Hey Omid, Before buying any NAS or SAN solution you will need to take in account couple things. Squid has an in memory objects index which requires ram and reduces the amount of in memory objects you can store. You will need to first verify that your current machine memory usage can allow you

Hey Omid, I do not have benchmarks. I was actually in the past looking at GlusterFS and NFS for couple purposes. The Gigabit and 10Gb have their difference. The main big thing is that a simple SATA\SAS jack\connector\port supports up to 6Gb and in most cases the machine will not utilize even 1

Hi Omid, The I/O requirements can be estimated well if you tell more about the environment. If you know the number of requests/second that Squid prcoesses you can add a percentage to increase performance and calculate the desired I/Os per second (IOPS). When you have the desired IOPS, you can ca

How we can test this ? What protocol suggested for Squid ? NFS, iSCSI,... ? Apart from bandwidth, is there any important difference between 1Gbit ethernet and 10G ? Do you suggest me to buy 1Gbit storage and monitor it or you think the money will be wasted ? Any news about this REALLY interesting
