmissions. Thanks for sharing. You run vsish against the physical nics hence the pnic in the path.

Hi Ste — You can use the vsish path that Matt mentions above. Exactly as described in the blog. The jumbo frames your were seeing should be a result of the LRO large receive offload capability in the vmxnet3 driver. Mike -This is an excellent article that it still quite valuable today.

I have a similar situation where the second ring is filling but we do not have jumbo frames enabled anywhere. If burst queuing is enabled it allows vNic RX Ring to overflow to this burst queue to avoid packet drops. You are commenting using your WordPress. You are commenting using your Twitter account.

Rx Buffering Not unlike physical network cards and switches, virtual NICs must have buffers to temporarily store incoming network frames for processing. A Lab Example To demonstrate ring exhaustion in my lab, I had to get a bit creative.

Checking Buffer Statistics from ESXi Most Linux distros provide some good driver statistic information, but that may not always be the case. Share this: Twitter Facebook. Mike, Have you ever seen this: fail to map a rx buffer The buffers on the guest are set to their max, but I have never seen this before. Thanks in advance! Regards Shams. How did you identify the UCS overrun. At what level and how did you diagnose the issue. Leave a Reply Cancel reply Enter your comment here Fill in your details below or click an icon to log in:.
