Assigned team to provide storage for the enterprise
Storage for any servers/applications
Developers to develop SAN products
Centralized backup and recovery
Stakeholder Use Cases Home Directories User home directories today are stored on local servers with Directly Attached Storage (DAS) and these servers are often underutilized. With Unified Storage, we can fully utilize our total storage capacity and move away from silo storages to a pooled storage model, which also consists of NAS with NFS and CIFS support. We no longer need to worry about the physical limitations of DAS and grow the storage environment dynamically, similar to how Google and Yahoo thin provision to incrementally increase their storage.
Virtualization in the Datacenter
Virtualization is becoming the de facto standard for implementing services in the datacenter—from virtual servers, desktops to applications. Implementing virtualization in the enterprise requires storage for its high-availability needs. The number of guest operating systems or virtual machines hosted inside each physical virtual host depends on the three requirements: storage, CPU and memory. Increasing the number of CPU/cores, storage and memory also increases the number of virtual machines allowed in a single physical host. The more virtual machines a single physical host can handle, the less we need to purchase new servers. We can easily fork-lift the entire datacenter when virtualized to a strategically assigned disaster recovery site. Virtualization and unified storage are the foundation for datacenter resiliency.
One application of virtualization is the establishment of software test environments. In the past, it has been a challenge for DIIT to support software evaluation efforts for the application development teams, due to resource requirements. It takes a lot of time and energy to prepare test environments for this purpose. We are piloting the use of virtualization in a test lab environment in order to provide virtualized resources on demand in support of software evaluation initiatives. This will minimize the amount of time required to build out evaluation computing environments.
The NYCDOE consists of several storage environments where global-interesting data are stored. We can consolidate all these storage environments into the unified storage environment, where it can be managed centrally. This will ease movement of data between databases securely, and increase performance in transactional processing.
Benefits and Impact if Not Implemented
Implementing Unified Storage and using Enterprise Servers for the NYCDOE will realize several organizational goals: from server application to desktop virtualization, and including the idea of campus cloud and on-demand computing, it will transform our datacenter into a more dynamic and resilient environment. Unified Storage with Enterprise Servers is the key to a successful IT consolidation, providing the greatest storage flexibility. Additionally, by exploiting emerging market trends, DIIT will immediately realize long-term reductions in deployment and administrative costs.
If this vision is not implemented, the datacenter will continue to operate as is, without the added efficiency and resiliency of unified storage. We will continue to have servers with underutilized storage and islands of information across the organization. This will also prevent us from moving towards the development of a sustainable and dynamic datacenter. Without the right foundation, we will operate inefficiently, and we are unlikely to lower total cost of ownership due to ever- growing demand for storage and servers.
