HP MSA 2040 SAN scenario

Hello,
i have 5 servers hp dl380 g9 that is working with ms windows 2012 r2 and hyper-v
i plan to move all vhd files to hp msa 2040 san storage.
regarding my reading the scenario will be:
server 1 fiber channel 1 will connect to switch 1 on port 3
server 2 fiber channel 1 will connect to switch 1  on port 4
server 3 fiber channel 1 will connect to switch 1  on port 5
server 4 fiber channel 1 will connect to switch 1  on port 6
server 5 fiber channel 1 will connect to switch 1  on port 7
server 1 fiber channel 2 will connect to switch 2 on port 3  
server 2 fiber channel 2 will connect to switch 2 on port 4
server 3 fiber channel 2 will connect to switch 2 on port 5
server 4 fiber channel 2 will connect to switch 2 on port 6
server 5  fiber channel 2 will connect to switch 2 on port 7  
San Fiber 1 Connect To Switch 1 port 8 "Controller 1"
San Fiber 2 Connect To Switch 1 port 9 "Controller 1"
San Fiber 3 Connect To Switch 1 port 10 "Controller 1"
San Fiber 4 Connect To Switch 1 port 11 "Controller 1"
San Fiber 1 Connect To Switch 2 port 8 "Controller 2"
San Fiber 2 Connect To Switch 2 port 9 "Controller 2"
San Fiber 3 Connect To Switch 2 port 10 "Controller 2"
San Fiber 4 Connect To Switch 2port 11 "Controller 2"
in this case the acquirement hardware part number are:
Storagex1 : hp 2040 k2r79a
Server Cardx5: HPE SN1000q 16gb 2p FC HBA
Switchx2 :
HPE SN6000B 16Gb 48-port/48-port Active Power Pack+ Fibre Channel Switch
QR481B
Cable:x18 HPE OM3 2-fiber LC to LC multimode 1-meter fiber optic cable
transcevierx42:
HPE B-series 16Gb LW 25km FC SFP 1-pack Transceiver or
HPE B-series 16Gb SFP+ Short Wave Transceiver
is it right
thanks.

Base switch QK753B costs about £8000 and has 24 ports active, Q1H70A costs about half that with 8 ports active. Why pay for lots of ports you're not going to use? Why pay for 10Gb Ethernet when you're only using FC?

You don't want these :
HPE B-series 16Gb LW 25km FC SFP 1-pack Transceiver
They are longwave single mode for long distance.

You should ask HP if DAC cables are supported, that would save all the transceiver cost. You should be getting your reseller to check this for you anyway, decent receller will be cheaper than getting off the web.

Also you've spelt fibre channel wrong. the protocol is fibre channel, it runs over glass fiber (or twinax copper if you're lucky).

Hi Amin,
You have to make sure HA on all levels.
i.e. Two connections from all servers should go to each switch. (Switch 1 and 2).
Connectivity from (HP MSA) controller A data port to Switch 1 and Switch 2
Connectivity from (HP MSA) controller B data port to Switch 1 and Switch 2
Connect 1 cable from Controller A management port to your production/core switch.
Connect 1 cable from Controller B management port to your production/core switch.

hello,
i already do  that but i connect the storage dual channel for each controller to each switch.
in this case the storage will be connected at 32 gb for each switch
i want to confirm if the part number it will be work.
thanks

Hello,
sorry where i buyes 10gb ethernet ?
regarding the switch i have other san storage.
regarding my topology can i connect :
an Fiber 1 Connect To Switch 1 port 8 "Controller 1"
San Fiber 2 Connect To Switch 1 port 9 "Controller 1"
San Fiber 3 Connect To Switch 1 port 10 "Controller 1"
San Fiber 4 Connect To Switch 1 port 11 "Controller 1"
San Fiber 1 Connect To Switch 2 port 8 "Controller 2"
San Fiber 2 Connect To Switch 2 port 9 "Controller 2"
San Fiber 3 Connect To Switch 2 port 10 "Controller 2"
San Fiber 4 Connect To Switch 2port 11 "Controller 2"
so i can get 32gb speed to san  becuse there server connect:
server 1 fiber channel 1 will connect to switch 1 on port 3
server 2 fiber channel 1 will connect to switch 1  on port 4
server 3 fiber channel 1 will connect to switch 1  on port 5
server 4 fiber channel 1 will connect to switch 1  on port 6
server 5 fiber channel 1 will connect to switch 1  on port 7
server 1 fiber channel 2 will connect to switch 2 on port 3  
server 2 fiber channel 2 will connect to switch 2 on port 4
server 3 fiber channel 2 will connect to switch 2 on port 5
server 4 fiber channel 2 will connect to switch 2 on port 6
server 5  fiber channel 2 will connect to switch 2 on port 7  
regarding the transceiver i will use:
HPE B-series 16Gb SFP+ Short Wave Transceiver
thanks.

regarding documentation it's fc switch not fc ethernet switch
https://h20195.www2.hpe.com/v2/GetPDF.aspx/c04111492.pdf
and as i see i can use :
SN6000B 16Gb 48/24 FC Switch QK753B x 2
HPE B-series 16Gb SFP+ Short Wave Transceiver QK724A x 48 for switch side
HPE B-series 16Gb SFP+ Short Wave Transceiver QK724A x 10 for server side
HPE B-series 16Gb SFP+ Short Wave Transceiver QK724A x 8 for san side
HP E Premier Flex LC/LC Multi -mode OM4 2 fiber 1m Cable x48
in this case i will connect the storage
 controller 1  (A1.2) -dual channel- to switch 1
 controller 1  (b1.2) -dual channel- to switch 1
 controller 2  (A1.2) -dual channel- to switch 2
 controller 2  (b1.2) -dual channel- to switch 2
right ?
thanks.

OK, not Ethernet (the 10GB is for DWDM) but still you don't need all those ports, the other switch is half the price.

i want this part number: QK753B that have 24 port active .... to get a hight bandwith for it.
becuse the san trafic will be 128gb and each server will be 32gb
the total will be
128+32*5=288gb
the summery will be:
erver 1 fiber channel 1 will connect to switch 1
server 2 fiber channel 1 will connect to switch 1  
server 3 fiber channel 1 will connect to switch 1  
server 4 fiber channel 1 will connect to switch 1  
server 5 fiber channel 1 will connect to switch 1
server 1 fiber channel 2 will connect to switch 2  
server 2 fiber channel 2 will connect to switch 2
server 3 fiber channel 2 will connect to switch 2
server 4 fiber channel 2 will connect to switch 2
server 5  fiber channel 2 will connect to switch 2  
 controller 1  (A1.2) -dual channel- to switch 1
 controller 1  (b1.2) -dual channel- to switch 1
 controller 2  (A1.2) -dual channel- to switch 2
 controller 2  (b1.2) -dual channel- to switch 2

needs:

>the san trafic will be 128gb

Not with 12 x 7.2RPM disks it won't, you would be very lucky to get 200 MB per disk sequential throughput from each and you won't get anywhere near that with random I/O. You're building a multi-lane highway to put half a dozen bicycles on.

andyalderCommented:
As well as dropping the spec of the SAN switches to the one I suggested earlier I would also drop the spec of the storage box to an MSA 1040, all that money you will save can be spent on more (and faster) disks. You really do need to get a reseller's pre-sales consultant involved. You probably have too many servers (or very very much too few IOPS) in the mix too.  You have processing power and bandwidth for a couple of hundred VMs but only IOPS for 10 in the current spec. If you're lucky the reseller will even buy you lunch as well as saving you several thousand bucks.

hello,
i dont understand what to you mean with 10 iops
regarding my confugration that data storage will connect to two switch with 64gb  each switch
and 32 gb each server each switch that mean the each server will connect 32gb with the san storage.
thats right ?
thanks.

andyalderCommented:
How fast can you copy a 10GB file from one folder to another on your PC (assuming it doesn't have a SSD in it)? Try now if you don't know. Multiply that by 12 and that's about how fast your SAN will be. It doesn't have 64 Gb throughput just because the interface speed is 32Gb.

so could please suggest how i should connect it ?

Just follow the "Two servers/two switches" drawing on page 35 of https://support.hpe.com/hpsc/doc/public/display?docId=c03792322 ,additional servers connect to the switches same as the first two.

Te back-end SAS cabling is on page 21 for the additional disk enclosures you'll need if you want to get any reasonable speed out of it.

hello,
what happen if i connect all controller ports sfb to switch 1 and controller b ports sfb to switch 2
i will get more bandwidth ?
thanks.

You seen to be obsessed with bandwidth without a care for IOPS.

Amin El-ZeinAuthor Commented:
where is my problem with  iops ? in server or switch or san ?

andyalderCommented:
Use 60-80 IOPS per disk as Duncan Meyers suggests in https://www.experts-exchange.com/questions/28353924/IOPS-latency-disk-access-time-for-HP-2TB-6G-SAS-7-2K-LFF-DP-MDL-AW555A.html. That gives you about 1000 IOPS for your storage, assuming 32K blocks on average that's 32 million bytes per second so you'll need a whopping 320 Mb of bandwidth.

in this case the solution is:
erver 1 fiber channel 1 will connect to switch 1
server 2 fiber channel 1 will connect to switch 1  
server 3 fiber channel 1 will connect to switch 1  
server 4 fiber channel 1 will connect to switch 1  
server 5 fiber channel 1 will connect to switch 1
server 1 fiber channel 2 will connect to switch 2  
server 2 fiber channel 2 will connect to switch 2
server 3 fiber channel 2 will connect to switch 2
server 4 fiber channel 2 will connect to switch 2
server 5  fiber channel 2 will connect to switch 2  
 controller 1  (1.) -dual channel- to switch 1
 controller 2  (2.) -dual channel- to switch 2

it will be fine right ?

From your initial question:
>i plan to move all vhd files to hp msa 2040 san storage.

What's are they on now? how many disks in the current solution? What rotational speed are they?

Amin El-ZeinAuthor Commented:
it's on sas 12g on servers
working on raid 10 x12
and the storage will have sas 12g , raid 10x12 too.
thanks.

Just cable it up as per that page in the manual I linked earlier.

I don't believe you really do not know what "rotational" means, I think you are taking the mickey.
