Regular volumes Volume performance

limited by number of disks it has

“Hot” volumes can’t be helped by disks on other volumes

FlexVol volumes Spindle sharing makes

total aggregate performance available to all volumes


The new RAID issue

Disk drives are very big (1.5 TB).Reconstruct of failed, large, disk can take over

36 hours.Any media error on another disk during

reconstruct will cause a data loss.Adding disks to existing RAID group should not

put data in risk.

Traditional RAID types (like RAID/5) are not acceptable anymore


OK

NOTData Lost

Solution?

Mirroring

Is mirroringthe right solution?

Problems With Traditional RAID


RAID-DP: High Performance RAID-6

2,000 to 40,000 times more secure than regular RAID

More reliable than mirroring for double-disk failure

14% Parity Overhead vs. 50% Overhead w/Mirror(*)

72% more usable capacity than competitive offerings(*)

(*) Comparing 2P+12D vs. 7+7 Mirror

P DP

RAIDProtects against single disk failure

RAID DP Protects against any two-disk failure


Cost-Effective Data Reliability

The Problem Double-disk failure is a

mathematical certainty RAID 5 (single parity disk)

– Insufficient protection RAID 10 (mirrored copy)

– Double the cost

NetApp RAID-DP™ Solution Protects against double- disk

failure High performance and

fast rebuild Same protection and

performance as RAID 10 at half the cost

Resiliency Low High Med High


20%Physical Failures

80%Logical Failures

• Physical Failures = CPU, Disk, cables

• System Is Down Until Hardware Replaced

NetApp:

• Using Best of breed HW

• Hot plugable components

• RAID-DP

• Reboot takes 60 seconds

• File system is ALWAYS consistent

• Logical Failures =

Virus attack, bugs, accidental delete

• Requires recovery from tapes

NetApp:

• Invented Snapshot technology

• Smart instant backups

• Up to 255 Snapshots per volumeExample: Every hour for past 48 hours,

Every night for past 14 nights Every weekend for past 3 weekends

• No performance impact

• Backups stay online = fastest recovery

Source: Gartner

Reasons For Downtime


Instantaneous Backup, Zero Server Impact

The Problem High server utilization No spare cycles for backups Tape is slow, complex, &

expensive DR can be difficult to manage

NetApp Snapshot™ Solution Servers run apps, not background

processes Instantaneous backup and recovery Low storage overhead Application consistent

Traditional Backup Is NOT Practical
