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, IBM Storwize V7000 and Storwize V7000 Unified are virtualized storage systems to complement 2 virtualized server environments that provide unmatched performance, availability, advanced functions and highly scalable capacity never seen before in midrange disk systems. As members of the IBM Storwize family, Storwize V7000 and Storwize V7000 Unified are powerful midrange disk systems that have been designed to be easy to use and enable rapid deployment without additional resources. Storwize V7000 supports block workloads, whereas Storwize V7000 Unified consolidates block and file workloads into a single storage system for simplicity of management and reduced cost. Storwize V7000 and Storwize V7000 Unified are virtual storage systems that offer greater efficiency and flexibility through built-in SSD optimization and thin-provisioning technologies. Integrated IBM Real-time Compression enhances efficiency even further by enabling storing up to five times as much active primary data in the same physical disk space. Storwize V7000 and Storwize V7000 Unified advanced functions also enable nondisruptive migration of data from existing storage, simplifying implementation and minimizing disruption to users. Finally, these systems also enable you to virtualize and reuse existing disk systems, supporting a greater potential ROI. Figure 1: IBM Storwize V7000 Unified configuration Features Automatic migration of frequently accessed data to high performing SSDs Provisioning support for business applications that need to grow dynamically, but only consume the storage space they are actually using Migration capabilities that provide efficiency and business value in a nondisruptive migration IBM Real-time Compression for extraordinary efficiency, enabling storage of up to five times as much active data in the same physical disk space Unified storage capability for greater simplicity and efficiency 3 Policy-based file management Support for near instant data copies for backup or application testing Integrated instant copy capabilities for critical business needs Integrated tools and capabilities for server and storage management Clustered systems to support growing business needs while controlling costs Hardware summary 2U rack-mountable chassis Twenty-four 2.5-inch drive bays (model x24) or twelve 3.5-inch drive bays (model x12) Up to 36 TB of physical storage per enclosure using 3 TB nearline SAS disk drives, or up to 24 TB physical storage per enclosure using 1 TB nearline SAS disk drives SAS disk drives, nearline SAS disk drives, and SSDs Redundant dual-active intelligent controllers 16 GB cache memory per control enclosure (8 GB per internal controller) as a base feature For each control enclosure: Eight 8 Gbps Fibre Channel ports (four 8 Gbps Fibre Channel ports per controller), four 1 Gbps iscsi and optionally four 10 Gbps iscsi/fibre Channel over Ethernet (FCoE) host ports (two 1 Gbps iscsi and optionally two 10 Gbps iscsi/fcoe ports per controller) File module provides attachment to 1 Gbps and 10 Gbps network-attached storage (NAS) environments Control enclosure supports attachment of up to nine expansion enclosures with configurations up to 360 TB physical storage capacities (up to 1.44 PB in clustered systems) Dual power supplies and cooling components IBM System Storage SAN Volume Controller Figure 2: IBM System Storage SAN Volume Controller 4 The IBM System Storage SAN Volume Controller enables a single point of control for disparate, heterogeneous storage resources to help support improved business application availability and greater resource utilization. The objective is to identify all storage resources in the IT infrastructure and to make sure that they are used to the advantage of the business and do it quickly, efficiently, in real time, while avoiding administrative cost. IBM System Storage SAN Volume Controller supports attachment to servers using iscsi protocols over IP networks at 1 Gbps or 10 Gbps speeds, which can help reduce costs and simplify server configuration. IBM Storage System SVC also supports FCoE protocol, enabling use of converged data center infrastructures. This new capability simplifies data center and ease management by using the same network for storage, WAN, and LAN. Highlights Manage heterogeneous storage from a single point of control Move data among virtualized storage systems without disruptions Store up to five times as much active data in the same physical disk space using IBM Real-time Compression Simplify storage infrastructure with support for FCoE protocol Allow for nondisruptive scalability from the smallest configuration to the largest Implement stretched configurations for high availability and data mobility between data centers 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 5 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. Figure 4: Riverbed Steelhead EX + Granite topology with remote file servers 6 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. 7 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.
