IBM releases storage volume controller version 4.3 for SVC's five-year-old birthday As one of the products of IBM's "Project Big Green", IBM announced the latest version of its storage virtualization software in Beijing on July 22, through a specially designed storage solution to improve equipment utilization, Energy efficiency, availability, and scalability of critical applications help customers manage and integrate large amounts of business data more efficiently. IBM System Storage SAN Volume Controller (SVC) has been launched for five years. The newly released version 4.3 can create integrated virtual resource pools throughout the enterprise, helping IT departments to respond more quickly to customer needs and realize centralized management of resources, thus significantly Improve the flexibility and responsiveness of IT infrastructure. Storage virtualization technology can reduce the need for additional physical storage hardware systems, and ultimately reduce the overall energy consumption of the data center. Virtualization is an important part of IBM's new enterprise-level data center model, designed to help customers improve IT efficiency and promote the rapid deployment of new IT services to support future business development. The new model is based on best practices in virtualization, green IT, service management, and cloud computing. Relying on SVC, the fastest storage virtualization system tested in the industry, IBM has always maintained its leading position in the field of storage virtualization. Since entering the market in 2003, IBM has delivered more than 12,000 SVC engines and more than 4,000 SVC installed systems to customers. Since the data that customers must store is showing exponential growth, it is becoming more and more important for data centers to control storage costs and improve storage utilization. SVC 4.3's functional enhancements can help further increase storage utilization, thereby reducing energy consumption and achieving a greener data center. Mr. Barry Rudolph, Vice President of IBM Storage Series Solutions, said: "IBM is committed to using powerful virtualization technology to help our customers improve their information infrastructure. Since the advent of SVC 5 years ago, we have been in the field of storage virtualization Leading position, the latest version provided today further demonstrates our innovative advantages, and at the same time reflects our commitment to customers-using green and efficient technology in the storage product line to help customers cope with the current data center dilemma . " The newly released IBM SVC 4.3 software includes the following enhancements: *  Space-saving virtual disk-only use disk space when writing data, instead of reserving disk space according to the full capacity of the virtual disk; Although SVC's feature functions are highly dependent on different workloads and are closely related to the customer's data center specifications, the functions provided by SVC (such as the new space-saving FlashCopy) can reduce the data copy space requirements by 75% or More. In addition, a new version of IBM System Storage Produc TIvity Center (SSPC) was also released. As the management console of the SVC system, SSPC integrates the management of virtual and physical infrastructure, and aims to provide customers with an advanced management platform. SSPC is pre-installed with TotalStorage ProducTIvity Center for ReplicaTIon 3.4 version, which greatly simplifies the management of advanced copy services provided by SVC FlashCopy and metropolitan and remote mirroring. IBM TotalStorage ProducTIvity Center software helps customers reduce wasted disk space and improve energy efficiency by providing solutions to identify duplicate data, orphan data, temporary data, and non-business data. In addition, TotalStorage Productivity Center can also identify the frequency of access. There are fewer data files, so these files are migrated to a more energy-efficient storage system, such as tape. Mr. Andy Slater, Chief Operating Officer (COO) of Tectrade, said: "Energy consumption has always been one of our most important concerns for large data center customers. IBM SAN volume controllers are being solved by utilizing the most effective storage utilization technology This concern from customers. Since its launch five years ago, SVC has been improving. SVC 4.3 now provides space-saving FlashCopy function, which only uses disk space when the source and target data are different, instead of copying the virtual disk as a whole The full capacity of the company-for customers who want to reduce their carbon emissions, this is a huge benefit. " The enhanced functions of IBM storage virtualization help promote the green innovation project, which aims to meet customers' increasing demand for greener storage solutions. IBM SVC further strengthens its position as an important green product that can help customers improve the energy efficiency of the data center in many ways, including: * Non-disruptive data migration—Migrate data from the original disk system to the new disk system without interrupting application operation. Customers can quickly start data migration and disconnect from the original energy-efficient storage solution. connection; * Simple implementation of tiered storage-Simplify the tiered storage infrastructure, improve the performance of lower-tier storage, and enable data migration between storage levels at all levels without interrupting applications. In this way, it is easier to match the appropriate storage device according to the data type and migrate the data when the requirements change. In short, these functions can easily mix different types of storage devices to reduce the overall energy consumption; * Improve storage utilization rate-The storage volumes of IBM and non-IBM storage systems can be brought together to form a single storage capacity pool that can be centrally managed to increase the utilization rate of storage devices and reduce the future demand for additional storage devices. This capability can reduce the overall demand for storage hardware, thereby reducing the energy consumption of storage configurations. Mr. Greg Nightingale, Director of Storage Solutions at Sirius Computer Solutions, said: "IBM SAN volume controllers truly bring simplified storage virtualization to our customers because they do not have to rebuild the entire storage infrastructure. SVC does not lock customers in one Vendor ’s solutions. SVC ’s refined technology and simplified management can bring customers a rapid return on investment in several ways-from non-disruptive data migration and seamless data transfer and copy to remote data replication. The new version of SVC includes Enhanced functions such as: Thin Provision can bring more functions, higher flexibility and greater value. In addition, IBM's SVC also meets the market's demand for greener storage solutions: the largest Utilize storage devices to minimize the power and cooling costs required to support IT infrastructure. " In addition to helping customers build more energy-efficient data centers, IBM ’s storage virtualization solutions can also help break the limitations of product adoption for many years. Customers do n’t have to stick to a vendor such as EMC, HP or Hitachi. Storage products. Through IBM SVC, customers can arbitrarily combine storage devices from EMC, IBM, HP, Hitachi, and other vendors to easily virtualize and manage and deploy the devices, gaining unprecedented flexibility and independence. Health club company Lifestyle Family Fitness is benefiting from this feature. Lifestyle Family Fitness opened its first fitness club in Lakeland, Florida in 1982. Headquartered in Tampa Bay, Florida, Lifestyle Family Fitness now owns and operates health clubs throughout the Southeast, Midwest, and Mid-Atlantic regions, and plans to achieve rapid growth in the next five years. According to the International Association of Health, Tennis and Sports Clubs (IHRSA), Lifestyle Family Fitness is one of the 20 fastest growing fitness club companies in the world. The company ’s main data center is located in St. Petersburg, Florida, and includes infrastructure covering storage and servers, and manages key applications of the entire club network, such as employee records, new club members, personal training contracts, and sales and services. data. As it is expected that as the business expands, the company ’s growth and IT complexity will inevitably increase, Lifestyle Family Fitness decided to upgrade its data center infrastructure to address some of the company ’s core applications that it has begun to face. I / O bottleneck problem. The company chose IBM's SAN Volume Controller (SVC) as its storage virtualization solution to solve I / O problems while improving long-term overall energy consumption, saving costs, and maximizing the use of existing hardware. This two-node cluster SVC was implemented in November 2007. It runs on EMC CLARiiON CX300 and IBM System Storage DS4700 disk arrays. It is equipped with two IBM Brocade SAN switches. It has brought higher performance and achieved more High scalability without interruption of operation. Mr. Michael Geis, Director of Information Systems Operations at Lifestyle Family Fitness, said: "The simplified features of the IBM storage virtualization system are extremely attractive to companies like Lifestyle Family Fitness. We hope to minimize our IT infrastructure costs. Because IBM ’s SVC system is compatible with all storage hardware – no matter which vendor comes from, we can save costs by maximizing the use of existing infrastructure, eliminate bottlenecks in accessing member information, and apply many The baseline response time has been shortened from 60 seconds to 10 seconds. Ultimately, SVC has become our best system solution. " The new features of IBM SAN Volume Controller version 4.3 will not bring any additional cost, and existing SVC customers can take advantage of these enhanced functions by upgrading to SVC 4.3.
