One suggestion and I'm talking Brocade here. Presumably Cisco have something similar but I'm not familiar with those. Are we using multiple switches here and are there ISLs between them? If so, an ISL can only go 10km and then you should have the Extended Fabric License. This allows you to

Re: DASD problem

Tommy, The RTD at 30km is quite small, and the benefit of write spoofing will be small. There is an option to turn on write spoofing with the FCP PPRC links on IBM storage, but you should check with them that it is a benefit at small distances on your model of storage at all write rates. Ron

Re: DASD problem

Tommy, That's a really big question. You're talking about a complete batch tuning exercise. The increased buffering is an old tuning hack, but with synchronous replication, the primary benefit is for sequential writes where you can achieve the Host/RIO overlap. It works equally well for the

The problem is not that the term "ASCII" is ambiguous; it isn't. The problem is that people don't understand what ASCII is and refer to things that aren't ASCII as "ASCII". Code pages like 437, 850 and ISO-8859-x aren't ASCII, and if IBM documentation refers to them as ACII then that is a

I know that it is possible to use DIV (Data In Virtual) to "map" an LDS into an address space. And then use "windowing services" to move the "window" around within the LDS. What I would really like to do is have an LDS. And, somehow, have an API which would take this LDS and create a data space

Re: DASD problem

A switch can relieve the limitation, because it's actually limitation of SFP (electro-optical converter). You can replace SFP in the switch so your new CPC is connected to 16 or even 32 Gbps SFP in a switch, but your old CU is still connected to a 4 Gbps SFP, which can slow down to 1 Gbps. And
