Storage requirements

From Genesys Documentation
Jump to: navigation, search

Provides information about different storage types required for Genesys Multicloud CX services.

Deciding storage includes a lot of factors such as the number of agents, call volumes, call recordings and archiving them, data security, accessibility, and so on. It also includes technical factors such as the Input Output Per Second (IOPS) or throughput, storage type, latency, and so on.

In Genesys Multicloud CX private edition, you will create storage for specific services, for example, Genesys Customer Experience Insights (GCXI), and Voice. The services that require storage elements, such as file and disk storage for processing its data, use the Kubernetes Persistence Volume subsystem (PV). The storage subsystem and Kubernetes StorageClass types requirements for different services for different Kubernetes platforms are given in the following tables:

You can create or select the storage subsystem for your service on a specific Kubernetes platform based on the information presented in the corresponding table. For the exact sizing of each storage subsystem or PVs, refer to the related service-level documentation.

Important
By default, the Kubernetes platform creates default file and disk storage classes. However, Genesys recommends not to use them but to create a custom file and disk storage for your service.
Tip
You can determine the storage requirements for your contact center yourself by either exploring the storage requirements of each service, by using the Sizing Calculator or by leveraging the Genesys Professional Services team's support.

File and disk storage for AKS

The following table provides the storage information for AKS:

AKS Storage Class Name# Storage Type Notes Associated Services
disk-hdd (ephemeral) Standard_HDD Node disk mounted via HostPath.

disk-standard

disk-premium

Azure Disk - Standard

Azure Disk - Premium

Use single AZ disks to create an RWO volume that can be attached to a single pod.

  • GVP
  • GWS
  • UCSX
files-standard Azure Files - Standard Fileshare LRS Local redundant storage (LRS) for RWX volumes that can be shared between multiple pod instances; replicated data in a single AZ.

Lower throughput than premium and no IOPs guaranteed.

BDS
files-standard-redundant Azure Files - Premium Fileshare ZRS Zonal redundant storage (ZRS) for RWX volumes shared across multiple pods; replicated data across multiple AZs in a region.

No IOPS guaranteed - similar to NFS.

  • #The GKE storage class names are created by default. You can modify the storage class names based on your organizational needs.
  • *RWO type storage is tested with the default CSI driver.
  • **RWX type storage is tested with the Filestore CSI driver. This storage driver is not enabled by default and it must be enabled in the GKE clusters. However, this configuration is available only in GKE 1.21.x releases. For more information on enabling Filestore CSI driver, see GKE documentation

File and disk storage for OpenShift

The following table provides the storage information for OpenShift:

Storage Type Description Associated Services
Disk Uses dynamically provisioned disks (which reside in a single AZ) to create an RWO volume that can be attached to a single pod. Genesys recommends SSD storage for production deployments.
  • GCXI*
  • GVP
  • Gplus-WFM
  • Interaction Server*
  • Pulse*
  • Tenant*
  • Voice Services*
  • WebRTC*
Files-local Create an RWX volume that can be attached to many pods across all the node pool AZs; this is similar to NFS. The local type means 'Locally Redundant Storage' that replicates copies of data in a single AZ in a single region. Hence, there is a risk of your Persistent Volume Claims (PVCs) becoming unavailable if a single region completely fails. It needs a guaranteed 1 IOPS per GB stored with a minimum of 100 IOPS while allowing bursting and higher throughput than standard HDD storage. Genesys recommends SSD storage for production deployments. Note: The minimum volume size needed is 100GB. BDS
Files-redundant Create an RWX volume that can be attached to many pods across all the node pool AZs. The redundant type means 'Zonal Redundant Storage' that replicates copies of data across multiple AZs in a region. No IOPS guarantee is needed. Similar to NFS.

Object storage Create object storage which is optimized for storing massive amounts of unstructured data across AZ and regions. Similar to S3 or Azure Blob, Google Cloud Storage.

*Genesys Multicloud CX services that use the disk space mainly for logging purposes. You can optionally configure them not to use the disk space. Refer to the related service-level guides for more information.
