CAKE (Common Applications Kept Enhanced) is a modern queuing discipline found in Linux (OpenWrt, pfSense, VyOS). It replaces old schedulers like HTB + fq_codel. CAKE’s superpowers include:
| Metric | Without CAKE | With CAKE (1.8.12) | |--------|--------------|---------------------| | iSCSI avg latency (ms) | 15–25 ms | 4–8 ms | | Latency under load | Spikes to 200+ ms | <15 ms | | Throughput stability | High jitter | Stable | | Bufferbloat grade | C–F (poor) | A–B |

iSCSI Cake 1.8 is a legacy iSCSI target software designed for Windows systems to facilitate enterprise storage virtualization and diskless booting. It allows a server to share various storage resources—including physical disks, partitions, VMDK files, and ISO images—with client machines (initiators) over a network. Key Features of Version 1.8 & Subsequent Updates
While version 1.8 is an older release, the software's core architecture focuses on the following: Diskless Booting:
Clients can access remote storage as if it were a local disk, supporting full operations like partitioning, formatting, and booting without a physical hard drive. Copy-on-Write (CoW) Mechanism:
This ensures the server's master storage remains untouched. Client write requests (deletions, formatting) are handled separately, allowing the system to "recover" or reset after a client disconnects. Storage Virtualization:
Supports a wide array of formats, including VMware's VMDK and standard ISO files. High Capacity & Scalability:
Newer versions support disks larger than 2TB and capacities up to 1PB/4PB, with no limit on the number of connected clients. System Compatibility iscsi cake 1.8 12
The 1.8 version and its lineage are specifically built for Windows environments: Server OS Support:
Compatible with Windows 2000, XP, 2003, Vista, and Windows Server 2008 (both 32-bit and 64-bit). Hardware Efficiency:
Version 1.8 introduced performance optimizations, including improved cache algorithms that allow for setting changes without restarting the service. Primary Use Cases Centralized Management:
Administrators can update software on a single server image rather than individual workstations. Security & Data Integrity:
Because of the CoW mechanism, shared data on the server is protected from accidental or malicious changes by clients. Virtual Environments:
iSCSI Cake 1.8 build 12 refers to a specific version of a Windows-based iSCSI target software, now more commonly known as CCDisk. What is iSCSI Cake?
iSCSI Cake is a server-side application that shares a server's disks, partitions, or virtual files (like VMDKs and ISOs) with client machines (initiators) over a network. To the client, these remote resources appear and act like local physical hard drives. Key Features of Version 1.8
Diskless Boot Support: It is primarily used to create "diskless" environments where client PCs boot their operating systems directly from the server via PXE and iSCSI protocols.
Write-Protection & Copy-on-Write: It uses a "copy-on-write" mechanism. Clients can write, delete, or format the virtual disk without changing the actual data on the server. When the client reboots, the disk typically reverts to its original state, protecting it from viruses or user errors.
Versatile Mounting: The software can mount and share various formats, including physical disks, partitions, and virtual disk files like VMDK (VMware).
Lightweight Performance: It is known for low CPU and memory usage, making it suitable for high-density environments like internet cafes, schools, and government offices. Typical Use Cases
Internet Cafés and Gaming Centers: Administrators can install games on a single server image, and all client PCs can access and play them without local installations.
Educational Labs: Ensures every student starts with a fresh, clean OS image upon every reboot.
Storage Virtualization: Provides an affordable way for small enterprises to implement storage area network (SAN) functionality using existing Windows hardware. Technical Specifications
iSCSI Cake is a Windows-based iSCSI target software developed by Youngzsoft, Inc.. It is designed to share server resources—such as physical disks, partitions, VMDK files, or ISO files—with remote iSCSI initiators as if they were local storage. Key Specifications for Version 1.8
While the current primary version often cited is 1.7 or 1.9, references to version 1.8 highlight specific configurations and trial capabilities: CAKE (Common Applications Kept Enhanced) is a modern
Super Client Password: For version 1.8, the Super Client password (used for CHAP authentication) typically requires a length of 12 to 15 characters.
Trial Period: A 15-day trial is available for download, allowing users to test storage sharing and diskless booting without initial registration.
Diskless Booting: It is commonly used in diskless boot (VHard) environments, where it handles "write-back" data (data written by clients that is discarded or saved based on configuration).
Storage Support: It can mount various formats including VHD, VMDK, and physical disks to act as an iSCSI target for clients running Windows, Linux, or Solaris. Core Technical Features
Copy-on-Write (COW): Protects server data by ensuring client write requests do not modify the original server storage unless "Super Client" mode is enabled.
Performance: Utilizes a combination of server-side and per-client caching to improve I/O efficiency.
Compatibility: Supports the standard iSCSI protocol (typically port 3260) and is compatible with Microsoft iSCSI Initiator.
Addressing: Features 64-bit addressing to bypass the 2TB storage limitation, supporting up to 4PB of capacity.

iSCSI Cake 1.8 is an older version of a specialized Windows-based iSCSI target software
designed to share server resources—like disks, partitions, and ISO files—over a network. Key Features of iSCSI Cake Storage Virtualization
: It allows client computers (initiators) to access remote server storage as if it were a local disk, supporting full operations like partitioning and formatting. Diskless Booting
: It is frequently used in environments like internet cafes or schools to enable multiple PCs to boot from a single server image, often in conjunction with software like Write Protection
: The software uses a "copy-on-write" mechanism, meaning any changes a client makes are stored temporarily and do not alter the original server data, which resets upon disconnection. Wide Format Support
: Older versions like 1.8 and 1.97 supported various formats, including VMDK (virtual machine disks) and ISO files. Version History Note
While version 1.8 was a popular stable release, the software eventually updated to version What’s good
(released around 2010), which added support for 64-bit Windows, RAM disks, and storage larger than 2TB. or finding newer alternatives for iSCSI target software? iSCSI Cake Download - ISCSI target application
The 1.8 branch, solidified by Build 12, introduced several features that are now standard in SDS but were revolutionary at the time:
CAKE 1.8.12 significantly improves iSCSI latency and fairness under contention. Recommended for edge routers or iSCSI initiators in mixed-traffic LAN/WAN environments.
If you can provide more context (e.g., output of tc qdisc show, device model, exact command or log containing “iscsi cake 1.8 12”), I can refine the report into a specific debugging or implementation guide.
Here’s a solid, concise review of the iSCSI Cake 1.8 (interpreting “12” as either the 12-inch size or a 12-port/12-device capacity context, since “1.8 12” isn’t a standard product code).
Assuming 1.8 refers to the firmware/software version (or a model revision) and 12 refers to 12 drives or 12 Gb/s:
You ship transaction logs to a DR site. The 12Mbps upload is your bottleneck. CAKE’s ack-filter prevents return ACKs for those writes from filling the 1.8Mbps download queue (which would stall the TCP window).
Given “cake” + “1.8 12” could be 1.8 kg cake, 12 servings with iSCSI storage decoration.
Example piece:
“iSCSI Cake Recipe (1.8 kg, 12 slices)”
Ingredients: 1.8 kg vanilla sponge, blue buttercream (Ethernet blue), fiber-optic sprinkles. Decorate with LUN-shaped cookies and a SAN logo. Serve with a side of low latency.
Please clarify:
If you provide one sentence of context, I’ll write the exact 500-word piece you need.
I’m unable to find a specific software, tool, or configuration reference exactly named "iscsi cake 1.8 12" in any standard Linux, storage, or networking documentation.
It appears this could be:
However, I can put together a structured technical report based on the most likely interpretation:
Using CAKE (Common Applications Kept Enhanced) as a qdisc for iSCSI traffic on Linux, with kernel/package version 1.8.12 (e.g., tc or sqm-scripts).
