5Virtual disks Hosts are still mapped to LUNs that they believe are physical disks – but are really Virtual disks that are created with the capacity and quality of service required by the application

Virtual-to-physical Mapping The SAN Volume Controller controls the mapping of Virtual disks to Managed disks

High Perf Low EndManaged disks are collected into Managed Disk Groups to facilitate different categories of storage devices

The SVC “insulates”the host systems from the effects of changes in the physical environment so disk subystems can be

moved in and out and copy services can span dissimilar subsystems


Storwize V7000 Overview

Efficiency Features

Thin provisioning�More productive use of available storage

�Works across all supported host platforms

and all supported external storage systems

Without thin provisioning, pre-allocated

space is reserved whether the application

uses it or not.

With thin provisioning, applications can

grow dynamically, but only consume space

they are actually using.

Initial Setup

� Initial Setup - Initialization Tool – Small application on USB key (based on MS Windows)– Initialization Tool ask for:

•Cluster IP address•Subnet Mask•Network Gateway

– Initialization Tool create a small file in the same directory

– Example file: – satask mkcluster -clusterip 9.166.66.66 -gw 9.166.66.1 -mask 255.255.254.0– Plug in the USB key in the new V7000 system– IBM Storwize V7000 will:

•Automatically execute the file•Delete the file after execution•Write a response file (html) to the USB Key

– The named procedure protects the customer against•Accidential cluster creation (file is only available one time)•Unexpected activities because of a disremebered USB key (file is not available anymore)•Unexpected cluster creation (cluster will not allow a Cluster create, if there is already a Cluster configured)•...

Node Enclosure 1

� SAS cabling rules:– Each Node Canister has two SAS ports which will be

numbered 1 and 2– No more than 5 expansion enclosures can be

chained to port 1 on the node canisters– No more than 4 expansion enclosures can be

chained to port 2 on the node canisters– The list of enclosures attached to each node canister

port 1 must match (same rule for port 2)– The list of enclosures attached to any given port

must be connected in the same order


FC Arbitrated Loop vs. SAS Controllers and Expanders

� FC: loop technology (history)– Adding or removing a device from

the loop causes all activity on the loop to be interrupted

� FC disks are expensive

� Physical adapters are required for SATA and SAS disk drives

� Max. 127 disk devices per loop

Via SAS Expander

� SAS expander: switch technology– point to point connection to every drive in

the enclosure– improving the ability to locate and fix disk

failures

� SAS disks are inexpensive

� SAS and SATA disks direct pluggable – general trend to 2,5” disk drives with SAS

interface

� Max. 255 device port expanders (>65k total devices)


News with 6.4 code

� FCoE Support

� Compression

� FC Direct Attach


Real-time Compression – 45 Day Trial License

� 45 Day Free Trial License of Compression Function– Included in software so simply activate using the GUI by setting to something other then

zero to avoid errors in event log


Expected Compression Rates

� IBM Comprestimator tool should be used to evaluate expected compression benefits in existing environments


Compression Implementation Guidelines

� Compression performance –– Performance of thin provisioned volumes (supported by the same number of HDDs) with and without compression is roughly

equivalent

� Use Comprestimator to identify workloads that are go od candidates for compression– More than 45% savings – recommend to compress – Between 25-45% savings – recommend evaluating workload with compression– Less than 25% savings – recommend avoiding compression

� Common workloads suitable for compression– Databases – DB2, Oracle, MS-SQL, etc.– Applications based on databases – SAP, Oracle Applications, etc.– Server Virtualization – KVM, VMware, Hyper-V, etc.– Other compressible workloads – engineering, seismic, collaboration, etc.

� Common workloads NOT suitable for compression– Workloads using pre-compressed data types such as video, images, audio, etc.– Workloads using encrypted data– Heavy sequential write oriented workloads– Other workloads using incompressible data or data with low compression rate
