Using Our Technology
In-depth guides for managing your cloud infrastructure, including the control panel, CPU, memory, storage, networking, backups, security, and the API.
Control Panel
What Are Drives and Servers, and How Do I Use Them?
Drives are persistent storage volumes for your OS, applications, and data. Servers are virtual machine instances. You can attach multiple drives to a single server.
How Many Servers and Drives Can I Have?
There is no hard limit on the number of servers or drives you can create on your Go2Cloud account. Scale your infrastructure as needed.
How Are Servers and Drives Distributed Between Physical Hosts?
Drives are allocated to a randomly chosen physical host with sufficient space. Servers prefer the same host for direct access but use iSCSI when needed.
Options Available When Adding New Instances
When creating a new server, choose from pre-installed images (Ubuntu, Debian), self-install from a CD, boot from a live CD, or boot from an existing drive.
What Do Shutdown, Hard Power Off, and Hard Reset Do?
Shutdown sends a graceful ACPI signal. Hard Reset triggers a non-maskable interrupt. Hard Power Off simulates pulling the power cable.
Do You Provide cPanel, Plesk, or phpMyAdmin?
Go2Cloud servers do not come pre-installed with hosting panels. You have full root access to install cPanel, Plesk, phpMyAdmin, or any other management software.
CPU
What Is Core-MHz?
Core-MHz is the unit Go2Cloud uses to measure CPU allocation. 2100 core-MHz is roughly equivalent to one 2.1 GHz AMD Opteron core.
What Are the CPU Limits for a Single Server?
CPU allocation ranges from a minimum of 500 core-MHz to a maximum of 20,000 core-MHz per server.
How Do I Resize the CPU on My Server?
Resize your server's CPU by clicking 'Edit server' in the control panel and adjusting the core-MHz slider. Changes take effect after a restart.
Can I Change the Number of CPU Cores?
Yes, you can manually set the number of CPU cores through the advanced settings in the control panel, though automatic is recommended for most cases.
Memory
What Are the Memory Limits for a Single Server?
Server memory ranges from a minimum of 256 MB to a maximum of 32 GB RAM. Choose the right amount based on your operating system and application requirements.
How Do I Resize Memory on My Server?
Resize your server's memory through the control panel by editing the server configuration while it is powered off.
Drives (Storage)
What Storage Redundancy Is Offered?
All virtual drives on Go2Cloud use RAID1 disk arrays, mirroring your data across multiple physical disks for reliability.
How Do I Attach Multiple Drives to a Server?
Attach additional drives to your server through the 'Edit server' page in the control panel. Your server supports multiple drives for flexible storage.
Can I Share a Drive Between Multiple Servers?
A single drive cannot be attached to multiple servers simultaneously. Use NFS or Windows file sharing over a VLAN to share files between servers.
What Happens to My Data When a Server Is Shut Down?
Your data is stored on persistent virtual drives and remains safe when your server is shut down. Only processing charges stop when powered off.
How Do I Resize My Disk Drive?
Growing a drive is done through the control panel followed by an OS-level partition resize. Shrinking requires OS-level preparation and coordination with support.
Networking
What Are Your DNS Settings?
Go2Cloud DNS servers are 41.79.108.1, 41.79.111.1, and 8.8.4.4. The default gateway is 41.79.111.1.
How Do Static IP Addresses Work?
Static IP addresses are purchased through subscriptions and allocated to your servers via the control panel.
What Is a Private VLAN?
A private VLAN creates an isolated network between your servers. Traffic over the VLAN is free and does not count towards your bandwidth allowance.
Do You Charge for Network Bandwidth?
Yes, both inbound and outbound traffic are charged. Data transfer totals reset at the beginning of each calendar month.
How Do I Track My Bandwidth Usage?
Your current bandwidth usage is displayed in the control panel, measured in GB with monthly totals that reset automatically.
What Happens If I Exceed My Bandwidth Limit?
Additional bandwidth beyond your subscribed amount is billed at the standard per-GB rate. Your service is not interrupted.
Why Is Some Outbound Traffic Blocked?
Outbound SMTP, FTP, SSH, and Telnet ports are blocked by default on trial and new accounts to prevent abuse. These can be unblocked on request.
How Do I Unblock SMTP for Sending Email?
Contact support@go2cloud.co.za to request SMTP unblocking on your paid account. Include your account details and intended use case.
Uploading CDs and Server Images
How Do I Upload a CD or Server Image?
Upload CD images and server images via SFTP (port 22), the API upload tools, or the web upload form for files under 1 GB.
What Image Formats Are Supported?
Go2Cloud supports raw disk images natively. VMware (.vmdk) and Hyper-V (.vhd) images must be converted to raw format before uploading.
How Do I Convert VMware or Hyper-V Images?
Use the qemu-img tool to convert .vmdk (VMware) or .vhd (Hyper-V) images to raw format for uploading to Go2Cloud.
Backup
What Is Your Backup Policy?
Go2Cloud does not provide an integrated backup service. You are responsible for maintaining your own backup strategy using third-party tools or services.
How Do I Copy a Drive?
Use the drive copy function in the control panel to duplicate a drive while the server is powered down. This creates an exact point-in-time copy.
Security
Do You Offer a Firewall?
Go2Cloud offers a platform-level firewall that can be enabled in your server settings. You can also run software firewalls like iptables or Windows Firewall.
Can Go2Cloud Staff Access My Server?
Go2Cloud staff cannot see your passwords. Staff may view the VNC display to check server health, but they cannot access your data directly.
How Do I Secure or Disable VNC Access?
You can disable VNC access entirely by leaving the VNC password field blank in your server configuration. This prevents all console access.
Using the API
Go2Cloud API Overview
The Go2Cloud API is a RESTful interface for managing your cloud infrastructure programmatically. It uses HTTP Basic Auth and UUID-based resource identifiers.
API Working Example
See a working example of how to use the Go2Cloud API to list servers, create resources, and manage your infrastructure through HTTP requests.
Download Command-Line API Tools
Download ready-made command-line scripts for Linux, Unix, and Cygwin to manage your Go2Cloud infrastructure from the terminal.
