Backup Exec Performance and Tuning Guide - Wrong Numbers

[Dead-Data]

Some of the numbers listed in the tables for transfer rate seem wrong. 

Table 1.6

FCoE  36,000 GB/hr !!!

Table 1.7

10GBe  3600 GB/hr Theoretical  2,500 GB/hr Typical

I thought 3600 was Typical from 4500 Theoretical?  Any idea where 2500 GB/hr  is derived from?

Table 1.10

LTO6  Capacity 6.4TB uncompressed & 12,8TB compressed ! 

I thought it was 2.5TB & 6.4TB ?

Can anyone confirm true 'typical values for FCoE on 10GBe, FC 16GB and LTO6 ?

Thanks in advance

Hi,

LTO6 - 2.5TB native, 6.5TB compressed (lab, not real world)

Speeds for 10 GbE: https://en.wikipedia.org/wiki/10_Gigabit_Ethernet

FCoE - 36TB per hour seems a bit excessive.

If you don't come right here, PM Colin Weaver and raise this with him.

Thanks!

Same crazy FCoE numbers are quoted in BEX 2014 Tuning guide as well.

3.6TB/hr theoretical 2.5TB/hr typical is probably "real world"

But would be good to have an accurate Symantec source document to cite for a design I'm working on.

Thanks for pointing this out to us, we are looking to get this guid eupdate with valid figures

As well as the FCoE figures in Table 1-6, we have spotted some other mistakes in table 1-7 and 1-10 as well

With regards to table 1-6 the theoretical should be 1,250 MB/s, 75,000 MB/min 4,500 GB/hour

Hi Colin,

Currently doing some testing of an environment with 10GB FCoE between Storage and VMware Hosts, then 10GB LAN betwen host and Media server and thence to Dedupe appliance.

Throughput being reported as 1,250 MB/min, so means along way short of theoretical currently!
