• Allow OS agnostic monitoring

Support SAP HANA takeover

• Use NSX to support automate SAP HANA takeover

• Secure Application and DBMS communication E2E

SAP HANA Try'n'Buy

• Try SAP HANA provisioned by on of VMware's 4000+ vCAN partners

• Migrate VMs online into local DC upon purchase decision

Outlook:vMotion of NVM

• Upcoming NVM technology re-enforces decentralized data storage (on hosts)

• VMware will be uniquely positioned to preserve workload mobility through VMware vMotion

SAP HANA Sizing Considerations

• The purpose of SAP HANA validation efforts between SAP and VMware is to ensure sizing considerations remains valid. By applying configuration Best Practices performance deviations to bare metal baseline are limited, so sizing can be approached as it would be a usual (non virtualized) environment.

• A usual SAP HANA system sizing starts with (1) the sizing of the SAP application. With the output of this task the SAP HANA HW Partner can then provide (2) a suitable and certified SAP HANA server. Last, (3) the actual VM can be fitted to the needs of the SAP HANA application.

• As virtualization allows for a higher degree of freedom in configuration than SAP HANA HW appliances do, it’s of assents that the vAdmin ensures his VM configuration is made in respect to

• Required resource reservations & sizing recommendations

• SAP HANA core-to-memory ratios

• Underlying NUMA topology

“sizing can be approached as it would be a usual (non virtualized) environment.”

Excurse: Non Uniform Memory Access (NUMA) Fundamentals

• Each socket has its own memory controller (IMC)

• While this scales well, memory access is non-uniform:

– local vs. remote access comes with NUMA-effects

• Since SPS 09, SAP HANA targets NUMA-aware thread scheduling & data placement

– Assign memory objects to sockets

– Threads bound to specific socket

– Strategy for data placement to socket & complex query execution plans

Dos and Don’ts for Running SAP HANA virtual

CPU resource reservation

•While as vAdmin used to GHz as a metric for CPU consumption, SAP documentation focuses on vCPUs instead. Avoiding over commitment hence refers to the number of committed vCPUs and will be ensured by corresponding CPU resource reservation.

•Unless the host is fully utilized, CPU resource reservations does not have any impact on actual performance.

CPU affinity

•To remain in control of vCPU to physical resource mappings, SAP strongly recommends to use CPU affinity rules to assign vCPUs to cores.

•While affinity rules will vMotion (transfer) with a VM to a different host, such rules may prevent successful startup of a VM e.g. in case of a HA event.

NUMA topology

•Taking NUMA topology into account, wrong virtual to physical mappings may lead to serious performance impacts. The VM CPU configuration (cores per socket) should hence always respect underlying physical topology.

• inhomogeneous environments requires virtual topology to reflect the smaller (older) CPU to still allow e.g. vMotion.

preferHT=on|off

•The use of Intel’s Hyper-Threading technology enables for another +/- 20% of SAP HANA performance. That’s why by default HT shall be enabled on host and VM level (NUMA.preferHT=1). Note that in this case you need to configure twice the amount of vCPUs than physical cores expressed in SAP sizing.

• If constraint by max vCPU limit you may consider to set NUMA.preferHT=0 to provide more processing power to a particular VM, in disadvantage of other VMs running on same host (See also SAP Note 2003582).

CPU Best Practices



bution

Dos and Don'ts for Running SAP HANA Virtual

• In case of SAP, the following parameters shall be set (See SAP Note 1409604):

– on the guest VM level: Tools.GuestLib.EnableHostInfo = true

– on the host level: Misc.GuestLibAllowHostInfo = 1

• It’s further recommended, to configure remote access through SAP router to ease support:

– Connections needs to be maintained on SAP Service Market Place (SMP). In addition, the SAP Router configuration needs to be adjusted to allow relevant IPs/Logical Hosts and Ports to be opened. A by default read-only user must be provided.

– Examples of usefully connections related to VMware:

• Connection name: “VMware: vSphere Web Client [instance description]” URL is usually: https://<vCenter Host>:9443/vsphere-client

• Connection name “VMware: vRealize Operations Manager [instance description]”

Dos and Don'ts for Running SAP HANA Virtual

• Ensure that vCPU hotplug is deactivated on hypervisor level, as otherwise vNUMA will get disabled (VMware KB 2040375). Note, that as of today SAP HANA does not support CPU hotplug functionality in general.

• VMware strongly recommends to set sched.cpu.latencySensitivity = normal to avoid negative effects on application level, including disconnects during vMotion actions. (SAP Note 2015392).

• Set Linux kernel parameter elevator = noop to disables I/O scheduling, as ESXi has its own I/O scheduling mechanisms and scheduling I/O inside the Guest OS may cause unnecessary overhead (Red Hat KB 5428 / SUSE KB 7009616)

• Disable Transparent Huge Pages (THP), as THP is not supported for the use with SAP HANA and may lead to hanging situations, as well as performance degradations

• VMware recommends using Open VMware Tools (OVT) redistributed by operating system vendors (VMware KB 2073803).

SAP HANA on VMware vSphere Support Roadmap

#VIRT1138BE CONFIDENTIAL28

When will my scenario be supported ?

• Will it take as long as last time till support is granted?

• Why does it always take so long?

• May a different platform provide the better options?



bution

Rethink Your Point of View

Built-in HA

•Far before SAP HANA has even thought about their auto host-standby solution, VMware HA had already proven 99,9% availability

Proven multi-tendency

•When MDC had been still part of SAP HANAs vision, multi-VM support for multiple prod. SAP HANA VMs had been real since late 2013

HA/DR Automation

•The day SAP announced SAP LaMa handling now SAP HANA takeover, VMware NSX (with similar capabilities) had been already long time in the market

Workload Management

•With VASA 2.0 VMware allows to define min/max IO performance on VM level (aka storage IO control). When will MDC have it?

Hyper Converged

•VMware vSAN is the leading technology in the HCI space and had already proven to provide necessary performance to also work with SAP HANA

SAP HANA on VMware vSphere Support Roadmap

Scale-out / 8-sockets / 6TBSkylake / vSphere [next]

CloudOS / Cross Cloud

• SAP and VMware will continue their close collaboration to ensure support of future versions for SAP HANA and VMware vSphere, as well as constantly pushing for new scenarios to be added to the list of supported scenarios

• Goal is to allow even more options and deployment flexibility for VMware virtualized SAP HANA systems
