[font=arial,helvetica,sans-serif]I have 2 x AMS2100 box with 48 TB useable capacity. PROD and DR. From the Production, we breaked into the following LUNs:[/font]

[font=arial,helvetica,sans-serif]LUN0: 2 TB[/font]
[font=arial,helvetica,sans-serif]LUN1: 2 TB[/font]
[font=arial,helvetica,sans-serif]LUN2: 2 TB[/font]
[font=arial,helvetica,sans-serif]LUN3: 800 GB[/font]
[font=arial,helvetica,sans-serif]LUN4  2 TB[/font]
[font=arial,helvetica,sans-serif]LUN5: 7 TB[/font]
[font=arial,helvetica,sans-serif]LUN6: 2 TB[/font]
[font=arial,helvetica,sans-serif]LUN7:  4 TB[/font]
[font=arial,helvetica,sans-serif]LUN8: 10 TB[/font]
[font=arial,helvetica,sans-serif]LUN9: 10 TB[/font]

[font=arial,helvetica,sans-serif]We were able to replicate LUNs 0,1, 7, and 8 via TrueCopy Extended on a 1 GE link iSCSI (back to back)... until we encountered error message [/font][font=arial,helvetica,sans-serif]about the supported capacity for the installed cache...[/font]
[font=arial,helvetica,sans-serif]Does it mean that the AMS2100 lacks the required cache size for replication?[/font]
[font=arial,helvetica,sans-serif]Is it true that AMS2100 only supports up to 12.xx TB? [/font]

[font=arial,helvetica,sans-serif]What are your recommendations? [/font]
