Is IBM's File Server I/O Processor (FSIOP) really the file server entree we've

been waiting for? IBM's been getting a lot of flack about FSIOP. Here are some

of the complaints:

o It's just a 486 "bag" on the side of the AS/400.

o It runs only on OS/2 LAN Server 2 and has no management graphical user

interface (GUI).

o It uses expensive AS/400 DASD for warehousing client data and programs.

o It has no hardware upgrade path. (No socket for faster future

microprocessors.)

o Etc.

Gosh! Who would buy one of these things? Well, as an IS director of a small to

medium-sized AS/400 shop, I might! Here's why:

The real cost of implementing a LAN is not only the cost of the hardware. It's

the cost of maintaining the LAN resource itself. Configuring new profiles,

making connections, integrating services, backing up files, and plain old

problem solving are all tasks that consume tremendous personnel resources. If I

bring in a new file server, suddenly I've got two sets of problems: my current

AS/400 SYSOP tasks and my new server network administrator tasks. What am I to

do? Go out and hire another person?

And what about my users? When they want access to a new set of servicesùor if

they're having problems with a current service--who will they talk to? The

AS/400 SYSOP or the network administrator? Or both?

That's the real beauty of IBM's FSIOP solution. IBM's FSIOP integrates the

functions of a SYSOP with the functions of a server network administrator. With

the FSIOP, my present SYSOP can manage these duties right now, from the same

seats where she's been sitting all along. Changes in configuration, user

profiles, and service access are managed as an integrated part of the OS/400

administration. OS/2 LAN Server maintenance is available from any green screen,

so my SYSOP doesn't have to handle two screens on her crowded little desk.

Backup and recovery flows quickly and easily into her preestablished, time-

proven routines. And when users have problems, they know immediately where to

go for help. There's no finger-pointing, no long conferences, and no crossed

communication.

Don't get me wrong: hardware costs and performance are important

considerations. But in my 25 years of experience with hardware, I know there's

always somebody with a faster, cheaper hunk of iron who's ready to sell me a

piece of the action. I don't need more hardware right now, thank you. I need

better network management tools. And so far, there's only one vendor out there

who's selling me a piece of that solution. Thanks IBM! Thanks for listening!

This is a good start!

Tom...I'm glad to see they're letting you out of the Home to write, but get a

grip. In its current configuration, the FSIOP is, well, let me put this in

technical terminology: a boondoggle. Few "medium-sized" shops would choose to

run a 486/66-based version of LAN Server. The 486/66 is not a worthy chip; its

performance under network loads is underwhelming at best.

Also, since most folks now use PCs rather than dumb terminals (sorry, mentally

challenged workstations), there's no need for two screens on your SYSOP's

"crowded little desk." (Hint...get a bigger desk!)

The key issues on the FSIOP are that it is a bag on the side of the AS/400,

that it does use high-priced IBM memory, and that it doesn't use a ZIF socket

for the CPU. Why should people limit themselves (and their users) to a closed-

end solution like LAN Server? The world is full of bright, young faces who are

fully versed in NetWare and NT.

There's much more support for those products (due to their large constituency)

than for LAN Server. This support makes getting help, fixes, and tips on

network management much easier. Since you're going to have to train your SYSOP

on some network operating system, why not go with one that has a broad support

and user base?

You say you need better network management tools? Sheesh, with LAN Server? Now

that's a laugh! Habla NetWare? Parlez-vous NT? If you're determined, however,

to remain closed-minded about the future of LANs in an AS/400 environment, go

with the LAN Server version of the FSIOP.

It seems that workstations aren't the only things being mentally challenged

these days.

I applaud IBM for creating a product that allows the AS/400 to act as a PC file

server. The FSIOP is long overdue and an important step in the future success

of the AS/400. When you combine one of the AS/400 server models with an FSIOP

and V3R1's Integrated File System, you've got a box that can seriously compete

with other PC file servers on the market.

I had the opportunity to try out this configuration at the recent COMMON Expo,

and I was impressed. Anyone who's suffered with the slow speed of shared

folders would have to agree it's a big improvement. With an FSIOP, you can

store PC files on your AS/400 with access speeds similar to the speed of

storing them on your local hard drive. It also has some other nice features,

like the way the system automatically keeps AS/400 profiles in sync with your

LAN profiles, and the fact that you can keep your AS/400 and LAN data backed up

with a single save/restore strategy.

Sure the FSIOP has some faults. It could stand to have a faster processor,

support for user upgradable memory, and more choices of network operating

systems. But let's face it: this product is only in its infancy. I believe IBM

will address these and other concerns in the future. IBM has already made a

statement of direction to support Novell NetWare. I would expect to see other

improvements like this over the next few years.

Obviously, the FSIOP is not for everyone, but for those who want a turnkey, no-

hassle solution, it's probably a good fit. I'm anxious to see how this product

evolves over time. I think it has the potential to become an important

technology in the AS/400 industry as it matures in the years ahead.

Tom's introductory question is "FSIOP--Is it the solution?" I don't mean to put

words in his mouth, but I suspect he really means, FSIOP--Is it a solution? I

don't think he is arguing that everyone who has an AS/400 should rush out and

buy an FSIOP. I do think that, in certain very specific situations, the FSIOP

does have a place.

The FSIOP seems to be fit for small shops that have only an AS/400 and don't

have a LAN in place already. The benefits include the ability to call a single

vendor (IBM) if you have problems with the hardware or software. Tom is right

that, for a small shop, the consistency of maintaining the LAN environment in

conjunction with the AS/400 environment can be helpful. If you are in a

situation where you are the data processing manager, computer operator,

programmer, and data entry person, and now your management says you need to

implement a LAN, the FSIOP may be just what you're looking for.

For larger environments and those sites that already have a LAN, it is

difficult to ignore the issues that Tom raised as concerns about the FSIOP.

Those points directly relate to the value of the FSIOP. The value is the

relationship between the cost of the hardware and software (remember, IBM is

supplying this and doesn't make anything inexpensive) and the benefit you gain

from that package.

If there is no easy and inexpensive upgrade path, that reduces the value. If

you have to train someone used to graphical LAN administration tools to use an

inefficient text interface, that reduces the value. If the FSIOP doesn't run

the Network Operation Systems (NOSs) you're running already, all of these

things reduce the value.

The FSIOP has a place in certain shops in certain situations, but it clearly is

not the solution.

--Jim Hoopes

Kudos to IBM for an innovative idea that could prove to be a major contributor

to the continued success of the AS/400. What a great ideaùto consolidate,

integrate, and simplify the myriad of disparate hardware and software

components involved with computer networks.

I think the solution the FSIOP provides is the important thing to look at, not

how the engineers decided to implement it. Look at the benefits the FSIOP

provides:

o It integrates network management, so it's possible for the AS/400

adminstrator to manage the resources of both the AS/400 and the LAN from any

AS/400 terminal or attached PC.

o It adds the AS/400's reliability factor to a LAN.

o Your AS/400 and LAN save/restore strategy can be combined into one integrated

procedure that takes place at one physical locationùthe AS/400.

Hey, this solution sounds pretty good! I'm not saying that you should go out

and replace an existing PC server with an FSIOP. After all, you wouldn't want

to replace your PC LAN administrator; your company might have to pay higher

unemployment taxes.

Sure, there are more powerful chips than the current FSIOP 486/66, but is the

performance of a server simply a factor of CPU power? Isn't file I/O a

significant factor? I'd guess that a 486/66 CPU is plenty of CPU power for

typical network loads. Also, don't forget, you can now install up to four

FSIOPs on a single AS/400. Kris, I wouldn't get too hung up on the CPU.

In a world where computer networks are spreading like wildfire, I think it

makes a lot of sense to give the AS/400 a chance not only to participate, but

to offer a superior solution.
