DataCore is committed to creating an

enduring

and

dynamic

software-driven storage architecture liberating

storage from static hardware-based

limitations

The DataCore Vision

Pool

all storage capacity and

provide centralized

management

The right software must be able to do a few things…

1

Enable

different

storage devices to

communicate

with one another

Why Software-defined Storage?

Make hardware maintenance,

data migrations, and hardware

refreshes

easy

4

Separate

advances in

software

from advances in

hardware

One Software Platform

Preemptive Tier Space Management

A customizable percentage of capacity is kept available for new allocations and

promotions

Percentage applies to any tier within a pool except the lowest

SAUs that heat up may get promoted faster if there is free space available in the tier above

New allocations go to the highest tier according to the Storage Profile first

SAUs allocated in the reserved space may prompt

migrations to keep space clear

Disk Pool – Auto Tiering

Tier1

Write-aware auto tiering

Takes WR IOs into account when building the heat map

Can be turned on/off at the Virtual Disk level

Configurable via the Storage Profile

Display change; SAUs are now ordered by ‘hotness’

in descending order from left to right

IO per second and IO latency counters

Improved rebalancing logic takes Virtual Disks

into account when leveling SAUs across spindles

Avoid piling up SAUs on few physical spindles

that belong to the same Virtual Disk

Ensures uniform distribution of SAUs per VDisks

Eliminates recovery of entire pool in case a pool disk fails

A new wizard-driven “Purge” action figures out which Virtual Disks

are affected, what data (SAUs) they are missing, and how to proceed

Mirrored VDisks get restored by recovering the missing SAUs from the

‘good’ side

Single and Dual VDisks are brought back online but with unallocated

“holes” in them (no mirror to recover from)

Initiating a pool recovery is a manual action due to its potentially

destructive nature to single/dual VDisks a well as Snapshots and

Rollbacks.

Additional System Health displays to visualize

storage allocation and channel utilization

Display IO/s and IO latency per Disk in Pool

Heatmap

Create a physical disk max. latency counter

Performance Counters for Host port pending or

outstanding commands

More Insight from Heat Maps

Multi-core CPU Thread Scheduling Optimisation

Dynamic scaling of poller thread instances

Always use at least 2 threads (unless <=4 CPUs)

System spins up more threads if front-end workload

demands it and more CPU cores are available

New performance counters

For iSCSI and Remote Replication:

10/40 GbE Emulex NIC

10/40/56 GbE Mellanox NIC

40/56 GbE Mellanox Switch

NIC Teaming (combine 2 or more NICs as one)

Aggregate bandwidth and/or

Loopback vDisks now appear in a new

“DataCore Disks” folder under the server

Make it easier to serve a vDisk to a

SANsymphony-V Node

Extend Smart Deployment Wizard to assist

with multiple setup

Up to 32 nodes per Server Group

Combine traditional DataCore Servers

and Virtual SAN nodes within same

group

Storage Domains

►

Access Control

• Group and subset definition

• User controlled configuration changes to defined subsets of the

system

►

Storage Policy

• Storage location (“What pool”, “where in the pool?”)

• Quality-of-Service (bandwidth, IOPs)

• Quota Management (“how much pool space”)

SSV Storage Features

Shared Resources

Domain A

Domain B

Domain C

A Storage Domain is a subset of resources or a

group of objects

Individual users are authorized per Storage

Domain

►

Users can change the resources/objects

inside a Storage Domain

The Storage Policy determines:

►

Storage location; which disk pool(s) a

domain can use

►

Storage class; what types of storage

(tiers) a domain is allowed to use

►

Quotas; how much capacity a domain can

consume

►

Quality-of-Service; how much bandwidth

Continuous Data Protection (CDP)

►

Long-term CDP

• Retention time only limited by storage capacity

• Optimize resource utilization

►

Rollback improvements

• Rollbacks persist without impact to parent Virtual Disk

►

Application-consistent rollback point

• Mark known-good points in the history log

Data Mobility

►

Move Virtual Disks across servers

• Single operation to relocate a VDisk on the fly

– Move VDisk to another pool if performance requirements change

– Move VDisk to another node to overcome IO bottlenecks

►

Maintenance Enhancements

• Transition ownership of VDisks between nodes

• Maximize availability in maintenance scenarios
