Device-centric Silos

✖ Static classes of service

✖ Rigid provisioning

✖ Lack of granular control

✖ Frequent data migrations

✖ Time consuming processes

✖ Lack of automation

✖ Slow reaction to request

Software-Defined StorageStorage Today 

• Policy-driven automation• Common across arrays• Dynamic control

• Server SAN• Flash accelerated• Distributed

The Hypervisor is Best Positioned to Deliver the Software-Defined Storage Transformation

5(1) Gartner Market Trends: x86 Server Virtualization, Worldwide, 2013

Why the Hypervisor:

• Over 70% of x86 server workloads are virtualized1

• It’s inherently app-aware

• Sits directly in the I/O path

• Has global view of underlying storage resources

• It’s hardware agnostic

“We now have an environment that we can grow organically or shrink organically depending on what our needs are… very linear scaling. It allows to scale our deployments the way we want to and not get locked in. This is the right way to do storage, it really is!”— Alan Sprague System Administrator Oregon State University, College of Business

Customer Case Study: Oregon State UniversityHigh Performance for VDI with Budget-friendly Scaling

40

Challenge• Storage overburdened by VDI workloads• User login took over 20 minutes during peak times• Recomposing VDI environment took 10+ hours• Manual resource-balancing not sustainable• Limited storage budget

Solution• Virtual SAN deployed on Dell servers

Results• Drastically better performance: user login time reduced from 20 mins. to 1 min.

• Increased VDI scale: could support 170+ additional users on existing servers/network

• Simplified management: resetting virtual desktops reduced from 10 hours to <2 hours

• Lower cost and ease of scale: lowered acquisition costs by 75% and enabled easier scaling for future needs

“Before Virtual SAN, we had no ability to scale. Now…it’s a piece of cake; If I want to add additional capacity, I just add an additional server. I don’t have to worry about whether my SAN can grow or not.” Alan Sprague,

41

Challenge• Aging SAN reaching end of life; too expensive to replace/upgrade

• SAN overload resulting in frequent database latency issues; application crashes, slow screen refreshes, delays accessing patient records and slow reports

• Did not want to introduce new vendors in the mix

Solution• Business-critical Applications on Virtual SAN

o GE Centricity EMR application, PM application, PACS applicationo Siemens Soarian Clinicalso Oracle database, SQL database

• Cisco UCS C-series servers

Results• Super fast application and database response times : 200 millisecond latency

reduced to under 1 millisecond; reports completed 6 times faster

• Reduced maintenance time by 1/10th• Budget-friendly scaling enabled new projects on Virtual SAN

“We actually had clinics calling us up to say how much faster the apps were running once they were in a pure Virtual SAN environment….It seems like the more applications we migrate to the Virtual SAN, the more departments are requesting to be on it.” Chad Elliott

Customer Case Study: Peter Cremer (Global Chemicals Manufacturer) transforms storage in secondary datacenter

42

Challenge• Rapid business growth strained storage resources

• Aging IT infrastructure causing system crashes and expensive outages

• Customers demanded failsafe business continuity

Solution• Virtual SAN deployed on Dell servers

• vSphere Replication and vSphere Data Protection

• Applications virtualized: Microsoft Dynamics ERP, Microsoft SharePoint, Targit Business Intelligence, Quality Control software

Results• Higher performance for data warehousing applications : queries that took 15

minutes now take less than 15 seconds

• Quickly double storage resources: positioned company to quickly scale storage in fast moving business

• Assured system uptime: Improved data protection and ability to quickly recover in the event of any outage

“We can maintain our mission-critical manufacturing, ERP, data warehousing onsite…. We started the project from a perspective of risk management but we soon realized its actually a competitive differentiator. Our IT infrastructure is now something we can show off to our customers.” Steve Taylor

Customer Case Study: IBC Bank

43

Challenge• Insufficient storage for Mirage environment; wanted to scale storage without

impacting existing environment

• Traditional SAN vendors quotes for buying new storage were beyond budget and not sustainable to grow capacity in long run

• Preferred solution that worked with VMware vSphere and Horizon suite

Solution• Virtual SAN deployed on HP servers

Results• Significant cost savings: saved 50%-60% in setting up VSAN for VDI than buying

storage arrays

• Ease of upgrading hardware in future : can leverage latest servers and hardware by swapping out a few components at a time

• Lower day to day maintenance: could grow VDI environment without adding any additional management overheads

“Virtual SAN lets us buy what we need when we need it.  With non-disruptive scaling, we can add more capacity or increase performance at any time without interrupting our operations. ” Chris Reynolds
