10. Benefits of Premium Features
Storage Partitioning
Allows the sharing of capacity across multiple servers
User can define which server(s) can have access to specific data
FlashCopy
Supports utilization of separate data copies, for a variety of uses such as hot backups or application testing
No affect to production data – remains online accessible
Instantaneous
VolumeCopy
Allows for redistribution of data from older, slower disk drives to faster and/or higher capacity drives
Optimizes application performance and/or capacity
Complete separate physical copy of data that can be used for analysis or testing with no effect on production data

11. What is Storage Partitioning?
A logical unit consisting of one or more volumes that can be accessed by a single host or shared among hosts
One or more volumes are mapped to an individual host or host group
This volume-to-LUN mapping defines what host or host group will have access to the volume
Partition access is maintained at the controller level
LUN 1 2
Logical partition A
Logical partition B
Logical partition C
unmapped volumes
Host A
Host B
Host Group C

12. A point-in-time image can be created in seconds
What is FlashCopy?
A point-in-time (PiT) image of a logical drive
Logical equivalent of a physical copy
Features:
Instantaneous copy
Requires less disk space than a full copy
Map-able to any host
Can be read from, or written to
Primary uses:
PiT backup image
File restoration
Data mining / analysis

13. Fast copy of data with no server cycles
What is VolumeCopy?
Complete (byte-by-byte) PiT replication of one logical drive (source) to another (target) within a storage system
Target logical drive also referred to as a clone
Eliminates I/O contention on the primary logical drive
Primary uses:
Full PiT data set available for analysis, mining, testing, backup
Migrating data between storage tiers
Production Server
Analysis Server
PiT Clone

Volume Copy
Fast copy of data with no server cycles

14. Selecting A Drive Type Understand customer’s requirements
Highest performance or highest utilization.
Best $/GB or balanced price/performance.
Understand application requirements
Highest IOPS or highest MB/s.
Heavy usage data or static data.
Understand drive characteristics
Time to data
Data transfer rate
The most important thing you can do is understand the customer requirements. All decisions start with this basic knowledge. Are they looking for the highest performance, or the highest utilization? Are the looking for the best price per gigabyte, or the balanced price / performance? Many times, these are configuration opposites. Customers always want it all, but it’s important for them to understand that there are often trade-offs.
It’s also important to understand the customer’s application. Is it transactional and therefore requires good IOPS performance? Or is it bandwidth-oriented requiring throughput performance? Is the application data static and rarely accessed? Or does it see heavy usage?
Additionally, you need to know which drive is best suited to meet the customer’s requirements, and the application’s requirements. FC and SATA drive are very difference, so understanding how specifications such as time to data, data transfer rate and command queuing are important relate to performance is very important.
Now that we’ve asked all the questions, let’s look at some answers.

15. Understanding Performance
Two primary metrics
IOPS
Measures random, small-block I/O
Transactional applications such as OLTP, databases, Exchange
MB/s
Measures sequential, large-block I/O
Data-intensive applications such as rich media, 3D modeling, simulation, high performance computing

16. IOPS IOPS measures random, small-block I/O
Key drive-based performance enablers:
Seek time, latency, rotational velocity, command queuing, number of drives
IOPS performance is heavily dependent on the number and type of disk drives
SAS drives have faster seek time, lower latency, faster rotational velocity, and better command queuing compared to SATA
Drive-limited configurations can result in similar performance between systems with very different maximum capabilities FC
SAS
SATA

17. Throughput MB/s measures sequential large-block I/O
Key drive-based performance enablers:
Data transfer rate, maximum I/O transfer size, command queuing
Throughput rates are heavily dependent on the internal controller bandwidth
Maximum throughput rates can typically be reached with a small number of disk drives
SATA delivers about 66% of SAS’s drive-level performance FC

Revisiting our application access patterns table, and factoring in what we’ve learned about SAS and SATA drives, we’ll be able to figure out which drives are best suited for various application based on their typical data access patterns.
For IOPS applications with I/O intensive, random access workloads, FC drives are far and away the best choice.
For bandwidth applications with throughput intensive, sequential access workloads, SATA drives are often an acceptable option.

Beware, this is “best case.” In the real world, unless you have dedicated infrastructure,
you will find somewhat slower IOPS, due to iSCSI network contention.
