Hi,

I want to move page file from System drive partition to a different logical drive partition, I want to double memory in my Exchange Server, and there is no enough space.
Is it all OK if I move it there in Exchange perspective?

Thank you for your time.
 
If you can avoid it, don't put it on a spindle that also has your transaction logs on it. The partition doesn't matter as much as whether it's writing to the same physical disk as your transaction logs.

If you tell us how you've allotted your disks, we could give you better advice. Something like this:

RAID1 with C: and D:
RAID5 with E: and F: and G:
RAID1 with H:

Each line is its own set of spindles, so if you put your page file on E: and your transaction logs are on G:, that's not very good. But if you've put all your logs on H: and you just want to move your logs from C: to D:, that's probably fine.

I'm using RAID 1 for Logs, and RAID 5 for the rest OS, and databases, around 50GB in total for now. I have around 1GB log traffic per day.

I have page file on C: drive, and assuming page file size Memory + 10MB, I'll run out of space. In the beginning, it was designed with small partition size, so I have to live with it for some time.

We are going to implement CCR in few months time, and I would use this thread to if you agree to discuss about my optimal needs.

 
I'd move the databases to something other than RAID 5 for performance.

I'd also put the swap on it's own volume. Both for space and for performance.

Plan for performance, and capacity takes care of itself. Plan for capacity, and suffer poor performance.
 
How big is C and how much space is on it? What size is the pagefile? How much RAM?
 
C drive is 30GB , and I want to double memory from 8 to 16GB.

In addition, based in you experience, I would like to find out what are optimal resources that we would need for CCR.
We'll have 250-300 users, 1GB of mailboxes ,and 2-3GB max logs per day. I know, we have to put Mailbox role separetely, but can we put HT, and CAS role in single machine (per cluster), and does it need to be strong one?
 
You'll want to carefully design the storage so as not to impact performance. CCR requires two dedicated servers with dedicated storage. You'll need to take things into consideration such as Blackerry, any archiving, etc.

As for CAS/HT, you can put them on a dedicated machine. In an environment your size, there shouldn't be a problem with putting those roles on a small server. You could use two servers and load balance them to provide redundancy.

I am surprised, though, that you think you'll need more than 8 GB of RAM for only 300 users. What's driving that upgrade?

We don't have any Blackberry, but around 50 mobiles with Activesync. For archiving, I downloaded trial of GFI to see if it fits our needs, means how users access it. I don't know for any other good product.

For CAS/HT, honestly I didn't read anything, I wanted to know whether each Mailbox Role Server uses its partner in normal circumstances, or CAS/HT work both in the same time sharing the load.
I want to put it top priority, because this weekend I was trying to do some restore in a new server, and I couldn't catalog the tape. Everything is new, tape is working. I still don't know what is going on. I'm going to write to HP, and to see if they have any idea, any frimware, driver or..

I have a new server staying in standby, and I wanted to use its memory, since it is not doing anything.
 
I'm thinking for 2 good servers, I can play with details. Do you have any recommendation?
 
300 users with 1GB mailboxes means 300GB of stores which is 2 or 3 stores (preferably 3!).

Not sure on your user weights but let's assume heavy. You'll need RAID1 for OS and apps. RAID1 or RAID10 for logs (pref each store) and RAID10 for stores (preferably each store).

So ideally you'd need 20 disks and at a minimum you'd need 8.

"2 good servers" is all well and good but you need to be thinking about disks. I'd be looking at 15k 2.5 inch SAS disks for the stores and 10k 2.5 inch SAS disks for the logs and have 1 RAID1 array per database.

Yes, you still need a second server but you also need a third server to do your hub transport / client access server which would also act as your witness.
 
That felt like a really long post and actually wasn't. For 300 people I'd certainly be looking at an offboard DAS and an offsite CCR (because it is a DR box then too). If you keep them both next to each other I'd be looking at shared storage solutions such as NetApp and use their backup solutions.

Speaking of which, you'll need a good backup solution.
 
Idea is to use both next to each other, and we would like to have redundancy in everything if possible. I guess, in that case we can buy two good Servers to handle Databases, and two smaller for HT/CAS.
As a backup solution we are buying Symantec Backup Exec 11d. I've read it does online backup. I hope it is good product.

Is it enough to have four servers for these three roles, and can we reach full redundancy with that (apart of witness file). And I have to install to install AV for Exchange in both HT if I'm not wrong.

Sorry for bothering to much with details, but it is very much different when you explain your situation to experienced people than reading in books which show information of general use.
 
For 300 users, that is a lot of hardware!

Possibly:

1 MB with BE 11D as a CCR live node.
1 MB with BE 11D and CAS/HT and AV and as CCR passive node.
1 CAS/HT with AV as witness.

Which would eliminate one server and Exchange licence. You could use DAS and go for some kind of Dell PowerVault or similar on each MB box.

Lots of ways to do this including just going for a single box solution - I've done that before.
 
Don't tell me I need an Exchange license for every server with whatever role. I know for Windows license, but having Exchange Enterprise license in each server seems to me to much.

I've watched a video presentation of BE 11D, and they say that it does online backup (a sort of LCR if I can say). Does it work fine, if I backup Exchange in a Storage Server. I want to avoid daily backup in tape drives (this is always if CCR comes to expensive in the end).
 
Yes, Exchange needs to be licensed per server hence trying to minimise the boxes required for you!

BE11D does a great job. Daily backup to tape is belt and braces and works. Back up to disk is always an option if it is off box.
 
Zelandakh,

Thank you very much for all this information. You truly put me in the right track. Now it's our time to decide what to do. But in thing is for sure, not completely dependent on backup tapes.
 
You are the guy doing the work.
Your Boss / firm are paying so you need to think about that.
TT can help clarify your thoughts (like the above stuff).

We can't tell you what to do as we don't know your organisation.

Hope we've helped.
