Iscsi Cake 1.8 12 -
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
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: iscsi cake 1.8 12
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 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 iSCSI Cake 1
: 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
(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
Here are the most likely interpretations and an explanation for each, so you can clarify which direction you need.
Use Case 3: Hyper-V Live Migration over LTE
A backup LTE modem provides a 1.8/12 failover. CAKE allows iSCSI storage traffic to remain alive (though slow) during a primary link outage, saving your VMs from blue-screening.
Step 5: Testing the Stack
Use ping to monitor latency under load:
# From initiator to target IP
ping -c 100 <iSCSI-Target-IP>
Simultaneously run:
dd if=/dev/zero of=/mnt/iscsi_lun/test bs=1M count=100
Without CAKE, ping will exceed 500ms. With the "1.8 12" cake command, latency should stay under 80ms.
iSCSI Cake 1.8 – 12‑Drive/12Gb/s Review
What is iSCSI Cake?
At its core, iSCSI Cake acts as an iSCSI (Internet Small Computer System Interface) target server. It allows a server machine to export disk images (virtual hard drives) over a standard IP network to client computers. To the client computer, the remote image appears and functions exactly like a local physical hard drive.
1. Possible typo / mixed context: iSCSI + Cake (traffic shaping) + kernel version?
- iSCSI = Internet Small Computer System Interface (storage networking protocol).
- Cake = Common Applications Kept Enhanced (a Linux traffic shaping/queue discipline,
sch_cake). - 1.8.12 = Could be a kernel module version or package version.
If you meant: “iSCSI performance shaped by Cake (1.8.12) on Linux”
Possible piece:
“Using Cake 1.8.12 to Prioritize iSCSI Traffic” — A technical note where
sch_cakelimits iSCSI to 12 Mbps or uses diffserv8 for storage traffic. Example CLI:
tc qdisc add dev eth0 root cake bandwidth 12mbit diffserv8
Step 4: iSCSI Initiator Tuning for 1.8/12
Your Linux iSCSI initiator (/etc/iscsi/iscsid.conf) needs tuning to survive CAKE:
node.conn[0].timeo.noop_out_interval = 5
node.conn[0].timeo.noop_out_timeout = 10
node.session.timeo.replacement_timeout = 15
node.session.iscsi.FirstBurstLength = 8192
node.session.iscsi.MaxBurstLength = 131072
node.conn[0].iscsi.MaxRecvDataSegmentLength = 4096
Why? With CAKE enforcing 12Mbit upload, larger bursts (default 262144 bytes) will be queued, violating iSCSI’s expected latency. Use Case 3: Hyper-V Live Migration over LTE
