UPDATE: This blog entry discusses 2.5 inch SAS drives, NOT 3.5″. Yes, 300GB 3.5″ SAS disks are available, but in this entry we are solely concerned with 2.5″ drives compatible with Sun Fire Galaxy Servers and other 2.5″ based servers. Please don’t mail me telling me that 300GB SAS Drives exist, look close, they are all 3.5″ drives which I do not discuss here.
In my last post regarding the new Intel based Sun Fire systems (X4150 andX4450) I said: “With stock disks coming in 73GB or 146GB, and the ability to purchase larger drives on the open market.” Now, I swear that I’ve seen 300GB 2.5″ SAS disks on the market but a quick search while writing the blog entry and I couldn’t find them. Rather than lead my storage savvy readers wrong I thought I’d do some research on the subject and share my findings.
So, lets go through the disk manufacturers. First up, the venerable Seagate. Their SAS lines divided into families: Savvio for 2.5″ enterprise drives, Cheetah for 3.5″ enterprise drives, and Barracuda ES for enterprise class sub-10K RPM drives. So, Savvio breaks down into 2 sub-classes:
- Savvio 15K: 15K RPM SAS 3.0GB
- 36GB
- 73GB
- Savvio 10K.2: 10K RPM SAS 3.0GB
- 73GB
- 146GB
Ok, no 200GB+ drives from Seagate (yet).
Next up, Hitachi the owner of what was IBM’s HDD business. Here we have:
- Hitachi UltraStor:
- Ultrastar C10K147: 10K RPM 3.0GB SAS 73GB
- Ultrastar C10K147: 10K RPM 3.0GB SAS 147GB
Again, nothing greater than 200GB from Hitachi. Moving on…
Western Digital is focused on the desktop space. The best they can do is that popular enthuast drive WD Raptor 150GB 10K RPM SATA. This drive is awesome, btw, its the only drive I’ve ever seen Windows (bleh) ever be even moderately performant on. Someone correct me if I’m wrong, but based on WD’s website they don’t offer any SAS, SCSI or FC disks anymore. So no help from WD.
Maxtor, another consumer/desktop focused drive maker. They aren’t any help because, if you haven’t already heard, they were acquired by Seagate.
Next up, Samsung. I don’t see these much, but they are a HDD manufacturer. Their “Enterprise Class” drives are SATA only, no SAS at all. So, no help there. They do, however, have an interesting new offering to check out: Hybrid HDD – FlashON. These are slow 5,400 and 7,200 RPM 1.5Gb SATA drives that incorporate Flash as a write buffer allowing faster resume, boot, and allow power savings by powering down the drive untill the write buffer needs flushing. Interesting idea but the capacities are really small, the largest drive is 160GB. Worth a look though.
And that brings us to the final manufacturer, Fujitsu. They have 3 drives…
- Fujitsu Enterprise Class Drives:
- MBC2073: 2.5-Inch, 15K, SAS available in 36GB and 73GB.
- MBB2147: 2.5-Inch, 10K, SAS available in 73GB and 147GB.
- MAY2073: 2.5-Inch, 10K, SAS, available in 36GB and 73GB.
And… thats it! So we can therefore draw the following conclusions today:
- There are only 3 common sizes found on the market, ~36GB, ~72GB, and ~146GB.
- If you want 15K RPM SAS the biggest disk you can buy is 73GB
- If you want the largest capacity 2.5″ SAS disk 146GB at 10K RPM is the ceiling.
Now… with that understood, some random pricing.
- Fujitsu MAY2073RC 73GB 10,000 RPM 16MB Cache Serial Attached SCSI (SAS) Hard Drive – Retail: $260
- Fujitsu MBB2147RC 147GB, 10K RPM. SAS: $600
- SEAGATE Savvio 10K.2 ST9146802SS 146GB SAS 10,000 RPM 16MB Hard Drive Bulk: $450
- SEAGATE Savvio 15K ST973451SS 73GB SAS 15,000 RPM 16MB Hard Drive Bulk: $475
- SEAGATE Savvio 10K.2 ST973402SS 146GB SAS 10,000 RPM 16MB Hard Drive Bulk: $270
- … can’t even find pricing around for Hitachi drives.
And so, there we go. A whirlwind tour of the 2.5″ SAS market today. Thus, we find, my statement that “larger drives are available on the open market” was a lie, because they aren’t. But, they will be in the future I’m sure. So the fault isn’t with Sun but rather with my own research, but I’m glad in a sense that it forced me to go digging a bit.
Hitachi UltraStar 15K300, 300GB, 3.5″, 15Krpm, price 915 euros (model HUS153030VLS300)
Seagate Cheetah 15K.5, 300GB, 3.5″, 15Krpm, price 685 euros (model ST3300655SS)
Gahh, I misread your post… both are 3.5″ drives
Maybe they’re referring to SATA disks, though it does look like they’re implying SAS up there. SATA disks plug into SAS controllers just fine though.
As I understand it, a SATA version of the X4150 (6 internal SATA drives) will be released in the next two to three months. Assuming Sun get the pricing competitive (which is sometimes a big assumption), that’s good news for anyone that’s price-sensitive when it comes to paying for storage. On a price/GB basis, SATA is ten times cheaper than SAS.
Ben:
Seagate does have 300GB SAS drives. I believe this is the model we’re using:
http://www.seagate.com/ww/v/index.jsp?vgnextoid=f0214e92987c0110VgnVCM100000f5ee0a0aRCRD&locale=en-US
Super, super-expensive, though…
Paul: Remember, we’re talking about 2.5″ SAS. The drive you pointed to is a 300GB 3.5″ SAS Drive (Cheetah, as noted in the entry above)
I think I may have had something to do with this post so here is a bit of an explanation from my side. I criticized Sun for their lack of choice when it comes to built in storage on their servers in your previous post. You are correct that mainstream systems don’t see SAS drives larger than 146GB in the 2.5″ factor. However, my company has bought a few 2950′s from Dell and Dell is literally full of choices. You can buy it with eight 2.5″ drives or six 3.5″ drives, both SAS and SATA – be it 8x73GB 15k 2.5″ SAS drives, 6x146GB 15k 3.5″ SAS drives or 6x500GB 7.2k SATA drives.
This is what I consider to be choice and it has enabled us to buy a system that better fits the purpose it is bought for. This isn’t really a fair comparison to the X4150 which is a 1U system compared to Dell’s 2U size for the 2950 so I should cut Sun some slack. However, if you want to buy a V240 (for example) with decent internal storage then you are simply out of luck. I gather that Sun does this for several reasons such as purchasing larger quantities of fewer components to keep prices down but also to force customers to buy external storage if they need more space. This in turn a system like the V240 into a rather expensive system that is hard to justify to the bean counters. So all in all we don’t buy a lot from Sun because of the lack of choice (that even applies to areas other than just the storage part) and because of price.
I would love to see more Sun hardware around our shop. I do agree that the quality and finish is very high but fact of the matter is that our Dell servers don’t break down either.
Dell BIOS, MegaRAID, and LOM suck assssssssssssssssssssssss. 3.5″ drives are history, besides, they’d block too much airflow.
The BIOS on real Dell machines (the PowerEdges) is actually pretty solid. Any RAID controller after the PERC3/DC was good, but the latest generation, the PERC 5s based around the MegaRAID SAS hbas, are awesome. If hardware RAID isn’t your cup of tea though you can still opt for the SAS 5 family of controllers in your Dell box. It’s just as good as the SAS bits on all the Sun machines since they’re the exact same chip. The remote management LOM thingy does suck arse though. But so does anything except the LOM on UltraSPARC machines (and SGI Altixes).
The only 2.5″ 300gb drives I could find are SATA drive for notebooks & laptops. From what I’ve seen with the LSI SAS controllers, they would function, but I wouldn’t want to use those for any server purpose data, or anything. I’m sure 300gb 2.5″ SAS drives are in the pipe, just give it a year… I’ll bet Sun could design Galaxy machines that use 3.5″ SAS / SATA drives, but at bulk data storage, they’ll steer you towards Thumper and SAN equipment.
As far as Dell BIOS goes, BIOS is the nasty thing about x86 / x64. PC BIOSes are a slow, unintelligent, barely diagnosable (frequently undiagnosable), dirty hack. (it needs to be replaced big-time, and EFI is not the answer…) I will say a Dell PowerEdge 750 was the first system where I had a BIOS update fix an ethernet controller issue, but the fix was completely undocumented in any readme data anywhere I could find… (honestly, I’ll stop ranting at that point, I could fill pages with issues I’ve had with Dell)
hi all/ awta kaw emag aowe
I think 2.5″ 300GB drives 10K (and 15K) rpm will require area density (Gbits/in2) that is simply NOT achievable today – as they have less than half surface area compared to 3.5″ drives and possible # of platters is also smaller than in 3.5″ drives.
