 Increased Testing Validity
 eg: Reduced Time to Validate Environment
 Combined Testing of Functionality with Network Security

5. 5
Database Advantages in vCloud (Continued)
 No Need to Manually Manage Per VM Reservations
 Declarative Service Defined Architecture
 Portability Between Private, Semi-Private and Hybrid/Public Cloud

 No Support for RDM
 No Support for Shared VMDK’s
 No Support for Multi-writer flag
 All Virtual Disks on Same Tier of Storage
 All Virtual Disks Contained within Single Datastore (by default)
 No Control Over Number of Datastores
 No Control Over NUMA Node Size

CPU & Memory
 HW v8, v9 or v10?
 Rightsize vCPU config
 Respect NUMA, vNUMA
 vCPU’s are a single thread
 Memory is cheap performance, direct relationship to read IO
 Server Side Cache can reduce VM memory requirements

10. 10
Approx DB Memory Architecture (high level)
Client sessions /context
Main DB memory
Oracle – SGA
SQL Server – Buffer Pool
Operating System
Large DB memory and OS Cache => caches more data blocks => can minimize access to disk
So set memory reservation to protect this

11. 11
Network
 Use vmxnet3
 Jumbo Frames
 Evaluate latency settings:

12. 12
“Your database is an extension of
your storage”

13. 13
Storage
 Use top tier storage policy
 Watch fast-provisioning disk chain length
 Disk Alignment
 Use multiple vmdks on multiple vSCSI adapters
 Use multiple data files or log files per vCPU
 Queues are everywhere

14. 14
Typical Storage Sizing and Performance
SIOC Enabled when more than one VM share datastore - vCloud

Best Practices
• Enable traceflag 834 in SQL Server for Large Page Support and 2371 for dynamic automatic statistics update.
• Service account that SQL Server is running under must have the “Lock Pages in Memory” privilege set in Local Policy
Partition:NTFS–64kclustersize

Can be Shared under
one drive and VMDK

Resource Allocation Models

21. 21
Organization Virtual Datacenter – Allocation Models
 Reservation pool resources
allocated to the organization
virtual datacenter are
completely dedicated
 Allocation pool is a pool of
allocated resources with a
certain percentage guaranteed
 Pay As You Go model provides
the illusion of an unlimited
resource pool – Can be capped
Consumer #1
Guaranteed Resources
Consumer #2
Guaranteed Resources
Reservation = Limit

23. 23
Storage Profiles
• The organization administrator can
offer different classes of storage
within a single virtual datacenter
• Virtual datacenters, vApp
templates, and media can define a
default storage profile to be used
• VMware vSphere Storage DRS™
functionality can be used within
VCD, allowing for Storage vMotion
between datastores within a cluster
based upon metrics defined
(available space and I/O latency)
• Do not use I/O Load Balancing
when using Array Auto Tiering
• VM allocated only one tier of
storage

24. 24
Profile Driven Storage & vCloud Director
 Storage Profiles are now represented in vCloud Director
 This allows storage to be managed on a per ORG vDC
 If the Storage Profile associated with a vApp is changed, the vApps
are automatically Storage vMotioned to a compliant datastore

25. 25
Storage DRS & vCloud Director
 vCloud Director Interoperability/Support for Linked Clones
• vCloud Director will use Storage DRS for the initial placement of
linked clones during Fast Provisioning
• vCloud Director will use Storage DRS for managing space utilization
and I/O load balancing

26. 26
Increasing Database Performance in vCloud Director
 Queue depth
 Larger # of datastores
 Storage DRS Anti-Affinity Rules – Separate VMDK
 No Fast Provisioning for Production VM’s
 Server Side Caching

27. 27
Ensuring Quality of Service

28. 28
Enabling QOS
 CPU and Memory
 Use DRS for auto migration
 Use the right allocation model
 Size Application for VM Allocation Model
 Network
 Use NetIOC at lowest layer “carefully” if necessary
 What about Load Based Teaming? Not with VXLAN!
 Storage
 Use storage profiles appropriately
 Leverage array based hot block migration
 Storage IO Control
 Storage DRS

Slide 30
How vCenter Operations Delivers a New Model for Operations
 Tightly integrated with vSphere
 Self-learns “normal” conditions using
patented analytics
 Aggregates underlying metrics into
Workload, Capacity, Health scores
 Powerful visibility and drill down from
datacenter to component level
 Smart alerts of impending performance
degradation
 Integration of 3rd party monitoring tools
An integrated approach and patented analytics to transform
how IT ensures service levels in dynamic environments

Important Architecture Traps to Avoid
 Don’t disable DRS
 vMotion Slot Size and Host Sizing when using HA % Admission Control
Impacts Maintenance and HA Failovers
 Max # of LUN’s per Host / Cluster Impact on Size of Cluster
 Host NUMA Node Too Small for Optimal Performance and
Efficient Utilization
 NUMA Node Size Not Known in Cloud
 Size Hosts and Clusters to Allow Maintenance and Failure Resource,
Consider Sacrificing Optimal Performance During Failure
