Why Purchase Resources?

Koa is free to use for all students, faculty and staff at any of the campuses in the University of Hawaii system.

While a significant amount of work can be completed using free community resources, some researchers may find that they need more storage or dedicated resources to run longer jobs than the community nodes allow or they find the wait times for community resources to significantly impede their research.

Faculty and staff can purchase or lease compute nodes to power their research and select a long term storage solution for their data.

Computational resources

Researchers have the options of purchasing or leasing computational resources on Koa. Both options provide the following benefits:

A private scheduler partition
Priority access to those that have been granted access to the lab private partition
- Private partition jobs will have immediate access compared to community users
Maximum of a 30-day job run time

Purchasing computational resources (Hardware)

Pre-configured & Custom System Options

When purchasing resources to add to Koa, researchers are able to choose from a set of pre-configured systems that the Information Technology Services Cyberinfrastructure (ITS-CI) team has curated and acquired estimated pricing for.

Pre-configured systems

In some cases, these systems may not meet a researcher's specific needs. In this case, the ITS-CI team is willing to work with the researcher to try and configure something custom that will work with Koa and work for the researcher.

Fiscal & End of Life Options

Purchasing computational resources has two different fiscal components to it. (1) The majority of the cost is classified as equipment, while (2) a small amount of the cost will be classified as a service. The hardware being purchased is not something unique to Koa, allowing researchers the freedom to utilize the hardware outside of Koa after it is used on Koa if they so choose, but the service fee we charge is used to pay for the use of the small amount of networking ports, cables, and data center infrastructure your need would need to live 5 years as part of Koa. Computational resources purchased by a researcher would have three different options once it has been part of Koa for 5 years. The end of life options of (1) Pay to Stay, (2) Donation, and (3) Removal are described here: Computational Resources End of Life

Purchasing Process

This full purchasing process for nodes on Koa can be found here: Node purchasing process, and the node purchasing intent form can be found here: Node purchasing intent form.

Leasing computational resources (Service)

In some cases, a researcher needs a short period of dedicated access to hardware on Koa or cannot spend a large amount of funds at once. In this case, a service model for leasing computational resources is available to researchers.

Due to the limited supply of GPUs in Koa, we do not currently lease GPU nodes

Nodes for lease can range from 128 GB of RAM with 20 cores up to nodes that have 1.4 TB of RAM with 190 cores. Our pricing model is as follows:

		CPU		Networking
Node Type	Memory	Cores	type	Ethernet	MPI (Infiniband)	Cost per month
Basic - Legacy	128GB	20	Intel Ivy-Bridge	1 Gbit	No	$110
Basic	160GB	20	AMD Genoa	50 Gbit	Yes (200 Gbit )	$167
Large memory	480 GB	60	AMD Genoa	50 Gbit	Yes (200 Gbit )	$501
XL memory	960 GB	120	AMD Genoa	50 Gbit	Yes (200 Gbit )	$1,002
2XL memory	1.4 TB	190	AMD Genoa	50 Gbit	Yes (200 Gbit )	$1,586

Storage Resources

Please note: sensitive/restricted data cannot be stored in our storage resources.

Contact uh-hpc-help@lists.hawaii.edu for sensitive/restricted data storage solutions. See the UH Institutional Data Governance Data Classification Levels for more info.

Lab Storage (Free)

This option is free to each lab at UH with members that utilize Koa. We allow a lab to request a single 500GB storage location for free. To request lab storage, please fill out the following form and ITS-CI will be in contact.

Lab Storage request form

KoaStore (Service)

When a lab exceeds what storage is freely available on Koa, they will want to consider purchasing additional storage on Koa for the lab. The KoaStore storage option can be dialed up and down based on a labs need.

Storage Amount	Files Allowed	Access control	Cost per year
1 TB	1,048,576	Koa Account + Linux Poisx Group	$50

KoaCloud (Service)

For labs with storage needs larger than Google Drive can fulfill or have a need to allow public links for downloads or anonymous/password protected upload pages for research data, KoaCloud may meet your requirements. Koacloud utilizes the Nextcloud software, which provide a self hosted product similar to Dropbox.

Storage Amount	Access Control	Cost Per year
1 TB	UH Credentials + Nextcloud Teams	$55

For labs that are interested in Koacloud, they may visit the following link to learn how to order this service.
