5. 5 Storage bottlenecks cause 70% of VM performance issues Traditional SANs weren’t designed for virtualization Random I/O patterns create storage bottlenecks (“blender” effect) Not enough storage controller cycles VM workloads are dynamic

12. © PernixData. All rights reserved. 12 What is a block? A block is a chunk of data. A single unit in a data stream. This unit would be a read or a write from a single I/O operation. Block “size” refers to the payload size* of the unit. * 256K block has 64 times the payload compared to a 4K block. The importance of block sizes

13. © PernixData. All rights reserved. 13 Why does it matter Large block require more effort/resources to pass across storage stack, impacting performance of VMs and infrastructure. Processing overhead on physical HBAs, switches, storage controllers, etc. Bandwidth across storage fabric. Protocol characteristics Queues and their limits The importance of block sizes Credit: Chad Sakac

14. © PernixData. All rights reserved. 14 Traditional methods of visibility of block sizes Kernel statistics using vscsiStats. Cannot present data in real time. Cannot provide context relative to other workloads. Extremely time consuming. Command line only on a host. Not visible in vCenter. Storage array Not VM aware Measuring at the wrong location. Unknown method of measurement. Not treated as a first class citizen. Storage array dependent. The End result… Block statistics are largely invisible. The importance of block sizes

FVP: Strategic platform for storage acceleration Turn any SAN into an all flash array Infrastructure level in-memory computing 10x faster than storage alone 17 Any shared storage PernixData FVP Software Low latency reads and writes using server flash / RAM Performance

18. © PernixData. All rights reserved. 100% non-disruptive 18 Hypervisor (vSphere) No changes to VMs Transparent to storage (FC, iSCSI and NFS) Any Server Any Storage Any Flash/RAM PernixData FVP Software No reboots, application rewrites or process changes

19. © PernixData. All rights reserved. 19 Acceleration medias SSD / PCI-E / RAM Flash: SSD  Easy to install.  Convenient form factor. Flash: PCI-E (NVMe)  Requires available PCI-E slot  Limited choices in Blade environments  More predictable experience. High bandwidth and no SATA/SAS controller RAM  Volatile media. Think about Write-Back design and fault domains.  Extremely low read and write latency. Any block size.

The company will pay another $400 if the following performance guarantees are not met after FVP software is installed and run using pre-approved testing criteria: 10x faster VM performance with a disk-based array 5x faster VM performance with a hybrid array 2x faster VM performance with an all-flash array
