FlashCopy

A point-in-time (PiT) image of a logical drive / LUN• Logical equivalent of a physical copy

Features• Near instantaneous copy• Requires less disk space than a full copy• Can be mapped to any host • Can be read from, or written to

Primary uses• PiT backup image• File / volume restoration• Data mining / analysis

Advantages• Created nearly instantaneously• Space efficient

− Default is 20% size of the original Disadvantages

• Pointers to original data set− Rely on original data being available

• Can impact performance

Volume Copy

Complete (byte-by-byte) PiT replication of one logical drive (source) to another (target) within a storage system

• Target also referred to as a clone Primary uses

• Full PiT data set available for analysis, mining, testing, backup

• Helps eliminate I/O contention on the primary logical drive

Online Volume Copy• Volume copy with integrated FlashCopy• Eliminates “read-only” copy restriction• FlashCopy created as part of operation• Must have FlashCopy premium feature

Production Server Analysis Server

IBM System Storage


VolumeCopy Implementation

Step 1 Step 2

Volume copy with integrated FlashCopy

– Eliminates “read-only” copy restriction

– FlashCopy created as part of operation

– Must have FlashCopy premium feature

FlashCopies created as part of operation have “ONC” prefix

“ONC” FlashCopies have restrictions

– Cannot be disabled/recreated etc.

Operation integrated into GUI

Enhanced Remote Mirroring

Storage-based data replication–

Ongoing, real-time replication of a logical drive from one DS5000

storage subsystem to another

Three mirroring modes–

Metro Mirror - Synch Mode

–Global Copy - Asynch Mode

–Global Mirror - Asynch Mode

Primary uses–

Disaster recovery

–Centralize backup data

–Centralize data mining / analysis

•Número de pares de volumes depende do equipamento

Metro Mirror 10KM

Global Mirror >>10 KM

IBM System Storage


Como funciona Metro Mirror na série DS5000/DS3500 ?

Modalidade síncrona Durante a ativação do ERM, é criado um Mirror Repository Volume para cada controladora

• Possui metadata de controle do espelhamento de dados (2b) ocorre se o volume primário não tiver write cache enable Metro Mirror adiciona latência na operação de Write do aplicativo ERM suportado até 10KM

Parte III• Novidades de 04/Junho/2012 no DS3500

IBM System Storage


Novo firmware 7.83 anunciado em 4 de Junho 2012

Resumo das melhorias

Introduz os conceitos de:• FlashCopy Consistency Group• PiT Group

Thin Provisioning – O volume lógico agora pode ser TP

Dynamic Disk Pooling• maior performance no back-end

Suporte de APIs do VMware (vStorage APIs for Array Integration)

IBM System Storage


Dynamic Disk Pooling – o que é ?

Novo tipo de Array onde o Volume Lógico é espalhado pelo Pool

Podemos adicionar discos ao pool para crescimento do pool

• Dados são redistribuidos automaticamente

Não existe disco hot spare dedicado

• Existe uma capacidade reservada no Pool (capacity spare)

• Na falha de um disco, seus segmentos são reconstruidos pelos demais discos em operação

DS3500 suporta co-existencia de DDP com RAID tradicional

Decouple physical storage allocation from provisioningAllocate small, initial amount of storagePull needed storage from pool at the time it is needed

Manage storage pool as a resource independent of volumes

Share free space across all applications Grow or shrink volumes non-disruptively

Simplify Storage and Data ManagementAutomate storage provisioningEliminate impact of administrator uncertainty when sizing volumes

Upgrading DS3000/DS5000 code

Consider risk of doing concurrent upgrade

–Single paths?

–OS configured for multipathing?

–SAN zoning?

Consider reasons why you need to upgrade?

–Stay current•

BUT - Don’t upgrade just to upgrade

Consider host code

–Drivers

–HBAs

–Operating system patches

IBM System Storage


Upgrading DS5000

Things that will need upgrading

Storage Server–

NVSRAM

–Controller FW

•FW and NVSRAM are always installed as a pair

•They provide the brains of the DS5000 storage server

–ESM

–Drive micro code – noncurrent

Host System–

RDAC(MPP) or MPIO

–HBA code and driver

NVSRAM contém

Controller Firmware Upgrade Utility

A stand alone utility

Used to check the DS health, and its eligibility to be upgraded

Helps to ensure that any disk system selected for upgrade:

–Is at supported levels of hardware and controller firmware

–Has no existing conditions that may prevent the upgrade from completing successfully

–Has its configuration and MEL saved prior to upgrade for later use if required

–Is offline for the minimum amount of time possible

Run from any machine that has a management connection (in or out of band)

Note: SM 10.10 upgrade is an offline process

MEL: Major Event Log
