“Using Cake 1.8.12 to Prioritize iSCSI Traffic” — A technical note where sch_cake limits iSCSI to 12 Mbps or uses diffserv8 for storage traffic. Example CLI:
tc qdisc add dev eth0 root cake bandwidth 12mbit diffserv8
The 1.8 branch, solidified by Build 12, introduced several features that are now standard in SDS but were revolutionary at the time: iscsi cake 1.8 12
Before setting 1.8 and 12, verify via speedtest-cli. Due to overhead, your real usable might be 1.6 Mbps down / 11 Mbps up. CAKE works best if you set it to 95% of measured value to absorb micro-bursts.
During the era of the 1.8 branch, virtualization was shifting from a luxury to a standard. VMware ESXi and Microsoft Hyper-V were battling for dominance, but both shared a common weakness: shared storage was expensive. SANs (Storage Area Networks) cost tens of thousands of dollars, creating a barrier to entry for High Availability (HA) clusters. # On iSCSI initiator's outgoing interface tc qdisc
StarWind 1.8 entered the market as a solution to this "Shared Storage Gap." Build 12, specifically, was a refinement build. It focused on stability and the synchronization engine that allowed two physical servers to mirror their local storage and present it as a single iSCSI target to the hypervisor.
If you run iSCSI over a raw 1.8/12 link without shaping, you experience bufferbloat. Your router’s buffer fills, latency spikes to 2000ms+, and the iSCSI initiator drops the session. Standard tc (Traffic Control) with htb fails because: “Using Cake 1
This is where CAKE wins. The string cake 1.8 12 in your search implies you want to set tc qdisc with CAKE’s bandwidth parameter to match your ISP’s actual throughput.
The iSCSI Cake 1.8 is a mid‑range storage appliance targeting SMBs and remote office workloads. It combines an iSCSI target with lightweight caching and thin provisioning. The “12” likely indicates 12 hot‑swap bays (2.5” or 3.5”) and 12 Gb/s SAS backplane support.
