Use Case

• Run thousands of financial modeling & stock trading apps that require high IOPS &

sub-millisecond latency response times

• Applications require “consistent” sub- millisecond latencies in order to meet SLAs

“We want to standardize on “All NVMe

platforms” in our datacenter and vSAN on

Dell with P3700 is the right step to do that”

- IT Director

Leading Investment Banking Firm runs Stock Trading & Financial Apps on All Flash vSAN

Challenges

• Unable to meet SLAs for stock trading apps on traditional SAN

• Financial Applications were ”sluggish” due to high and inconsistent latencies on

traditional storage

• Traditional SAN was too expensive with low consolidation ratios for financial apps

Benefits

• SDDC Initiative to go 100% HCI was fulfilled by vSAN

• Early Adopters of vSAN All Flash over NVMe (Intel P3700) to benefit from

consistent and sub-millisecond response times and consistently high IOPS for

financial apps

HPE Synergy is now certified for VMware vSAN - Composable

23

The first composable Infrastructure certified for vSAN

HPE Synergy—A perfect choice for vSAN

A core value prop of vSAN is that it aggregates all local storage disks—both SSD and HDD—

available on the hosts (compute modules) into a single data store shared by all compute modules.

With traditional rack servers, compute and storage do not generally scale independently, but with

HPE Synergy, you can scale storage and compute separately.

This makes it a perfect fit for vSAN solutions, allowing for storage capacity growth without

requiring additional compute resources to host them.

Key Benefits:

Disaggregated storage and compute

HPE Synergy with VMware vSAN provides the flexibility of thinly

provisioning software-defined storage volumes, independent of compute

resources.

Single infrastructure for any workload

HPE Synergy helps enterprises run vSAN in a single infrastructure,

addressing the needs of both traditional and emerging business applications.

High-Speed interconnect between frames

HPE Synergy provides a flat east-west Ethernet topology. This allows iSCSI

storage to be shared on a low-latency server-to-server connection,

including between HPE Synergy frames.

Next-Gen Storage Devices: Summary

46

Overview• Application performance needs are driving evolution of

fast storage such as NVMe & NVDIMM at a decreasing

price point.

• vSAN two tier architecture lacks parallelism & space

efficiency required to to take advantage of these fast

devices

• A single tier design is required for efficient use of

emerging devices like NVDIMMs for performance

oriented workloads.

Why do this?• Make NVMe more cost-effective for performance

oriented workloads

• Leapfrog competition by providing higher performance

& space efficiency with single tier design

• Enable NVDIMM as byte addressable to deliver

extremely high IOPS & micro-second latency for

performance sensitive apps

bution

Phase 1: Deduplication Performance Enhancements in 2 tier

48

1. Reduced CPU scheduling overheads• Offload compression and hash calculations to helper threads.

• Reduces overall load on plog (context in which dedup runs) with less thrashing

• Makes dedup more streamlined and more performant.

2. Improved performance with "read ahead" • Elevator algorithm “reads ahead” next 512K blocks while dedup engine is

processing current 512K block for calculating hashes, compressing data etc

• Improves read latency with parallelization (without “read ahead” this is a

sequential operation waiting for the previous task to complete).

• CPU thrashing due to "Read ahead" is mitigated with dedup helper threads



bution

Phase 2: Introduce new Single Tier Architecture

49

1. Single tier architecture with all storage devices in a given node pooled together for capacity• Much simpler disk group construct (eliminate tiers)

• Can add faster and slower devices into one single tier

• Provide host level deduplication capability.

2. Highly parallelized architecture to achieve close to raw device bandwidth/IOPS

3. One disk failure doesn’t cause entire disk-groups to be rebuilt• Metadata will be redundantly saved on the local node.

• Only missing data will need to be rebuilt from other nodes

• Reduces re-sync & rebuild traffic, so less impact on both network and storage, enabling faster recovery

from failure.

4. Enable inline dedup/compression/checksum/encryption

5. Flexibility to turn on space efficiency on a per vmdk basis• Provide flexibility to customer for max performance vs space efficiency



bution

Phase 3: Support NVDIMM as byte addressable

Architecting vSAN with Persistent DIMMs

1File System purpose built for All Flash. NVDIMM supported as byte-addressable device

2

Optimized architecture for higher IOPS and better space efficiency –

a) Store metadata, reduce write amplification

b) Staging deduplication and compression, checksum tables

c) Provide faster data caching

3 Leverage Large Capacity SSDs more efficiently

4 Tune vSAN algorithms for higher efficiency and performance using NVDIMMs

5 Long Term: Enable NVDIMMs as persistent storage when the densities increase

1. Enable vSAN to take advantage of NVDIMM devices as byte addressable • In single tier mode to store high touch metadata

• Ultra high IOPS & micro second latencies for performance sensitive apps
