Fujitsu Introduces VAAI Support with ETERNUS Disk Storage Systems for VMware vSphere(TM) 4.1
Fujitsu and VMware vSphere 4.1 deliver further significant improvements in performance and scalability for server virtualization environments
The support enables offloading of storage operations, which previously required server resources, onto the higher performance ETERNUS DX400/DX8000, therefore integrating VMware with disk storage functions, reducing server workloads, and making them ideal platforms for large-scale datacenter virtualization and consolidation.
VAAI enhances the performance of VMware vSphere(TM) 4.1 on ETERNUS DX400/DX8000, making it more flexible and operationally efficient, as well as improving the effectiveness of the storage systems.
The high performance ETERNUS DX400/DX8000 now support the following three functions:
1. Full Copy
Data copy operations are performed using the resources and hardware acceleration features of the storage array. This frees the server from read and write operations, and speeds up the overall process. Server workloads are therefore reduced and more effective use is made of all available resources. Data center operators can expect faster virtual machine creation and accelerated movement of data via Storage VMotion.
2. Block Zeroing
This function enables hardware accelerated initialization for the allocation of new storage capacity. The server now only sends one command to the array, which delegates the task of filling the initialized capacity with zeroes to the storage system. This feature further reduces server workloads, speeds up virtual machine provisioning, and results in fewer servers needed to handle application performance.
3. Hardware Assisted Locking
With locking mechanisms being offloaded from the server to the array, locking can be performed at a block level rather than at LUN level. This functionality results in greater granularity that reduces the size of locked sections and improves the performance of common tasks such as virtual machine migration, the powering of many virtual machines on or off, and template-based creation of virtual machines. This feature helps to make virtualized data centers with high VM counts, much more efficient and operationally flexible.
Says Jens-Peter Seick, Senior Vice President Datacenter Systems at Fujitsu Technology Solutions: «According to VMWare's VMmark benchmark, Fujitsu PRIMERGY servers in partnership with Fujitsu ETERNUS storage systems make the ideal virtualization platform across the widest range of customer needs. By supporting all three storage integrations for VAAI with VMware VShpere 4.1, our virtualization-optimized «Dreamteam» stays at the front of the race for reliable and significantly-improved efficiency and performance.»
The ETERNUS VAAI Plug-in (*2) requires the latest V20L60 firmware for ETERNUS DX400/DX8000 series disk storage systems. Fujitsu provides both the firmware and plug-in software free of charge. For the Full Copy functionality the ETERNUS Advanced Copy feature (3*) is required. Fujitsu is a certified member of VMware's vStorage API for Array Integration Partnership Program.
