666  IBM System Storage DS3500: Introduction and Implementation Guide
22.1  Introduction to IBM VMware Storage Solutions
Many companies consider and employ VMware virtualization solutions to reduce IT costs 
while increasing the efficiency, utilization, and flexibility of their hardware. In fact, 190,000 
customers have deployed VMware, including 96% of Fortune 1000 businesses. Yet 
maximizing the operational benefits from virtualization requires network storage that helps 
optimize the VMware infrastructure. 
The IBM Storage solutions for VMware offer customers:
ň° Flexibility: Support for iSCSI and Fibre Channel shared storage, plus HBA and storage 
port multi-pathing and boot from SAN.
ň° Performance: Outstanding high-performance block-level storage that scales with 
VMwareâs VMFS file system, independently verified high performance by the SPC-1, 
SPC-2 and SPCvirt_sc2010 (Storage Performance Council) benchmarks, and balanced 
performance delivered by the IBM DS3500 Storage System for mixed applications running 
in a virtual infrastructure.
ň° Horizontal scalability: From entry-level through midrange to enterprise class network 
storage with commonality of platform and storage management.
ň° Hot Backup and Quick recovery: Non-disruptive backup solutions using TivoliÂŽ and 
NetBackup with and without VCB (VMware Consolidated Backup). Quick recovery at the 
file or virtual machine level.
ň° Disaster recovery: DS3500 Enhanced Remote Mirror offers affordable disaster recovery 
with automatic failover in conjunction with VMware vCenter Site Recovery Manager 
(SRM).
ň° Affordability: Low TCO shared storage with included IBM Storage System DS Storage 
Manager Software (Storage Manager) and no separate software maintenance fees, 
cost-effective tiered storage within the same storage system, leveraging SAS drives for 
high performance and, SAS Nearline drives for economical capacity.
ň° Efficiency: Data Services features, such as FlashCopy and VolumeCopy enable VMware 
Centralized Backup to disk and eliminate backup windows, and provide required network 
storage for VMware ESX Server features, such as VMware vMotion, VMware Storage 
vMotion, Resource Pools, VMware Distributed Resource Scheduler (DRS), and VMware 
High Availability. Storage I/O Control gives you the chance to adjust your Storage I/O to 
match the mixed Workload in your environment.
VMware vSphere includes components and operations that are essential for managing virtual 
machines. The following components form part of the new VMware vSphere suite:
ň° VMware ESX/ESXi server
ň° VMware vCenter Server
ň° Storage I/O Control (SIOC)
ň° Datastore
ň° Host Agent
