Enterprise servers using SAS or SATA HDD?

[u0206397]

As above. Which type of HDD are used by those rack mounted HP/Dell/IBM servers in data centers?

Is SCSI still in use today or is obsolete?

 

[HelloSensation]

SAS for high-speed access in mission-critical deployments.

NL-SAS or SATA for not-so-critical stuff.

I refuse to answer such a dumb question. Go and google what SAS means.

Manners, please.

The forum is to help all users and be a source of knowledge.

He probably means those parallel attached type of SCSI. Is getting less. SAS is the way to go for Enterprise class.

NL-SAS is basically SATA drive with improve MTBF. Reason of NL-SAS vs SAS is for capacity. Usually NL-SAS is 2TB and above now a day.

Most enterprise server uses sas but some are starting to use ssd as well. Sas give higher performance than nl-sas which is sata

SCSI and FC (Fibre channel) are no longer use for Enterprise grade and yes, mainly replaced by NL SAS

It depends on the usage requirement and budget. I had encountered HP/IBM servers with SATA and SAS drives in DC.

Any enterprise that have SANs will definitely have to connect the SANs to the server via fibre channel.

What kind of HDDs they choose to put in their SANs is up to them. Can be SATA or NL-SAS or SAS. Most SANs accept all, but the SAN manufacturer will typically sell specially-supported ultra-high-speed HDDs with custom firmware for maximum performance.

And of course, they have the right to deny support for a SAN that isn't using their special HDDs.

Parallel SCSI is long obsolete..... long long long ago..... now is the serial version called SAS. Just like PATA vs SATA.

As for SAS or SATA, both are in use. There is NL-SAS as well.

Of course mechanical drives are still around. SSD is gaining popularity though.

Heard some servers room also slowly switch to SSDs... anyone can confirm

Depends on the purpose/usage of the server, it is already getting common to see servers with mixed SSD and HDD. So would not be surprised if random IO intensive servers go for an all SSD config

It depends on budget and purpose of server. Enterprise SSD is still very expensive. So, if its just mainly for data storage, hdd will do. SSD is used where high performance is required eg 10gb/s

Depends on management whether they agree with the value proposition in exchange for substantially increased cost.

define enterprise
have seen so called enterprise using different kinds of hdd
my desktop using ssd is more enterprise than a raid 5 sata enterprise server

Basically server lor.... so you know what is required for a server.

Enterprise is more than just performance. You can format your desktop ssd any time of the day. Power it down whatever... servers cant afford those downtime. Features like hot plugging, monitoring and remote management.

Raid 5 is not about performance. Its fault tolerant. You can reinstall your os and copy data from backup if your desktop ssd fails..... servers cant afford such down time. The failed drives must be replace and array rebuilt while everything is still running. Users not affected.

for me if a setup does not allow 24/7 ha then it is not enterprise enough
servers needs to be clustered
nobody does format anymore nowadays, all barebone and run vm
its all about templates, images, etc
again define enterprise

That's out of topic. SAN is about connectivity. Just like Ethernet switches. It also has basic version or director class. If your storage devices has enough ports for connectivity. You may not have SAN.

Hmm, so your desktop is setup as a HA cluster?
