Virtual Storage Virtual Servers

  1. 1. Virtual Storage + Virtual Servers Using Virtualization Consolidating hardware resources into virtual storage, servers, operating systems, applications or networks allows any organizations to improve efficiency and simplify the management of its IT infrastructure. Since its founding in 2000, StoneFly has been applying the principles of virtualization in the development of simple-to-operate, highly available, high-performance IP SAN technology. With StoneFly’s StoneFusion Operating System, centralizing storage resources into an intelligent storage area network, with advanced storage services allows organizations to increase storage utilization and remove islands of underutilized disk resources. StoneFly’s virtualization engine applies networking principles for efficient storage management. Each Stonefly Storage Concentrator creates centrally managed pools of storage from multiple physical resources. These pools are managed by the Storage Concentrator and are carved out into iSCSI logical volumes; separating the iSCSI intelligence from disk and RAID hardware. With this layered approach, StoneFusion’s advanced storage management is able to improve SAN reliability, availability, and scalability (RAS) for data recovery, data protection, and creating virtual-disk templates in order to simplify system provisioning. Server Virtualization enables organizations to consolidate physical servers into a single system running multiple operating systems and applications to increase system utilization. Virtual servers benefit from a centralized and virtualized storage infrastructure environment to reduce system management requirements, capital expenditures, and administrative overhead. By using StoneFly IP SANs, and advanced storage virtualization and provisioning, with virtual servers, IT administrators can: • Deploy storage networks with existing Ethernet infrastructure for seamless storage integration • Simplify storage deployment for virtual machines without suffering system downtime • Eliminate application downtime with easy storage resource expansion • Expand storage on the fly with efficient storage provisioning and centralized iSCSI storage pools • Expedite virtual server deployments by using StoneFly Reflection to create pre-configured virtual server “templates” • Centralize storage and server volume management • Utilize clustering technology for building highly available server and storage infrastructures Benefits of StoneFly IP SANs StoneFusion-powered storage can be easily deployed in environments requiring tiered storage, high availability, or flexibility. • Stonefly Modular Storage Concentrators (MSC): MSCs are designed for mission critical deployments requiring flexibility, tiered storage, clustering and high availability.
  2. 2. • Stonefly Integrated Storage Concentrators (ISC): The cost-effective ISC product line is an easy to deploy IP-SAN-in-a-Box, providing integrated storage and management. • Stonefly Hybrid Storage Concentrators (HSC). The HSC product line is the best of both worlds, offering the benefits of Stonefly clustering and the ease of IP SAN-in-a-Box deployment. Deploying a StoneFly IP SANs with VMware Virtual Infrastructures Figure 1 StoneFly IP SAN + VMware Virtual Infrastructure The VMware Infrastructure Storage Architecture manages and presents the storage to virtual machines independent of the physical storage environment that is attached to it. Applications and virtual machines are unaware of the characteristics of the storage device beyond its virtual HBA (host bus adapter). For each VMware virtual machine, StoneFly iSCSI volumes are seen as locally attached SCSI disks. Cloning and adding a mirror image to a volume is remarkably VMware Storage / SAN Compatibility fast and efficient. Using StoneFly’s Reflection technology to manage disk Hardware Compatibility List Link: images and virtual server templates, allows administrators to deploy new (See StoneFly on page 41) virtual machines in minutes, simplifying application server deployment and management. A virtual machine can be provisioned additional storage by hot-adding virtual hard disks (or expand existing virtual disks) from the StoneFly SAN without causing any system downtime. Additionally, key VMware technologies including VMotion, HA (High Availability), and DRS (Distributed Resource Scheduling) are also supported and offer organizations a simpler solution for building DR and remote sites for business continuity applications.

Xenserver’s core hypervisor application has revolutionized virtual server deployments with its open source background. Xenserver has been designed from the ground up to be platform and operating system agnostic, and supports VMware and Microsoft virtual servers and disk images in addition to the Xenserver format. With robust paravirtualization and an enthusiastic developer community Xenserver is integrated into many industry leading operating systems and server hardware systems from Red Hat to Dell Computer. Xen leverages virtualization ready processors and Xenserver Storage Compatibility operating systems for a high- performance virtual servers that Hardware Compatibility List Link : utilize standard server hardware, not emulated hardware drivers fro environments where bare-metal performance is critical. Additionally, StoneFly IP SANs support key Xen technologies including XenMotion live migration, XenCenter comprehensive management, and VM layer resource quality of service, offer organizations a flexible platform for building disaster recovery and remote sites for business continuity applications – and simplifying system deployment and administration. Deploying IP SANs with virtual server technologies is an ideal way to consolidate server and storage administration, gain organizational efficiencies, simplify the deployment of new applications, enhance disaster recovery, and improve business continuity initiatives. Implementing a StoneFly IP SAN with VMware’s Virtual Infrastructure offers IT administrators an easy way to manage and reduce complexities in their IP infrastructure.
