What is MetroCluster in NetApp?

MetroCluster allows for synchronous mirroring of volumes between two storage controllers providing storage high availability and disaster recovery. A MetroCluster configuration consists of two NetApp FAS controllers, each residing in the same datacenter or two different physical locations, clustered together.

How MetroCluster works?

In the event of a building failure, NetApp MetroCluster gives us redundancy by combining High Availability and SyncMirror. SyncMirror is used to mirror the aggregates to a disk shelf in each building. We can selectively choose which aggregates to mirror.

What is NetApp OnCommand?

OnCommand Insight enables you to simplify operational management of complex private and hybrid cloud and virtual IT environments. Insight is a single solution to enable cross-domain, multi-vendor resource management and analysis across networks, storage, and servers in physical and virtual environments.

Is netapp MetroCluster active active?

MetroCluster is an array-based, active-active clustered solution that eliminates the need for complex failover scripts, server reboots, or application restarts.

What is Nvram mirroring?

The nonvolatile memory (NVRAM or NVMEM, depending on the platform model) in the storage controllers is mirrored both locally to a local HA partner and remotely to a remote DR partner on the partner site. In the event of local failover or switchover, this ensures that data in the hardware cache is preserved.

How do I access NetApp OnCommand system manager?

Accessing OnCommand System Manager from the Unified Manager interface

  1. In the left navigation pane, click Dashboards > Cluster View.
  2. In the Dashboards/Cluster View page, select the cluster that you want to manage.
  3. Click the System Manager icon.
  4. Log in to System Manager by using your cluster administrator credentials.

What is a MetroCluster?

A MetroCluster is essentially a stretched mirrored HA pair of storage nodes in a cluster configuration. This stretched cluster can be implemented with two nodes within a maximum of 160kms of each other.

What is Metro storage cluster in VMware HA?

VMware vSphere Metro Storage Cluster (vMSC) is a feature that extends VMware HA with active-active stretched storage. VMware HA, as stated in the previous section, requires shared storage to be presented to all hosts in a cluster to enable restart of virtual machines in the event of a disaster.

How many nodes can a MetroCluster have?

This stretched cluster can be implemented with two nodes within a maximum of 160kms of each other. There are two types of MetroCluster, a stretched MetroCluster which can have two nodes within 500 metres of each other and a Fabric-attached MetroCluster which can be greater than 500 metres and less that 160kms.

What is NetApp MetroCluster?

NetApp MetroCluster NetApp ® MetroCluster ™ configurations combine array-based clustering with synchronous replication to deliver continuous availability, immediately duplicating all of your mission-critical data on a transaction-by-transaction basis.
