Realize the Value of Desktop Virtualization With Hitachi Unified Storage and Hitachi NAS Platform -- Solution Profile

  1. 1. Accelerate the Return on Your Virtual Desktop Infrastructure Investment Achieving a successful virtual desktop infrastructure (VDI) deployment depends on several factors. From the user perspective, desktop performance and reliability are critical. From an IT perspective, operational efficiency, ease of management, and price performance top the list. VDI workloads create I/O bottlenecks, placing a heavy burden on storage resources. Meeting stringent VDI requirements calls for storage solutions uniquely designed and optimized for VDI workloads and environments. Realize the Value of Desktop Virtualization With Hitachi Unified Storage and Hitachi NAS Platform SOLUTIONPROFILE Virtual desktop infrastructure allows users to access desktop services from central IT resources without requiring a PC for running locally provisioned applica- tions. The proliferation of VDI solutions has provided solid information on what makes a successful VDI deployment. With storage as a top consideration for VDI success, IT organizations are looking for ways to manage the virtualized desktop environment, improve availability and data protection, and deliver virtualized desktops for business continuity and mobility.1 However, VDI operations require an enormous amount of I/O transactions, which severely tax traditional stor- age architectures. In fact, storage can be the limiting factor in achieving the desired VDI performance, scal- ability and efficiency. Hitachi network attached storage (NAS) systems offer high-performance, reliable and cost-effective access to corporate information from any device, anytime from anywhere.
  2. 2. SOLUTION PROFILE Hitachi NAS Platform systems, with unique hardware accelerated architecture, allow you to quickly deploy a VDI-optimized storage solution that delivers the highest performance, scalability and value. These solutions deliver: ■■ Richer user experience. Extend a high- performance desktop experience and application flexibility to users while enabling IT to respond faster to changing business needs. ■■ Resilient data management. Centralize user data and persona management to improve backup and disaster recovery, making it easier to meet regulatory com- pliance and security requirements. ■■ Agility. Expand and scale through a centrally managed and monitored stor- age ecosystem while easily provisioning resources and creating new virtual desk- top sessions. ■■ Lower capital expenditure (capex). Lower total cost of storage ownership by reducing capex and freeing up IT to address problems more efficiently. Leveraging decades of expertise in creating high-performance storage solutions, Hitachi delivers file server technology specifically designed to meet the needs of a wide spec- trum of VDI environments. Instead of storage becoming an obstacle, Hitachi storage solutions ensure that storage is the engine that accelerates VDI performance, scalability and value. You gain a centralized storage resource that simplifies storage manage- ment and virtual desktop creation, all with a high-definition user experience. At the same time your solution meets critical availability, efficiency and data protection mandates. Hitachi Data Systems Meets the VDI Performance Challenge You need a way to realize the most value from your VDI investment. Hitachi Unified Storage (HUS) and Hitachi NAS Platform (HNAS) gateways create a high-performance architecture that com- bines advanced data management with an integrated storage ecosystem. These Hitachi NAS Platform systems operate in combination with the Hitachi Data Systems comprehensive technology framework. These integrated components deliver an optimized storage solution that effi- ciently addresses stringent VDI storage requirements. The Hitachi NAS Platform architecture offers a well-integrated, high-performance, scalable network storage system that helps solve VDI performance and management concerns. Using a hardware-accelerated “hybrid core” architecture and object-based file system, storage arrays within HUS or HNAS offload VDI tasks such as virus scanning, cloning and boot storms, reducing overhead on the back-end storage system and freeing up critical I/O. Hitachi NAS Platform also pro- vides a native system-based file clone utility, which clones a virtual machine (VM) or VDI instance without adding I/O or increasing storage needs. This utility makes it easy to deploy hundreds or even thousands of virtual desktops in minutes, instead of hours, or even days. At the same time, the utility pro- vides desktop users the performance they demand, with the availability they require. With Hitachi NAS Platform you achieve higher performance and lower total cost of ownership for VMware Horizon View, Citrix XenDesktop and other industry-leading VDI solutions. VDI Workloads Demand Unique Storage Requirements VDI requirements are often more stringent than other applications because users have set expectations for desktop applica- tion performance. VDI is unique because system requirements vary greatly between peak-workload (boot, log-in and virus scan storms) and steady-state workload. Maintaining a high level of performance for all workloads is vital to realizing maximum VDI value. In many instances, the success of VDI implementations is dependent upon users “opting-in” to use VDI instead of a physical desktop. Similar to server virtualization, managing the VDI storage infrastructure presents several challenges. For example, desktop virtual- ization and physical resource sharing by the hypervisor increases demand on the stor- age environment. With multiple independent virtualized desktop images running on a single physical platform, storage must scale with changing business needs. Virtualized desktop images that migrate across physi- cal servers, I/O storms and increased data protection complexity contribute to VDI management challenges. Organizations that neglect the VDI storage infrastructure risk diminished performance, longer response time and higher expenses. Meeting the stringent requirements of VDI calls for an integrated, high-performance solution. An effective solution must be opti- mized from the storage architecture to the storage management center.

Hitachi NAS Platform user persona management preserves user profiles and dynamically synchronizes them with a remote profile repository. It downloads only the files that Microsoft Windows® requires at login, such as user registry files. When the user or appli- cation opens other files from the desktop profile folder, these files are copied from the stored user persona. ■■ Fast access to user personal information with the hybrid-core architecture and CPU off-loading. ■■ Automatic storage tiering of personal information to the most high-performing and cost-effective disks. ■■ Reliable backup and recovery of per- sonal SMB-hosted user data in the event of a disaster or a catastrophic event with Hitachi NAS Virtual Infrastructure Integrator. Intelligent Data Management Using the right disk for the right data is often a manual task. Hitachi NAS Platform systems simplify this effort through intelli- gent, automatic file tiering that extends to I/O-intensive metadata operations. ■■ Mixes high-performance disks with lower cost disks while still achieving the same high performance. ■■ Separates metadata from user data, efficiently and seamlessly to enhance performance ■■ Places metadata on the highest per- forming storage tier, and user data on the slower, less expensive tier, improving system performance at lower cost. Application-Aware Data Protection With thousands of virtual desktops running simultaneously, the risk of losing critical data is a constant concern. Hitachi NAS Platform “object-based” replication creates object- based, space-efficient snapshots of VDI sessions usable as recovery points for fast restoration (see Figure 1). ■■ Improve performance by 2 to 3 times, while boosting incremental replication up to 25 times. ■■ Object replication enables fast failover in the event of a disaster, eliminating duplicate hardware at both ends. ■■ Seamless integration with VMware vCenter provides quick and efficient data management for virtual server and VDI environments.
