Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

I have a hp z800 and want to setup esxi 5.5 on it as a home lab but i am not sure what kind of disks to purchase and how to configure the built in intel raid (is this considered as software raid? If so i dont think ESXI supports software raid and I may need to purchase a physical LSI - pcie raid hardware card)  so that vmware will be able to see my hard drives as a datastore. I will also be running esxi off of a usb thumb drive.

I also believe 2TB drive is the largest siz drives i would get (i know some of it gets lost but how many 2 TB drives would i be able to use and what would be the expected available size after setting them up in raid and what it the best raid configuration to put it into Raid 5, 10?

Thank You in advance for your time!

Active Protection takes the fight to cryptojacking

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

Currently I have a 2012R2 storage spaces pool of  4 x 1TB HDDs in a two-way mirror, no tier. If I need more space, can I just add one more, yes just one more 1TB HDD and hope it will increase half TB of free space?

Hi,

On one of the Windows 10 PC in our office, C: drive was about 95% full.

We noticed that Google Drive has a folder in it.

I moved the Google Drive folder to the D Drive on this PC.

What do I need to do now?

How can I tell the online version of Google Drive where the local one is now?
 
Thanks,
Robbie

Hi!

I wish you could help me with the following question about SQL Server and a performance problem I have:


Old Server:

I have a closing and opening process on my system that takes about 11 minutes.  


My storage is:
3Par 7200.
Raid5 15K SAS ( 35 disks)
Block Size: 128KB

IOPS  can deliver as maximum for Reading and Writing in a native way:  IOPS 9950


 3par-7200.png

The server has the version of SQL Server 2008 R2 Enterprise Windows with 2008 R2 Enterprise. It has 2 Processors with 16 Cores but the SQL Service only recognizes 16 cores.  

I haven't been able to capture the IO statistics or specific time in the processes because this process has many cursors and makes the SQL Server crash. Neither have I been able to capture the execution plan by the cursors that the process has.

New Server:


The same process takes 8 minutes but writing IOPS rise from 800 to 2000. Reading IOPS decrease from 1000 to 400.

 3Par 8200 with the following features:

Raid5 SAS of 10K ( 10 disks)   IOPS 2568Max. For CPG FC_Raid5_SinAO
400 Gb SSD disk arrays ( 8 disks)  IOPS 100239 Max For CPG_SSD_Raid5
Block Size: 32KB

IOPS can deliver as maximum for Reading and Writing in a native way: IOPS 2568
IOPS with AO 30,000 Max Reading ( The writing processes depend on the Native IOPS of the CPG used in this case FC_Raid5_10K )

Greetings,

I am trying to set up an OEM VMware server for in-house use with the following components:

ASUS Prime Z390-A motherboard socket 1151 motherboard
Intel Core i7-8700K CPU
32 GB RAM DDR4 2133 MHz

In addition, I am wanting to use an LSI MegaRAID SAS 9260-4i SATA RAID controller with SFF 8087 mini-SAS interface on the controller, and hook up a pair of SATA drives in RAID-1 configuration for the VMware datastore.  FYI I have 6 VMware servers running in house already with the same controller, but with different motherboards.

When I power the system on, the ASUS motherboard comes up OK and I can get into the mboard BIOS fine.  But the LSI card never shows up anywhere.  Normally the LSI card shows up in the overall boot process with a display of e.g. its BIOS version, firmware version, etc.   It will say something like "HIt Ctrl-H to enter controller BIOS".    But it is as if the card is not even in the system.  I tried 2 different cards and neither shows any sign of being in the system.  The system boots into the ASUS BIOS and stays there.  It does not show the card as a bootable device.  I tried booting with the controller without any drives attached, then with a SATA drive attached to the controller.  Same result each time - the controller is essentially invisible to the rest of the system.

Any thoughts on what to do to get the motherboard to recognize the LSI card?  Or is this mboard too new - or maybe too fast - for the LSI?

Thanks in advance for …

I using Vcenter 5.5 connected three esxi host found one of esxi host can't connect to NAS storage

1. Add this NAS from esxi host > Storage Adapters >   Dynamic Discovery > iSCSI  server location
2. Add this NAS from esxi host > Storage Adapters >   Static Discovery > Discovered or manually iSCSI target

Problems:
1. Can not find those NAS from Ethernet Adapter
2. Can not find NAS from > Storage > Scan All and Refresh

The other two esxi host can connect to this NAS with same network switch.

I have 4 x 1TB Storage Spaces (2-way mirror, hot-swappable, no more spare swappable slot available) on a 2012R2 server. One of the hard drives appears to be failed in Smart alert even the drive still shows healthy on the OS. After already identified the potentially failed drive and felt ready to replace the failed drive, I became so confused about how to while reading through articles on the net. Some said I need to insert a new drive in before doing anything but I don't have any empty slot available. Can you shed some light on this please?

Also, I understand in Win10, there is a "Prepare for removal"/"Ready to remove" option to remove a drive from an SS without the need of issuing any PS commands. Thus, I'm wondering if I can just select "Remove" the failed physical drive from Storage Pools/Physical Disks list on GUI and then physically replace the failed with a good one. Then add that new good drive back to the pool. Will that work?

Hoping to get some expert advise here. We're trying to implement best practise network redundancy and throughput for our storage environment with vmware ESXi and Synology NAS DS1618+ with 4 NICs.

We've created a LUN on the NAS and want to use that as a datastore for two ESXi hosts.

For iSCSI traffic, only one subnet will be used, and only for iSCSI. Each host will have one vswitch dedicated for iSCSI with two vmkernel ports (and associated vmnics), each with their own IP address in that subnet with correct multipath and port binding enabled. Each host will be connected to two separate switches.

The confusion comes with how to connect the 4 NICs on the NAS. I want one NIC for management, and not sure how to best utilise the other 3 ports. It's only used for iSCSI really. I also want to have redundancy on the NAS, so want also to connect that to two switches. Not sure how many targets I create, what NICs to use and how (or should) I bind them in DSM). Can I bind them and then do link aggregation on the cisco switches?

Any help is greatly appreciated.

Photoshop.  I have a .psd file that I saved to a USB drive and the last time that I worked on it I hit "save" and powered off my computer before the "save" actually occurred and the rather large labor intensive file is now corrupt and I can't open it.  I have attached it to this question.  Any help would be greatly appreciated!  I had to compress it as it was over the 50mb limit.

Hello everybody,

I am trying to migrate the cifs shares from a VNX 5400 to UNITY 400 storage using the Data Mover Tool.

All went well untill on the Unity I am not able to see the Cifs shares I need to import.

So here it is what I have done untill now:


1. I have added The interfaces on the unity which will allow us to migrate and later to do the replications
2.On the VNX I have created a new interface for each cifs share and then attached it with this cmd line

server_cifs <vdm_name> -add
compname=<compname>,domain=<domainname>,interface=<nas_
migration_interface>,dns=<specific_prefix.domainname

3. Once this is done we will have 2 IP adresses on the cifs shares on the VNX
4 I have also executed those cmd lines on the vnx :

server_param server_2 -facility cifs -modify acl.extacl -value 28
server_param server_2 -facility cifs -modify acl.mappingErrorAction -value 11

5. On the Unity I have created the Connection link with the vnx

6. And finally when I am trying to create a new import session in order to start the migration , I am not having the CIFs I need to migrate.

Anyone has any ideas please?

Thank you very much,

Regards

Basic question around packet sniffer and applications - Can a sniffer pick up and read the content of a word document as an example. - Our storage (data at rest) is not encrypted
So if i use a good sniffer and can capture the data in-line, can I then in any way use a quality packet sniifer to  see the content of  say a word document being opened by a user?

I can't find information weather IBM storwize v3700 storage supports TRIMM/UNMAP. I have Win2012R2 Hyper-V cluster connected over SAS interface to the v3700, but space reclamation on clustered shared volume doesn't happen.
Trimming is by default enabled on Win2012 (i checked).

Thank you.

CEOs need to know what they should worry about
CEOs need to know what they should worry about

Nearly every week during the past few years has featured a headline about the latest data breach, malware attack, ransomware demand, or unrecoverable corporate data loss. Those stories are frequently followed by news that the CEOs at those companies were forced to resign.

We have several Dell PowerEdge R515's with PERC 700 controllers. Each has several sets of RAID 1 mirrored disks. I would like to know whether there's a procedure which will allow us idle/offline a mirrored pair, remove both of them from the chassis, and later re-insert them without incurring a rebuild. If so, then is it also possible to use a similar procedure to move the two drives to another server, import the foreign configuration and also to resume operations without a rebuild?

I bought a new desk top computer last week and already filled an entire disk and a half with mostly apps and programs. Is there a way to move these things to the other disk. When I try these is only an option to copy. I was able to copy the download shortcut to a second disk on my laptop and copy some of the main files like program files in disk C over to D but that didn't solve the problem because I couldn't erase them from C. Are there any programs to help with this?
