To keep up, it seems as if the IT department is always being asked to add storage capacity to servers or the storage area network (SAN). At the same time, you hesitate to spend more money on storage hardware because you know that typically half of any company’s storage space is unused, idle, costing money. In fact, the actual cost of the underused storage hardware is two to five times more than the initial procurement cost. In today’s economy, that’s not acceptable.
To satisfy the access and availability demands in today’s distributed, need-it-now business environments, enterprise data storage is becoming network-centric. But hardware alone is not enough to create an effective, cost-efficient network storage strategy.
The servers and network components must be managed to optimise the data flow and provide backup and failover services so mission-critical data is always available. You must have quality software to reap the benefits of network storage — without it, the result is a more complex, expensive, and hard-to-maintain storage environment.
The need to handle increasing amounts of data raises key IT strategy questions. As you introduce new applications, will you be able to seamlessly integrate your new or acquired resources into your existing storage infrastructure? Will you be able to fully exploit all your storage resources? Do you have the appropriate storage network in place that adapts and scales to meet the demands of your fluid business model? How do you know if you have sufficient storage to ensure that data is accessible, highly available, protected from failure, and optimised for your infrastructure?
Are these questions difficult to answer? Not with VERITAS. Unlike the storage hardware companies that sell you storage every time you need to add a new server or expand your SAN segment, VERITAS lets you use your existing storage resources more efficiently and effectively. Its multi-platform support means you can use Unix- and Intel-based server storage across applications.
More important, the VERITAS suite of network storage solutions lets you understand and configure your enterprise storage to best fit your environment. VERITAS is so flexible, it lets you use NAS, SAN, and even Direct-Attached Storage (DAS) in any combination, so you can optimise both your network configuration and your storage utilisation and management functions.
That’s because VERITAS understands that each enterprise is unique, and that there are many appropriate approaches to managing data and making it available to users. And because VERITAS isn’t selling storage hardware, its solutions don’t force you to buy expensive boxes to get the application performance and management tools you need.
Support for All IT Storage Strategies
Terms like “SAN” and “NAS” become loaded with artificial and sometimes arbitrary meaning, which can inhibit the effective use of the technologies.
In reality, both are legitimate IT approaches to storing data in a way that makes it available across networks, both to users and to computers and other hardware systems. Enterprise-level network storage architectures encompass SAN, NAS, and the integration of DAS into these architectures, so IT can create appropriate storage and system network topologies that deliver guaranteed levels of data availability, security, and manageability.
Whether your storage infrastructure contains DAS, NAS, a SAN, or a combination of these architectures, VERITAS solutions provide consistent storage management.
This means that administrators do not need to learn new storage or operating-system-specific tools as the environment changes. This leads to greater IT productivity and lowered training costs.
VERITAS ServPoint solutions manage all these architectures, in a homogeneous or heterogeneous environment, so IT professionals have increased flexibility and control, leading to a lower cost of operation and ownership.
The VERITAS ServPoint NAS appliance provides the file-serving software that works on any standard Sun or Intel system, converting it into an intelligent NAS appliance, and provides virtualisation and data management tools to serve files in a homogeneous and heterogeneous (Unix/Windows) environment.
(Virtualisation presents multiple physical storage devices from various vendors as higher-level, logical devices that can be managed more easily and efficiently.) ServPoint NAS and ServPoint SAN enables users to take file sharing and storage virtualisation services to a new level, enabling them to centralise and consolidate file serving and virtualisation of enterprise wide storage.
This enables users’ customers to better utilise their existing server and storage resources with increased flexibility in the pooling, provisioning, sharing, and management of servers and storage devices. VERITAS takes a standard server and convert it into an intelligent file- or block-serving engine that uses existing, SAN, NAS, or DAS storage, so there’s no need to buy special hardware.
VERITAS SANPoint lets an IT department manage all its storage resources — both network and local — such as monitoring where data is located and its utilisation characteristics, monitoring and controlling application usage, and setting policies for failover strategies, access priorities, and availability requirements.
The Power of Network Storage Put to Work
VERITAS’ expertise in virtualisation is undisputed, as its 79.9 percent market share (according to Gartner) of virtualisation tools attests. At the heart of the company’s virtualised network storage solutions are its industry-proven volume management and file system technologies, which deliver both cluster and non-cluster functionalities.
The VERITAS Cluster File System (CFS), and the VERITAS Cluster Volume Manager (CVM) have also been integrated into VERITAS Database Edition AC, which lets IT build highly scalable clusters of databases that, when connected to the network via VERITAS NAS and/or SAN tools, brings the high availability, managed accessibility, and failover protection to VERITAS’ network-storage solutions. To protect network storage data, VERITAS delivers a number of highly scalable data protection solutions through VERITAS NetBackup, which integrates seamlessly with its network storage management solutions.
This approach to network storage is being well received. “The combination of VERITAS Volume Manager and VERITAS Cluster Server enables us to give our clients very high SLAs,” says James Dean, Director of Enterprise Backup at USinternetworking, Inc. “The combination of these two software pieces allows us to run everything in our enterprise redundantly.” USi uses VERITAS Volume Manager to mirror the operating system drives — which reduces downtime due to failure — and VERITAS Cluster Server to provide server-level redundancy. “And as a saving grace,” Dean says, “we have VERITAS NetBackup DataCenter, which allows us to maintain and protect every bit of data that we have.”
For enterprises that already have SANs in place, VERITAS Network Storage Solutions let an IT department virtualise data, making it available across the entire network, not just within the SAN. These solutions also provide administrators the ability to share and manage storage easily with VERITAS SANPoint Control within existing IT setups.
VERITAS network storage solutions enable users to support and manage the growth of data in the enterprise. Through the use of VERITAS Network Storage Solutions, which are designed to operate in heterogeneous server and storage environments and with different storage and network architectures and topologies, IT departments can now ensure data availability, security, and manageability to meet service levels committed to various lines of business within a company as well as to the company’s clientele.
