I’m seeing some really “out there” marketing lately, every vendor (including us) trying to find an angle that sounds exciting while not being an outright lie (most of the time).
A competitor recently claimed an industry first of up to 1.7 million (undefined type) IOPS in a single rack.
The number (which admittedly sounds solid), got me thinking. Was the “industry first” that nobody else did up to 1.7 million IOPS in a single rack?
Would that statement also be true if someone else did up to 5 million IOPS in a rack?
I think that, in the world of marketing, it would – since the faster vendor doesn’t do up to 1.7 million IOPS in a rack, they do up to 5! It’s all about standing out in some way.
Well – let’s have some fun.
I can stuff 21x EF560 systems in a single rack.
Each of those systems can do 650,000 random 4K reads at a stable 800 microseconds (since I like defining my performance stats), 600,000 random 8K reads at under 1ms, and over 300,000 random 32KB reads at under 1ms. Also each system can do 12GB/s of large block sequential reads. This is sustained I/O straight from the SSDs and not RAM cache (the I/O from cache can of course be higher but let’s not count that).
See here for the document showing some of the performance numbers.
Well – some simple math shows a standard 42U rack fully populated with EF560 will do the following:
- 13,650,000 IOPS.
- 252GB/s throughput.
- Up to 548TB of usable SSD capacity using DDP protection (up to 639TB with RAID5).
Not half bad.
Doesn’t quite roll off the tongue though – industry first of up to thirteen million six hundred and fifty thousand IOPS in a single rack. 🙂
I hope rounding down to 13 million is OK with everyone.
