Google Cloud has established the following requirements to be met for a storage partner's system to achieve Anthos Ready qualification. Container Storage Interface (CSI) is a vendor independent standard for vendors to expose their block and file storage systems to Container Orchestration Systems
(COs) like Kubernetes. Anthos Ready storage qualification ensures that our storage partners' CSI drivers can provide a seamless experience between Anthos on-prem (on VMware or bare metal)
and the partners' block/file storage systems.
For a partner's CSI driver to be considered for the program, the partner must support the following:
Ability to deploy the storage CSI driver and its dependencies, using the Kubernetes framework
Core functions that customers require today, including dynamic provisioning of volumes, by using the Kubernetes native storage APIs
The ability to manage storage for Kubernetes scale up and scale down scenarios
Workload portability with persistence storage for the stateful workloads
For Anthos clusters on VMware qualifications, storage partners are given the option of which version of vSphere to perform their qualification with. If you do not see a specific version of vSphere included in the qualification matrix for a given partner, check with the partner to confirm their support.
For Anthos clusters on bare metal qualifications, storage partners performed the qualifications on one or more operating systems based on their support of the OS. If you do not see a specific OS or version, check with the partner to confirm support.
Container Storage Interface (CSI) specification was designed to provide an interface that Container Orchestrators (like Kubernetes) can use to provision storage. Storage vendors implement CSI Drivers that conform to the specification which provide storage services via this vendor neutral Container Storage Interface.
The PowerScale CSI Driver by Dell EMC implements the standardized interface (CSI spec) between enabled Container Orchestrator (CO) and Dell EMC PowerScale(formerly Isilon) Storage Arrays. It is a plug-in that is installed into Kubernetes to provide persistent storage using Dell storage systems. The CSI driver for PowerScale offers several enterprise grade features including, but not limited to the following: static provisioning, dynamic provisioning, creation & deletion of volume snapshots, volume cleaning, and so forth.
Hitachi Storage Plug-in for Containers (HSPC) provides connectivity between Docker, Kubernetes, or Kubernetes CSI containers and Hitachi Virtual Storage Platform (VSP) E series, F series, and G series enterprise-class hybrid and all-flash storage systems.
HSPC is a software component that contains libraries, settings, and commands that you can use to create a container in order to run your stateful applications. It enables the stateful applications to persist and maintain data after the life cycle of the container has ended. Storage Plug-in for Containers provides persistent volumes from Hitachi VSP series storage, utilizes built-in high-availability and orchestrates storage tasks between hosts in a cluster.
A Container Storage Interface (CSI) Driver for Kubernetes. The HPE CSI Driver for Kubernetes allows you to use a Container Storage Provider to perform data management operations on storage resources. The HPE CSI Driver allows any vendor or project to develop its own Container Storage Provider by using the CSP specification available on the HPE DEV portal. This makes it very easy for 3rd parties to integrate their storage solution into Kubernetes as all of the intricacies are taken care of by the HPE CSI Driver.
The CSI specification includes constructs to manage snapshots (not yet supported in Anthos) as native Kubernetes objects and create new PVCs by referencing those objects.
Trident has been validated with SolidFire and ONTAP solution using SAN and NAS protocols.
The Container Storage Interface (CSI) provides a framework to standardize communications between container orchestrators and storage systems. This is a community effort driven by the Cloud Native Computing Foundation (CNCF) Storage Special Interest Group (SIG). NetApp implemented CSI in Trident to simplify the consumption of persistent storage for Kubernetes users while offering a universal interface to all major NetApp storage platforms. CSI is supported by Trident versions 19.07 or above and it can be downloaded from netapp.io.
The Portworx Enterprise Storage Platform for Kubernetes is built from the ground up to solve the business requirements necessary to run data-rich applications on Kubernetes in production. The Portworx Enterprise platform provides solutions for scalable, performant container storage, Kubernetes backup and disaster recovery, multi-cloud operations, data security, capacity management, and compliance and governance.
ROBIN Cloud Native Storage is an application-aware container storage that offers advanced data management capabilities and runs natively on any Kubernetes distribution including Google Kubernetes Engine (GKE) and Anthos. ROBIN Cloud Native Storage delivers bare-metal performance and enables you to Protect (via Snapshots, Backups), Secure (via encryption), Collaborate (via Clones and git like push/pull workflows), and make Portable (via Cloud-sync) any Stateful application that is deployed using Helm Charts or Operators.
*VMware vSphere CSI pre-installed with Anthos is generally available as of Anthos version 1.7.x. For VM configuration requirements, see the VMware prerequisites documentation.
The VMware vSphere Container Storage Interface (CSI) is an out-of-tree plug-in that exposes vSphere storage to containerized workloads on Kubernetes. The plug-in enables VMware vSAN and other types of vSphere storage. It communicates with the Cloud Native Storage (CNS) control plane on VMware vCenter Server for all storage provisioning operations.
