Why do we need a new foundation?• We need more value from storage

• We need a next generation storage building block Not the same old SCSI + RAID

• We need a new entity – the non-stop virtual disc

• We need a 100x increase in MTBF and MTBSE

• We need NO storage-related downtime planned or unplanned

• We need NO SERVICE over the life of the storage subsystem no service needed is better than good service

• Spans all compute environments from SMB to HPC

• Will be the element used in future grid/cloud computing 11

• Environmental Vibration/Heat

Human Error

• Drives are too big!• Capacity

• Drives are too small!• Form Factor

• Controller software is dated Failing to control variability

Advanced Error Checking needed

• Intelligence is in the wrong places Cache/RAID & Drive Management don’t scale

• Fixing what “isn’t broken!” 50-85% of failed HDD are NTF

Improves Drive Environment DataPac (2 per ISE)

• Poor Vibration (~25 rads)

• Poor air flow and cooling due to obstructions

• Counter rotation for reduced vibration (~2 rads)

• Excellent airflow and cooling across electronics, obstructions designed out


• Done in increments of whole drives

• Partly because physical drive locations can vary

• When a drive fails the entire drive has to be rebuilt from parity including unallocated space

This takes days with large drives

If multiple drives fail they are rebuilt one at a time.

Conventional RAID

• Done in increments of drive heads (surfaces)

• Because physical drive locations don’t change

• Patented In-situ head sparing

Only the affected head(s) are rebuilt and only if they have allocated space.

Rebuilds take place in parallel

Significant reduction of rebuild time on large drives

ISE RAID


• Larger foundational storage element

10-20 times larger than drives

• Sealed DataPac managed as one element:

3½” drives (Ten per DataPac)

2½” drives (Twenty per DataPac)

• Fewer FRU’s

8 instead of up to 30 per standard enclosure

“Sealed” DataPacs

• Easier to manage

• Easier to scale

• Reduced complexity

• Higher reliability and availability

Benefits


Ability for the user to

• Replace Individual Platters

• Replace Heads

From the Product Description:

“non-removable disk packs were sealed and included the head and arm assembly.”


Code does not have to deal with variability from

• Drive relocation

• Manufacturer mix

• Drive generations

• Firmware differences

Made Possible by Controlling Variability

• Simpler and more efficient controller code

• Drives work together

• Less qualifying to achieve bug free interaction between controller and groups of discs

• More efficient striping and performance algorithms

Result: 25-30% greater performance per drive

Benefits


With traditional storage systems… as utilization goes up, performance drops


With the competition… as utilization goes up, performance drops

With ISE… as utilization goes up, performance stays strong


• Each ISE’s adds additional cache

• Performance scales linearly

• Cache is close to the storage where it should be.

Made Possible by Controlling Variability

• Frees the array controller for higher functions such as:

• virtualization

• host connectivity

• system management

• Increases in storage capacity do not reduce resources on a per-drive basis

• Array controllers can scale much further as a result

Enormous Flexibility in Scaling.

Each ISE has redundant hardware RAID controllers

• Each manages it’s own fixed number of discs.

• Adding more storage adds more RAID controllers

• Controllers are close to the storage they manage.


DIFFERENCES146GB = 58,540 IOPS300GB = 30,480 IOPS

ISE- 42U IOPS Comparison


• Automatic processes

• Reset drive

• Power Cycle drive

• Remanufacture drive

• Recalibrate servos/heads

• Reformat

• Rewrite servo/data tracks

Drive ReconditioningPreventative and remedial

• 208 ISE’s running 5,900 drives for 19 months with known bad drives:

• Zero service events

• Equivalent number of SBODs and drives:

• Would expect 65 service events with good drives

• Elimination of over 100 service events

• Scalable from 1TB to 1PB within a single system

• Highly reliable• Leading performance• 100% Usable Capacity after RAID• Features full featured SAN

capabilities ICON Manager TimeScale replication solutions

• Fibre channel and iSCSI within a single system

• Five year warranty


Xiotech’s ISE technology provides the best value ofANY storage offering on the market today.

• More performance with less hardware: The industry’s most efficient performance and scalability.

• Half the ongoing storage costs: Five-year warranty and lower management expense.


Ongoing operating costs account for more than 60%of a typical SAN’s total cost of ownership.

• Maintenance expenses, particularly after the warranty expires

• Downtime events

• Resource utilization, such as power, cooling, and floor space

• Administration / labor costs


ICON Manager dramatically simplifies storagemanagement, saving you time and money.

• Perform most common storage tasks quickly and accurately using wizards.

• Create volumes and assign them to servers and VMs with just a few clicks – from a single pane.

• Manage a lot more storage and still have time to focus on other important projects.
