IBM Storwize V7000 and Storwize V7000 Unified storage system
In today’s storage management, breaking the cycle of increased complexity and explosive data
growth can be a big challenge. The old ways of buying and managing storage have become less
effective. Due to resource constraints in both physical storage resources and human resources, IT
organizations must act quickly to optimize and simplify their infrastructure. Unchecked complexity and
growth can only become bigger problems over time.
To stand up to these challenges and allow businesses to respond to a rapidly changing marketplace,

Riverbed Steelhead EX + Granite
Riverbed Granite solution enables users and applications in branch office locations to write to and
access centrally managed storage while maintaining local disk performance. Riverbed Granite
solution enables faster branch access to data center deployed SANs, and it effectively eliminates the
IT organization’s need to provision and maintain dedicated storage resources in branch offices.
The Riverbed Granite solution is deployed in conjunction with Riverbed Steelhead appliances and
consists of two components:
•
•
Granite Core – A physical or virtual appliance that resides in the data center
alongside centralized storage
Granite Edge – A module that runs on a Steelhead EX appliance in the branch office
Granite Core mounts iSCSI logical unit numbers (LUNs) provisioned in the data center and shares
the storage resources with branch offices running the Granite Edge module. Granite Edge virtually
presents one or more iSCSI targets in the branch, which can be utilized by services and systems
running both within the Riverbed Virtual Services Platform (VSP) and externally to the Steelhead EX
appliance. Granite Core inspects mounted file systems and is able to proactively stream data to the
branch. This capability allows data from centralized storage to be available wherever and whenever it
Branch office enablement solution with IBM storage systems and Riverbed Granite technologies

is needed. Through asynchronous block-based write acceleration, Granite Edge ensures that data
created in branch office locations is securely stored in the data center.
Figure 3: Granite Core and Granite Edge high-level network topology
Use case: Branch office file server with Steelhead EX + Granite
A typical use case for file server implementation in a branch office environment using Steelhead EX +
Granite appliances is when a customer has to perform file sharing at many remote sites and wants to
have local performance, 100% uptime even during WAN outages, and wants to constantly protect the
data at a centralized location in case of disaster at any of the branch offices. The ability to centrally
provision new file servers and new file shares, and centrally perform regular backups and centrally
monitor the overall infrastructure is also an important aspect of this use case.

Key solution benefits
The key solution benefits are as follows.
•
Enable consolidation: Data is consolidated in the data center where backup can be done
centrally and where skilled IT storage personnel resides and can manage and configure the
storage. This eliminates the need for data backup or replication software and hardware in the
branch. In case of a disaster, data can be streamed quickly, resuming operation in the order of
minutes. For durability and optimization, Storwize V7000 and SAN technology enables
consolidation and virtualization of storage in the data center. High availability of the data is
achieved through features such as IBM FlashCopy® backups, Metro Mirror, and Global Mirror
disaster recovery features in the data center. Third-party storage already existing in the data
center can be reused and further optimized through Storwize V7000 and SVC virtualization
capabilities.
•
Instant branch provisioning and recovery: Growing organizations that need to rapidly
provision new locations to support dynamic business requirements can quickly establish service
wherever and whenever needed. Servers are quickly and easily booted over-the-WAN in as
little as one minute. In the event of a disaster at the branch office, services can be quickly reprovisioned to continue business operations.
•
Resilient to WAN outages: Though the IT infrastructure has been completely centralized,
remote office workers to have local access to data even when the WAN link to the office goes
down.
•
Centralize data protection: Services and data are protected and secured in the data center,
using the same tools and methodologies applied to all corporate data, eliminating the need to
purchase, install, and manage a backup solution in the branch office. This can reduce recovery
time objectives (RTOs) and gain better recovery point objectives (RPOs).
•
Safeguard data: With storage in the branch, data is exposed to risk. Steelhead EX + Granite
products enable state-of-the-art authentication and encryption to ensure the security of data
assets while in flight from the data center and in-use in the branch.
•
Simplify management: By eliminating the need to maintain and manage stand-alone servers
and storage in branch offices, Steelhead EX + Granite products significantly reduces
administration overhead and costs. A single appliance in the branch is easier to support and by
centralizing storage, data management activities can take place in the data center. Branchbased IT personnel and fly-and-fix missions are no longer required.
•
Better storage efficiency: You can enable storing up to five times more active primary data in
the same physical disk space using IBM Real-time Compression.
•
Continuous application availability: You can enable near-continuous availability of
applications through dynamic migration.

•
Advanced data management capability: The solution provides easy-to-use data
management, designed with a graphical user interface (GUI) and point-and-click system
management capabilities.
•
Better data protection: The solution supports Metro Mirror and Global Mirror for replicating
data synchronously or asynchronously between systems for backup efficiency.

Provisioning storage from IBM Storwize V7000 and IBM System
Storage SAN Volume Controller
This section follows the setup process and shows how to create volumes and make them accessible
from the host. The following steps are required to complete the basic setup of your environment.
1. Create new volumes
2. Map volumes to the newly created iSCSI host
Note: This section assumes that the IBM Storwize V7000 storage system or IBM System SAN
Volume Controller had correctly configured the internal storage disk drives using different Redundant
Array of Independent Disks (RAID) levels and different optimizing strategies.
For more information on how to configure the IBM Storwize V7000 system storage pools, refer the
chapter 7 of IBM Redbooks title Implementing the IBM Storwize V7000 at:
ibm.com/redbooks/redbooks/pdfs/sg247938.pdf
Create new volumes
By default, all volumes that are created in IBM Strowize V7000 storage systems are stripped
across all the available managed disks (MDisks) in one storage pool. The GUI for the IBM
Storwize V7000 system provides mainly the following preset selections.
•
Generic: A stripped volume that is fully provisioned.
•
Thin-provision: A stripped volume that is space efficient. There are choices to help
determine how much space is fully allocated initially and how large the volume is able
to grow.
•
Mirror: The stripped volume consists of two striped copies and is synchronized to
protect against loss of data if the underlying storage pool of one copy is lost.
•
Thin-mirror: Two synchronized copies. Both are thin provisioned.

Summary
IBM Storwize V7000 Unified is a powerful storage system that enables storage virtualization,
consolidation, and automated tiering for businesses of all sizes. The system combines the right mix of
hardware and software components to help IT organizations optimize storage efficiency, improve
application availability, and ensure high utilization of valuable storage resources, all from a single
point of control. In addition, it consolidates block and file data storage into a single system, reducing
complexity and costs.
Riverbed Granite appliances enable the complete consolidation of edge servers and storage to the
data center, while projecting applications and data to edge locations where they perform as if they
were local. The Granite solution enables a global storage infrastructure by intelligently accelerating
storage across the WAN, enabling new efficiency with data management, protection, and recovery
while ensuring performance at the edge. With Granite, organizations can:
•
Reduce costs by eliminating storage from branch offices.
•
Improve management efficiency as maintenance and backup can take place at the data
center.
•
Recover faster and more effectively as the data is stored centrally, protected more frequently,
and can be streamed to the branch office as needed.
•
Improve security of data assets through centralization and state-of-the-art encryption
capabilities.
Tight integration between IBM Storwize V7000 storage system and Riverbed Granite provides simple
configuration and consolidated management while also increasing performance and improving
efficiency at the data center and eliminates additional storage and systems at the branch office. This
in turn, substantially reduces total cost of ownership (TCO) for enterprises.
