Architecture Overview
The main requirements for a SAP HANA solution are defined by SAP. The hardware partner has only limited
possibilities for altering the infrastructure design.
SAP has defined the following requirements:
●
Intel
®
Xeon
®
processor E7-8880 v3 CPU
● 512 GB per CPU socket for analytics (768 GB for SAP S4/HANA)
●
10 Gigabit Ethernet redundant storage connectivity to network-attached storage (NAS)
● 8-Gbps (or greater) Fibre Channel redundant storage connectivity to SAN
●
10 Gigabit Ethernet redundant SAP HANA connectivity between SAP HANA nodes
● 1 and 10 Gigabit Ethernet redundant uplink
●
SUSE Linux Enterprise Server for SAP applications 11 SP3, 4, and 12 (soon SP1 as well)
● RHEL Server for SAP HANA 6.7 (soon 7.0 as well)
The architecture also includes the following components:
●
Solution management components (optional)
◦
Cisco 2911 Integrated Services Router (ISR; optional)
●
Connectivity components (optional)
◦
Cisco Nexus 2000 Series for Small Computer System Interface over IP (iSCSI) boot
◦
Cisco Nexus 9000 Series for internal and external communication
◦
Cisco MDS 9000 Family SAN connectivity
●
Computing components
◦
Cisco C880 M4 Server
◦
4 x 16-Gbps Fibre Channel
◦
8 x 10 Gigabit Ethernet
◦
4 x 1 Gigabit Ethernet
● Storage components
◦
This document describes how to use existing customer storage to connect the Cisco C880 M4 to it.
Recommended Network Layout
Figure 1 shows a possible network configuration for an SAP Business Warehouse (BW) on SAP HANA system
running on four hosts (one master, two workers, and one standby) that are connected through an internode
network (red). Two types of clients are attached: SAP BW application servers (light blue) and other SAP HANA
clients (dark blue; for example, SAP HANA Studio). The data is persistently stored on enterprise storage (purple)
and backed up to a separate storage location (green). To make this setup highly available, a standby host has
been defined; moreover, the data is replicated to another data center using SAP HANA system replication (yellow).
In addition, external administration tools can be used because a separate, low-bandwidth administrative network
(black) is configured.
