The HPE SimpliVity OmniStack Interoperability Guide is a document that provides the information about the supported hardware and software components for the HPE SimpliVity solution, such as the HPE SimpliVity nodes, the VMware ESXi hosts, the VMware vCenter Server, the HPE OmniStack software, the HPE SimpliVity Arbiter, and the guestoperating systems1. The guide also provides the compatibility matrix and the configuration guidelines for the HPE SimpliVity solution. The ESXi version (option B) and the guest OS version (option C) are two items that can be found in the HPE SimpliVity OmniStack Interoperability Guide, as they are essential for the proper functioning and performance of the HPE SimpliVity solution. The guide lists the supported ESXi versions for each HPE SimpliVity node model and HPE OmniStack software version, as well as the supported guest OS versions for each HPE SimpliVity node model1. The GPU accelerators (option A), the vSphere license (option D), and the processor model (option E) are not items that can be found in the HPE SimpliVity OmniStack Interoperability Guide, as they are not relevant or required for the HPE SimpliVity solution. The GPU accelerators are not supported by the HPE SimpliVity solution, as they are not compatible with the HPE SimpliVity nodes2. The vSphere license is not specified by the HPE SimpliVity solution, as it depends on the customer’s choice and needs3. The processor model is not listed by the HPE SimpliVity solution, as it is already determined by the HPE SimpliVity node model4. References:

HPE SimpliVity is a hyperconverged infrastructure solution that combines compute, storage, networking, and data services in a single platform. HPE SimpliVity integrates with HPE StoreOnce, a disk-based backup appliance, to provide efficient and reliable data protection and disaster recovery for distributed edge sites12.

HPE SimpliVity uses HPE StoreOnce Catalyst, a deduplication protocol, to replicate data from HPE SimpliVity clusters to HPE StoreOnce appliances. HPE SimpliVity leverages its global deduplication and compression capabilities to send only the unique data blocks to HPE StoreOnce, reducing the bandwidth and storage requirements34.

To optimize the replication performance, the design aspects that need to be evaluated are the number of the HPE SimpliVity clusters and Catalyst stores used. According to the HPE SimpliVity with HPE StoreOnce Reference Architecture document, the following best practices are recommended:

Use one Catalyst store per HPE SimpliVity cluster. This simplifies the configuration and management, and avoids potential performance issues due to contention or fragmentation.

Use one Catalyst store per HPE StoreOnce appliance. This ensures optimal deduplication ratios and avoids unnecessary data movement across appliances.

Use one HPE StoreOnce appliance per HPE SimpliVity federation. This minimizes the network hops and latency, and maximizes the throughput and efficiency.

Use dedicated network interfaces and VLANs for the replication traffic. This isolates the replication traffic from the production traffic, and provides better security and performance.

The other options are not relevant for optimizing the replication performance. The performance optimization features provided by VMFS datastores compared to NFS datastores are not applicable for HPE SimpliVity, as it uses its own file system and data virtualization platform. The intelligent workload optimizer settings are not related to the replication performance, but to the VM placement and load balancing within the HPE SimpliVity cluster. The HPE SimpliVity model used does not affect the replication performance, as long as it meets the minimum requirements for the HPE StoreOnce integration.

HPE SimpliVity RapidDR is a disaster recovery orchestration tool that automates and simplifies the recovery process of VMs protected by HPE SimpliVity backups. It can be used in the event of disaster to efficiently restore VMs across the primary and secondary sites, which consist of multiple HPE SimpliVity nodes12.

HPE SimpliVity RapidDR requires VMware vCenter Server, a centralized management platform for VMware vSphere environments, to perform the recovery operations. VMware vCenter Server is licensed per instance, which means that each vCenter Server installation requires a separate license3 .

To reduce the vCenter Server license cost, a customer can use only a single vCenter Server instance to manage the HPE SimpliVity federation, which is a group of HPE SimpliVity clusters that share the same configuration and policies. This deployment scenario is possible when the federation is managed centrally, which means that all the HPE SimpliVity nodes are registered to the same vCenter Server instance, regardless of their physical location .

The other options are not valid for reducing the vCenter Server license cost. The number of VMs covered by a single recovery plan does not affect the vCenter Server license requirement, as long as the VMs are managed by the same vCenter Server instance. Enabling Enhanced Linked Mode for vCenter allows multiple vCenter Server instances to share information and provide a single pane of glass view, but it does not eliminate the need for separate licenses for each vCenter Server instance. Disabling Intelligent Workload Optimizer, a feature that balances the VM workload across the HPE SimpliVity cluster, has no impact on the vCenter Server license requirement.

Hyper Protected is one of the four pillars of HPE SimpliVity’s value proposition, along with Hyper Simple, Hyper Efficient, and Hyper Manageable. Hyper Protected refers to the ability of HPE SimpliVity to provide built-in data protection and disaster recovery for virtual machines (VMs) with unprecedented speed and efficiency. HPE SimpliVity can backup or restore 1TB VM in less than 1 minute, thanks to its unique data architecture that deduplicates, compresses, and optimizes data at inception, and its global federated management that enables policy-based automation across multiple sites. Restoring individual files from a VM backup, defining a storage policy using RAID 6 or RAID 60 to protect the VM, and integrating with Veeam to provide an external backup solution are not specific to HPE SimpliVity’s Hyper Protected capability, and can be done by other solutions as well. References: Using HPE SimpliVity Official Certification Study Guide, page 11, section 1.2. SimpliVity Hyperconverged, section “Hyper Protected”. HPE SimpliVity 380 Gen10 Node, section “Features”. SimpliVity HyperGuarantee, section “Remain online and recoverable — always”.

According to the HPE SimpliVity documents and learning resources, each datastore in an HPE SimpliVity cluster is presented to the HPE SimpliVity nodes as a VMFS datastore. A VMFS datastore is a VMware-specific file system that allows multiple ESXi hosts to access the same storage device concurrently. HPE SimpliVity uses VMFS datastores to store virtual machine files and provide shared storage to all virtual machines on the hosts. HPE SimpliVity does not use vSAN, NFS, or vVol as the datastore type. References: Using HPE SimpliVity Official Certification Study Guide, page 41; SimpliVity Video - How to Create a HPE SimpliVity Datastore

You can apply a backup policy at the datastore level, as this is the level at which HPE SimpliVity manages the virtual machines and their backups1. A backup policy consists of one or more rules that specify the destination, frequency, and retention of the backups. You can assign a backup policy to a datastore, and all the virtual machines in that datastore will inherit the backup policy. You can also override the backup policy for individual virtual machines, if needed2. Applying a backup policy at the cluster level (option A), the datacenter level (option B), or the vCenter Server level (option C) is not possible, as these are not the levels at which HPE SimpliVity manages the virtual machines and their backups. These levels are used for organizing and managing the ESXi hosts and the HPE SimpliVity nodes, but not for applying backup policies. References:

The best way to migrate virtual machines from the existing infrastructure to HPE SimpliVity is to share HPE SimpliVity datastores with standard ESXi hosts, and migrate the virtual machines using VMware vSphere® Storage vMotion®1. This method allows the virtual machines to be moved to the HPE SimpliVity datastores without any downtime or impact on the performance. The HPE SimpliVity datastores are automatically created and managed by the HPE SimpliVity Virtual Controller, and they can be shared with any ESXi host that is in the same vCenter Server® as the HPE SimpliVity cluster2. Connecting VMFS datastores holding the virtual machine files to HPE SimpliVity nodes, and migrating the virtual machines (option A) is not a supported method, as the HPE SimpliVity nodes do not have direct access to the VMFS datastores, and they can only use the HPE SimpliVity datastores3. Mapping VMFS datastores holding the virtual machine files as an RDM to HPE SimpliVity nodes, and migrating the virtual machines (option C) is not a supported method, as the HPE SimpliVity nodes do not support RDM devices, and they can only use the HPE SimpliVity datastores4. Adding ESXi system to the HPE SimpliVity cluster, and migrating the virtual machines to HPE SimpliVity datastores (option D) is not a recommended method, as it requires the ESXi system to be converted to an HPE SimpliVity node, which involves installing the HPE OmniStack software and the HPE SimpliVity Virtual Controller, and reconfiguring the network settings. This method may cause downtime and data loss, and it is only advised for specific scenarios, such as replacing a failed node or expanding the cluster. References:

Register External Store …1

This option allows you to register an HPE StoreOnce Catalyst Store as an external backup target for HPE SimpliVity. This enables you to store VM backups on an HPEStoreOnce system, which is a disk-based backup solution that offers deduplication, compression, encryption, remote replication, and direct application-managed integration2.

To use this option, you need to have an HPE StoreOnce appliance connected to your HPE SimpliVity cluster, and configure a Catalyst Store on it. Then, you can select the All HPE SimpliVity Actions menu, and click Register External Store. You will be prompted to enter the following information:

The name of the external store

The IP address or hostname of the HPE StoreOnce appliance

The name of the Catalyst Store

The credentials of the Catalyst Store

After you enter the required information, click OK to register the external store1.
