Customer Pain Points With Storage
 Too much guesswork
 Too many silos
 Operational mismatch between virtualization and
storage
 Performance degrades with time
 Lack of end-to-end visibility
 Trouble shooting is hard
 Overprovisioning for performance
 Management inefficiencies
 Missed opportunities with DAS
How do we break silos?
How do we align application
requirements to storage capabilites?
How do we increase efficiency?

Software-Defined Storage
Automation with policy-driven storage provisioning - with SLAs
replacing technology details
Virtual volumes - transparent mapping between large volumes and
the VM disk images within them, to enable performance and data
management optimizations
Commodity hardware with storage logic abstracted into a software
layer and scale-out architecture
Programmability - management interfaces that span traditional
storage array products, separating "control plane" from "data plane”

VM Storage Provisioning Pre-SDS…
Day 1 Day N Day N++
Setting up storage requires:
1. Spreadsheet black-magic
to determine right
configuration
2. Several additional steps:
• Build disk pools
• Assign RAID levels
• Create LUN/volumes
• Zone and map LUNs
• Format LUN/Volumes
• Assign data services
(Replication, etc.)

Design Scenario
You have been asked to plan a storage design for the rapidly growing
software development company, PunchingClouds Inc.
PunchingClouds Inc. is currently in discussions with their storage
vendor on pricing for new storage arrays to accommodate a variety of
workloads, but want to assess all options in moving towards a SDDC
 Performance is critical for some application tiers, but not others
 The need to maintain manageability as the organization grows, as no
additional staff will be hired in the short-term future
 Regulatory compliance is critical for a subset of applications
 Currently a single storage admin handles operations for the
enterprise

Step 1: Assess
Current State
 Average storage capacity for typical workloads?
 What are the application I/O profiles?
 Are multiple tiers of storage needed?
 Are there existing SLAs for storage performance?
 Project budget?
 Preferred storage vendor?
 Preferred storage protocol?
 Can existing storage be used?

39. 4242
Business Requirements
 Provide differentiated storage tiers to match application profiles
 Different tiers can be charged at different rates
 Allow end-user to choose the right storage tier/cost for type of
workload
 Flexible way to control or ensure storage performance
 Minimize the capacity and cost of storage
Constraints
 Existing storage vendor
 Minimal storage staff
 Re-use existing storage infrastructure

2
1
Software-Defined storage can enable
efficiencies across multiple solution pillars within
your datacenter
Using an architectural methodology (i.e. “The
VCDX Way”) can help ensure successful
adoption of the right solution for your datacenter
4
VMware enables Software-defined storage
through both native solutions and eco-system
partnering
Software-Defined storage solutions can provide
both capex and opex savings as your
datacenter grows
