Taiju Life Insurance Company Limited, which underwent a merger with Nippon Life Insurance Company in 2016 and then changed its name from Mitsui Life Insurance Company to its current name in 2019, is aiming for further growth. As life insurance products become more sophisticated, the company is working on “growth in sales” through the sales staff channel and “growth in the direct writing field” through the supply of products to over the counter sales at banks, agents and Nippon Life Insurance. In addition, the company is accelerating its growth by “strengthening and improving the efficiency of the direct writing capabilities” and “strengthening the wholesale field”. To support these strategies, customer-oriented business operations, strict compliance, human resource development and the creation of an energetic workplace are all key factors for Taiju Life Insurance. In terms of its system, in order to demonstrate synergy as part of the Nippon Life Insurance Group, the company is constructing an easy to use and secure platform that will strongly support improvements to sales strategy and flexibly adapt to environment changes. Moving forward, while aiming to prepare for digital transformation, the company’s plan is to actively construct a new platform that will allow it to pursue a multi-cloud solution, among other goals. Taiju Life Insurance is also working on security measures in accordance with the “Policy on Initiatives to Strengthen Cyber Security in the Financial Sector” published by the Financial Services Agency in 2015. After considering all the circumstances, including the effect on operations, the company decided to adopt a network separation strategy in which a virtual environment is constructed on the server side, and the Internet environment is separated logically. Initially, this project needed to be constructed in a short time period in order to be completed before the international sporting event that had been scheduled for summer of 2020. The company ha

Korea Western Power Co. (KOWEPO) faced the challenge of maintaining business continuity amid the global pandemic. As a leading power supplier contributing approximately 10% of the nation’s total power generation capacity, it was crucial for KOWEPO to adapt quickly to allow remote working. This adaptation was necessary to ensure staff safety and maintain core headquarters functions to provide uninterrupted power to the region. The pandemic created a volatile, uncertain, complex, and ambiguous (VUCA) environment, necessitating a robust solution to enhance business resiliency. KOWEPO needed a solution that could be deployed rapidly to enable their workforce to work remotely without compromising on security or access to essential applications.

Keio University faced challenges in managing and operating virtual environments across its campuses and university hospital. The Information Technology Center (ITC) managed the educational divisions, while the Hospital Information System Division managed the hospital. Each campus ITC struggled with the operation and management of virtual environments for education and research systems. The ITC Headquarters considered replacing the virtualization platform run by a 3-tier configuration system deployed on multiple campuses. The goal was to simplify operation and management of the virtualization infrastructure.

The servers and storage infrastructure at William Jessup University were strained due to years of limited IT budgets. The college had 34 servers, 20 of which were virtualized with VMware, and the rest were standalone physical servers. The hardware was aging, with some already out of warranty. Memory capacity on the VMware hosts was over-provisioned by 2x, resulting in near-constant ballooning issues. The processors in the hosts were mixed Intel and AMD, which could not support failover using VMware HA. The primary storage system was a 10-year-old HP SAN with a single controller and only 2.5 TB of capacity. The dramatic growth in student enrollment in recent years meant more resources were needed for IT to meet the surge in demand for more performance, capacity, and a disaster recovery initiative. The IT department wanted to upgrade storage and had narrowed down their choice between Nimble and Tegile hybrid flash storage systems. However, they learned about the Nutanix converged compute and storage architecture, which intrigued them and caused them to reconsider their options.

When Chris Mowery joined Cleveland State Community College as Director of Information Technology, he and his team inherited a VDI pilot project that was not working out. It was a 25-client system running on a rack server and iSCSI SAN. The performance was poor, even slower than physical desktops. The platform was also difficult to manage, even for a small configuration, and scaling it out was not going to be financially possible. However, the benefits of VDI, especially simplified desktop administration, still appealed to them. They decided to look at other options and discovered the Nutanix Virtual Computing Platform hosting VMware ESXi and Horizon View was exactly what they needed. The college’s mathematics lab exemplified the desktop challenges they faced. The lab is high-use and stays full most of the day. The hardware was a mix of 90 old and new computers. Management was time-consuming, and the lab itself was too hot due to high thermal output.

The original VDI system at Vitacost.com was running on legacy Dell servers and EMC SAN storage, which were shared with other datacenter applications. This setup led to slow and unresponsive virtual desktops, with applications taking a long time to load, resulting in frequent user complaints about performance and speed. Administrators faced challenges as the task of recomposing images took all night, and system resources were maxed out, preventing the addition of more desktops. The IT staff considered alternatives like rack servers with Fusion-io PCIe flash storage cards and SAN storage on the backend, but the costs were high. They desired a dedicated infrastructure for VDI to avoid interference with other datacenter applications.

Joseph Chamberlain College (JCC) faced challenges with its aging and complex SAN and blade infrastructure, which was impacting performance for end users and demanding more effort from the IT staff. The college needed a high-performance, agile server and storage infrastructure to run all mission-critical workloads, including MS SQL and Exchange. The goal was to find a simple, easy-to-manage infrastructure that could support the school's innovative, technology-focused campus and core curriculum, while maintaining its reputation as a state-of-the-art, innovative sixth form college.

Claranet France faced a challenge when their SAN storage system reached end-of-life. The existing system was used for web and application hosting in a VMware virtualized environment, but it lacked the flexibility and scalability needed to efficiently serve a large number of clients. The traditional SAN proposed by the major storage vendor did not meet Claranet's requirements for fast and flexible provisioning. Claranet needed a solution that could easily scale and provide high IOPS performance to support multiple VMs simultaneously. The team learned about Nutanix at VMworld in Barcelona and began exploring its potential as a solution to their challenges.

Bentleys Queensland faced the challenge of modernizing its IT infrastructure to improve performance and efficiency. The existing fleet of aging desktops and laptops running Windows XP was inadequate for the latest 64-bit applications, leading to slow performance and inefficiencies. The IT administrators found it time-consuming to update and replace physical desktops, which required creating new images with applications for each device. The firm needed a cost-effective, high-performance, and power-efficient solution to transition from server virtualization to desktop virtualization. Additionally, Bentleys needed to ensure that the new solution would fit within their budget and provide a lower total cost of ownership.

When Charlie Kavaloski joined Bauer Built Tire as the Director of IT, his first mission was to modernize the company’s server and storage infrastructure. It consisted of 22 Dell blade and rack servers with direct-attached storage supporting all enterprise applications. The infrastructure was old, out of warranty and no longer supported. Performance was inadequate for the company’s 160 users, and occasionally an application froze and the associated server had to be rebooted. The equipment stretched and sprawled across three racks in the datacenter. He felt the new infrastructure needed to be completely redesigned – virtualized, less complex and more consolidated.

FPI needed a standalone server and storage platform to host VMware Horizon View for a banking client. The platform had to be separate from existing servers and storage to avoid interference with other production applications. VDI is known for demanding high IOPS performance, and FPI required a solution that could meet these demands efficiently. A reseller introduced the Nutanix Virtual Computing Platform as a converged, SAN-free solution for VDI. FPI evaluated this solution against others, including EMC storage and Cisco UCS blade servers, but found Nutanix to be more cost-effective.

The IT department at Farmers Insurance Group Federal Credit Union (FIGFCU) was transitioning from Citrix XenApp to a virtual desktop infrastructure (VDI) and needed server and storage infrastructure to support it. VDI hosts user desktops on a centralized server and streams the display data to client devices. VDI is easier for IT to manage and support than traditional desktop computing environments, and the total cost of ownership is lower. At the same time, it is especially important the servers and storage have ample performance and high availability because all users depend on them for their desktop and day-to-day work. Rodney Perkins, IT Director at FIGFCU and VDI project leader, learned about the Nutanix Complete Cluster as a platform for VDI and was intrigued about what he had read and researched in trying to find the right fit for his environment. The Complete Cluster’s scale-out architecture and converged compute and storage provide a small footprint and avoid the expense of a SAN. Its built-in hypervisor and performance and availability features are well-suited for VDI.

Anthelio Healthcare faced a significant challenge in estimating server consumption and storage needs for a large-scale VDI deployment across multiple hospitals. The existing SAN-based architecture was insufficient to handle the high IOPS performance numbers required by the customer. The project scope had grown too large, necessitating a more efficient and scalable solution to meet the client's demands.

Mason IT needed to build a scalable and sustainable cloud platform for hosting infrastructure-as-a-service. The company was looking for a solution that could reduce power, cooling, and space requirements while avoiding the costs associated with traditional SAN equipment. Additionally, they required a system that could scale easily as client demands grew, without large upfront capital expenditures.

As the DeWitt IT organization began looking at options to support remote employees, cost and performance were big concerns for them. Initially, VDI was not even a consideration due to the infrastructure cost implication. The team was considering investing in an 8-10U Fibre Channel SAN with two hosts and 15TB data storage. The team gauged that this infrastructure would not have been feasible to support VDI because of performance issues from the shared Fibre Channel switches, limited redundancy and long ROI for the capital investment. Reproducing its existing production infrastructure to support VDI was too cost-prohibitive, estimated at $150,000 with only minimal redundancy.

To stay at the forefront in their industry, NJVC, a leading technology services provider for government and commercial customers, needed to demonstrate their capability to rapidly deploy VDI implementations. They decided to migrate their corporate desktops to a VDI solution and aimed to go live with the first phase within forty-five days. Nicholas Perjak, the NJVC Senior Systems Engineer, initially found the target date unrealistic. However, he accepted the challenge and began researching options. The team ranked industry players based on criteria like system performance, scalability, complexity, cost, high-availability, storage features, and network stack features. Most vendors excelled in one criterion by compromising another, but Nutanix offered all desired features and performance standards at a lower cost and with less complexity.

With PH Tech’s rapid growth over the past few years, the systems that have supported the company and that have helped make it a success have been placed under increasing amounts of stress. For the IT department, co-managed by System Administrators Kevin Waddell and Greg Straw, this stress was most apparent in the performance of the data center. As more and more clients were added to the system, keeping the data center performing in top condition had become an increasingly time- and labor-intensive task. As Kevin describes it, “We were facing more and more IOPS challenges every day, trying to maintain the throughput from our SAN. Most of the work we did each day was related to maintaining high performance levels across the system.” A key issue the team identified was the need to incorporate smart storage capabilities like heat mapping into the system so that they could maximize performance and storage while keeping costs to a minimum. With an increasing customer base and limited resources to handle the growing workload, though, any smart storage solution would have to be automated, scalable, and cost-effective.

With continued international expansion, the Orrick IT department was looking for new ways to cost-effectively support additional virtualization efforts while meeting the performance requirements of its end users, including office staff and developers. In addition, the IT management team wanted to improve organizational efficiency by enabling a more diverse group of IT personnel to deploy and manage virtualized workloads without requiring a specialized team with virtualization, server and storage management skills. Over the past two years that the Orrick IT team began developing its virtualization efforts, it accrued multiple vendors for server and SAN hardware, as well as two different kinds of fibre switches, resulting in six interfaces and vendors to work with. As the team deployed additional virtualized workloads from testing and development to production, they would bring on more capacity to support these new workloads but quickly ran into performance challenges such as disk contention issues. For their remote access use case, the IT team had virtualized 6 Citrix XenApp servers for each of its three regions. A snowstorm caused the amount of remote access traffic to spike due to additional users. The IT team quickly realized the IO requirements would demand significant overprovisioning of storage to meet the desired performance characteristics and ensure a good user experience whenever traffic significantly increased.

Software testing and development at InComm was falling behind due to the lengthy time required to provision new test environments. The IT operations group was overwhelmed with demands for new production systems, which took precedence, causing delays in fulfilling requests for testing and development. InComm's prepaid card business relies on a continuous stream of new software applications developed and tested in-house. However, the development process was hindered by the inability to provision testing and development environments promptly. To address this bottleneck, InComm needed a server and storage system capable of provisioning a large number of VMs for test and development, with fast rollout being critical to the business.

Riverside Company faced the challenge of consolidating its aging server and storage infrastructure from five different sites across the U.S. into a single data center located in New York. The existing infrastructure supported critical applications such as Microsoft Exchange, SQL Server databases, file and print servers, and web servers. However, the distributed and siloed environment was difficult to manage and lacked high availability features. The IT department had been reorganized and centralized, prompting the IT director to seek a centralized infrastructure solution. Initially, they considered deploying a VMware virtual environment supported by a traditional enterprise SAN from vendors like EMC or NetApp. However, the cost associated with a SAN, including its footprint, ongoing maintenance, and power consumption, presented a significant budgetary challenge.

Leitner, Williams, Dooley & Napolitan, a legal defense firm, faced a significant challenge when they planned to upgrade their software to Microsoft Windows 7 and Office 2010. This upgrade necessitated more robust PC hardware, presenting the firm with a choice: either maintain their traditional desktop environment and roll out new PCs or adopt a Virtual Desktop Infrastructure (VDI) to run virtual desktops on a centralized server. The firm recognized that VDI could simplify administration by standardizing desktops and allowing updates to be pushed to all clients from a single location, rather than managing customized physical desktops across their geographically distributed offices. After testing a VMware View pilot for nearly a year, they concluded that it could deliver a satisfactory user desktop experience. However, they needed a server and storage infrastructure that offered fast performance and high availability. As a customer of HP and EMC, they initially considered traditional clustered servers and SAN storage. However, their reseller, United Data Technologies (UDT), proposed the Nutanix SAN-Free, converged compute and storage platform as an alternative. William Tomlinson, IT Director at Leitner, was immediately impressed by the potential of the Nutanix solution.

The South Taranaki District Council was experiencing significant performance issues with its VMware View VDI implementation. User log-on times and application response times were unacceptably slow, and the performance decreased exponentially with as few as ten virtual desktops online. This slowdown also affected other applications in the IT environment, such as local government software, financial systems, SharePoint, and geographical information systems. The existing IT infrastructure, which included a substantial investment in a new HP enterprise array/SAN, was overwhelmed by the VDI implementation. Despite efforts to optimize the system with the help of Unidesk, a software and services company specializing in VDI implementations, storage I/O remained a critical bottleneck. The Council faced the prospect of investing an additional NZ$190,000 in performance upgrades for the HP SAN, but questioned the wisdom of reinforcing an infrastructure that was not optimal for VDI.

The Ohio Army National Guard faced the challenge of outdated server and storage hardware that had reached the end of its 5-year warranty. The existing infrastructure, consisting of first-generation HP blade servers and iSCSI and Fibre Channel SANs, was no longer adequate for the current application workloads. The Guard needed a new infrastructure that could support existing applications and a new Virtual Desktop Infrastructure (VDI) initiative. The IT department aimed to transition to virtual desktops to streamline desktop support, patching, and provisioning, thereby reducing administrative overhead. They evaluated new HP servers and SAN storage, Cisco UCS servers with a SAN, and the Nutanix Virtual Computing Platform. The decision to choose Nutanix was driven by its simplicity, converged architecture, high performance, power efficiency, and convenient VM-centric replication.

PEO Aviation needed a high-performance, easy-to-manage server and storage infrastructure to support a production VDI deployment. The existing infrastructure, which included Dell half-height blade servers, an EMC Celerra storage array, and a Fibre Channel SAN, was insufficient for supporting a large number of users. The IT department was tasked with finding faster hardware that could effectively support a VDI environment. They considered various options, including Fusion-io PCIe flash memory cards, new Dell blade servers with an EMC VNX storage array, and a Vblock integrated system from Cisco and EMC. However, these solutions either lacked high availability with failover or were difficult to manage due to the lengthy and unpredictable federal procurement process.

Sanity Music, a leading Australian retailer with 160 stores, faced challenges with slow internet speeds at some regional stores, impacting customer satisfaction. Customers often had to wait several minutes for search results, which was unacceptable for the company. Upgrading bandwidth was not a preferred option due to high costs. The IT department was tasked with finding a solution to improve search performance without significantly increasing operational costs.

IPFS was running VMware Horizon View to provide virtual desktops for its 500+ employees and wanted additional servers and storage for a disaster recovery site. The production VDI environment consisted of four Dell R810 servers with flash storage PCIe cards and a DataCore SAN. The system delivered high performance and responsive user desktops, but lacked high availability. In the case of a serious system failure or disaster, all users would be offline and unable to work. So the firm wanted to establish a secondary site for failover and business continuity. The infrastructure for the DR site did not have to be the same as production – it is virtualized, after all – but it needed to offer comparable performance and the additional benefit of extreme ease of use. VDI is famously demanding of high I/O throughput, so it was important to have a consistent user experience between the production and DR environments. The IT staff also wanted a solution that would be easy to configure and manage.
