4. Storage Challenges Challenge # 1: Rapid Capacity Growth
Storage will continue to grow
How to handle?
More people or manage storage more efficiently
Challenge # 2: Poor Storage Utilization
Typical storage utilization rates 25 – 40%
Over-provisioning
Occurs due to fear of running out of space
Applications not knowing what they really need
Challenge # 3: Tiered Storage
Hardware tiering to reduce cost of where data rest
Value of data decays over time
Storage Administrators forced to redistribute data
11/20/2018

5. Storage Challenges (continued)
Challenge # 4: Non-Disruptive Data Migration
Expectation zero downtime – impacts applications
Technology refreshes
Vendor/Equipment swap outs
Routine maintenance
Configuration activities
Challenge # 5: Data Protection & Disaster Recovery
High level of administrative complexity
Protect each application and its data
Cope with a variety storage array vendors and products
Deal with data consistency issues

6. Overall Benefits Benefit #1: Heterogeneous Storage Pools
Can manage unlike storage vendors as one entity
Eliminates buying additional frames due to better utilization of installed base
Benefit #2: Central Control Point for All Storage Devices
Reduce Storage Management complexities
Benefit #3: Tiered Storage
Establish means to deploy tier storage methodologies
Benefit #4: Non-Disruptive Data Migration
Ease of data migrations once within SVC

7. Before Virtualization
Islands of servers and storage
Poor asset utilization
Too much power/cooling/space
Performance and reliability issues
Data recovery can take days
Provisioning can take weeks
Slow test/development processes
Complex and costly DR
Why Virtualization?
Improve Flexibility with the storage infrastructure with virtualization

8. Green Storage Management

9. Green Storage Management
Green Storage Management is about
Manage storage to use the least possible power
Balancing I/O to reduce peak access densities
Reduce I/O rates to disk to facilitate use of High Capacity Drives (300GB)
Things to consider:
Compression saves cycles and storage
Striping helps to smooth peak loads to volumes
Defrag generates a lot of I/Os but may not be needed
Space Efficient Fast Internal Copy provides major savings
Virtualization
11/20/2018

10. Things to Consider Continued
Faster drives use more power
Larger Drives with more platters use more power
Power and Cooling costs
Efficient Storage or Efficient Access?
Doubling the HDD size and move 10K to 15K RPM drives
Better performance at low load
Lower maximum throughput
For 73GB 10 k RPM to 146 GB 15 k RPM
Saves about 30 % in HDD power requirements
For 146GB 10 k RPM to 300 GB 15 k RPM
Saves about 25 % in HDD power requirements
11/20/2018

11. Storing or Accessing Data Affects Energy
Energy cost for data storage can be expressed in Watt /Gbyte
Higher Capacity drives will be more efficient
Slower drives will be more efficient
FATA uses less power per Gbyte than Fibre does
Fibre Channel ATA FATA is a hybrid hard drive first introduced by HP in 2004 that combines both Fibre Channel and ATA technologies. FATA drives use an ATA drive mechanism, offering the same performance and capacity as a standard ATA drive, but also feature a Fibre Channel connector, which enables the FATA drive to be used where conventional Fibre Channel drives are currently connected.
Relevant for tape-replacement (sequential) workloads
Energy cost to do I/Os can be expressed in kWh / 1000 I/Os
Faster drives are more efficient per I/O
Fibre uses less power per I/O than FATA does
Relevant for data base workloads

12. RAID choices are very important
RAID 10: 4 data disks, 4 ‘parity’ disks in group of 8 drives
100% drive and power overhead for protection
RAID 5: 7 data disks, 1 parity disks in group of 8 drives
14% drive and power overhead for protection
RAID 5 is more efficient: 75% more data on same # of drives
RAID 10 and RAID 5 read records the same way!
RAID arrays are used in back-end of cached disk subsystems
Only read-misses need to be resolved during I/O operation
All writes are handled asynchronously; write inefficiencies
are a second order effect
RAID 10 subsystem will have more ‘arms’ per Gbyte stored,
so for a given capacity it can perform more I/Os per second
11/20/2018

13. RAID 10 vs RAID 5 Subsystems
Consider two 20 Tbyte (user capacity) subsystems:
RAID 10 with 274 drives (146 GByte each)
RAID 5 with 158 drives (146 GByte each)
RAID 10 subsystem will use more power
RAID 10 subsystem has more drives to do work (I/Os)
RAID 10 subsystem will support higher access density
So you should compare:
RAID 10 with 134 drives (300 GByte each)
RAID 5 with 158 drives (146 GByte each)
Reduce HDD count and move 10k to 15k RPM drives
Better performance at low load
Lower maximum throughput (fewer drives)
11/20/2018

14. Write Considerations Random writes are more efficient with RAID 10
Sequential writes are more efficient with RAID 5
As long as back-end can handle all writes, writes will be asynchronous and have no direct impact on (read) response time.

15. Thin Provisioning

16. Thin Provisioning Definition:
Thin provisioning is a mechanism that applies to large-scale centralized computer disk storage systems, SANs, and storage virtualization systems.
Storage consolidation environment
many applications are sharing access to the same storage array,
thin provisioning allows administrators to maintain a single free space buffer pool to service the data growth requirements of all applications.
Avoids the poor utilization rates, often as low as 10%, that occur on traditional storage arrays where large pools of storage capacity are allocated to individual applications, but remain unused (i.e. not written to). This traditional model is often called fat provisioning.
Allows storage capacity utilization efficiency
Can be automatically driven up towards 100%, without heavy administrative overhead
Organizations can purchase less storage capacity up front
Defer storage capacity upgrades in line with actual business usage
Save the operating costs (electricity and floorspace) associated with keeping unused disk capacity spinning
Previous systems generally required large amounts of storage to be pre-allocated
Thin provisioning enables over-allocation or over-subscription
Over-allocation or over-subscription is a mechanism that allows server applications to be allocated more storage capacity than has been physically reserved on the storage array itself
Allows flexibility in growth and shrinkage of application storage volumes, without having to predict accurately how much a volume will grow or contract.
Physical storage capacity on the array is only dedicated when data is actually written by the application, not when the storage volume is initially allocated
