One of the reasons, that the hardware didn't fly under the Oracle banner, might have been the Oracle brand itself: We used SunFires for Linux workloads quite often, but the moment they became larryated we stopped immediately.
Sure enough, for the next NTP on ILO debacle they wanted us to pay for a firmware upgrade.
Not even HP dared so...

Not to belabor the obvious, but SPARC isn't the only hardware to fly under the banner.
There's X86 too. That's still around.
Customers were very plain about it back in 2009 -2010: They did not want to deal with Oracle's BS for their hardware and OS, and many told me they had plans to, or were actively kicking Sun gear out in favor of Linux on x86. Many of the net admins and sysadmins I dealt with were heartbroken about it. They loved Solaris, the hardware AND the people of Sun who built and supported it. And they ALL detested Oracle, with their skeet you licensing practices and questionable support policies.
People loved Sun and hated ORCL. Something for the former Sun folks to never forget!
That's funny--paying for fixing a NTP vulnerability on ILOM. What's even funnier is the ILOM firmware team added a NTP server (not just a lightweight client. That does NOT belong on a system controller--not then--not now.
ILOM is just too heavyweight--has too much baggage and has too many points of access. Wall the thing off and don't put it on the network!
