Hyperconverged Infrastructure (HCI) – What’s Included, What’s in It for Credit Unions and Other Financial Institutions — and How to Get Started (Part 2)

by on August 2, 2019

Hyperconverged – What’s Included?

Does a “data center in a box” sound appealing?  Hyperconverged infrastructure is oftentimes referred to in this fashion as after the preliminary cabling and minimal networking configuration, it has all of the features and functionality of the traditional 3-2-1 virtualization architecture (except that single point of failure).

Fast Deployment

Due to its appliance-based architecture, hyperconverged
infrastructure systems can be deployed much more quickly than other
virtualization solutions. Racking and networking are usually the most
time-consuming elements of the implementation. Deployment times differ by
vendor, especially if there is a third party hypervisor to install and VSAs to
configure. But with a native hypervisor pre-loaded, an entire cluster of
appliances can be up and running in under an hour in your financial services
environment.

Streamlined Management

Single pane of glass management, or a single pane view, can be
enjoyed with a hyperconverged infrastructure solution. This stands in stark
contrast  to the multiple management consoles and interfaces necessary in
3-2-1 architectures. Of course, this is not automatically the case for
hyperconverged infrastructure solutions using third-party hypervisors which
typically end up using two interfaces. For hyperconverged infrastructures with
a native hypervisor included, this single interface tactic dramatically
decreases management time and effort and streamlines management tasks for the
administrator.

Backup and Disaster Recovery (DR)

In order to help eliminate yet another vendor from your IT
environment, backup and disaster recovery (DR) are often times included at no
extra cost in hyperconverged infrastructure solutions. And really, backup,
failover, failback, and DR should be a part of every IT environment.
Consequently, it makes perfect sense to include these features natively in
hyperconverged infrastructure solutions. Unlike third-party solutions, native
solutions are typically embedded in the storage layer and allow innate
awareness of block changes for cleaner backup, replication and recovery
options.

Clustering for High Availability

While a hyperconverged infrastructure can many times be deployed
as a single appliance for selected use cases, it is commonly architected as a
cluster of appliances for high availability. Hence, not only can an appliance
absorb the loss of a disk drive, but the cluster can absorb the loss of an
entire appliance. Clustering also enables the hyperconverged infrastructure
system to scale seamlessly by adding additional appliances to the cluster. Some
hyperconverged infrastructure solutions require clustering appliances of the
same model and configuration, while others allow clustering of heterogeneous
appliances.

Software and Hardware Updates

Conducting regular system software and firmware updates can be a
dreaded task in financial organizations. But, hyperconverged infrastructures
can make this process easy. By owning the entire virtualization, server, and
storage stack, and operating in a highly available cluster, updates can be
performed automatically across the entire cluster. All software layers
(hardware firmware, hypervisor, storage, and management) can be upgraded
simultaneously as a single, fully tested system to eradicate component compatibility
concerns. VMs can be automatically moved from appliance to appliance in the
cluster as updates are made to keep all systems operational. hyperconverged
infrastructure can eliminate downtime and headaches when performing updates.

Lower Total Cost of Ownership (TCO) 

A hyperconverged infrastructure may not always be the lowest cost
solution in terms of the initial capital investment―although it often is due to
the ease of scalability which enables organizations to purchase only the needed
appliances and does not require excessive over-provisioning in the initial
investment. Buying only what you need, when you need it, can lead to dramatic
savings. In addition to capital savings, a hyperconverged infrastructure
provides considerable operational savings over time as well, by greatly
reducing the costs of management and maintenance. Simplifying an IT environment
with a hyperconverged infrastructure can save over 50 percent in the total cost
of ownership over 3-2-1 solutions.

 So, What’s In It for Financial Services Organizations?

Hyperconverged Infrastructure is designed as a replacement for
3-2-1 architecture to eliminate excess cost and complexity. Therefore, it can
benefit any size financial services organization that requires a robust
virtualization environment. However, the extreme simplicity of a hyperconverged
infrastructure makes it highly beneficial in use cases where IT staff is
limited, for instance smaller branch offices and credit unions. Small and
medium business (SMB) and distributed enterprises with many remote offices or
branch offices (ROBO) typically have staffing issues that make a hyperconverged
infrastructure an ideal choice.

For a small to mid-sized financial organization, the entire IT
staff may be as small as only one full-time or even part-time IT administrator.
The complexity of a 3-2-1 architecture can be extremely troublesome. It can
require levels of training and certification that push the cost of qualified
administrators out of reach. The simplicity of a hyperconverged infrastructure,
in turn, can allow it to be managed easily by a junior administrator. Or, it
can mean that a more senior administrator can spend less time managing the
infrastructure and more time delivering better applications and services that
positively impact the bottom-line.

In a distributed financial services organization, remote offices
and branch locations seldom possess dedicated IT staff. These remote locations
often require frequent visits from IT staff which can result in high travel costs
and lower productivity. The simplicity of a hyperconverged infrastructure
includes multiple redundancies for HA, failure handling, and self-healing. A
failed drive at a remote site does not lead to an outage and does not require
immediate replacement (nor the risk of business, legal and/or regulations
non-compliance consequences). Greater uptime and accessible remote monitoring
and management lead to lower travel costs of IT staff to these locations and
significantly lower operating costs (OpEx)―not to mention the increase in
productivity.

Ready to Get Started?

Hyperconverged infrastructure offers credit unions and other
financial services organizations a straightforward, highly innovative and
affordable path to digital transformation. A transformation that enables great
leaps forward in capabilities and management ease, while dramatically reducing
overall costs.  But where to begin? My recommendation is to start by doing
a bit of homework. You can start by asking potential vendors the following
questions:

• Does the solution provide a native hypervisor or does it require
an additional purchase of hypervisor licensing and support?

• Does the solution offer hypervisor-embedded storage or does it
use virtual storage appliances (VSAs)?

• Can the solution combine and scale with dissimilar appliance
models and configurations?

• Does the solution offer native backup and DR capabilities?

• Does the solution integrate with cloud computing? How?

The Next Logical Step

Credit unions, together with virtually all other financial
institutions, are challenged with ensuring  remote, branch locations
deliver top quality services to their clients. Today’s customers expect instant
access to data and on-demand IT services at every location. Infrastructure,
including servers, storage, virtualization, and disaster recovery (DR) can be
both costly and complex using traditional methods. 

As the credit union banking and the overall financial services
industry and its associated compute requirements continue to evolve, hyperconverged
infrastructure is the next logical step in on-premises and cloud-integrated
virtualization infrastructure. Standing still with more traditional
virtualization solutions like the 3-2-1 architecture may end up costing
organizations far more in capital, manpower, and training, than moving on to
the dramatically increased capabilities, simplicity and cost savings of a
hyperconverged infrastructure solution.
