In previous firmware released, DELL PERCs adapter will refuse to operate with non-DELL disks. This changed with later firmware released. So, first thing is to be 100% sure that no other update exists for the PERC card. After you are sure that the card is updated, try to power-cycle the server and press CTRL + R to enter in the RAID BIOS screen. Here you ...

To verify a partition is aligned, query it using /usr/bin/blockdev as shown below. If a '0' is returned, the partition is aligned: blockdev --getalignoff /dev/<partition> Source: https://wiki.archlinux.org/index.php/Partitioning#Partition_alignment

The accepted answer works for vSphere 6 as well, and it works for both local and remote SSD drives either with JBOD or RAID configuration. The additional commands not mentioned in the answer are: # esxcli storage core claimrule load # esxcli storage core claimrule run # esxcli storage core claiming reclaim -d <naa.ID> Then you can test if you were ...

AWS supports RDS Instances provisioned with SSD's either manually via the AWS Console or using a CloudFormation template to assign SSD storage to your RDS Instance when you spin it up, with a few caveats: As of this writing, if you specify any DBSecurityGroups in your CloudFormation template, the StorageType attribute will be ignored You CAN specify both a ...

MLC SSD really need a fast private DRAM cache for delivering high IOPS values. While your controller has its own cache and it is enabled, your disk's private DRAM cache is disabled. This is a safety measure, as enabling that unprotected (from power losses) cache can put your data at risk. Sometime it is safe to reenable it (eg: your disks has power loss ...

There are a few issues here. You don't have any controller write cache or a battery-backed or flash-capacitor. The HP Smart Array P410 controller is limited in IOPS capacity. It's not a good match for SSDs. Using SATA drives on a Smart Array P410 causes the interface speed to downshift to 3.0Gbps instead of 6.0Gbps. Please try with RAID 1+0. RAID5 is not ...

ESXi and HyperV would both allow you to utilize the spindle drives for a "D" data drive with ease - just store a 2nd virtual disk on those drives, presented to each VM. Server 2012 R2 also offers Storage Spaces, with which you could configure both SSDs and 7.2K drives with "tiering", which would allow for "hot" data to be auto-tiered to the SSDs regardless ...

This wouldn't be a terrible idea, assuming you get SSDs that are rated for the type of use you need them for. I'd assume that not requiring much "horsepower" means both CPU and disk I/O, so there'd be no need to splurge on SLC drives. Are you planning to buy a server from a vendor, or build one yourself? If you don't buy vendor-certified SSDs (or you build ...

FYI the same server type can have different backplanes for a server model, in your case you have a SCSI Backplane as the guys have already told you. Unfortunate mistake. little point buying the adapters as they won't fit in your hotswap environment, just buy the SCSI drives those SSDs will come in handy later..

There are products for this but they are converters not adapters so are higher priced. One example is: ARS-2320S Ultra320 SCSI-to-SATA II Hard Disk Drive non Hot SWAP As mentioned by others your server and old drive use the SCA 80 pin connector which pre-dates SATA/SAS and was used to provide hotplug support for SCSI drives.

Oh my... What the heck are you trying to do?!? This is a bit of a square-peg in a round-hole issue. SCSI is not SATA or SAS. Your Dell server is a PowerEdge 1850, which featured parallel SCSI (Ultra-320 SCSI) drives. These disks connected to an 80-pin SCA connector on the drive cage backplane. SATA and Serial-Attached-SCSI (SAS) superseded the old ...

The Mushkin spec page says it is SandForce powered. The SSD life left if that is indeed the attribute has no direct relation to the other values. There may or may not be another problem. The thing is that the SSD life left only counts the number of writes done to the NAND and compares it to the specified limit for that NAND, so if the NAND is specified for ...

You're not one for the scientific method, are you? Different operating systems. Different platform (server versus workstation). Different CPU architecture. Unsupported SSD on the RAID controller. Raw SATA versus a disk connected to a RAID controller backplane. The assumption that a RAID controller is supposed to be "faster". Misconfigured settings on the ...

In case anyone is still looking, like I was. You actually want one of these: http://www.amazon.com/Adapter-Bracket-9W8C4-F238F-Hhard/dp/B00DCBFF8Q/ref=sr_1_1?ie=UTF8&qid=1428706444&sr=8-1 It's a Dell adapter bracket model# 9W8C4. It screws into the sleds and allows them to accommodate the 2.5" drives. Benefits are that there are no electronics to ...
