1.8 12: Iscsi Cake

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).

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.

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. iscsi cake 1.8 12

4/5 stars
The iSCSI Cake 1.8 (12‑drive/12Gb/s) is a dependable, no‑surprises block storage appliance. Ideal for hypervisor hosts, database logs, and backup targets. Avoid if you need synchronous replication or a silent chassis. For the price, it’s a “cake” you can both eat and serve.

If you meant something else by “1.8 12” (e.g., 1.8 TB capacity, 12 GbE ports, or a different model), let me know and I’ll adjust the review. You ship transaction logs to a DR site

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.

Your Linux iSCSI initiator (/etc/iscsi/iscsid.conf) needs tuning to survive CAKE: If you meant something else by “1

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.

The 1.8 version is notable for balancing functionality with a small resource footprint. Key features typically include:
