What is a Virtual SAN?DataCore’s Virtual SAN definition:

DataCore’s Virtual SAN is where SANsymphony-V is used to create high-performance and highly-available shared storage pools using the disks and flash storage in your application servers

DataCore Virtual SANs are comprised of: Two or more physical x86-64 servers with local storage, either running SANsymphony-V directly on the hardware (root partition) or from within a virtual machine

Benefits of deploying Virtual SAN

ApplicationServer

ExternalStorage

Provides persistent storage services as close to the application as possible without having to go out over the wire to access storage

► RESULT: Lower context switching -> lower latency -> improve application response time

App Servers(Hosts)

External SANs

Provides access to storage across a cluster of servers utilizing local disk and flash storage

► RESULT: Eliminate the need for complex external SANs -> reduce overall infrastructure costs

Top Reason You’re Considering Virtual SANs► I/O bottlenecks slowing down virtualized apps► External shared storage for cluster of servers is

too expensive► Current shared storage system creates a

single point of failure► Other

Which type of scenario are you evaluatingvirtual SANs for?

► VDI (virtual desktops)► Latency-sensitive database apps► Large clusters (>32 nodes) for Big Data► Small, remote office / branch office► Other

Poll #2


Virtual SAN Use Cases


Use Case #1: Latency-sensitive app Speed up response and throughput by:

► Leveraging flash memory as persistent storage close to the applications► Cache reads and writes out of even faster server DRAM memory

Use Case #2: Compact Servers and ROBO

Put the internal storage capacity of your servers to work as a shared resource while protecting your data against server outages

Branch Office[Virtual SAN]


Use Case #3: Virtual Desktops

Run more virtual desktops on each hypervisor host and scale them out across more servers without the complexity or expense of an elaborate external SAN

Scale out from2 to 32 nodes

Scale up to32 PB

Accelerate up to50 million IOPS

Which of the following would you rate as most important in choosing a virtual SAN solution?

► Supports multiple hypervisors (VMware, Hyper-V, etc)

► Can provide high-availability even for a cluster of only 2 servers

► Does not require flash to speed up performance► Taps into existing external SAN for extra capacity

and additional disaster recovery services24
