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

• 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.
