DHS Pegasus

Why choose
DHS Pegasus
as your cloud solution?

 

3rd party-verified fastest network backed storage globally

The technology behind DHS Pegasus was deemed the fastest network backed storage globally by review site CloudHarmony.com in a comparison of over 50 IaaS providers globally, providing storage that is 60% faster than a dedicated server with 15K SAS disks.

 

No CAPEX or maintenance costs

Purchase, installation and integration costs of in-house architecture are significant, both in terms of physical hardware and staff time required. DHS Pegasus provides everything you need almost instantly and DHS can maintain your infrastructure on your behalf.

 

Pay only for what you use

Our ‘pay-by-the-second’ pricing structure ensures you pay only for the time utilised, unlike other leading cloud service providers. DHS Pegasus allows you to fire up servers and resources on an as needed basis. If entering a test phase or high-traffic period, simply ‘switch on’ the resources you need (i.e. server, storage, memory etc.) and start working. Once your test phase or high-demand period is complete you can shut down the resources that you no longer need.

 

99.9% uptime

With a no-single-point-of-failure design your data is stored on your virtual machine AND replicated elsewhere in the cluster. If a node fails, your virtual machine will be immediately restarted elsewhere with almost no downtime. This is why we can offer market leading SLAs and SAAs.

 

Powered by Infiniband

Found in supercomputers (read: the Large Hadron Collider), Infiniband is the industry-leading interconnect providing the highest bandwidth, lowest latency, low CPU overhead and low power consumption.

 

More time for your business

DHS Pegasus allows you to virtualise and instantly deploy your infrastructure, giving you more time to focus on your core activities rather than trying to manage a complete infrastructure stack.

 Technical Details

Cloud Platform


DHS Pegasus is a custom built, high performing Infrastructure-as-a-Service (IaaS) platform. DHS Pegasus utilises the latest in virtual machine technology, the Xen hypervisor, running on a custom distribution of Linux and backed by a high-performance Distributed Storage Area Network (DSAN).

The technology behind DHS Pegasus has been built with a no single point of failure (SPOF) design, incorporating hardware from Dell, Cisco, Mellanox and Supermicro.

DHS Pegasus comprises a fully homogeneous, horizontally scaling cluster of servers. Each server is supported by dual 20gb/s Infiniband connections, allowing for point to point traffic between each of the nodes in the cluster to reach 40gb/s.

The environment consists of a homogeneous cluster of servers, though each has slightly different specifications according to the amount of memory in each server and time of acquisition. The ratio of CPU clock cycles to amount of memory is equal in each server.

For the purposes of greater availability, all servers are connected to redundant Infiniband and Ethernet switches.

DHS Pegasus supports the deployment of Linux and Windows templates for the purposes of the orchestration layer, including the cloning of disks and the attaching of multiple IPs/Disks to each instance.

DHS Pegasus offers:

 An easy to use web interface

  • API and CLI utilities (Linux)
  • A cluster with steady state failures
  • Automatic reprovisioning of servers in the event of a hardware failure
  • N+1 redundancy on all storage blocks

Network


N+1 redundancy is offered on all network layers, including our Storage Infiniband network and Ethernet customer network.

All instances have both an interface connected to the public Internet, as well as another providing a per account private network between instances. Each instance has the ability to communicate to other instances over Ethernet feeds ranging from 1 Gigabit to 10 Gigabits.

From a public internet perspective the DHS Pegasus data centre has several high quality upstream providers (up to several hundred Mbps) and peering connections (>1Gb/s). Routes are defined via Vocus Networks and Equinix Connect (a mix of Telstra/Optus/Verizon). Furthermore, we heavily peer with Equinix peering and Pipe IX.

All routers are arranged in an N+1 redundant fashion, with VRRP failover of gateway IPs and BGP failover of transit feeds.

Security


Dark Horse Systems takes a very serious approach to security with all our service offerings, and DHS Pegasus is no exception. Access to servers is controlled by a multi-layer security model, and access to infrastructure is granted solely by connecting through a secure VPN tunnel. Furthermore, all management activities are carried out over a completely separate network from customer/Public internet traffic.

In terms of physical security, all equipment is stored in a private cage in Equinix Sydney3. The site is protected by biometric security control and 24-hour on-site security.

Facilities and SLA


The Sydney3 data centre offers a full range of premium colocation, interconnection and support services to a wide range of secure digital ecosystems built by networks, enterprise, content, cloud and IT services companies and financial institutions.

The data centre and infrastructure behind DHS Pegasus boasts the following SLAs:

  • 99.999%+ Power availability
  • 99.9%+ Temperature and humidity control availability
  • 99.99%+ Cross Connect availability

Some of the key features of the Sydney3 data centre facility include:

  • Complete N+1 redundancy on all power and cooling tiers
    (chillers, CRAC Units, UPS Systems, Generators)
  • 24 hour on-site security and CCTV recordings
  • VESDA smoke detection and fire suppression systems
