protecting, storing and maintaining encryption keys that are used to encrypt information

being written to and decrypt information being read from storagemedia.

�TKLM executes in the IBM Java run time environment and it uses IBM Java security

components for the cryptographic capabilities used.

Solid State Drives



13What are Solid State Drives?

�Not Magnetic

�Not Optical

�Semiconductor (NAND flash)

–Electronically erasable medium

–Random access

–No mechanical read/write interface

(arm

/head)

–No rotating parts

�Packaged with interface just like HDD

and function just like HDD



14

SSD Reliability, Power, Heat

�Absence of mechanical moving parts

–Significantly more reliable

•Used in military applications

•Used in extreme temperatures (hot/cold)

�Green

–Power

•Fraction of power consumed

–Heat

•Fraction of heat dissipated



15SSD Endurance

�Flash program/erase cycles are cumulatively destructive

�Current commercial NAND flash varieties

–Single level cell (SLC) �

105 writes/cell (our SSD is SLC)

–Multi level cell (M

LC) �

[ [[[104 writes/cell (Cameras, iPods,

etc.)

�Coping strategies

–Wear leveling, over-provisioning, bad block m

anagement, ECC,

compression, write elim

ination, …

�Data stored remain valid for 10 yr without power

SSD Recommended Use

�Best suited for cache-unfriendly data

–Random read access, high perform

ance data sets

•Both FB and CKD environments



27SSD Awareness

�SMS volume selection will recognize volumes backed by SSD

–Policies implemented by ACS routines can direct allocations to SSD

•Consider using a Storage Group with only SSD

�New fields for SMF type 42 subtype 5 and 6 records

•Average read disconnect time per data set

•Total number of read operations to the data set

SATA 1TB disks



3030

1 TB SATA 7200 RPM Drive Support

�New 1 TB SATA drives will become

available on March 6, 2009

�Enabled through new feature code

specifications in megapack(16)

drive increments (see following

chart for list of feature codes)

�Scales DS8000 to 1,024 TB physical

capacity when fully populated with

all 1 TB SATA drives (5 frames)

�All models of the DS8000 family are

supported (2107, 2421, 2422, 2423

and 2424)



3131

When to Consider SATA

�Tier-1 Storage

–When looking for low cost per gigabyte with lower expectations of

perform

ance

–Streaming applications where transfer rate is m

ore important than

seek times

–Applications with low IOPS perform

ance requirements

�Tier-2 Storage

–Disk based near-line storage between disk and tape

–Disaster recovery target for remote replication

–Fixed content / Managed Retention data

–Temporary work space for short-term

processing

–Consolidation of tier-2 subsystems



3232

SATA Drive Requirements and Limitations

�1 TB SATA drives will require at a minimum licensed machine code

(LMC) level 5.4.2xx.xxx (bundle version 64.2.xx.xx)

�Only RAID-6 or RAID-10 will support the SATA drives

–No RAID-5 support at GA

–RPQsfor RAID-5 support m

ust be submitted through norm

al

channels

–RAID-6 requires DA-2 device adapters

�Not intended for Space Efficient FlashCopyrepository because of

the lower performance and reliability characteristics

�A SATA drive will not be used as a spare for FC or FATA drives

–Perform

ance of the entire array would be degraded



3333

SATA Design Architecture

�SATA architecture uses a 512 byte physical sector size

�DS8000 device adapters require 524 bytes sector size

�SATA uses a different protocol compared to fibrechannel

�IBM elected to utilize a bridge card

•Translates fibre

channel protocol to SATA protocol and vice

versa

•Bridge card is an EmulexBRG436-I

•Connects to Hitachi Gemini-K 1 TB SATA drive

•Requires padding to align blocks to sector size

•Each SATA drive has its own dedicated bridge card

Sector Mapping Capacity Tradeoff

�Reduced disk capacity due to extra padding added

on every alignment unit. The estimated loss of

disk capacity is as follows:

–128 block alignment –0% capacity loss

–64 block alignment –0.76% capacity loss




�DS8000 will utilize a 8/9 sector remapping

–Every 524 byte block aligns at 512 byte sector

boundary on every 8 logical blocks due to padding

3838Sector Remapping

�Higher performance (8/9) remapping was chosen

over higher capacity (128/131).

�Results in significantly higher write performance

�However 1 TB SATA drives will have about 900 GB

of usable capacity

�Formatted arrays are quite large

4444Intermix of 1 TB SATA Drives

Intermix of 1 TB SATA Drives

�The same rules governing intermix of FibreChannel

and FATA drives apply to SATA drives

�Intermix of FibreChannel, FATA or SATA drives on the

same DA pair is allowed.

�1 TB SATA drive can not be used as a spare in the

event of a failure of FC or FATA drive

�If a spare occurs, the rank will take on the attributes of

the slowest drive in the rank (no change in how this

operates)

�Neither FibreChannel nor FATA drive can serve as a

spare for the 1 TB SATA drives due to their smaller size

5656IBM Remote Pair FlashCopy-Requirements

�Remote pairs must be in Full Duplex state

–Source and Target are Metro Mirror Pairs

�Secondary of FLC source and target are in the

same subsystem

–For best perform

ance they should be in the same

cluster as well

�Local or remote targets may not be Space Efficient

volumes

�No cascading configurations MGM / MGC (target

volumes)

High Perform

ance FICON for System z (zHPF)

DS8000 can double the throughput for System z environments

•High Performance FICON for System z can double data throughput

–I/Os per second can increase by up to 100% for small data transfers of OLTP and other workloads

–Large sequential workloads of both read and write operations canalso show great perform

ance

improvement

–Pricing is a one-time charge of $10,000 for any DS8000 system looking to exploit zHPF

•Requires IBM DS8000 Release 4.1, System z10 and z/OS 1.8 and higher with PTF

–Supported on FICON Express2 and FICON Express4

* Some complex channel programs can not be converted to zHPF protocol
