Hyper/Converged the “Hitachi Way”

Blog Post created by Sean Siegmund Employee on Dec 14, 2018


It’s time to modernize your IT infrastructure, and your team is looking to collect the information needed to select the right foundation that fits your strategic business needs. The ideal solution optimizes existing applications and operates CapEx and OpEx efficiently.   Not all your IT systems will transfer to any cloud platform today, but leaving the systems stuck in a traditional IT infrastructure will mean more headaches to come. Converged Infrastructure (CI)and Hyperconverged Infrastructure (HC) solutions have what you need to manage the day-to-day IT operations and allow you to tackle tomorrows challenges efficiently. The decision on your hands will require a balanced approach to support many of the different workloads and applications living today on your data center floor.

With these needs in mind, Architects at Hitachi Vantara have built a set of UCP solutions targeted for hyperconverged and converged solutions.  These infrastructure solutions utilize the same core hardware components and leverage the same management and automation tools. With these solutions, you can now have workloads fit onto the underlying hardware they will require to keep the IT systems highly available while still being able to meet the performance demands of the business.

Converged Versus Hyperconverged

The popularity of both of these technologies’ rests with the fact that both solutions make it easier for administrators to interact with the underlying hardware. The essential difference between CI and HC is how the storage and network components are deployed and utilized. These solutions utilize virtualization, the same compute CPUs and memory, and they both utilize disks in a hybrid (flash and non-flash) or all flash form. Hyperconverged (HC) Infrastructures, however, use local direct attached storage (vSAN), along with software-defined storage and networking. You can manage all resources from a single administration pane; this includes the hypervisor (virtual) and hardware (physical) elements. Hyperconverged Infrastructure solutions operate in a flat architecture, where the compute nodes are handling the bulk of the work including all storage capabilities.

Converged Infrastructure (CI) combines compute, storage and network as a single resource. The elements are pre-defined by the hardware vendor and can also include automation and orchestration management software. The storage sub-system connects to a SAN and supplies storage to the compute infrastructure. When using Hitachi Enterprise storage, memory DIMMs within the storage platform are caching all I/O, and the storage array is capable of 32 Gb FC speeds per port.

The focal point with these two technologies comes down to a few aspects - are your compute resources budgeted to do specific clustered workloads, or do you need infrastructure that will have dedicated components for the network and storage layers? Can the business benefit from a self-service model, or will the mundane tasks of today be benefited by the orchestration of a CI solution?

CI and HC solutions have a various number of trade-offs and benefits, but everyone should evaluate these infrastructure solutions on an organizational and divisional basis when attuning HC servers for a given workload. The workloads running within an HC environment should have the same characteristics to share the HC resources properly. Otherwise, competing workloads can be migrated to another HC cluster. HC will allow end users to properly test and tune developmental tasks without the need for significant interaction with HC infrastructure administrators. HC allows IT departments and stakeholders to deploy on-demand with a tailored HC platform while enabling a common administration framework across all HC solutions implemented.

Conversely, CI solutions embrace many different workloads due to the features of an Enterprise Storage system and other hardware components.  Within a virtualized environment, CI accelerates hardware deployment of new systems and increases performance and resource utilization. With a CI system, you can rest assured that the system is ready to function with no interoperability pitfalls.  CI systems are a set of resources which can be provisioned across multiple divisions while using a qualified hardware platform common for IT resources.

Hitachi has a proven track record of deep expertise in striking the right balance within each of these platforms, cementing again the need to have a partner with expertise in the right fit for your business and not specialized in any particular infrastructure. As part of your digital transformation, do you have a partner skilled in positioning the best overall infrastructure solution to meet your business needs?

Hitachi UCP HC

The Hitachi Unified Compute Platform (UCP) for HC is a set of compute nodes which have been approved by VMware to run as a vSAN ReadyNode configuration. Hitachi utilizes DS120, DS220, and DS225 models as the compute resource for Hitachi UCP HC platform.  Several configurations have certified ranging from HY4 – HY8 to AF4 – AF8 series. With the various contributions, Hitachi has made available a wide range of offerings that will match the specific workload which the platform needs to handle.

A vSphere cluster comprised of vSAN ReadyNodes is closely tied to ESXi versioning and other software related components from VMware. All of the Hitachi UCP HC configurations allow for SSD cache and your choice of a hybrid solution using SATA or an all-flash solution within the capacity tier. Within the UCP HC solution, the use of NVIDIA GPUs is also available, allowing for improved performance of high demand workloads.

In September 2018, the Hitachi UCP HC solution included an important emerging technology, which is sure to be part of the future of all modern-day Datacenters. NVMe is a fast data access protocol, improving performance flash and other non-volatile storage devices. It debuts within the Hitachi UCP HC platform and will be rolled out into all of the Hitachi Storage Product Line starting 2019. For more information about the UCP HC All-NVMe solution, please see the following links.
