Escalating CAPEX

What your IT Department might say:

We need to buy another new storage system

We have a lot of capacity, but we can’t use all of it

We need another new product to fix that problem

Paying for storage you can’t utilize?

IT staff utilized efficiently?What your IT Department might say:

We spend too much time managing storage

We don’t have time to work on that project

We work nights and weekends to keep up

Training for just that product is an entire week

Source: IDC, 2004

The cost of managing storage is rising to as much as 8x the acquisition cost

Virtualization

Performance optimization–Automatically read/write data to all spindles–Efficient use of disk platters – use outside

sectors first–I/O concatenation–Elevator sort

Change RAID type for any volume online

Automatic storage-level defragmentation–Automated block placement maximizes

Dynamic Capacity “Thin Provisioning”

Steven Dahlin


Traditional SANs

Traditional SAN storage allocation – Disks are formatted with a specific RAID type– LUNs are carved from the RAID type– LUNs are assigned to specific servers– Administrator must OVER ALLOCATE physical storage

to servers, creating islands of storage

THIS MEANS ALLOCATED BUT UNUSED STORAGE!

Data Data

Data

Conventional Allocation

Database

E-mail CRM


Traditional SANs

Why is the traditional SAN structure inefficient? – Disk storage is captive to specific servers, not all applications

grow at the same rate.

– How do you re-purpose storage? Back up resize, restore - time consuming, costly, dangerous, not always possible

– Inefficient use of physical storage, not better than DAS.

– If you have storage that cannot be freed up, you have to purchase additional storage prematurely

Compellent’s ApproachTraditional Disk Mapping


Dynamic Capacity Difference

Dynamic Capacity – On line volume expansion is NOT thin provisioning

• Thin provisioning is the ability to provide logical volumes to servers without allocating any physical blocks of storage

• Compellent supports both thin provisioning and the real-time, on-line expansion of logical volumes

Dynamic Capacity Difference

Dynamic Capacity Operates on a

block level - Why is this important?• OS, file system and application

independence• The underlying Dynamic Block

Architecture has laid the groundwork for the possibility of Dynamic Capacity

• Blocks are only assigned to a volume when the server requests a write

• Supports all types of FC and SATA disk in the same storage pool

• Physical storage growth is on-line without server or storage system downtime or performance degradation

Dynamic Capacity Benefits

Benefits– Less storage is required up front– Reduce disk spending by adding storage incrementally– Eliminate downtime due to volume expansion– Automate capacity planning– Increase system performance with disk operations based

only on written data (copy/mirror/migrate/RAID rebuild, replication)

– Unused physical storage is available to all volumes– Add more servers per storage system– Significant Return on Investment (ROI) potential


Data Progression

Steven Dahlin


Terminology

ILM (Information Lifecycle management)– Process of managing data throughout its lifecycle across

different storage media– ILM has intelligence to look into the content of the files for

application awareness

DLM (Data Lifecycle Management)– Process of managing data throughout its lifecycle across

different storage media – DLM is focused on the movement of data

Source: Industry sources


Industry Benchmarks

• Most data is inactive and can be progressed to lower performance

disk/RAID

• Industry analysts and SNIA agree on the 80% guideline for idle data

• Compellent can provide positive ROI at only 35% idle data or more


Current Barriers to DLM

• Data classification requires manual intervention

• Available only on expensive, monolithic storage or dedicated software / hardware solutions

SAN

• Dedicated to today's drive technologies

• Available only on specific OS

• Operates only at the file level

• Does not address use of snapshots


What does Data Progression do?

• Allows a volume to exist across different disk types, sizes, speeds and RAID levels.

• Monitors I/O and distributes data based on block access patterns• Leverages cost and performance differences between disk types -

maximizing use of SATA disk for bulk storage and FC disk for high speed data access

• Optimizes the use of RAID 10, RAID 5 (5) and RAID 5 (9) to further enhance disk utilization without sacrificing performance

• Snapshot storage is automatically placed on the lowest tier and RAID level

• Enables the adoption of newer disk technology while fully leveraging previous disk investments

• Provides significant reduction in IT spending

Data Progression aligns storage to data value

Data Progression

Automatically create volumes or files that span multiple tiers – Volumes are presented that look like a

large drive to the server

– Within the volume, multiple types of storage are used and data is optimally placed

– No impact to the server

– Only blocks are moved, not files

– Files will be spread across different storage types

Data Instant Replay

Steven Dahlin


Traditional Snapshot Technology

Copy on Write Limitations– Performance degradation– Additional storage captured– Storage must be pre-allocated for snapshots, reducing

the amount of available storage– Read only snapshots when recovered– Might only be scripted or GUI driven or vice-versa– Do not automatically expire after preset period– Limited number of snapshots


Traditional Snapshot Technology

Full Copy Limitations– Consumes additional storage capacity– Time to create replacement volume substantially higher– May incur higher software licensing fees


Compellent Data Instant Replay

There is a better way today! • Intuitive scheduling interface• Space efficient, time based

replays• A Replay can be mapped to

any server• Replays are read and write• Can recover without full clone• Extremely small amount of

storage used
