ACSG News November 2015
Sehr geehrte Kunden,
IBM hat kürzlich die IBM Spectrum Virtualize Release 7.6 mit Verfügbarkeit ab 27.
November für Software und 18. Dezember d. J. für Hardware angekündigt.
Die IBM Spectrum Virtualize Software wird mit dem/den



IBM SVC Storage Virtual Controller
IBM Storwize Systemen
IBM FlashSystem V9000
mitgeliefert.
Die neuen Funktionen sind

Die Verschlüsselung des virtualisierten externen Speichers
wird auf dem IBM SVC DH8, der Storwize V7000 und dem FlashSystem V9000
unterstützt. Dieses geschieht als "Data at rest", d. h. die Daten werden direkt
auf den Plattenlaufwerken verschlüsselt, mit minimalem Einfluss auf die
Performance.

Distributed RAID 6
Im Gegensatz zum traditionellen RAID6 mit doppelter Parität werden die
Daten über bis zu 128 Laufwerke verteilt. Im Rebuild-Fall sind alle
Laufwerke beteiligt, was einen enormen Geschwindigkeits-Vorteil mit
sich bringt, insbesondere bei Platten mit hoher Kapazität. Weiterhin
erbringen alle Laufwerke ihren Anteil an der Gesamt-Performance,
insbesondere bei Einsatz von Flash-Laufwerken.

HyperSwap und Stretched Cluster Erweiterungen
Ein erweiterter GUI-Support mit starker Vereinfachung der Bedienung,
auch für das Command Line Interface, ist hierfür einsetzbar.
Das Quorum ist bei IBM Spectrum Virtualize notwendig um Situationen
zu vermeiden, in denen die Clusterkomponenten die Verbindung
verlieren. Für Stretched Cluster und HyperSwap war bisher am dritten
Standort die Kommunikation über Fiber Channel notwendig.
Mit dem neuen Release steht eine Java App mit IP Verbindung zur
Verfügung, die Fiber Network und Fiber Storage eliminieren kann.

Intergrierter Comprestinator
Dieses Tool ermittelt den Grad an Komprimierung von Daten, die von den
verschiedenen Server Applikationen stammen. Das Tool ist jetzt Bestandteil
des IBM Spectrum Virtualize 7.6 Code und somit auf den vorgenannten IBM
Systemen integriert verfügbar.
Somit werden Anwender in die Lage versetzt, aus dem System heraus
unterbrechungsfrei in kurzer Zeit die prozentuale Ersparnis von Speicherplatz
zu ermitteln.

4 Port 16 Gbs Fiber Adapter
Diese sind für den IBM SVC DH8, IBM Storwize V7000 Gen. 2 sowie
IBM FlashSystem V9000 lieferbar. Das bedeutet für den SVC ein einem
8 Node Cluster bis zu 128 Ports á 16 Gbs und für die V7000 bzw.
V9000 bis zu 16 Ports á 16 Gbs pro System mit Auto Negotiation 8 /16
Gbs.
Die anliegenden Präsentationsfolien enthalten die Details zu den oben genannten
Kurz-Beschreibungen.
Für Fragen, weitergehende Informationen und Vorschläge bzw. Angebote stehen wir
Ihnen zur Verfügung.
Wir freuen uns auf Ihren Anruf oder eine Email.

Encryption for External Virtualized Storage
• New capability enables encryption of virtualized storage
– Helps to improve data security
– Eliminates need to purchase new storage systems or drives to enable encryption
– Provides single point of administration for encryption across multiple heterogeneous storage systems
• Supported on SVC DH8 engines, Storwize V7000 Gen2, FlashSystem V9000
• Takes advantage of Intel AES-NI processor instructions to perform encryption
– Minimal impact on performance

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
© Copyright IBM Corporation 2015
3
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 drives
o Drives returned to vendor as part of maintenance actions
– Secure erasure of storage
o Drives or arrays being reused for different data
o 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
© Copyright IBM Corporation 2015

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

Using External Storage Encryption
Volumes Striped
• 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 them

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

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)

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
© Copyright IBM Corporation 2015
✗
9
Distributed RAID 6
• 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
© Copyright IBM Corporation 2015
Distribute 3+P+Q over 10 drives with 2 distributed spares
10
Additional Distributed RAID Benefits
• 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

– Includes flash drives with SVC
•
•
•
•
Supports distributed RAID 5 and 6
Up to 128 drives in an array including up to 4 spares
Up to 10 arrays in an I/O Group, 32 per clustered system

IP Quorum
• 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

•
•
•
•
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

18
Integrated Comprestimator
• Comprestimator now integrated as part of IBM Spectrum Virtualize 7.6 code
