Resumen del manual
Realizing these benefits requires a shared storage foundation that contributes to an optimized VMware infrastructure. The challenge for IT is to achieve the full potential of VMware benefits, which in turn demands the right storage solution. DS4000 and DS5000 Storage Solutions VMware enables the consolidation of application processing to maximize server utilization and reduce operational costs. Using virtualization, multiple Virtual Machines run simultaneously and independently on one or more shared processors. Virtual Machines can be shifted between physical servers in a VMware resource pool with no downtime, allowing them to be dynamically and automatically allocated to the most appropriate host in order to achieve target service levels. This virtualization requires a shared storage infrastructure that enables VMware functionality such as High Availability clusters, VMotion, Resource Pools, Dynamic Resource Scheduler and Site Recovery Manager. The VMware storage foundation supports and complements the VMware Infrastructure by allowing boot from SAN, providing multiple paths for failover, consolidating storage, increasing storage utilization, and reducing the total cost of storage ownership. The IBM DS4000 and DS5000 series offers additional capabilities that go beyond what other disk storage systems can provide in a VMware Infrastructure. These important capabilities, summarized below, qualify the IBM System Storage DS4000 and DS5000 as the right storage solution to achieve more VMware benefits. “In conjunction with VMware, IBM has certified all models of the DS4000 and DS5000 series with ESX Server 35 and ESX Server 3i. The certification tests demonstrated interoperability, boot from SAN, and multipathing for failover of HBAs and storage ports as well as interoperability with SRM 1.0 ( Site Recovery Manager).” • Extensive upgradability, impressive scalability. The DS4000/DS5000 series is a modular family of disk storage systems that has a common management interface, uses a common drive enclosure, and provides identical functionality across models. Utilizing industry-unique DACstore technology, data written by one controller is recognized by all other controllers in the family, which enables data-intact reconfigurations, migrations and upgrades. This means the smallest DS4200 can be upgraded with data intact to a 224-drive DS5000 that features up to 168 TB of physical storage capacity, 32 or 16 GB of controller cache, sixteen host (SAN) ports and sixteen drive ports. The extensive upgradability of the DS4000 and DS5000 series allows you to “pay as you grow” in a VMware Infrastructure. The powerful DS5000 was designed for balanced performance capable of handling numerous applications that demand mixed transaction and sequential workloads. As Virtual Machines proliferate, you can add drives to scale I/O performance, throughput and capacity since the DS5000 never becomes controller bound. This impressive scalability feature further enhances your ability to “pay as you grow” in a VMware Infrastructure while maintaining service levels. • Virtual partitioning, cost-effective tiering. DS4000 and DS5000 storage partitioning allows the DS5000 to logically function as 512 virtual storage systems with up to 131,000 logical drives. Virtual storage systems leverage the virtualization capabilities of VMware by simplifying the mapping of Virtual Machines to storage. DS4700, DS4800 and DS5000 disk storage systems support an intermix of high performance Fibre Channel drives and high capacity SATA drives, enabling tiered storage in a single system. Combined with storage partitioning, tiered storage allows storage classes to be created that better match storage characteristics to application requirements. One such example is to use one partition for production data while a second partition is used for backup or data protection purposes. Such storage classes can lower storage costs while meeting application performance requirements. Together, tiered storage and partitioning promote storage consolidation, lower storage costs, and can raise Virtual Machine service levels in a VMware Infrastructure. • Enhanced availability. Besides typical availability features such as RAID (including RAID 6), redundant/hot-swappable parts, online firmware upgrades, controller failover, the DS4000 Series offers additional capabilities that help enhance the availability of storage in a VMware Infrastructure. • Dynamic Capacity Expansion allows disk drive expansion units to be added for capacity and performance scaling without impacting Virtual Machines and the applications they host. • Dynamic RAID Level Migration permits the RAID level of an array group to be changed for performance tuning without interrupting user access to data. • Dynamic Segment Size Migration allows the data stripe size of an array group to be changed nondisruptively in order to further tune performance. The advanced availability features of the DS4000 Series can help rais...
