– Minimal impact on performance

• Available worldwide except– Belarus– Kazakhstan– People's Republic of China– Russia

Encryption for External Virtualized Storage

5


Encryption Basics

• Encryption is the process of encoding data so that only authorized parties can read it• Uses secret keys to encode the data according to well known algorithms• “Data at rest” means the data is encrypted on the end device • Algorithm being used is AES: US government standard from 2001• Algorithm is public, the only secrets are the keys• Symmetric key algorithm (same key used to encrypt and decrypt data)

Importance of encryption• Improves physical security of data• Required by certain customers• Allows customers to send failed hardware back to IBM under warranty

6


Encryption Use Cases

• Encryption typically of interest to industries with high privacy concerns– Financial services– Healthcare– Any client concerned about possible disclosure of data

• Typical encryption use cases– Protection against disclosure of data when drives removed

o Malicious removal of driveso Drives returned to vendor as part of maintenance actions

– Secure erasure of storageo Drives or arrays being reused for different datao System being sold or otherwise disposed of

• IBM Spectrum Virtualize encryption addresses all these use cases• Encryption helps protect against disclosure as a result of access to drives storing data

– Does not address other exposure such as unauthorized access to systems

7


When is Data Encrypted/Decrypted

• Data is encrypted/decrypted when it is written to/read from external storage– Encryption/decryption performed in software using Intel AES-NI instructions

• Data is stored encrypted in storage systems• Data is encrypted when transferred across SAN between IBM Spectrum Virtualize system

and external storage• Data is not encrypted when transferred on SAN interfaces in other circumstances

– Intra-system communication for clustered systems– Remote mirror– Server connections

• If appropriate, consider alternative encryption for “on the fly” data

8


Using External Storage Encryption

• External encryption is enabled at the storage pool level

• Storage pools contain multiple mdisks• Volumes are usually striped across mdisks in a

storage pool• With Easy Tier, volumes migrate among mdisks in a

pool• All volumes created in an encrypted pool are

automatically encrypted• Volumes may be moved or copied between pools of

different types• Mdisks being encrypted by the storage system can be

identified: IBM Spectrum Virtualize won’t encrypt them9

Volumes Striped

Encrypted by storage system


Implementing Encryption

• Create new encrypted pool• For existing data, move volumes from existing pool to new pool• No “convert in place” function to encrypt existing pools• May require additional capacity

10

Unencrypted Pool Encrypted Pool


Encryption Key Management

• IBM Spectrum Virtualize has built-in key management• Two types of keys

– Master key (one per system)– Data encryption key (one per encrypted pool)

• Master key is created when encryption enabled– Stored on USB devices– Required to use a system with encryption enabled– Required on boot, stored in volatile memory on system– May be changed

• Data encryption key is used to encrypt data and is created automatically when an encrypted pool is created– Stored encrypted with the master key– No way to view data encryption key– Cannot be changed– Discarded when an array is deleted (secure erase)

11


Encryption Statements of Direction

• IBM intends to extend support for encryption on Storwize V7000 to include externally virtualized storage

• IBM intends to implement encryption on SAN Volume Controller to include externally virtualized storage and SAS attached storage (including flash drives) in the expansion enclosures

• IBM intends to enhance encryption on Storwize V7000 and SAN Volume Controller to include support of IBM Security Key Life Cycle Manager as an option for managing encryption keys

• IBM intends to extend support for encryption to included file storage on Storwize V7000 Unified

Ordering Encryption

13


Traditional RAID 6

• Double parity improves data availability by protecting against single or double drive failure in an array

However …

• Spare drives are idle and cannot contribute to performance– Particularly an issue with flash drives

• Rebuild limited by throughput of single drive– Longer rebuild time with larger drives– Potentially exposes data to risk of dual failure

14

✗


• Spare capacity, not spare drives• Rotating spare capacity position distributes

rebuild load across all drives• More drives participate in the rebuild

– Bottleneck of one drive is removed• More drives means faster rebuild

– 5-10x faster than traditional RAID– Especially important when using large drives

• No “idle” drives– All drives contribute to performance– Especially important when using flash drives

Distributed RAID 6

15

Distribute 3+P+Q over 10 drives with 2 distributed spares


• Improved performance during sequential write streams due to distributing the writes over more drives– Particularly important while rebuilding

• Maximum re-use of existing RAID code– Majority of changes are outside the existing proven I/O path

21


• Quorum disk (also called “witness” in some other implementations) is required with IBM Spectrum Virtualize to resolve situations where cluster components lose communication

• For Stretched Cluster and HyperSwap, this has required fibre channel communications to a third site, which adds to cost

• New IBM Spectrum Virtualize capability creates custom Java app for quorum– Deploy app on server at third location– Use IP connectivity to cluster components– Eliminates requirement for FC networking and FC storage at third site

“Virtual Volumes are a new integration and management framework that virtualizes SAN/NAS arrays, enabling a more efficient operational model that is optimized for virtualized

environments and centered on the application instead of the infrastructure.”- VMware

But essentially…:

Virtual Volume = IBM Spectrum Virtualize Volume

1x Virtual Machine = 3x VVOLs (…at least)

1x VM Metadata VVOL = 4GB1x Swap VVOL = Same size as VM Memory1x VM Operating System VVOLAdvantages:

Automation - VVOLs are created/deleted automatically when required

Hardware acceleration - Off-loading snapshot and cloning functionality to the storage level

Policy Based Storage Management - To aid storage provisioning

Granularity - More granular visibility, isolation and adjustment of VM storage.

No shared storage - 1-to-1 mapping of VM’s drives to IBM Spectrum Virtualize Volumes.

What are VMware Virtual Volumes?

23


vSphere VVOLs Overview

• Uses same mechanism as VASA 1.0 and introduces VASA 2.0 APIs

• 2-way communication between vCenter and IBM Spectrum Virtualize, via IBM Spectrum Control Base Edition

• As VMs are created, VASA issues mkvdisk commands to IBM Spectrum Virtualize

• VASA APIs are over IP via SSH CLI commands - Virtual Machine IO is via Protocol Endpoints (PE)

24


IBM Spectrum Control Base Edition

• Linux Application with Web UI - Installed on VM/Physical/Both

• vWC Allows remote control of IBM Spectrum Virtualize from within vCenter UI– Single pane of glass & can simplify SVC tasks.

• Storage Capabilities defined for Policy-Based Management

• Storage Admin can allocate storage with pools• Child Pools are mounted as VVOL Datastores

in vCenter• In vCenter, VM tasks trigger IBM Spectrum

Control Base Edition to issue the relative commands to IBM Spectrum Virtualize

25


What do you need for VVols?

Requirements• vSphere 6.0 installation

– Both vCenter and ESXi Servers• VASA Provider for IBM Spectrum Virtualize

– Requires IBM Spectrum Control Base v2.2 installation• System running IBM Spectrum Virtualize 7.6

26


• Tool used to estimate benefits of Real-time Compression• Minimal impact system load, fast, accurate• Free to download from IBM website• External (host based) CLI tool

– Some clients do not want to have to run a tool on their servers• Supports data on any storage system

What is Comprestimator

27


• Comprestimator now integrated as part of IBM Spectrum Virtualize 7.6 code– CLI only– Does not require compression license– Does not start RACE (RtC compression engine) – saves resources for host IO

• Enables compression estimates for data stored on systems based on IBM Spectrum Virtualize– No need to install software on servers

• Same algorithm as host based tool (so same results are expected)• Keeps host I/O uninterrupted • Minimal impact system load, fast, accurate

– Usually <1 minute per volume, could be longer on loaded system• <5% error margin (same as stand-alone tool)

Integrated Comprestimator
