E1 Series Nodes

E1 Series Nodes Overview​

The E1 Series offers enhanced cost efficiency, flexible scaling, and improved network throughput—ideal for both development and production workloads.

With smart billing behavior, optional public IPs, and audit-friendly features, E1 nodes give you better control over your compute environment.

Key Capabilities​

Stopped Billing Optimization​

  • Billing for the compute portion of a node automatically pauses when stopped.
  • Billing resumes when the node is powered back on.
  • Storage and attached resources (e.g., volumes, IPs) are billed continuously, regardless of node state.

Smart Plan Management​

  • You can modify your plan (vCPU/RAM) only while the node is powered off.
  • You can both upgrade or downgrade your plan.
  • UI option renamed from “Upgrade Plan” to “Modify Plan” for better clarity.

Public IP: Optional by Design​

  • Nodes are launched without a default public IP.
  • You may attach a public IP any time after node creation.
  • Node launch even if no public IP and no VPC is configured.

Storage Flexibility​

  • Base storage is not included in the plan.
  • Users must select disk size during launch.
  • Disk size can be increase after launch.
  • Additional volumes can be added later as needed.

IOPS Calculation for Root Storage​

The IOPS calculation is simple:

New IOPS Value = Old IOPS Value + (Change in Root Disk Storage × 5)

As you add more storage, your I/O performance increases proportionally, enabling efficient handling of higher read/write operations.

Example​

For a root storage size of 150 GB:

  • Read IOPS = 15000
  • Write IOPS = 10000

When increasing root storage to 250 GB:

  • Change in storage = 250 GB - 150 GB = 100 GB
  • Increment in IOPS = 100 × 5 = 500
  • New Read IOPS = 15000 + 500 = 15500
  • New Write IOPS = 10000 + 500 = 10500

Summary Table​

Root Storage (GB)Read IOPSWrite IOPS
1501500010000
2001525010250
2501550010500
3001575010750

Network Performance​

  • Private Network: Up to 100 Gbps throughput.
  • Public Network (when public IP is attached): Up to 10 Gbps throughput.

Transparent Logging​

  • Audit logs are maintained for:
    • Power and Stopped state transitions include powering on, powering off, and stopping events.
    • Plan modifications
    • Configuration changes
  • Billing history is available to help with usage reporting and cost analysis.

What You Can Do​

  • Stop a node to pause billing (except for storage/add-ons)
  • Modify a plan when the node is powered off and on an hourly plan
  • Launch nodes without a public IP and or VPC
  • Attach a public IP after creation
  • View billing history and audit logs from the UI

Limitations to Know​

  • You cannot modify a node once it is running.
  • You must select root storage before launching a node.
Note

Currently project transfer option for E1 series is disabled.

Increase in Root Storage Size.​

  • The user can create an E1 series node using a root storage size from 75 GB to 2400 GB.

  • 150 GB is the default root storage size of the E1 series node.

  • When the user selects a root storage size less than 150 GB, the IOPS remains the same for all sizes below 150 GB.

  • When increasing the root storage size from 75 GB up to 150 GB, the increment will be in steps of 25 GB (e.g., 75 GB, 100 GB, 125 GB, 150 GB).

  • After 150 GB, the plans will increase in multiples of 50 GB (e.g., 150 GB, 200 GB, 250 GB, and so on).

  • When the user clicks on Increase Root Storage Size, a new drawer will open showing the current root storage plan.

  • Once the user initiates the new root storage size, the node will move to the Upgrading state. After the root storage size is updated, the node will return to its previous state (i.e., if it was in Running, it will return to Running; if it was Powered Off, it will return to Powered Off).

  • Click on Actions section of E1 Series Node and then click on Increase Root Storage button.

Save Image Action

  • A new drawer will open displaying the current root storage plan.

  • Now select the new Root Storage Size and then click on Upgrade Storage button.

  • Once the new root storage update is initiated, the node will enter the Upgrading state. After the root storage upgrade is completed, the node will return to its original state (i.e., if it was previously in Running, it will come back to Running; if it was in Powered Off, it will return to Powered Off).

  • Once the root storage is upgraded, the node will return to its previous state.

Note
  • Currently, we are not allowing the user to increase the Root Storage Size when the node is in the Stopped state.
