The VxFlex OS SDC on each host exposes a Protocol Endpoint (PE) for each VASA provider.A VxFlex OS cluster may contain a single VASA provider or three for a highly resilient configuration using replica sets.VMware APIs for Storage Awareness (VASA) VxFlex OS 3.0.1 and later supports VMware vVols 1.0 through VASA 2.0 implementation. The VMware features are supported by VxFlex OS: VxFlex OS implementation in ESXi with SDC in VMkernelĪnother figure for VxFlex OS implementation on ESXi The SDC is installed inside the ESXi kernel and can be installed like any other VIB. These LUNs can be formatted with VMFS and then exposed using the ESXi host to the virtual machine or can be used as RDM devices. The logical adapter informs the ESXi about the arrival and disappearance of SCSI devices. The SDC creates a logical adapter, which is an ESXi kernel construct.

Storage Data Client (SDC): A lightweight device driver exposes VxFlex OS volumes as block devices to the application on the same server on which the SDC is installed. The SDS is installed on all servers contributing storage devices to the VxFlex OS system. Storage Data Server (SDS): The SDS manages the capacity of a single server and acts as a back-end for data access. In ScaleIO 2.0 and VxFlex OS 2.6, there is an additional option of configuring the MDM as a five-node cluster (Primary MDM, 2 Secondary MDMs, and 2 Tie-Breaker MDMs) to provide greater resiliency.
In ScaleIO 1.32 the MDM is configured as a three-node cluster (Primary MDM, Secondary MDM, and Tie-Breaker MDM). The MDM is configured in redundant Cluster Mode.
Meta Data Manager (MDM): The MDM configures and monitors the ScaleIO system.
#Vsphere client 6.5 add storage to node software
Storage Virtual Machine (SVM): The SVM is a Linux-based virtual machine that is dedicated to VxFlex OS and is used to host the different VxFlex OS software components described here.
The VxFlex OS hyperconverged configuration consists of a dedicated Storage Virtual Machine (SVM) and three software components: Implementation requires one Gbps network.Implementation requires three ESXi servers with 100 GB of free capacity per server.These are the minimum system requirements for a VxFlex OS implementation: Its scale-out server SAN architecture can grow from a few to thousands of servers. VxFlex OS is elastic and delivers linearly scalable performance. Dell EMC VxFlex OS is a software-based storage area network (SAN) that converges storage and compute resources to form a hyperconverged, enterprise-grade storage product.
