 Scale up is supported up to a
configuration with Four (4)
B460 Boards – this yields
133,000 SAPs. This is a large
amount of non-HANA database
capacity.
 If you need more than 133,000
SAPs on the database server
and hence need to scale out
across blades, a product like
Oracle RAC or DB2 PureScale
is required.
SAP and HANA on VCE – Scale and Sizing Drivers
Non-
HANAHANA
 Scale up is supported up to 2TB for
Suite on HANA and up to 1TB for BW
on HANA
 Non-Virtualized Scale out is
supported up to 5TB for Suite on
HANA and up to 10TB for BW on
HANA.
 Scale out currently only works with
the 512GB blades.
 VCE is working on completing
certification for both the 1TB and
2TB blades and expects to receive this
within the next 60 days. This will
increase the maximum size of the scale
out model.
 The rule for the relationship of disk to
HANA instance is that for each 2TB of
HANA, you can have a maximum of
forty-eight (48) 600GB 15K drives.
 Due to this limitation the VMAX 10K
has a maximum capacity of 960
physical disk drives (~227TB
useable).

What did we learn?
…in the review of the SAP BOM. Regional Sales teams and even vendor
solution architects do not always have the knowledge of the necessary
adjustments to out of the box VCE IaaS configuration required for SAP TDI.
…Make sure it’s well marked as an SAP TDI solution! Make sure
that the necessary adjustments to front end cabling and back end LUN
masking required for TDI certification are indicated in the LCS form.
…for Suse in view of your high availability and DR replication
design, on both HANA and non-HANA instances..
…to overcome some of the limits around HANA on Vsphere. Stay current
on the announcements, and close to the experts that can help you utilize
VMware tools around high availability, capacity planning, and operations
management to actively manage and contain you SAP landscape components.

Overview of SAP HANA on VMware Vsphere 5.5
 At present, SAP has only certified HANA to be
virtualized on VMware’s hypervisor.
 This certification is for both non-production and
production implementations of HANA.
On
 Compute used for the ESX farm must be the exact same bill of
materials as a certified appliance with or without the storage.
You may find the list of certified appliances here.
http://scn.sap.com/docs/DOC-52522
 SAN must be certified storage. You may find this list here.
http://scn.sap.com/docs/DOC-48516
 SAP HANA Installation must be done by a certified technology
specialist for SAP HANA installations. See exam
E_HANAINS131.
 The restriction on Production systems having to be the only VM
running on an ESX host has been lifted! This restriction is
expected to As always, multiple non-production HANA VMs can
run on a single ESX host without restriction.
 As of now vMotion, DRS, and HA are the only VMware features
that are supported in a HANA environment. Other features are
currently being tested by VMware and SAP.
 There are restrictions (mentioned below ).
 Capgemini’s planned vHANA environment will be
based on TDI architecture so restrictions listed
below will apply.
For a complete listing of all requirements, including a best practices configuration
checklist, please see the links provided in the “Sources” slide of this document.
Considerations
 Resources cannot be over committed. This means no over
provisioning of CPU or Memory resources of the ESX host.
 Sizing should be done exactly the same as bare-metal
appliances.
 VMware is currently limited to 64 vCPU and 1TB of memory.
Because of this limitation, the largest vHANA system supported is
1TB.
 Hyper-threading should be enabled for best performance,
however, the tables listed in this document should be referenced
for CPU:MEM ratios. With hyper-threading there is an expected
performance improvement of 10-20%.
 There is a maximum performance penalty of 10% with a
virtualized HANA instance.

Supporting HANA on Vsphere Effectively
What we have Learned
Establish a VMWare Community within hosting so that system administrators and basis
consultants can share information and establish common standards.
Encourage technical professionals to certify with VMWare at the level appropriate for
their roles. System Administrators pursue technical certification, others pursue sales
certifications.
Engage actively with VMWare Alliance to keep current on leading practice information,
both with the core suite and how to apply the technology to the SAP stack.
