#ibmedge

History of Flash Memory

Read-Only Memory (ROM)• Hardwired at the factory• Cannot be erased or re-written• Used for “boot programs” and BIOS• Embedded mass-produced systems

Programmable ROM (PROM)• Manufactured as blank

memory• Can be written only

once, with PROM burner device

Erasable PROM (EPROM) • “firmware”• reusable, erased by Ultra-

Violet (UV) light• Written using an external

EPROM burner device

Electrically Erasable PROM (EEPROM)• reusable, erase and

write bytes using voltage levels in place on circuit board

• No need to use burner

Why NAND instead of NOR technology?• Offers higher densities, larger capacities,

and lower cost • Faster erases, sequential writes, and

sequential reads• Best suited to systems requiring high

capacity data storage

NOR Flash• Erase blocks• Write bytes

NAND Flash• Erase blocks• Write pages

Data Scrubbing

Over time, electron charge of the cell decays, shifting everything to the left

Data scrubber reads data over the course of days or weeks to predict uncorrectable errors

At-risk data is read, corrected, and written to new pages while still correctable

Dynamic Read Voltage Shifting

While scrubbing, IBM controller performs real-time analysis to determine read voltage

With Dynamic Read Voltage Shifting, thresholds track decaying charge

Error rates appear unchanged from their original post-programming values

Error Detection and Correction Codes (ECC)

Bose Chaudhuri Hocquenghem (BCH)A class of cyclic error-correcting codes that are constructed using finite fields. BCH codes can correct multiple bit errors with a simple algebraic method that can be implemented with low latency (fast)

Low-Density Parity Check (LDPC)A powerful ECC algorithm that dates back to the 1960s. It is computationally intensive and has higher latency (slower)

IBM Error Correcting CodeAn innovative algorithm that provides fast, low latency similar to BCH codes, but is able to correct more multiple bit errors similar to LDPC

14

#ibmedge

IBM FlashCore – Advanced Flash Management

The bit error rate (BER) is the number of bit errors per unit time. It increases as more P/E cycles occur to the Flash chip

Standard MLC

IBM ECC increases the bit error rate tolerance, allowing more P/E cycles

IBM Heat Segregation, Health Binning, Dynamic Read Voltage Shifting improves Write Endurance

Combined benefit 9.4x Endurance

Database Compression

Use Database Compression when

• Fastest performance is required

• Lowest price/performance is a priority

• Workload primarily contains moderate to heavy sequential writes

StorageCompression

Use Storage Compression when

• Primary focus is quantity of storage consumed

• Minimize server CPU

• The workload is primarily random I/O:

– OLTP Databases

– Server Virtualization

– Virtual Desktop Infrastructure (VDI)

– Collaboration

– Engineering, Seismic, CAD/CAM

•Plenty of non-database data also compressed

When Should Clients Use Database Compression vs. Storage Compression?

Advantages

Compressed data is read as is into DRAM memory

• More records per I/O request

• Faster full-database scans

• Reduced SAN traffic

Compressed data consumes less storage space

• Typically reduces database disk requirements by 60% (2.5 x)

• Improves economics for Flash and SSD

Disadvantages

Compression consumes more CPU resources

• May increase your per-core software licenses to database vendor

• May increase number of servers needed to handle your business workload

• Slower INSERT and UPDATE of individual rows

Does not compress other types of data

• 80% of your data is unstructured content outside of databases

Advantages

Compressed data consumes less storage space

� Typically reduces database disk requirements by 80% (5x)

� Improves economics for Flash and SSD

Does not consume server CPU resources

Compress all types of data

� Not just your database tables and indexes

Disadvantages

Uncompressed data read into DRAM

� Does not reduce memory requirements for database

� Does not reduce SAN traffic

Consumes more storage CPU resources

� May impact I/O operations of other applications

� May reduce total IOPS and throughput capability of the storage device

#ibmedge

Conventional Wisdom Holds – Do Not Compress Compressed Data Except In Very Specific Situations

• Turned on both database and storage compression

• Results

• Performance much lower than DB2 compression and even lower than uncompressed

• Price of transactions greatly increased

• Even a DB2 database with deep compression may have large amounts of free space interspersed between segments of compressed data.

• This is done for performance reasons and in this scenario it might make sense to use both types of compression at the same time.

Therefore, no assurance can be given that an individual user will achieve throughput or performance improvements equivalent to the ratios stated here.
