Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over private network or internet. Basic foundation of cloud computing is virtualization. With virtualization, multi tenant, and self service concept, then comes up Cloud Computing.
Mandawani has the expertise to help you implement and manage cloud computing infrastructure that can be used to serve your company's internal users and your partners. We partner with Vmware, the industry leader, to deliver Cloud computing solution.
Cisco Unified Computing System (UCS)
The Cisco Unified Computing System (UCS) is an x86 architecture data center server platform composed of computing hardware, virtualization support, switching fabric, and management software introduced in 2009. The idea behind the system is to reduce total cost of ownership and improve scalability by integrating the different components into a cohesive platform that can be managed as a single unit. Just-In-Time deployment of resources and 1:N redundancy can be configured with UCS systems .
Cisco UCS supports several hypervisors including VMware ESX, ESXi, Microsoft Hyper-V, Citrix XenServer and others. VMware Virtualization is provided through a partnership with VMWare and uses a version of that company's ESXi. Unlike the VMware Workstation software, ESX and ESXi run directly on the system hardware without the need for any other software (called Bare Metal), and provide the necessary hypervisor functions to host several guest operating systems (such as Windows or Linux) on the physical server. Guest operating systems are limited to 255 gigabytes of vRAM and 8 virtual processors for vSphere 4.x and has been upgraded to 1TB of vRAM and 32 vCPUs in vSphere 5.0. Additionally the Cisco UCS Virtual Interface Cards incorporate VM-FEX technology that associates Virtual Machines direct access to the hardware for improved performance and network visibility.
VMware ESX is an enterprise-level computer virtualization product offered by VMware, Inc. ESX is a component of VMware's larger offering, VMware Infrastructure, and adds management and reliability services to the core server product. VMware is replacing the original ESX with ESXi.
VMware ESX and VMware ESXi are bare metal embedded hypervisors that are VMware's enterprise software hypervisors for guest virtual servers that run directly on host server hardware without requiring an additional underlying operating system.
The basic server requires some form of persistent storage (typically an array of hard disk drives) that store the hypervisor and support files. A smaller footprint variant, ESXi, does away with the first requirement by permitting placement of the hypervisor on a dedicated compact storage device. Both variants support the services offered by VMware Infrastructure.
Create multiple virtual storage systems within a single physical storage system. NetApp® MultiStore® software enables multiple users to share the same storage resource without compromising privacy and security. Information on one virtual storage system cannot be viewed, used, or downloaded by users on a different virtual storage system.
MultiStore software provides a solid storage foundation for the Secure Multi-Tenancy for Cloud Architecture joint solution from NetApp, Cisco, and VMware.
MultiStore provides secure multi-tenancy capability to the NetApp Data ONTAP® operating system, allowing you to:
MultiStore gives you exceptional flexibility within the framework of a unified, multiprotocol architecture—resulting in a shared storage infrastructure that is more responsive, easier to manage, and less expensive to deploy.
The FalconStor® Network Storage Server (NSS) is a scalable, highly available solution that enables storage virtualization and business continuity in heterogeneous environments. Supporting existing third-party disk arrays, FalconStor NSS eliminates storage boundaries and vendor lock-in, providing fast and easy data provisioning, mirroring, migration, snapshots, and WAN-optimized replication. With integrated support for Fibre Channel (FC), iSCSI, and FCoE protocols, FalconStor NSS provides the benefits of storage virtualization across any IT environment or budget.
