Specifically, it will detail the components of the solution and high-level configuration of each component in the design. This solution is considered to be an additional component and extension of the vCenter Server solution offering on IBM Cloud. As a result, this document will not cover the existing configuration of the foundation solution on IBM Cloud. Therefore, it is highly recommended to review and understand the VMware on IBM Cloud solution architecture located on the IBM Architecture Center before reading this document. Figure 1 VMware vCenter Server on IBM Cloud 1.2 Key Benefits NetApp ONTAP Select is a software–only version of NetApp ONTAP, providing software–defined storage (SDS) capabilities. ONTAP Select virtualizes the local storage on VMware vSphere hosts, providing enterprise class storage management. While IBM Cloud provides several file, block, and object storage offerings, many of these are shared infrastructure. NetApp ONTAP Select on IBM Cloud hosts your storage on dedicated infrastructure and provides familiar NetApp capabilities, including: • Dedicated highly available clustered NFS, CIFS, and iSCSI storage • NetApp SnapMirror, SnapVault, FlexClone, and SnapRestore • Deduplication and compression Not all NetApp ONTAP features are supported by ONTAP Select. Copyright IBM Corporation 2017 Page 4 of 12 2 Design 2.1 Overview The NetApp ONTAP Select solution complements the VMware vCenter Server on IBM Cloud offering by providing storage virtualization services. NetApp ONTAP Select runs within a VMware cluster and virtualizes the local storage on the vSphere hosts. NetApp supports a collocated deployment model, where ONTAP Select coexists in the same cluster as other workloads. However, this design deploys NetApp ONTAP Select using the recommended dedicated model, where other workloads are not expected to share the same cluster as ONTAP Select. As a result, this design sizes the hardware configuration only based on the requirements for ONTAP Select. Figure 2 NetApp ONTAP Select on VMware vCenter Server High Level Components The storage provided by your NetApp ONTAP Select instance can be used by other VMware vCenter Server instances, VMware Cloud Foundation instances, or other infrastructure deployed in your IBM Cloud account such as virtual server instances (VSIs) or bare metal servers running various operating systems or hypervisors. You can attach the NetApp ONTAP Select storage using NFS, CIFS, and iSCSI protocols. Figure 3 illustrates the components of the ONTAP Select deployment, including an ONTAP Select deployment VM that deploys the cluster, and four ONTAP Select cluster VMs, one per host. Copyright IBM Corporation 2017 Page 5 of 12 Figure 3 NetApp ONTAP Select deployment 2.2 Physical Infrastructure This design notes the differences between the NetApp ONTAP Select architecture and the VMware vCenter Server solution architecture on which this architecture depends. Physical Host Design This design varies the physical compute configuration. The host CPU and memory requirements are reduced because the solution is sized only for NetApp use. The host disk requirements are increased because the solution requires local storage in each host for ONTAP Select’s storage virtualization. This solution is deployed using exactly four hosts; no additional hosts will be added to the cluster after deployment. The physical host hardware comprises a 4U chassis with the following possible configurations: Option CPU Memory Network ONTAP drives High performance Dual Intel Xeon E5-2650 128 GB 4 x 10 Gbps uplinks Up to 22 drives v4, 24 cores total High capacity Dual Intel Xeon E5-2650 64 GB 4 x 10 Gbps uplinks Up to 34 drives v4, 24 cores total Table 1 Physical host configurations and options NetApp ONTAP Select is available in both Standard and Premium deployments. The Premium deployment and licensing utilizes virtual machines with 64GB memory, and is required when using SSD storage, but optional when using SATA drives. The Standard deployment and licensing utilizes virtual machines with 16GB memory, and is the normal choice when using SATA drives. This architecture specifies the use of the Standard deployment for the high capacity SATA configuration. Physical Storage Design This design uses two 1TB SATA disks in a RAID–1 configuration for local hypervisor storage as specified in the vCenter Server solution architecture. Additional disks are added to the hosts for use by NetApp ONTAP Select according to the choice of configuration: Copyright IBM Corporation 2017 Page 6 of 12 Option Disks RAID configuration High performance Options RAID 5, 1 group with
