The information on p. 57 "Table 3-1 Speed and distance of Fibre Channel media types" are outdated, does not include MMF OM3, OM4; FC 8Gbps and FC 16Gbps.

Chapter 1.1 'What a network is?'

How about 'What is a network?'

Page 36 section "UNIX-based servers", 2nd paragraph refers to SSA: "...including SCSI, SSA, and Fibre Channel." but does NOT explain the acronym SSA.

The Index includes the acronym SSA, but only refers back to page 36, with no explanation of the acronym.

5.3.5 Loop address (page 132), and 5.4.2, first sentence, '"...the two upper bytes..."

"Upper bytes?" This is not a common computer term.

Exactly which bytes are upper? Bytes have byte offsets or byte addresses. Are upper bytes the bytes on the left side of the 24-bit port address? Or the right? Please be explicit.

This document is in need of an alphabetical explanation of acronyms and terms appendix.

5.7 Routing mechanisms (page 147), second sentence states: "The challenge is to route the traffic with a minimum of overhead, latency, and reliability..."

A minimum of reliability?

Mr. bruce lerner : it is a typo, that will be corrected. It should be SAS disks not SSA. Thanks for finding this out

NPV is not detailed explained (hints on page 296), could be explained in more detail.
For example: http://blog.scottlowe.org/2009/11/27/understanding-npiv-and-npv/

... NPIV is primarily a host-based solution, NPV is primarily a switch-based technology.
It is designed to reduce switch management and overhead in larger SAN deployments. Consider that every Fibre Channel switch in a fabric needs a different domain ID, and that the total number of domain IDs in a fabric is limited. In some case ...

On page 191, section 9.2.5 needs editing (abbreviated due to lack of space):

Although neither of these can be ... would be without them.

There are three items being discussed; "neither" refers to two. I believe the "as" is confusing. I think what the authors are trying to say is ...

Although none of these can be classed as security products or mechanisms, combining all their functionality can make the SAN more secure than it would be without them.

Thank you very much for making this book available. I really like it. A couple of small errors i found:

1.3.2, just below figure 1-4:
Stand-alone disks provide the following advantages: [...]
Stand-alone disks provide the following disadvantages:

should be: RAID 1 instead of Stand-alone

(above figure 1-9)
Up to one drive in Leach subarray might fail without loss of data.
Leach -> each
