IT Considerations

What’s the order of

importance?

Price

Total Cost of Ownership (Lifecycle)

Reliability

Redundancy and Fault Tolerance

Data Availability

Uptime & productivity

Scalability – grow capacity & performance over time

Performance

Bandwidth vs. transactional

Support multiple applications

Flexibility

Repurpose resources as needed

Eliminate pre-planning shortfalls

Ease of Management

Technology Briefing – PerformanceThroughput – bandwidth (i.e. data pipe)

High bandwidth applications

Disk backup/Archival

Video & Surveillance

I/O – processing power

Transactional applications

Database (SQL) and E-mail

Virtualization

Drive performance

SATA: High capacity, low cost, slower RPM (7200), single path

SATA/SAS hybrid: High Capacity, medium cost, slower RPM (7200), dual path

SAS: Lower capacity, higher cost, faster RPM (10K/15K), dual path

6 disks

• Lower Cost

– Decreased management

requirements

– Reduced capital

investments

– Less power

– Uses full capacity of all

disks

• Higher Performance

– Optimized RAID level for

each application

– Volumes can span all

disks

– Greater disk utilization

Virtual Storage Benefits (continued)

• Ability to configure any combination of volume types; no

need to make any global decisions up front

• Allows all of the available storage capacity to be utilized,

without any wasted space

• No need to pre-allocate drives to a specific storage pool

• Ability to re-configure any volume when needed; you are

not locked into anything

• All volumes are on-line during any grow or reconfigure

operation

Product Application – Storage Consolidation

Product Application – Virtualization

Product Application – Disaster Recovery

• Extended warranty options

• Hardware upgrade as needed– Add secondary controller as necessary

– Scalability beyond primary array as capacity needs dictate

• Availability of firmware upgrades– Service, warranty or maintenance agreement required?

• Performance capability for future applications– Transactional processing power to support upcoming applications

– Bandwidth available to support upcoming applications

• Available connectivity for planned infrastructure upgrades– Massive data pipe for GbE networks

– 10GbE connectivity today w/ low-cost 10GbE uplink

Extending the life of your SAN

• Open architecture (grow capacity as needed)– Support for non-proprietary, off-the-shelf disk drives

– Support for mixed drive environments• SAS & SATA

• Mixed capacities

– Scale performance with capacity

• Volume virtualization– Eliminate need for RAID set containers

• Added flexibility for provisioning virtual volumes across disk pool

• Better capacity utilization

• Increased I/O performance

– Support volume reconfiguration on the fly• Capacity expansion

• Reconfiguring RAID levels

• Migrating from physical disks

• Change stripe depth

Extending the life of your SAN (continued)

Highly integrated single chip solution allows system to handle speeds of over 80,000 I/Os per second.

• Built-in RAID controller offers RAID 0, 1, 1+0, 5 and JBOD.

• Built-in IP SAN Device Manager (IDM)

• Allows remote access

• Manage multiple SAN arrays from a single screen

Systems support off-the-shelf, non-proprietary disk drives.

• User may purchase and install any hard drive from our recommended list

• Save on costs by sourcing drives through your own vendor

Mix and match drives

• Drives of various sizes may be used and configured with multiple RAID types & volume segments on a single drive

Volume virtualization

• Up to 1,024 Virtual Volumes (256 accessible per initiator)

• 1024 target nodes

• Online Capacity Expansion – without disruption to the system

• Volume reconfiguration – without disruption to the system

• Instant Volume Access

• Access volume before initialization process is complete

Key Selling Points –xStackTM SANs

Key Selling Points – DSN-5000 family

DSN-5000 series brings redundancy and expandability• Dual-controller support for HA- High Availability

• Supports up to six DSN-5000 expansion arrays

• Up to 84 drives in a single logical array

• 168TB raw storage capacity using 2TB drives

• Larger drives supported as they become available

Supports 8 x 1GbE iSCSI data ports per controller• DSN-3200 & DSN-5210

• Compare to typical competitors with 2 to 3 GbE ports

• 8 ports can be aggregated for 8GbE throughput.

Supports built-in 10GbE interface• DSN-3400 & DSN-5410

SAS and SATA-II* support with DSN-5000 series• SAS and SATA drives supported within the same array

* SATA-II only supported in single controller mode.

Positioning

A reliable data-center class SAN array for customers requiring a path to HA-High

Availability and scalability (DSN-5000 series).

Cost alternative to established SAN platforms

No need to purchase proprietary disk drives at proprietary prices to grow array

Support off the shelf disk drives

Future f/w releases made public – no maintenance contract needed

No a-la-cart licensing pricing strategy

Performance leader

4 times or greater throughput performance vs. competitive products

Massive data pipe configurations & full 10GbE line speed

8xGbE data ports per controller

1x10GbE data port per controller

Flexibility

Volume Virtualization

Volume expansion & reconfiguration on the fly

D-Link Value Proposition

Case study – Luce Forward

Need additional

mass storage for

non-critical data

(Litigation Support)

Desire offsite

protection as

well as no need

for tape backup

Current NAS

with NetApp

for critical

data.

Case study – Luce Forward (continued)

• D-Link

– Enterprise class solution

• Price effective

– Allowed for on-site replication as well as off-site

• Using SureSync for replication

• Opened the door

– D-Link solution proved to be a great solution for both price and fit.

– Considering additional uses for future projects.
